Making Nuclear Energy Sustainable Means Getting Rid of Nuclear Waste: Is this Possible?

“When using fast reactors in a closed fuel cycle, one kilogram of nuclear waste can be recycled multiple times until all the uranium is used and the actinides — which remain radioactive for thousands of years — are burned up. What then remains is about 30 grams of waste that will be radioactive for 200 to 300 years,” said Mikhail Chudakov, IAEA Deputy Director General and Head of the Department of Nuclear Energy.

Fast reactors were among the first technologies deployed during the early days of nuclear power, when uranium resources were perceived to be scarce. However, as technical and material challenges hampered development and new uranium deposits were identified, light water reactors became the industry standard. However, efforts are underway in several countries to advance fast reactor technology, including in the form of small modular reactors (SMRs) and microreactors (MRs). 

Five fast reactors are now in operation: two operating reactors (BN-600 and BN-800) and one test reactor (BOR-60) in the Russian Federation, the Fast Breeder Test Reactor in India and the China Experimental Fast Reactor. The European Union, Japan, the United States of America, the United Kingdom and others have fast reactor projects tailored to a variety of aims and functions underway, including SMRs and MRs. Russia’s Pilot Demonstration Energy Complex, which is under construction in Seversk, brings together a lead-cooled BREST-OD-300 fast reactor, a fuel fabrication and refabrication plant, and a plant for reprocessing mixed nitride uranium–plutonium spent fuel. A deep geological waste repository will also be built. The importance of this pilot project is not only to demonstrate the making of new fuel, irradiate it, and then recycle it, but to do so all on one site.

“Having the whole closed fuel cycle process on one site is good for nuclear safety, security and safeguards,” said Amparo Gonzalez Espartero, Technical Lead for the Nuclear Fuel Cycle at the IAEA. “It should also make more sense economically as the nuclear waste and materials do not need to be moved between locations — as they are currently in some countries — thereby minimizing transportation and logistical challenges.”

Projects are advancing in other countries. China is constructing two sodium cooled fast reactors (CFR-600) in Xiapu County, Fujian province. The first unit is under commissioning and is expected to be connected to the grid in 2024. In the USA, a fast reactor project backed by Microsoft co-founder Bill Gates is under development; it will not operate in a closed fuel cycle, although the country is renewing efforts to work on closed nuclear fuel cycles and use its existing nuclear waste to develop its own supply of fuel. In Europe, the MYRRHA project in Belgium is aimed towards building a lead-bismuth cooled accelerator driven system by 2036 to test its ability to break down minor actinides as part of a future fully closed fuel cycle.

The Dangers of Manic Oil Production

In a desolate stretch of desert spanning West Texas and New Mexico, drillers are pumping more crude than Kuwait. The oil production is so frenzied that huge swaths of land are literally sinking and heaving. The land has subsided by as much as 11 inches since 2015 in a prime portion of the Permian Basin, as drillers extract huge amounts of oil and water, according to a Wall Street Journal analysis of satellite data. In other areas where drillers dispose of wastewater in underground wells, the land has lifted by as much as 5 inches over the same period. Alongside crude, oil-and-gas companies are extracting gargantuan amounts of subterranean water—in the Delaware, between five and six barrels of water are produced, on average, for every barrel of oil. To dispose of it, they inject billions of barrels of putrid wastewater into underground disposal wells.

The constant extraction and injection of liquids has wrought complex geologic changes, which are raising concerns among local communities long supportive of oil and gas. Earthquakes linked to water disposal have rattled residents and prompted state regulators to step in. Some researchers worry that wastewater might end up contaminating scarce drinking-water supplies

Plastics, Nanoplastics and Heart Attacks

A Landmark treaty on plastic pollution scheduled to be adopted by the end of 2024  must put scientific evidence front and center. In the run-up to the final negotiations, researchers have been publishing more reports, data sets and models about plastics than ever before….Researchers have also organized groups, such as the Scientists’ Coalition for an Effective Plastics Treaty


The treaty was originally conceived as a mechanism to end plastic pollution, which is sometimes taken to mean driving the amount of ‘mismanaged waste’ to zero by 2040. Mismanaged waste is plastic that isn’t recycled or disposed of in a well-managed landfill or incinerator, but rather ends up loose in the environment or burned in an open pit. Annual production of plastics has grown exponentially, from about 2 million tonnes in 1950 to 460 million tonnes in 2019 (current levels are on track to triple by 2060). Mismanaged waste is hard to measure–estimates put it at 74 million tonnes each year., expect to reach, by 2050, 122 million tonnes per year, under business-as-usual projections. Unless policies change, the peak of mismanaged plastic waste “is nowhere yet in sight”, he says.

A new report from environmental-policy researcher Nihan Karali and her colleagues at Lawrence Berkeley National Laboratory in California concludes that plastic production generated the equivalent of 2.24 gigatonnes of carbon dioxide in 2019, mainly from the energy-intensive process of extracting and refining the fossil fuels used to generate the petrochemicals that make up most virgin plastic.


An individual plastic typically contains hundreds of chemicals — many of which are toxic and can leach out — that make the material more flexible, water repellent, flame retardant or resistant to ultraviolet light. Last month, researchers released a report listing 16,000 chemicals associated with plastics, of which they found at least to be 4,200 hazardous… A study published in February 2024 of some 250 people undergoing surgery showed that nano- and microplastics in carotid-artery blockages were linked to increased risk of heart attacks, strokes and death.

The Essence of a Nightmare: PFAS on Ocean Waves

PFAS, or forever chemicals, are ubiquitous in our environment. In the U.S. alone, there are more than 57,000 sites contaminated with these chemicals. They’re in our drinking water, our soil, our products—and our ocean. And according to new research, when waves crash onto shores around the world, they spray hundreds of thousands of PFAS particles into the air, creating a cycle in which these chemicals go from land to sea and back again. PFAS (per- and polyfluoroalkyl substances) are a class of synthetic chemicals largely used to make products stain-, grease-, and water-resistant. They’ve been dubbed “forever chemicals” because they don’t easily break down and so stay in our environments for thousands of years. They’re linked to harmful effects to health, including cancer, decreased fertility, developmental delays, and more.

What Do We Know about the Plastic Chemicals that Leach into Food?

Countries are currently negotiating a global plastics treaty to end plastic pollution. It is essential that the treaty addresses plastic chemicals because all plastics, from food packaging to car tires, contain thousands of chemicals that can leach into foodstuffs, homes, and the environment. Since many of these chemicals are hazardous, they can damage human health and the environment.

Plastic chemicals comprise all chemicals in plastics, including additives, processing aids, and impurities. A previous report by the United Nations Environment Program (UNEP) and other international institutions identified 13,000 plastic chemicals. The new PlastChem Report shows that there are more plastic chemicals than previously known, with over 16,000 chemicals included in the new PlastChem database that accompanies the report.
Further key findings of the report include:
• At least 4,200 plastic chemicals (or 26%) are of concern because of their high hazards to human health and the environment,
• More than 400 chemicals of concern can be present in each major plastic type, including in food packaging, and all tested plastics leached hazardous chemicals,

The report recommends : Increased transparency on the chemical composition of plastics is essential for closing data gaps, promoting a comprehensive management of plastic chemicals, and creating accountability across plastic value chains. A unified reporting, disclosure of the chemical composition of plastic materials and products as well as a “no data, no market” approach are recommended to ensure that essential
information about plastic chemicals becomes publicly available.

Chinese Gangs, Crypto Scams and the Deaths of 100,000 Americans

Chinese crime syndicates are using cryptocurrencies to launder billions of dollars, including money raised from helping supply drugs to the U.S. or scamming American victims…They are using crypto to launder the profits of drug dealing and illegal gambling, and have made huge amounts from investment scams that promise easy returns in the cryptocurrency markets. Crypto addresses linked to a group of suspected chemical traders based in China have received more than $37.8 million worth of assets since 2018 in exchange for shipping a key ingredient of fentanyl, the research firm Chainalysis said in a report in 2023. These shipments are often sent to Central America and Mexico, where drug cartels use them to manufacture the drug, which is then shipped to the U.S.

In October 2024, the U.S.’s Office of Foreign Assets Control sanctioned a network of individuals and companies based in China over the manufacturing and distribution of ingredients used in fentanyl and other drugs. Some of those individuals held cryptocurrency wallets to send and receive funds, the Treasury Department said. Fentanyl use by Americans has become a major public health issue, contributing to more than 100,000 deaths a year, according to the latest figures from the Centers for Disease Control and Prevention.

Scammers in China and Florida shared the same two crypto wallet addresses, implying they are likely parts of the same group, according to a joint investigation published in January 2024 by ChainArgos, a Singapore-based blockchain data platform, and Bitrace, a China-based blockchain research group…Chinese law-enforcement agencies across the country have investigated more than 800 cases, shut down five underground banks used to help process payments, and uncovered about $4 billion worth of funds based on blockchain data…Chinese prosecutors also have charged well-known crypto executives. Zhao Dong, founder of a major over-the-counter crypto platform in China called RenrenBit, was sentenced to seven years in prison in 2022 after providing crypto-exchange services to an illicit business involved in overseas gambling and so-called pig-butchering scams.

Tether, a stablecoin pegged to the U.S. dollar, has been used as a way for these groups to switch between different fiat currencies.

Food Security: The Silicon Valley of Seeds

The Communist Party’s top disciplinary body—after punishing graft in the military, domestic security organs and the financial sector—is now hunting officials, merchants and farmers it suspects of harvesting illicit profits from trade in grains and seeds. Tasked with being more forceful in safeguarding the nation’s “seed security,” authorities have investigated dozens of cases involving seed-related misconduct and, in several instances, imprisoned grain-sector officials on corruption charges…Officials say the goal is to stop the proliferation of fake and substandard seeds that could jeopardize food production and safety, while punishing officials, merchants and farmers who siphon agricultural subsidies and peddle low-grade seeds.

Xi has often highlighted food security as a national interest, calling on officials to ensure that China can fully nourish its 1.4 billion people. His demands have taken on greater urgency in recent years as he pushed to prepare his country for a potential confrontation with the U.S.—a major source of Chinese grain imports, including soybeans and corn—and forestall disruptions to food supplies for one of the world’s most populous nations…Today, Beijing sees the seed sector as one of several strategic industries where Western powers could flex their technological superiority to strangle a lagging China. Demonstrating his personal interest in this field, Xi has twice visited a seed-breeding base in the island province of Hainan that officials call the “Silicon Valley” of China’s seed industry.

China is the world’s largest grain producer, growing one-quarter of global supply on less than 10% of the world’s arable land. But its ability to feed its own people has slipped over recent decades by some estimates. ..Officials and state media have taken to comparing seeds to advanced semiconductor chips, a technology that China has pledged to master in its quest for a national renaissance…While China’s seed industry is strong enough to survive foreign strangulation, the country still falls behind in seed quality, according to the Farmers’ Daily, which recommended measures including “resolutely cracking down” on the trading of fake and mislabeled seeds, whereby officials and merchants defraud farmers with counterfeit or lower-grade goods marked as top-quality seeds….

Mass-Market Brain Manipulation and Human Rights

Scientific advances are rapidly making science-fiction concepts such as mind-reading a reality — and raising thorny questions for ethicists, who are considering how to regulate brain-reading techniques to protect human rights such as privacy.

On 13 July, 2023 neuroscientists, ethicists and government ministers discussed the topic at a Paris meeting organized by UNESCO, the United Nations scientific and cultural agency. Delegates plotted the next steps in governing such ‘neurotechnologies’ — techniques and devices that directly interact with the brain to monitor or change its activity. The technologies often use electrical or imaging techniques, and run the gamut from medically approved devices, such as brain implants for treating Parkinson’s disease, to commercial products such as wearables used in virtual reality (VR) to gather brain data or to allow users to control software… Neurotechnology is now a US$33 billion industry.
One area in need of regulation is the potential for neurotechnologies to be used for profiling individuals and the Orwellian idea of manipulating people’s thoughts and behaviour. Mass-market brain-monitoring devices would be a powerful addition to a digital world in which corporate and political actors already use personal data for political or commercial gain.

Commercial devices are of more pressing concern to ethicists. Companies from start-ups to tech giants are developing wearable devices for widespread use that include headsets, earbuds and wristbands that record different forms of neural activity — and will give manufacturers access to that information.

The privacy of this data is a key issue. Rafael Yuste, a neuroscientist at Columbia University in New York City, told the meeting that an unpublished analysis by the Neurorights Foundation, which he co-founded, found that 18 companies offering consumer neurotechnologies have terms and conditions that require users to give the company ownership of their brain data. All but one of those firms reserve the right to share that data with third parties. “I would describe this as predatory,” Yuste says. “It reflects the lack of regulation.”…Another theme at the meeting was how the ability to record and manipulate neural activity challenges existing human rights. Some speakers argued that existing human rights — such as the right to privacy — cover this innovation, whereas others think changes are needed.

Yuste and his colleagues propose five main neurorights: the right to mental privacy; protection against personality-changing manipulations; protected free will and decision-making; fair access to mental augmentation; and protection from biases in the algorithms that are central to neurotechnology.

Dirty Air: the Lack of Cross-Border Cooperation

An airshed is a geographical area where local topography and meteorology limit the dispersion of pollutants away from the area. Research and practice has shown that regulating pollution by taking into account airsheds, rather the arbitrary boundaries of cities and towns, can be a cost-effective way of fighting pollution.

Managing air pollution by taking into account the airsheds has done successfully in Europe and China, whose capital was once as synonymous with smog as New Delhi, India, is today. Beijing’s air is now cleaner chiefly thanks to the creation in 2013 of a powerful airshed-wide authority responsible for the capital, the city of Tianjin and 26 adjacent prefectures. In 2017 pm2.5 levels in Beijing were half those of the previous year.

India is trying to follow this example in and around Delhi. In 2021 it launched a pollution-control agency, called the Commission for Air Quality Management, with responsibility for a 55,000-square-km area, encompassing the capital and parts of Haryana, Rajasthan and Uttar Pradesh… Yet a decisive way to deal with air pollution in India will require a major expansion of this approach, according to the World  Bank.

The World Bank has identified six regional airsheds of South Asia. They are vast areas, covering multiple urban, provincial and national jurisdictions. Significantly, four of the six cross national borders. One stretches from eastern Iran into western Afghanistan and southern Pakistan; another covers much of northern India and western Bangladesh. According to the World Bank’s modelling, the more coordinated the pollution controls adopted in these airsheds, the more cost-effective and beneficial they would be.

The ideal scenario, it suggests, would be for authorities within a given airshed to co-operate, across national borders, on data-sharing and policy formulation, while each working towards a locally determined target. This would allow them to prioritize relatively easy or low-cost forms of pollution control—such as regulating brick kilns—over more difficult or expensive sorts, such as closing coal-fired power stations. The World Bank reckons that in this scenario South Asian life expectancies would rise, infant mortality would drop and health-care expenditure would fall. For a cost of $5.7bn, it estimates the approach could bring economic benefits worth $52.5bn by 2030.

The idea of Bangladesh, India and Pakistan—let alone Afghanistan and Iran—working together to such an extent… might almost seem absurd. South Asia is one of the most unneighborly, least-integrated regions in the world. It is haunted by a history of war and mutual suspicion. Its cross-border linkages are meagre. Trade within the region is just 5% of its members’ total trade…

The Shameful Mismanagement of the Murray-Darling River: Australia

Millions of fish have died in the Darling River near his town, Menindee, in outback New South Wales, Australia in March 2023. After days under the sun, their bodies had started to “break up…transforming the river that locals rely on for drinking and showering into an ecological wasteland. Authorities have said the mass death was caused by a lack of oxygen in the water, called hypoxia, a result of recent floods and a heat wave. But furious locals say the true root of the problem is the overuse of Australia’s biggest and most vital river system.

The disaster is the latest episode in a long-running battle over the Murray Darling Basin, a vast network of lakes and rivers stretching across four states in eastern Australia, which sustains much of the country’s agriculture and dozens of communities along its banks. In an arid country where social, economic and environmental interests clash whenever water runs scarce, the issue has pitted states against each other, and riverside communities against farms upstream.

The 2019 fish deaths happened during a drought and the 2023 fish deaths happened after a flood, said Richard Kingsford, the director of the Center for Ecosystem Science at the University of New South Wales. But, he said, the long-term causes were the same both times: “There’s not enough water in the river, and the whole system is engineered so that escape routes are closed.” Over-extraction means parts of the river run dry more often, he said, and the small and medium-sized floods that used to periodically clear away organic debris have all but disappeared. That means when a big flood hits, that debris is all swept into the river, where it breaks down and deoxygenates the water. That, combined with the construction of weirs that have prevented the fish from swimming to better-oxygenated water, has made this disaster worse, he said….

The New South Wales fisheries and water management bodies, by contrast, both attribute the disaster to weather-related causes…

After many of the fish had already sunk to the bottom of the river, the cleanup started with workers in small boats removing floating carcasses with hand-held nets. Authorities said this will be followed by machinery that will drag nets through the river to scoop up sunken fish….

Playing Fast and Loose with Nuclear Substances: a missing radioactive capsule

In the Australian Outback, authorities are engaged in an unusual search-and-recovery effort. Gone missing is a capsule less than an inch long of radioactive material that can burn or sicken anyone who touches it. Their problem is that it could be anywhere along a 900-mile stretch of highway connecting a Rio Tinto PLC mine to Perth, Western Australia’s state capital…The capsule, which is 8-millimeters (about 5/16s of an inch) long and contains a small quantity of radioactive Cesium-137, worked its way loose from a piece of equipment that Rio Tinto had sent to Perth by truck for repair.

The tiny capsule fell along a route that is almost the distance between New York and St. Louis. Complicating the search effort is a gap of nearly two weeks between when the equipment left Rio Tinto’s Gudai-Darri mine on Jan. 12, 2023 and when the capsule was discovered to be missing on Jan. 25… Authorities worry the capsule could have become lodged in a tire of any of the vehicles that use the highway, potentially exposing their occupants to radiation levels that they compare to receiving around 10 X-rays in an hour. Exposure could cause radiation burns or severe illness, said Andrew Robertson, Western Australia’s chief health officer.

A Costly Affair: Japan’s Nuclear Waste Legacy

The Japan Atomic Energy Agency estimates that it will cost taxpayers 36.1 billion yen ($280 million) to rectify the shoddy storage of radioactive waste in a storage pool at the Tokai Reprocessing Plant, the nation’s first facility for reprocessing spent nuclear fuel, 

Around 800 containers of transuranic radioactive waste, or “TRU waste,” were dropped into the pool from 1977 to 1991 using a wire in the now-disused plant in Tokai, a village in Ibaraki Prefecture northeast of Tokyo. They emit high levels of radiation. The waste includes pieces of metal cladding tubes that contained spent nuclear fuel, generated during the reprocessing process. The containers are ultimately supposed to be buried more than 300 meters below surface.

The agency has estimated that 19.1 billion yen will be needed to build a new storage facility for the containers, and 17 billion yen for a building that will cover the storage pool and the crane equipment to grab containers. The 794 containers each are about 80 centimeters in diameter, 90 cm tall and weigh about 1 ton, with many lying on their sides or overturned in the pool. Some have had their shape altered by the impact of being dropped. The containers were found stored in the improper manner in the 1990s. While the agency said the storage is secure from earthquakes and tsunamis, it has nonetheless decided to improve the situation. The extractions have been delayed by about 10 years from the original plan and are expected to begin in the mid-2030s.

The Tokai Reprocessing Plant was the nation’s first plant that reprocessed spent fuel from nuclear reactors to recover uranium and plutonium. Between 1977 and 2007, about 1,140 tons of fuel were reprocessed. The plant’s dismantlement was decided in 2014 and is expected to take about 70 years at a cost of 1 trillion yen.

New Drugs: Animals Stuck to the Seabed

Biologists are working with engineers to develop new tools to accelerate the development of medicines derived from marine animals, focusing on ocean-going robots with onboard DNA-sequencing gear. They foresee fleets of autonomous submersible robots trolling the ocean like electronic bloodhounds to sniff out snippets of the animals’ DNA in seawater—and then gathering and analyzing this so-called environmental DNA, or eDNA.

“The ultimate goal is an underwater vehicle that collects environmental DNA samples, sequences them and then sends the data back to the lab,” says Kobun Truelove, senior research technician at the Monterey Bay Aquarium Research Institute in California. “We would like to set up a network where you would have these autonomous vehicles out there sampling and then basically be getting the data back in real time.”

More than 1,000 marine-organism-derived compounds have shown anticancer, antiviral, antifungal or anti-inflammatory activity in medical assays, according to a database compiled by the Midwestern University Department of Marine Pharmacology. The U.S. Food and Drug Administration has approved 15 drugs derived from marine organisms, including ones for chronic pain and high cholesterol. Another 29 marine animal-derived compounds are now in clinical trials, according to the database.

Marine invertebrates are a key target of biomedical research because the animals—mostly attached to the seabed and unable to move—have evolved sophisticated chemical defenses to fend off fish, turtles and other predators in their environment. Research has shown that the natural toxins that comprise these defenses can be toxic to cancer cells and human pathogens. These sea creatures “make a broad range of different chemistries, things that synthetic chemists never thought of making,” says Barry O’Keefe, who have also identified compounds produced by bacteria living symbiotically with marine invertebrates. Once scientists have a suitable sample of eDNA and it’s been sequenced, they say, they can identify compounds the organisms are capable of producing. Then researchers can synthesize the compounds and test them to see if they have medicinal properties…

Collection of eDNA promises to be faster and less costly than the complex method commonly used   collect marine specimens—one that Amy Wright, director of the natural products group at Florida Atlantic University’s Harbor Branch Oceanographic Institution, likens to a treasure hunt. Currently, research vessels on weekslong expeditions launch submersible vehicles equipped with clawlike grabbers and suction tubes for gathering specimens. Once the vehicles and their payload are back on the ships, researchers preserve them and deliver them to labs, where their genomes are sequenced. The entire process can take weeks and is expensive. Just paying the crew to operate a research vessel for a single day can cost $35,000, according to the National Science Foundation.

Stopping the Bleeding of the Horseshoe Crab

Every April in South Carolina, fishermen catch hundreds of horseshoe crabs as they crawl onto shore to mate. The crabs are transported to labs owned by Charles River, an American pharmaceutical company, in Charleston. There they are strapped to steel countertops and, still alive, drained of about a third of their blue-colored blood. Then they are returned to the ocean. This liquid is vital for America’s biomedical industry. A liter of it goes for as much as $15,000. Bleeding is not without harm to the crabs. Conservationists estimate that between 5% and 30% of them die on release…In 2016 the International Union for Conservation of Nature listed them as “vulnerable” to extinction… 

Parts of modern medicine have been unusually reliant on the horseshoe crab. Its blood is the only known natural source of limulus amebocyte lysate (LAL), an extract that detects endotoxin, a nasty and sometimes fatal bacterium. Drug firms use it to ensure the safety of medicines and implanted devices, including antibiotics, anti-cancer drugs, heart stents, insulin and vaccines. The immune cells in the crab’s blood clot around toxic bacteria, giving a visual signal of unwanted contamination. As pharmaceutical companies ramped up production of the covid-19 jab, demand for the blue liquid soared. In 2020 nearly 650,000 crabs were bled in America, 36% more than in 2018.

As crab numbers fall and demand for LAL rises, America’s biomedical industry will face a crunch. Yet a synthetic alternative to LAL is already available and used in China and Europe.

How Forests Create Clouds and Cool the Earth

Tropical forests have a crucial role in cooling Earth’s surface by extracting carbon dioxide from the air. But only two-thirds of their cooling power comes from their ability to suck in CO2 and store it. The other one-third comes from their ability to create clouds, humidify the air and release cooling chemicals. This is a larger contribution than expected for these ‘biophysical effects’ says Bronson Griscom, a forest climate scientist.

The analysis, published in Frontiers in Forests and Global Change in March 2022, could enable scientists to improve their climate models, while helping governments to devise better conservation and climate strategies. The findings underscore growing concerns about rampant deforestation across the tropics. Scientists warn that one-third of the world’s tropical forests have been mown down in the past few centuries, and another one-third has been degraded by logging and development. This, when combined with climate change, could transform vast swathes of forest into grasslands

Trees in the tropics provide shade, but they also act as giant humidifiers by pulling water from the ground and emitting it from their leaves, which helps to cool the surrounding area in a way similar to sweating, Griscom says. “If you go into a forest, it immediately is a considerably cooler environment,” he says.

This transpiration, in turn, creates the right conditions for clouds, which like snow and ice in the Arctic, can reflect sunlight higher into the atmosphere and further cool the surroundings. Trees also release organic compounds — for example, pine-scented terpenes — that react with other chemicals in the atmosphere to sometimes create a net cooling effect… When they considered only the biophysical effects, the researchers found that the world’s forests collectively cool the surface of the planet by around 0.5 °C.

Threats to tropical rainforests are dangerous not only for the global climate, but also for communities that neighbour the forests, Lawrence says. She and her colleagues found that the cooling caused by biophysical effects was especially significant locally. Having a rainforest nearby can help to protect an area’s agriculture and cities from heatwaves, Lawrence says. “Every tenth of a degree matters in limiting extreme weather. And where you have forests, the extremes are minimized.”

Under Chemical Attack: the Human Body

The European Food Safety Authority (EFSA) has proposed reducing by a factor of 100,000 the tolerable daily intake of bisphenol A (BPA), an endocrine disruptor that interferes with hormone systems and has been linked to disease. The huge reduction could lead to a de facto ban on the cheap and durable material in food-related uses, such making plastic water bottler or lining metal cans. And it could mark a shift in how European regulators use research findings in setting exposure limits. Traditionally, those limits have been shaped by large studies directly linking a chemical to an increased risk of disease. In this case, however, risk assessors put greater weight on smaller studies showing low levels of BPA can cause subtle changes that could lead to future health problems. This approach, if adopted widely, could justify much lower exposure limits for other chemicals.

“It’s a big deal,” says Laura Vandenberg, an endocrinologist at the University of Massachusetts, Amherst, who calls the proposed limit “a gravestone for BPA in Europe.” Environmental and public health advocates are praising the proposal, which is open for comment until 22 February. Industry groups, however, are dismayed. Plastics Europe argues EFSA ignored relevant, older studies in setting the standard…

Bisphenol A is used in many plastics, including thermal paper for receipts, but most people are exposed through food. BPA leaches out of polycarbonates used to make bottles and food containers, for example, as well as the epoxy liners used to protect steel and aluminum cans from acidic food and beverages….

In the United States, a number of groups recently urged FDA to follow EFSA’s lead and consider new limits on BPA. Others note that people are often exposed to BPA in combination with other chemicals, which could increase the risk from low doses. F

Even if Europe adopts the new standard, public health advocates worry manufacturers will replace BPA with very similar chemicals, such as bisphenol S (BPS), that have also been linked to health effects. “We don’t want to see this assessment repeated for the BPS or BPF [bisphenol F] and need more decades of risk assessment,” says Ninja Reineke, head of science at the CHEM Trust, an advocacy group that focuses on environmental and health impacts of endocrine disruptors.

To avoid that problem, many advocates have called for regulators around the world to set limits for whole classes of related compounds, rather than consider them one by one. For now, Vandenberg says, regulators are simply playing “chemical whack-a-mole.”

Treating People Like Roaches-no longer legal

Since its adoption in 1993, the Chemical Weapons Convention has banned the development, possession, and use of weaponized toxic chemicals.  However, whether this prohibition also applied to law enforcement use of certain agents that act on the central nervous system (CNS) remained the subject of debate. In December 2021,  Chemical Weapons Convention adopted a landmark Decision to effectively outlaw the aerosolized use of CNS-acting chemical agents for law enforcement purposes.  

Although 85 countries supported the Decision, including Australia, Switzerland, and the United States, the vote was opposed by 10 countries, which may not feel constrained by its prohibitions. Notable among the opponents was Russia, whose security forces used aerosolized fentanyl derivatives to end the 2002 Moscow theater siege, causing the deaths of more than 120 hostages from poisoning and asphyxiation. Subsequent dual-use research into CNS-acting chemicals has been reported by Russian scientists as well as scientists from China and Iran, who also opposed this Decision.

Furthermore, the Decision is limited in scope. It explicitly prohibits only aerosolized CNS weapons, excluding other delivery mechanisms such as law enforcement dart guns…

Rapes and Razor Blades: Raping Children to Death in War Zones

Sexual abuse of young children happens all around the world. But children living in war-torn countries are at much higher risk. Those in countries recovering from conflict, such as Liberia, may also face greater dangers. The UN has recorded 15,000 cases of rape and sexual violence against children in conflict zones over the past 15 years. This, it warns, is probably a fraction of the true number. Around 72m children live in war zones in which fighters sexually attack children, according to research by Ragnhild Nordås of the University of Michigan and co-authors. That is almost ten times the number in 1990. In 2021, Liberia recorded 1,275 sexual assaults or rapes of people of all ages, according to official figures. Fully 10% of the victims were younger than six and 36% were younger than 13.

At a sexual-violence clinic in Monrovia, the capital, a nurse recounts how an eight-month-old baby was raped by her step father. A soft toy to comfort children perches on the examination table next to a large doll which young victims, often unable to speak, can point at to show what happened to them… In 2020,  another three-year-old was lured away from a water pump by a 15-year-old who used a razor blade to cut open her genital area to penetrate her. That attack caused large protests in Monrovia, which prompted President George Weah to declare rape a “national emergency”.

Why so many men rape young children in war and its aftermath is not well understood. Some experts think that war warps not just morality but also common sense. Between 2013 and 2016 in Kavumu, a village in eastern Congo, at least 11 men kidnapped and raped about 40 girls under the age of ten. Some were as young as 18 months. After each rape the men would take some blood from the victim’s hymen, believing this would protect them from bullets in battle. In 2017 a court convicted the 11 men of murder and rape.

Many of their victims were treated at Panzi Hospital, which was founded by Denis Mukwege, who was jointly awarded the Nobel peace prize in 2018 for his efforts to end sexual violence in war. The number of babies and infants treated for rape at the hospital dipped in the year after the trial, says Sylvain Mwambali, a doctor who works there. But it soon shot up again, to a higher level than in the three years before the convictions. In the past three years the hospital has treated 103 raped children aged five or younger, or about one every ten days. In 2020 Dr Mwambali treated a baby just a few months old whose vagina and intestines were mutilated by rape. “I could not sleep for weeks,” she says. “How can someone carry on, creating a wound like that? She would have been suffering, crying, they destroyed her vulva, up until the anus, yet they continued.”

Sometimes rebels may rape children to terrorise and control the population. Other men may copy them, perhaps because it makes them feel powerful. A breakdown in law and order may allow rapists to escape any punishment. “There is a social deterioration,” says Dr Mwambali. “People can rape your mother in front of you…there are rapes in churches.” In Liberia, warped beliefs of a different kind are a common explanation for why men rape young children. Some traditional healers tell people, “If you have intercourse with a young girl, you will become rich,” says Margaret Taylor of Women Empowerment Network, an NGO. “The younger the person is, the more riches they get.”

Are We Transgressing the Planetary Boundaries?

There are an estimated 350,000 different types of manufactured chemicals on the global market. These include plastics, pesticides, industrial chemicals, chemicals in consumer products, antibiotics and other pharmaceuticals….The rate at which these pollutants are appearing in the environment far exceeds the capacity of governments to assess global and regional risks, let alone control any potential problems..

In 2009, an international team of researchers identified nine planetary boundaries that demarcate the remarkably stable state Earth has remained within for 10,000 years – since the dawn of civilization. These boundaries include greenhouse gas emissions, the ozone layer, forests, freshwater and biodiversity. The researchers quantified the boundaries that influence Earth’s stability, and concluded in 2015 that four boundaries have been breached. But the boundary for chemicals was one of two boundaries that remained unquantified.

This new research takes this a step further. The researchers say there are many ways that chemicals and plastics have negative effects on planetary health, from mining, fracking and drilling to extract raw materials to production and waste management.

Some of these pollutants can be found globally, from the Arctic to Antarctica, and can be extremely persistent…Global production and consumption of novel entities is set to continue to grow. The total mass of plastics on the planet is now over twice the mass of all living mammals, and roughly 80% of all plastics ever produced remain in the environment. Plastics contain over 10,000 other chemicals, so their environmental degradation creates new combinations of materials – and unprecedented environmental hazards. Production of plastics is set to increase and predictions indicate that the release of plastic pollution to the environment will rise too, despite huge efforts in many countries to reduce waste.

Detoxing the Fish of Our Lakes and Rivers

Fish populations appear to recover rapidly from mercury pollution once humans stop adding it to their environment. A 15-year study of a lake in Canada found that eight years after the metal’s supply ceased, concentrations of methylmercury – a highly toxic substance made from mercury by bacteria in aquatic ecosystems – fell by 76 per cent… 

“I can’t imagine a much faster recovery,” says Paul Blanchfield at government agency Fisheries and Oceans Canada, who led the research. The team are not suggesting the fish excrete the mercury quickly – the experiment in fact shows they hang on to it for a long time – but that quick turnover of generations sees concentrations fall fast when new pollution stops.

Mercury pollution is still a major global environmental problem, with small-scale gold mining and coal burning being the two biggest sources. Transported in the atmosphere and rained down on lakes and oceans, the metal’s accumulation in freshwater and marine species has raised concerns over the human health impact of eating fish.

A Breach Too Far: 413 PPM

The abundance of heat-trapping greenhouse gases in the atmosphere once again reached a new record in 2021, with the annual rate of increase above the 2011-2020 average. That trend has continued in 2021, according to the World Meteorological Organization (WMO) Greenhouse Gas Bulletin.

Concentration of carbon dioxide (CO2), the most important greenhouse gas, reached 413.2 parts per million in 2020 and is 149% of the pre-industrial level. Methane (CH4) is 262% and nitrous oxide (N2O)  is 123% of the levels in 1750 when human activities started disrupting Earth’s natural equilibrium.

Roughly half of the CO2 emitted by human activities today remains in the atmosphere. The other half is taken up by oceans and land ecosystems. The Bulletin flagged concern that the ability of land ecosystems and oceans to act as “sinks” may become less effective in future, thus reducing their ability to absorb carbon dioxide and act as a buffer against larger temperature increase…Such changes are already happening, for example, transition of the part of Amazonia from a carbon sink to a carbon source

The Bulletin shows that from 1990 to 2020, radiative forcing – the warming effect on our climate – by long-lived greenhouse gases increased by 47%, with CO2 accounting for about 80% of this increase…The amount of CO2 in the atmosphere breached the milestone of 400 parts per million in 2015. And just five years later, it exceeded 413 ppm. 

“Carbon dioxide remains in the atmosphere for centuries and in the ocean for even longer. The last time the Earth experienced a comparable concentration of CO2 was 3-5 million years ago, when the temperature was 2-3°C warmer and sea level was 10-20 meters higher than now. But there weren’t 7.8 billion people then,” said Prof. Taalas.

How to Suck Carbon and Convert it to Rocks

The Orca carbon-capture plant, just outside Reykjavik in Iceland, has switched on its fans and began sucking carbon dioxide from the air since September 2021. The sound was subtle—a bit like a gurgling stream. But the plant’s creators hope it will mark a big shift in humanity’s interaction with the climate. Orca is, for now, the largest installation in the infant “direct air capture” industry, which aims to remove CO2 from the atmosphere. When sealed underground such CO2 counts as “negative emissions”—an essential but underdeveloped method for tackling global warming.

Thus, the full operation extracts CO2 from air and turns it to rock. Trials have shown that Icelandic basalts can sequester CO2 in solid rock within two years. Power comes from a nearby geothermal power station….One catch is volume. Orca will capture 4,000 tonnes of carbon dioxide a year, out of around 35bn tonnes produced by burning fossil fuels. Another is cost. It costs Orca somewhere between $600-800 to sequester one tonne of carbon dioxide, and the firm sells offset packages online for around $1,200 per tonne. The company thinks it can cut costs ten-fold through economies of scale. But there appears to be no shortage of customers willing to pay the current, elevated price. Even as Orca’s fans revved up, roughly two-thirds of its lifetime offering of carbon removals had already been sold. Clients include corporations seeking to offset a portion of their emissions, such as Microsoft, Swiss Re as well as over 8,000 private individuals.

Climeworks is not alone in having spotted the opportunity. Using different chemistry, Carbon Engineering, a Canadian company, is gearing up to switch on its own carbon-scrubbing facilities. It will take more than these pioneer engineers and financiers to build a gigatonne-sized industry. But the fans are turning.

The $22 Trillion Global Carbon Market

Two of the world’s biggest oil companies, Royal Dutch Shell  and BP already have significant carbon-emissions trading arms, thanks to a relatively well-developed carbon market in Europe. Big carbon emitters such as steel producers receive emission allowances, and can buy more to stay under European emissions guidelines. Companies that fall below those limits can sell their excess carbon-emissions allowances.

Carbon traders get in the middle of those transactions, seeking to profit from even small moves in the price of carbon and sometimes betting on the direction of prices. The value of the world’s carbon markets—including Europe and smaller markets in places such as California and New Zealand—grew 23% last year to €238 billion, equivalent to $281 billion.

That is small compared with the world’s multitrillion-dollar oil markets and to other heavily traded energy markets, such as natural gas or electricity. But growth potential exists, the industry says. Wood Mackenzie, an energy consulting firm, estimates a global carbon market could be worth $22 trillion by 2050… An experienced carbon trader’s base salary can be roughly $150,000 to $200,000, although a lot of compensation occurs via bonuses, traders said…. BP’s overall annual trading profits were between $3.5 billion and $4 billion during the past two years, according to a person familiar with the matter.

The 17 000 Nuclear Objects Dumped in the Kara Sea


“Having the exact coordinates for the dumped container with the nuclear reactors from K-19 submarine is undoubtedly good news,” says nuclear safety expert Andrey Zolotkov. Zolotkov hopes for risk assessments to be carried out soon with the aim to see how the nuclear reactors could be lifted out of the maritime environment and brought to a yard for safe decommissioning…More than 50 years have passed since the dumping.

In the so-called “White Book” on dumped nuclear objects, originally published by President Boris Yeltsin’s environmental advisor Alexei Jablokov, the dumping of the submarine’s two reactors is listed for the Abrosimova Bay on the east coast of the Kara Sea, but exact location hasn’t been confirmed.

It was in August 2021 that the the crew on “Akademik M. Keldysh” with the help of sonars and submersibles found the container. Both marine researchers, oceanology experts from Russia’s Academy of Science and representatives of the Ministry of Emergency Situations are working together in the expedition team.

K-19 is one of the most infamous nuclear-powered submarines sailing for the Soviet navy’s Northern Fleet. In July 1961 the reactor lost coolant after a leak in a pipe regulating the pressure to the primary cooling circuit. The reactor water started boiling causing overheating and fire. Crew members managed to extinguish the fire but had big problems fixing the leak in an effort to save the submarine from exploding. Many of them were exposed to high doses of radioactivity before being evacuated to a nearby diesel submarine sailing in the same area of the North Atlantic. Eight of the crew members who had worked on the leak died of radiation poisoning within a matter of days.

The submarine was towed to the Skhval shipyard (No. 10) in Polyarny. Later, the reactor compartment was cut out and a new installed. The two damaged reactors, still with spent nuclear fuel, were taken north to the Kara Sea and dumped. Keeping the heavily contaminated reactors at the shipyard was at the time not considered an option.

In the spring of 2021, Russia’s Foreign Ministry invited international experts from the other Arctic nations to a conference on how to recover sunken radioactive and hazardous objects dumped by the Soviet Union on the seafloor east of Novaya Zemlya. Moscow chairs the Arctic Council for the 2021-2023 period. 

The two reactors from the K-19 submarine are not the only objects posing a risk to marine environment. In fact, no other places in the world’s oceans have more radioactive and nuclear waste than the Kara Sea. Reactors from K-11 and K-140, plus the entire submarine K-27 and spent uranium fuel from one of the old reactors of the “Lenin” icebreaker are also dumped in the same sea. While mentality in Soviet times was «out of sight, out of mind», the Kara Sea seemed logical. Ice-covered most of the year, and no commercial activities. That is changing now with rapidly retreating sea ice, drilling for oil-, and gas, and increased shipping…Additional to the reactors, about 17,000 objects were dumped in the Kara Sea in the period from the late 1960s to the early 1990s.

Measuring Methane Emissions

The American gas industry faces growing pressure from investors and customers to prove that its fuel has a lower-carbon provenance to sell it around the world. That has led the top U.S. gas producer, EQ , and the top exporter, Cheniere Energy to team up and track the emissions from wells that feed major shipping terminals. The companies are trying to collect reliable data on releases of methane—a potent greenhouse gas increasingly attracting scrutiny for its contributions to climate change—and demonstrate they can reduce these emissions over time.

“What we’re trying to really do is build the trust up to the end user that our measurements are correct,” said David Khani, EQT’s chief financial officer. “Let’s put our money where our mouth is.” Natural gas has boomed world-wide over the past few decades as countries moved to supplant dirtier fossil fuels such as coal and oil. It has long been touted as a bridge to a lower-carbon future. But while gas burns cleaner than coal, gas operations leak methane, which has a more potent effect on atmospheric warming than carbon dioxide, though it makes up a smaller percentage of total greenhouse gas emissions.

Investors, policy makers and buyers of liquefied natural gas, known as LNG, are rethinking the fuel’s role in their energy mix …Those concerns, pronounced in Europe and increasingly in Asia, are a problem for LNG shippers, as some of their customers signal plans to ease gas consumption over time…Nearly every industry now faces some pressure to reduce its carbon footprint, as investors focus more on ESG—or environmental, social and governance—issues and push companies for trustworthy emissions data. But the pressure has become particularly acute for oil-and-gas companies, whose main products contribute directly to climate change.

The companies and researchers plan to test drones, specialized cameras that can see methane gas, and other technologies across about 100 wells in the Marcellus Shale in the northeast U.S., the Haynesville Shale of East Texas and Louisiana, and the Permian Basin of West Texas and New Mexico. EQT has said it would spend $20 million over the next few years to replace leaky pneumatic devices, which help move fluids from wells to production facilities and water tanks, with electric-drive valves, executives said. They expect that will cut about 80% of the company’s methane emissions. The company also began exclusively using electric-powered hydraulic fracturing equipment last year.

Imagining Failure: Nuclear Waste on the Beach, California

But for all the good vibes and stellar sunsets of  San Onofre state beach in California, beneath the surface hides a potential threat: 3.6m lb of nuclear waste from a group of nuclear reactors shut down nearly a decade ago. Decades of political gridlock have left it indefinitely stranded, susceptible to threats including corrosion, earthquakes and sea level rise. The San Onofre reactors are among dozens across the United States phasing out, but experts say they best represent the uncertain future of nuclear energy.

“It’s a combination of failures, really,” said Gregory Jaczko, who chaired the US Nuclear Regulatory Commission (NRC), the top federal enforcer, between 2009 and 2012, of the situation at San Onofre. That waste is the byproduct of the San Onofre Nuclear Generating Station (Songs), three nuclear reactors primarily owned by the utility Southern California Edison (SCE) that has shut down….

Since there is not central repository for the final disposition of nuclear wasted in the United States,  the California Coastal Commission approved in 2015 the construction of an installation at San Onofre to store it until 2035. In August 2020, workers concluded the multi-year burial process, loading the last of 73 canisters of waste into a concrete enclosure. San Onofre is not the only place where waste is left stranded. As more nuclear sites shut down, communities across the country are stuck with the waste left behind. Spent fuel is stored at 76 reactor sites in 34 states….

At San Onofre, the waste is buried about 100ft from the shoreline, along the I-5 highway, one of the nation’s busiest thoroughfares, and not far from a pair of faults that experts say could generate a 7.4 magnitude earthquake. Another potential problem is corrosion. In its 2015 approval, the Coastal Commission noted the site could have a serious impact on the environment in case of coastal flooding and erosion hazards beyond its design capacity, 

Concerns have also been raised about government oversight of the site. Just after San Onofre closed, SCE began seeking exemptions from the NRC’s operating rules for nuclear plants. The utility asked and received permission to loosen rules on-site, including those dealing with record-keeping, radiological emergency plans for reactors, emergency planning zones and on-site staffing.

San Onofre isn’t the only closed reactor to receive exemptions to its operating licence. The NRC’s regulations historically focused on operating reactors and assumed that, when a reactor shut down, the waste would be removed quickly.

It’s true that the risk of accidents decreases when a plant isn’t operating, said Dave Lochbaum of the Union of Concerned Scientists. But adapting regulations through exemptions greatly reduces public transparency, he argued. “Exemptions are wink-wink, nudge-nudge deals with the NRC,” he said. “In general, it’s not really a great practice,” former NRC chair Jaczko said about the exemptions. “If the NRC is regulating by exemption, it means that there’s something wrong with the rules … either the NRC believes the rules are not effective, and they’re not really useful, or the NRC is not holding the line where the NRC should be holding line,” he said…

It’s worth considering how things fail, though, argued Rod Ewing, nuclear security professor at Stanford University’s center for international security and cooperation, and author of a 2021 report about spent nuclear waste that focuses on San Onofre. “The problem with our safety analysis approach is we spend a lot of time proving things are safe. We don’t spend much time imagining how systems will fail,” he said. “And I think the latter is what’s most important.”

Decoding Brain Signals with a Credit Card

A man unable to speak after a stroke has produced sentences through a system that reads electrical signals from speech production areas of his brain, researchers reported in July 2021…The participant had a stroke more than a decade ago that left him with anarthria—an inability to control the muscles involved in speech. Because his limbs are also paralyzed, he communicates by selecting letters on a screen using small movements of his head, producing roughly five words per minute.

To enable faster, more natural communication, neurosurgeon Edward Chang of the University of California, San Francisco, tested an approach that uses a computational model known as a deep-learning algorithm to interpret patterns of brain activity in the sensorimotor cortex, a brain region involved in producing speech . The approach has so far been tested in volunteers who have electrodes surgically implanted for non-research reasons such as to monitor epileptic seizures.

In the new study, Chang’s team temporarily removed a portion of the participant’s skull and laid a thin sheet of electrodes smaller than a credit card directly over his sensorimotor cortex. To “train” a computer algorithm to associate brain activity patterns with the onset of speech and with particular words, the team needed reliable information about what the man intended to say and when….So the researchers repeatedly presented one of 50 words on a screen and asked the man to attempt to say it on cue. Once the algorithm was trained with data from the individual word task, the man tried to read sentences built from the same set of 50 words, such as “Bring my glasses, please.” 


With the new approach, the man could produce sentences at a rate of up to 18 words per minute, Chang says…The system isn’t ready for use in everyday life, Chang notes. Future improvements will include expanding its repertoire of words and making it wireless, so the user isn’t tethered to a computer roughly the size of a minifridge.

Sponsors of War: Captagon at $25 Better than Alcohol

In Saudi Arabial party-goers prefer Captagon pills (to alcohol), nowadays the Gulf’s favorite drug, at $25 a pop. Part of the amphetamine family, it can have a similar effect to Viagra—and conquers sleep. “With one pill,” says a raver, “we can dance all weekend.”

For Syria’s president, Bashar al-Assad, the drug has become a boon—at least in the short run. His country has become the world’s prime pusher of Captagon. As the formal economy collapses under the burden of war, sanctions and the predatory rule of the Assads, the drug has become Syria’s main export and source of hard currency. The Centre for Operational Analysis and Research (COAR), a Cyprus-based consultancy, reckons that last year authorities elsewhere seized Syrian drugs with a street value of no less than $3.4bn. That compares with Syria’s largest legal export, olive oil, which is worth some $122m a year. The drug is financing the central government, says Ian Larson, who wrote a recent report on the subject for COAR…

Chemical plants in the cities of Aleppo and Homs have been converted into pill factories. In the Gulf the mark-up for pills can be 50 times their cost in Syria. Smugglers hide them in shipments of paper rolls, parquet flooring and even pomegranates. Saudi princes use private jets to bring the stuff in

For the Syrians left behind, drugs may destroy what remains of society after a decade of civil war. “Young men who haven’t been killed, exiled or jailed are addicts,” says a social worker in Sweida, a city held by the Assads in the south.

The Necessity of the Evil: Breeding Monkeys to Experiment with their Brains

In 2014 a German animal-rights group called soko Tierschutz planted a caretaker in the laboratory of Nikos Logothetis, a neuroscientist working at the Max Planck Institute in Tübingen. The infiltrator secretly filmed around 100 hours of lab work over six months, some of which was later broadcast on German television. The footage showed monkeys with metal plugs grafted into their skulls—ports which researchers used to probe and study their brains. One vomits on camera, apparently as a result of damage done to blood vessels in its brain while electrodes were inserted.

The impact was immediate and lasting. Around 800 people massed outside Dr Logothetis’s lab, demanding an end to his work with monkeys. He was called a monster and a murderer. He and his family received death threats. He faced charges (which were dismissed) of breaking German animal-welfare laws. So in 2020 he announced that his laboratory would move to China. He is building a new research facility in Shanghai, working with Mu-ming Poo of the Institute of Neuroscience, one of China’s leading brain researchers, who was on the team responsible for first cloning a genetically modified primate in 2018. 

In East Asia, particularly China and Japan, the volume of research carried out on monkeys is growing. Most of this has been driven by creating and expanding domestic primate-research programmes. Leading institutions such as the Shanghai Institute of Neuroscience focus on breeding monkeys whose genomes have been modified in order to make their physiology more like humans’ and so more useful for studying human diseases.

The social nature of monkeys and their intelligence—which is why they are so useful for research—also help explain why such experiments are so troubling. Research which relies on them is simultaneously more valuable and more ethically fraught than research on other creatures. Neuroscientists in particular consider monkeys irreplaceable. The brain is so poorly understood that looking at its activity in living creatures is the only way to fathom how it works, says Dr Treue. Dissecting dead brains produces only limited information. Brains only really make sense when active. Few humans would volunteer to have electrodes implanted in their brains. The consent of any who did would be suspect….

The list of medical advances which rest on animal experimentation is long, but Dr Bennett points to one in particular that could not have happened without monkeys: prosthetic limbs which “talk” to the brain, known as neural prosthetics. The brains of non-human primates are sufficiently similar to ours to allow for a prosthetic developed on monkeys to be used by humans. They are still rare, but prototypes have restored the power to interact with the physical world to people who have lost the use of their own limbs.

China is becoming the global centre for the kind of neuroscience that uses monkeys. And the stakes are getting higher. Neurological disorders are the world’s second-leading cause of death after heart disease. Conditions such as Parkinson’s disease, Alzheimer’s and dementia are becoming more burdensome as the world gets greyer. Meanwhile technology companies hope that an understanding of the brain can help them build cleverer software. Generals think advances in neuroscience can help them build better weapons.

The pandemic has bolstered China’s position. In February 2020 China’s government banned the export of all wild animals in an effort to tamp down the wildlife trade that is thought to be a vector for the zoonotic spillover of pathogens such as sars-cov-2, the virus that causes covid-19. Exceptions for research are subject to the government’s approval. Until recently the majority of monkeys used in America were imported from farms in China. But export controls have created shortages. China has decided that research primates are a strategic resource. Exports are unlikely to revert to their previous levels…America and Europe may find themselves outsourcing the creation of knowledge that relies on research methods they consider unethical. In future they may have to choose between relying on the fruits of that knowledge, such as treatments for neurological disorders, and rejecting them in principle….

The Trillion Dollar Mess: Taking Down the Oil Infrastructure

Some of the world’s largest oil companies have been ordered to pay part of a $7.2 billion tab to retire hundreds of aging wells in the Gulf of Mexico that they used to own, capping a case that legal experts say is a harbinger of future battles over cleanup costs.

A federal judge ruled last month that Fieldwood Energy a privately held company that currently controls the old wells and had sought bankruptcy protection, could pass on hundreds of millions of dollars in environmental liabilities to prior owners and insurers of the wells as part of its reorganization plan. Exxon Mobil,  BP, Hess , Royal Dutch Shell and insurance companies had objected to the plan. The dispute, litigated for months in federal bankruptcy court in Houston, centered over who should bear the enormous costs of capping and abandoning wells, primarily in the shallow waters of the Gulf of Mexico where an oil spill could wreak havoc. The companies could still appeal the ruling…

Jason Bordoff, founding director of Columbia University’s Center for Global Energy Policy said that the expenses to decommission oil-and-gas infrastructure world-wide will in the trillions of dollars. “Who bears the costs?” he said. “There will be people who want to pass the buck.”

BP and Shell have pledged to reduce their carbon emissions to zero by 2050. To accomplish that, those companies will have to sell off some oil-and-gas wells to get their related emissions off their books, say energy analysts. But such asset sales present huge risks for big oil companies because many of the buyers are smaller, privately held firms, like Fieldwood, which may not have the financial wherewithal to bear cleanup costs, Ms. Usoro said. This was Fieldwood’s second bankruptcy in two years.

These smaller companies buy the wells for pennies on the dollar and assume the cleanup expenses in the hope that they can reduce the assets’ cost structure and squeeze out the remaining barrels of oil profitably. “I’ve always questioned this business model,” said Ms. Usoro. “Are these guys able to take care of the end of life?”

Yummy Plastics

“From Waste to Food: A Generator of Future Food” by Ting Lu and Stephen Techtmann, won the Merck 1 million prize.  It concerns an efficient, economical and versatile technology that converts wastes such as end-of-life plastics into edible foods. These foods contain all the required nutrition, are non-toxic, provide health benefits, and additionally allow for personalization needs. This technology promises to transform waste streams into nutritious food supplements, thus solving the two problems of increasing food scarcity and plastic waste simultaneously.

The core of the proposed technology is to harness synthetic microbial consortia – a combination of natural and rationally engineered microorganisms – in order to efficiently convert waste into food. The project will comprise four research goals: conversion from polyethylene terephthalate (PET) to protein powder (goal 1), augmentation of biosafety for food and for the environment (goal 2), introduction of nutritional and health-promoting contents (goal 3), and expansion of the technology to include additional plastics or other types of waste (goal 4). The proposed work will establish a transformative basis for food generation.

Green Con Artists and their Moneyed Followers

Green investing has grown so fast that there is a flood of money chasing a limited number of viable companies that produce renewable energy, electric cars and the like. Some money managers are stretching the definition of green in how they deploy investors’ funds. Now billions of dollars earmarked for sustainable investment are going to companies with questionable environmental credentials and, in some cases, huge business risks. They include a Chinese incinerator company, an animal-waste processor that recently settled a state lawsuit over its emissions and a self-driving-truck technology company.

One way to stretch the definition is to fund companies that supply products for the green economy, even if they harm the environment to do so. In 2020 an investment company professing a “strong commitment to sustainability” merged with the operator of an open-pit rare-earth mine in California at a $1.5 billion valuation. Although the mine has a history of environmental problems and has to bury low-level radioactive uranium waste, the company says it qualifies as green because rare earths are important for electric cars and because it doesn’t do as much harm as overseas rivals operating under looser regulations…

When it comes to green companies, “there just isn’t enough” to absorb investor demand…In response, MSCI has looked at other ways to rank companies for environmentally minded investors, for example ranking “the greenest within a dirty industry”….

Of all the industries seeking green money, deep-sea mining may be facing the harshest environmental headwinds. Biologists, oceanographers and the famous environmentalist David Attenborough have been calling for a yearslong halt of all deep-sea mining projects. A World Bank report warned of the risk of “irreversible damage to the environment and harm to the public” from seabed mining and urged caution. More than 300 deep-sea scientists released a statement today calling for a ban on all seabed mining until at least 2030. In late March 2021, Google, battery maker Samsung SDI Co., BMW AG and heavy truck maker Volvo Group announced that they wouldn’t buy metals from deep-sea mining.

[However the The Metals Company (TMC) claims that deep seabed mining is green].

Junk: the Engine of Green Growth

“Plastic waste is not just a global crisis that threatens economic recovery, climate, and nature. It is also an investment opportunity that can flip it from a scourge into an engine for economic development,” said Rob Kaplan, who founded Circulate Capital in 2017. Initially the firm sought to back companies in India and Southeast Asia, such as recycling or waste-sorting companies, that help reduce the amount of plastic waste that winds up in the ocean.

In 2019 it raised a $106 million debt and project finance fund, Circulate Capital Ocean Fund, backed by a handful of large multinational corporations that include Coca-Cola, Danone,  Procter & Gamble,  and Unilever…Circulate is one of a small but growing number of firms investing in companies that contribute to what they call the circular economy, a business model that seeks to eliminate waste that organizations produce, continuously reuse products and materials and regenerate natural systems.

An estimated 30 private-market funds, including private-equity, venture and debt strategies focused on the circular economy in the first half of 2020, up from just three in 2016….A number of large multinational corporations are funding these firms’ efforts as part of a broader push to reduce both the overall waste their own companies produce and the amount of virgin materials they use.

Unilever, which has backed funds managed by Circulate and New York-based Closed Loop Partners, aims to cut in half the amount of virgin plastic it uses by 2025 and plans to collect and process more plastic packaging than it sells. Coca-Cola, also a backer of Circulate’s Ocean fund, aims to make all of its global packaging recyclable by 2025 and to use at least 50% of recycled packaging material by 2030, among other goals.

Save Time and Money but Destroy Soil and Oceans

The images of swaths of garbage floating on the oceans’ surface have become a rallying call to address plastic pollution, but there is more to this challenge than meets the eye. While plastics and microplastics – items smaller than 5 mm – accumulate and impact marine environments, much of the problem is rooted in land contamination. Land-based plastic pollution, which often feeds into the oceans, is estimated to be at least four times higher than what is in the oceans, according to a study published in Global Change Biology. 

“Soil is the main source of microplastics reaching oceans through soil erosion and surface runoff,”  Plastics settle in soil through disposal in landfills, as well as through the use of plastic-sheets in agriculture or application of microplastic contaminated compost. “Direct disposal of plastics to ocean is relatively less pronounced compared to the transfer of microplastics from land. Microplastics, lighter than soil particles, such as sand, silt and clay, are easily lost to waterways,”…

“We contribute to plastic pollution through indiscriminate disposal of plastics in landfills and use of microbeads in cosmetics and microfibers in textiles. There are efforts to produce biodegradable plastics, which may provide some solution to plastic pollution, but bioplastic may not be the silver bullet to manage plastic pollution.” Commonly used biodegradable bioplastics “retain their mechanical integrity under natural conditions, potentially causing physical harm if they are ingested by marine or terrestrial animals.” “The fate of biodegradable bioplastics in natural and engineered environments could be potentially problematic. Methane is a product of biodegradation in anaerobic environments in landfills.” These bioplastics, furthermore, require high temperatures, controlled aeration and humidity to degrade completely.

Due to their small size, microplastics, especially nanoplastics resulting from the degradation of microplastic, can enter organisms’ internal organs, where they could potentially transfer contaminants attached to them. These can include persistent organic pollutants, like polychlorinated biphenyls (PCBs), as well as trace metals like mercury and lead. The plastics and pollutants that accumulate on or in them enter the food chain and can eventually be transferred to humans, causing growing food safety concerns.

The Joint FAO/IAEA Centre’s laboratories are equipped to research the presence of microplastics in food. “Techniques such as energy dispersive X-ray spectroscopy and infrared and Raman spectroscopy can be applied to screen for plastics in foods, enabling risk assessment and management,” said Andrew Cannavan, Head of the Joint Centre’s Food and Environmental Protection Section.

The Most Radioactive Sea on Earth and How to Save it

No other places in the world’s oceans have more radioactive and nuclear waste than the Kara Sea. The reactors from the submarines K-11, K-19, and K-140, plus the entire submarine K-27 and spent uranium fuel from one of the old reactors of the Lenin-icebreaker have to be lifted from the seafloor and secured. While mentality in Soviet times was «out of sight, out of mind», the Kara Sea seemed logical. Ice-covered most of the year, and no commercial activities. That is changing now with rapidly retreating sea ice, drilling for oil-, and gas and increased shipping.

The submarine reactors dumped in shallow bays east of the closed-off military archipelago of Novaya Zemlya… had experienced accidents and posed a radiation threat at the navy yards where people were working.  Dumping the reactors in shallow waters, someplace at only 50 meters, meant they could be lifted one day when technology allowed.

A worst-case scenario would be a failed lifting attempt, causing criticality in the uranium fuel, again triggering an explosion with following radiation contamination of Arctic waters.  

A Russian-Norwegian expedition to the K-27 submarine in Stepovogo bay in 2012 took samples for studying possible radioactive leakages. Now, the Bellona group, an environmental NGOs, calls  an expedition in 2021  to thoroughly study the strength of the hull and look for technical options on how to lift the heavy submarine and reactor compartments. A previous study report made for Rosatom and the European Commission roughly estimated the costs of lifting all six objects, bringing them safely to a yard for decommissioning, and securing the reactors for long-term storage.

The estimated price-tag for all six is €278 million, of which the K-159 in the Barents Sea is the most expensive with a cost of €57.5 million. Unlike the submarines and reactors that are dumped in relatively shallow waters in the Kara Sea, the K-159 is at about 200 meters depth, and thus will be more difficult to lift.

The Wild West Mentality of Companies Running the U.S. Oil and Gas Infrastructure — and Who Pays for It

The ransomware attack on Colonial Pipeline Co. in May 2021 has hit an industry that largely lacks federal cybersecurity oversight, leading to uneven digital defenses against such hacks.

The temporary shutdown of Colonial’s pipeline, the largest conduit for gasoline and diesel to the East Coast, follows warnings by U.S. officials in recent months of the danger of cyberattacks against privately held infrastructure. It also highlights the need for additional protections to help shield the oil-and-gas companies that power much of the country’s economic activity, cyber experts and lawmakers say. “The pipeline sector is a bit of the Wild West,” said John Cusimano, vice president of cybersecurity at aeSolutions, a consulting firm that works with energy companies and other industrial firms on cybersecurity. Mr. Cusimano called for rules similar to the U.S. Coast Guard’s 2020 regulations for the maritime sector that required companies operating ports and terminals to put together cybersecurity assessments and plans for incidents.

 More than two-thirds of executives at companies that transport or store oil and gas said their organizations are ready to respond to a breach, according to a 2020 survey by the law firm Jones Walker LLP. But many don’t take basic precautions such as encrypting data or conducting dry runs of attacks, said Andy Lee, who chairs the firm’s privacy and security team. “The overconfidence issue is a serious phenomenon,” Mr. Lee said.

Electric utilities are governed by rules enforced by the North American Electric Reliability Corp., a nonprofit that reviews companies’ security measures and has the power to impose million-dollar fines if they don’t meet standards. There is no such regulatory body enforcing standards for oil-and-gas companies, said Tobias Whitney, vice president of energy security solutions at Fortress Information Security. “There aren’t any million-dollar-a-day potential fines associated with oil-and-gas infrastructure at this point,” he said. “There’s no annual audit.”

How Air Pollution Infiltrates the Seas

A global effort to curb pollution from the heavy fuel oil burned by most big ships appears to be encouraging water pollution instead. A 2020 regulation aimed at cutting sulfur emissions from ship exhaust is prompting many owners to install scrubbing systems that capture pollutants in water and then dump some or all of the waste into the sea.

Some 4 300 scrubber-equipped ships are already releasing at least 10 gigatons of such wastewater each year, often in ports and sometimes near sensitive coral reefs…. The shipping industry says pollutants in the waste don’t exceed national and international limits, and that there’s no evidence of harm. But some researchers fear scrubber water, which includes toxic metals such as copper and carcinogenic compounds called polycyclic aromatic hydrocarbons, poses a rapidly growing threat, and they want to see such systems outlawed.

The emerging debate is the result of a 2020 regulation put into place by the International Maritime Organization (IMO), an arm of the United Nations that works with 174 member states to develop common rules for international shipping. By banning the use of sulfur-heavy fuel oil, the rule intended to reduce pollutants that contribute to acid rain and smog. IMO estimated the rule would slash sulfur emissions by 77% and prevent tens of thousands of premature deaths from air pollution in ports and coastal communities.

But cleaner fuel can cost up to 50% more than the sulfur-rich kind, and the rule allows ship owners to continue to burn the cheaper fuel if they install scrubbers. In 2015, fewer than 250 ships had scrubbers (often to comply with local regulations); last year, that number grew to more than 4300, according to industry figures.

A scrubber system sends exhaust through a meters-tall metal cylinder, where it is sprayed with seawater or freshwater, depending on the type, at rates comparable to gushing fire hydrants, to capture pollutants. In the most popular systems, called open loop scrubbers, seawater is discharged to the ocean after little or no treatment. Other systems retain sludge for disposal on land and release much smaller (but more concentrated) amounts while at sea….Researchers are particularly worried about discharges in areas that IMO has designated as ecologically sensitive. The Great Barrier Reef, for example, receives about 32 million tons of scrubber effluent per year because it’s near a major shipping route for coal. Ships also release scrubber water around the Galápagos Islands….

Ports see substantial discharges, too. Cruise ships dominate those releases, contributing some 96% of discharges in seven of the 10 most discharge-rich ports. Cruise ships typically need to burn fuel in port to continue to operate their casinos, heated pools, air conditioning, and other amenities. Most ports have shallow water, so pollutants are less diluted and can accumulate more rapidly….

Researchers, who are participating in a €7.5 million European effort to study shipping pollution called EMERGE, would like to study how scrubber water affects fish larvae.

But shippers have become hesitant to share samples and data with scientists. “We’re reluctant to give it to organizations which we know have already an established agenda,” says Mike Kaczmarek, chairman of the Clean Shipping Alliance 2020

The ultimate solution is to require ships to use the cleanest fuel, called marine gas oil. In the meantime, 16 countries as well as some localities have banned the most common scrubbers.

A Gun to their Head: the Exclusive Vaccine Club

International tensions over access to Covid-19 vaccines have intensified as supply hiccups disrupt mass rollouts of shots. But trade experts warn that restrictions on vaccine exports risk making a bad situation worse. That’s because the world’s major vaccine producers rely on each other for the essential ingredients to manufacture vaccines through a web of cross-border supply chains in complex chemicals, fatty acids and glass vials. If governments restrict vaccine exports, they risk retaliation from other members of this exclusive club of vaccine makers, who could withhold vital supplies, squeezing production just when it is needed most.

These supply chains stretch across the world, drawing in producers of basic chemicals that provide critical ingredients as well as the pharmaceutical powerhouses that make the vaccines. The  U.S. , the  European Union  and  China  are among a handful of territories that produce vaccine ingredients and final vaccines for the entire world. More than half of global vaccines and of key vaccine ingredients come from the  U.S.  and  EU . These 12 countries and the EU make up the “Vaccine Club”—producers that make both the key ingredients as well as final vaccines

The members of the vaccine club, though, source on average 88.3% of the imported ingredients used in vaccine production from other club members, according to economists led by Simon Evenett, professor of international trade and economic development at the University of St. Gallen in Switzerland, who have mapped trade flows between the world’s major vaccine producers. Limiting vaccine exports to another major producer would therefore risk retaliatory action that could undermine production, threatening the mass vaccination drives that are the key to ending the pandemic, Prof. Evenett said. “Everyone has a gun to each other’s heads,” he said.

Begging for a Vaccine: the other COVID crisis

On April 16, 2021  Adar Poonawalla, head of the world’s biggest vaccine-maker, the Serum Institute of India (SII), begged President Joe Biden, in a tweet, to ‘lift the embargo of raw material exports out of the us.’… because it would affect the manufacturing of vaccines: AstraZeneca’s, of which SII makes 100m doses a month, and Novavax’s, of which it expects to make 60m-70m doses a month.

That was shortly after the Biden administration announced, on February 5, 2021, plans to use the Defense Production Act (DPA)—a law dating from the 1950s that grants the president broad industrial-mobilization powers—to bolster US vaccine-making. This legislation…has helped American pharmaceutical companies to secure a variety of special materials and equipment, including plastic tubing, raw goods, filters and even paper, that are needed for vaccine production. But firms which export such products point out that the DPA  hinders their ability to sell them abroad. They must seek permission before exporting these goods. That requires time and paperwork. And if the government decides it needs the goods in question to remain in the country, the firms concerned may be barred from exporting them at all… 

To be used in vaccine manufacturing, products have to be approved by regulators. So finding substitutes quickly can be impossible. SII is not alone in its concern. On March 24, 2021  Micheal Martin, Ireland’s prime minister, warned that export bans (and not just from America) would harm global vaccine production. He noted that the Pfizer vaccine involves 280 components from 86 suppliers in 19 countries. Indeed, American export controls particularly harm European vaccine companies, which need special bags from America in which to make their products. At a vaccine supply-chain meeting in March, one such firm complained of 66-week delivery times for the supply of these bags.

The Plastics Revolution: A Century Later

Businesses pay a fee to Tontoton,  a company established in 2019,  for every ton of plastic that they generate. Tontoton then uses the money to employ scavengers, who retrieve an equal weight of plastic garbage in Vietnam — the world’s No. 4 source of ocean debris…Tontoton said it has the only such program in Vietnam, while Plastic Bank runs a similar one in Indonesia and the Philippines, and the Plastic Collective covers Malaysia, Thailand, and Cambodia…Tontoton targets the worst ocean-bound rubbish, called orphan plastic because it cannot be recycled. Trash pickers find the single-use plastic along the cyan waters hugging Vietnam’s Phu Quoc and Hon Son islands. Their goal is to collect 5,000 tons a year and send it to INSEE, part of Siam City Cement, to be burned for energy….

These cleanup programs have sprung up globally as doubts emerge about recycling, which used to seem like a win-win idea because consumers could keep consuming and the environment could stay pristine. But instead, for decades, the public believed its plastic was being recycled, only to find that 91% of it was not, according to a study in the peer-reviewed journal Science Advances, assessing all plastic from 1950-2015.

Vietnam is a focus of cleanup campaigns because it’s among the top five countries sending litter to sea, along with China, Indonesia, the Philippines, and Thailand…These Asian countries earned this marker because they import so much waste for processing from the rest of the world.

Tontoton says clients sign a letter committing to multiple strategies beyond offsets, including plastic substitutes and reduction. The company helps them offset or “neutralize” plastic already used, but this isn’t a “getaway car” to escape broader responsibility. “Plastic neutralization cannot solve the problem by itself.”

Better than Gods: Can We Master the Climate?

Given the urgency of the risks posed by climate change, the U.S. should pursue a research program for solar geoengineering — in coordination with other nations, subject to governance, and alongside a robust portfolio of climate mitigation and adaptation policies, says a 2021 report from the National Academies of Sciences, Engineering, and Medicine. The report emphasizes that solar geoengineering is not a substitute for reducing greenhouse gas emissions.
 
Solar geoengineering refers to strategies designed to cool Earth either by adding small reflective particles to the upper atmosphere, by increasing reflective cloud cover in the lower atmosphere, or by thinning high-altitude clouds that can absorb heat. While such strategies have the potential to reduce global temperatures and thereby ameliorate some of the risks posed by climate change, they could also introduce an array of unknown or negative consequences

Scientific understanding of many aspects of solar geoengineering technologies remains limited, including how they could affect weather extremes, agriculture, natural ecosystems, or human health. There currently is no coordinated national effort for solar geoengineering research. The report recommends a comprehensive plan for governing solar geoengineering research, designed to ensure it moves forward in a socially responsible manner. Researchers should follow a code of conduct, for example, and research should be catalogued in a public registry, be subject to regular program assessment and review, and allow for public engagement.

Deliberate outdoor experiments that involve releasing substances into the atmosphere should be considered only when they can provide critical observations that cannot be provided by laboratory study, modeling, or experiments of opportunity — such as volcanic eruptions. Outdoor experiments should be subject to appropriate governance including permitting and impact assessments, says the report…The report says the U.S. Global Change Research Program (USGCRP) should lead the effort to establish and coordinate a solar geoengineering research program across federal agencies and scientific disciplines, with funding in the range of $100 million-$200 million over the first five years. USGCRP would enable oversight and governance of research activities, including ensuring peer review, coordinating budget proposals and requests, periodically assessing progress, and defining program goals. Funding should be set aside specifically for implementation of governance and public engagement efforts.

Nuking Tahiti: the Moruroa Files

From 1966 to 1974, France blew up 41 nuclear weapons in above-ground tests in French Polynesia, the collection of 118 islands and atolls that is part of France. The French government has long contended that the testing was done safely. But a new analysis of hundreds of documents declassified in 2013 suggests the tests exposed 90% of the 125,000 people living in French Polynesia to radioactive fallout—roughly 10

The findings come from a 2-year collaboration, dubbed the Moruroa Files, between Disclose, a French nonprofit that supports investigative journalism; Interprt, a collective of researchers, architects, and spatial designers affiliated with the Norwegian University of Science and Technology who focus on environmental issues; and the Science & Global Security program at Princeton. The findings were presented on 9 March on the project’s website, in a book, and in a technical paper posted to the arXiv preprint server.

The abandoned testing facility at the Moruroa Atoll. The atoll is at the risk of collapsing due to nuclear blasts

Declassified documents suggest actual exposures were between two and 20 times higher than France’s Atomic Energy Commission (CEA) estimates… Reasons for the discrepancies vary from test to test, he says. For example, CEA acknowledged that the first test, dubbed Aldébaran, exposed residents of the Gambier Islands to relatively high levels of fallout. But actual exposures were likely higher still… Although CEA noted that contaminated rainwater fell on the island, he says, it failed to consider that many residents likely drank the contaminated water, collected in household cisterns, for days.

Most important, the documents suggest a single test in 1974, called Centaure, exposed the entire population of Tahiti—87,500 people at the time—to fallout. French authorities set off a relatively tiny atom bomb with an explosive yield equal to 4 kilotons of TNT, and weather forecasts predicted that winds should carry fallout to the north. Instead, the wind blew to the west, carrying the plume directly over Tahiti. A new simulation based on data in the documents shows how the plume of radiation wafted over the island. CEA estimated that people on the island received a dose of about 0.6 mSv.  However, Phillipe and colleagues argue that CEA underestimated the total amount of radiation that accumulated on the ground over several days, didn’t account for radiation lingering in vegetables consumed later…

The new analysis moves the vast majority of French Polynesians past the exposure threshold to qualify for compensation. Philippe and Schoenberger would like to see France do away with the exposure standard and compensate anyone who lived through the tests and developed a qualifying cancer. “Our hope is to demonstrate that this kind of threshold can be prejudicial to claimants just because of the difficulties of proving exposure,” Schoenberger says.

Philippe estimates that, assuming a cancer rate of 0.2% per year, roughly 10,000 cancer patients or their families would qualify retroactively and that compensating them would cost about €700 million. Future cancers would cost about €24 million per year, he estimates. However, Hughes says it remains to be seen whether the French government will even acknowledge the analysis. “My fear is that they will simply ignore it,” Hughes says.

The declassified documents also show the French government routinely failed to warn Polynesians about the radiation risks, Philippe says. In the Centaure test, authorities could have warned Tahitians about the approaching fallout 2 days in advance, but did not. Ironically, Philippe notes, the United States, the Soviet Union, and other countries were monitoring the tests remotely. “Everybody knew what was going on,” he says, “except the Polynesians.”

Wild West: Mercury Pollution in the Amazon Rainforest

Munduruku Indigenous people in the Tapajós basin – an epicenter of illegal gold mining in the Amazon rainforest – in southwestern Pará state have reported increasing encroachments upon their lands by armed “wildcat” miners known as “garimpeiros” since March 14, 2021. The Federal Prosecutor’s Office has warned of a potential for violence between local residents and the miners and urged the deployment of the federal police and other authorities to remove the trespassers. But the government has yet to act. The tension has escalated in recent weeks after a group of miners brought equipment to the area.

Illegal mining causes significant deforestation in the Brazilian Amazon and has been linked to dangerous levels of mercury poisoning, from mercury widely used to process the gold, in several Munduruku communities along the Tapajós basin. Indigenous people also fear that miners could spread the Covid-19 virus in their communities.

In a public statement on March 16, 2021 the Federal Prosecutor’s Office reported that a helicopter appeared to have escorted the miners and their equipment, suggesting the invasion is “an orchestrated action” by an organized crime group. The office also reported that the miners may be coordinating the invasion with a “small group” of Indigenous people who support the mining. Members of Munduruku communities who oppose the mining and have reported the invasions to the authorities say they have faced threats and intimidation. On March 19, 2021 armed men reportedly prevented a group of Munduruku Indigenous people from disembarking from their boats in an area within their territory. On March 25, 2021 in the Jacareacanga municipality, miners and their supporters forced their way into a building that houses the Wakoborun Women’s Association and other community organizations that have opposed the mining. The attackers destroyed furniture and equipment and set fire to documents, Indigenous leaders reported…

President Bolsonaro has signaled his aversion to protecting Indigenous lands. As a candidate, he vowed not to designate “one more centimeter” of land as Indigenous territory. His administration has halted the demarcation of Indigenous territories – there are 237 pending requests – leaving Indigenous communities even more vulnerable to encroachments, deforestation, and violence. The Munduruku territory is already demarcated. In 2020, Bolsonaro introduced a draft bill in Congress to allow mining and other commercial activities in Indigenous territories. The bill is pending in Congress and is listed as one of Bolsonaro’s priorities.

It’s Easy: How to Make a Radioactive Dirty Bomb

A truck carrying highly radioactive materials has been stolen by armed criminals in central Mexico the Independent reported on April 12, 2012. The Mexican government is now warning that anybody who comes in close contact with its deadly payload could be risking their lives. The individuals got away with an industrial inspection equipment truck during an armed heist on April 11, 2021 in the town of Teoloyucan. Included in the bounty is a QSA Delta 800 gamma ray projector that holds radioactive iridium-192, selenium-75 and ytterbium-169 isotopes — a highly unusual bounty for any hijacker.

It’s still unclear why they targeted the truck in question, but during a previous robbery involving radioactive waste, Mexican authorities feared the ingredients may be used to build a dirty bomb. Contact with the contents of the truck, authorities emphasized, can be fatal. “At 10am today, there was a robbery of radiographic equipment reported,” reads a warning issued by the National Commission for Nuclear Security and Safeguarding, as quoted by the Independent. “If the radioactive material is extracted from the container, is moved, or makes direct contact with any persons handling it, permanent injury can occur in minutes.” “In case of making direct contact with the source over the course of hours or days, the effects can prove fatal,” the warning reads. Even just being 30 meters away could cause radiation poisoning, according to the Commission.

Members of the Commission for National Civil Protection (CNPC) have been dispatched across the central region of Mexico. Authorities have not ruled out the possibility that the truck may now be in Mexico City….This is not the first time radioactive material has been stolen in Mexico.

Facing the Unprecedented: Nuclear Waste Burial in China

China is building a massive underground laboratory to research disposal technologies for high-level radioactive waste, the most dangerous byproduct of nuclear technology and applications. This is meant to pave the way for a repository that can handle the disposal of at least a century’s worth of such materials for tens of thousands of years, the lab’s chief designer told China Daily in an exclusive interview.

The lab will be situated in granite up to 560 meters below ground in the Beishan region of Gansu province, said Wang Ju, vice-president of the Beijing Research Institute of Uranium Geology. The underground lab was listed as one of China’s major scientific construction projects in the 13th Five-Year Plan (2016-20).

Its surface facilities will cover 247 hectares, with 2.39 hectares of gross floor space. The underground complex will have a total structural volume of 514,200 square cubic meters, along with 13.4 kilometers of tunnels, he added. The lab is estimated to cost over 2.72 billion yuan ($422 million) and take seven years to build. It is designed to operate for 50 years, and if its research proves successful and the site is suitable, a long-term underground repository for high-level waste will be built near the lab by 2050

According to the 14th Five-Year Plan (2021-25), China seeks to cut carbon emissions by optimizing its energy consumption structure and raising its proportion of nonfossil energy. This includes building a new generation of coastal nuclear plants,… small-scale reactors and offshore floating reactors.. As of 2020, China had 49 nuclear reactors in operation, making it the world’s third-largest nuclear energy producer, behind the United States and France. There are 16 nuclear reactors in construction in China, the most in the world, according to the World Nuclear Association.

The Fukushima Nuclear Meltdown: Ten Years — and Counting

A resolution to the crisis at the Fukushima Daiichi nuclear power plant remains a distant goal a decade after three of its reactors melted down. The most challenging part of the cleanup—removing molten nuclear fuel from each reactor—has yet to begin because of high radiation inside the reactor buildings, putting the targeted decommissioning of the plant by 2051 into doubt.

More than 80% of the Japanese public doesn’t feel significant progress is being made and is concerned about further accidents because of recent events. On Feb. 13, 2021 a large earthquake centered near Fukushima, an aftershock of the one 10 years ago, caused water to slosh out of a tank containing spent fuel rods, which must be kept submerged to avoid overheating. A week later, a fish caught off the coast of Fukushima was found to contain 10 times the allowed level of radioactive cesium…This incident shows how risks from the plant continue to weigh on those who live and work nearby. 

“We are still struggling with harmful rumors from the nuclear plant accident,” said Tadaaki Sawada, a spokesman for the federation of Fukushima fishery cooperatives. “How many more years will it continue?”…By several measures, the worst nuclear disaster since the Chernobyl accident in 1986 has been contained. Only around 2% of Fukushima prefecture, or state, is still a no-go area, down from 12% immediately after the disaster. An extensive decontamination process removed topsoil from areas around the plant. Still, thousands of people remain forced out of towns closest to the plant.

In 2020, plant operator Tokyo Electric Power Co., known as Tepco, and the government were close to a decision to start releasing into the sea over a million cubic meters of water from the plant, but plans were suspended amid opposition from local fishermen and concerns raised by neighboring countries. Contaminated rain and groundwater is stored in large tanks that dominate one side of the plant site. Once treated to remove most radioactive elements, the water still contains tritium, a form of hydrogen that emits a weak form of radiation. Tritium is regularly released into the sea and air from nuclear plants around the world after dilution.

Inspectors from the International Atomic Energy Agency visited the Fukushima plant in 2020 and said disposal of the treated water into the sea would be in line with international practice. “A decision on the disposition path should be taken urgently” to keep the overall decommissioning on track, the IAEA said.

The most challenging part of the cleanup—removing molten nuclear fuel from each reactor—has yet to begin…Tepco has yet to get a clear picture of the location of molten fuel in the reactors because the levels of radiation are damaging even to robots…Gov. Uchibori said that gaining an accurate grasp of the molten-fuel situation was critical to making headway. “If you look at the entire process, right now we are still around the starting point of decommissioning,” he said.

The Toxic Shadow of Abandoned Oil Infrastructure

Wearing blue hard hats, white hazmat suits and respirator masks, workers carted away bags of debris on a recent morning from a sprawling and now-defunct oil refinery once operated by Philadelphia Energy Solutions (PES). Other laborers ripped asbestos from the guts of an old boiler house, part of a massive demolition and redevelopment of the plant, which closed in 2019 after a series of explosions at the facility.

Plans call for the nearly 1,400-acre site to be transformed into a new commercial hub with warehousing and offices. All it will take is a decade, hundreds of millions of dollars, and confronting 150 years’ worth of industrial pollution, including buried rail cars and a poisonous stew of waste fuels poured onto the ground. A U.S. refinery cleanup of this size and scope has no known precedent, remediation experts said. It’s a glimpse of what lies ahead if the United States hopes to wean itself off fossil fuels and clean up the toxic legacy of oil, gas and coal.

President Joe Biden wants to bring the United States to net-zero greenhouse gas emissions by 2050 to fight climate change through a shift to clean-energy technologies, while reducing pollution in low-income and minority neighborhoods near industrial facilities. It’s a transition fraught with challenges. Among the biggest is what to do with the detritus left behind. The old PES plant is just one of approximately 135 oil refineries nationwide, to say nothing of the country’s countless gas stations, pipelines, storage hubs, drill pads and other graying energy infrastructure.

In Philadelphia, a private-sector company is taking the lead. Hilco Redevelopment Partners, a real estate firm that specializes in renovating old industrial properties, bought the PES refinery out of bankruptcy for $225.5 million in June…The full extent of the pollution won’t be understood for years. Also uncertain is the ability of the refinery’s previous owners to pay their share of the cleanup. The facility has had multiple owners over its lifetime and responsibility has been divided between them through business agreements and legal settlements.
Oil refining at the Philadelphia site began in 1870, 100 years before the creation of the U.S. Environmental Protection Agency (EPA). Gasoline, once a worthless byproduct of heating oil, was routinely dumped by the refinery into the soil, according to historians and researchers. Leaks and accidents spewed more toxins. The June 2019 blasts alone released 676,000 pounds of hydrocarbons, PES said at the time. The Philadelphia site is not unique. About half of America’s 450,000 polluted former industrial and commercial sites are contaminated with petroleum, according to the EPA.

Cleanup in Philadelphia will be painstaking. After asbestos abatement comes the demolition and removal of 3,000 tanks and vessels, along with more than 100 buildings and other infrastructure, the company said. Then comes the ground itself. Hilco’s Perez said dirt quality varies widely on the site and will have to be handled differently depending on contamination levels. Clearing toxins like lead must be done with chemical rinses or other technologies…The site also has polluted groundwater and giant benzene pools lurking underneath, according to environmental reports Sunoco filed over the years with the federal and state governments.

How the Global Trade in Plastics Spills Over the Oceans

Low-value or “residual” plastics – those left over after more valuable plastic is recovered for recycling – are most likely to end up as pollution. So how does this happen? In Southeast Asia, often only registered recyclers are allowed to import plastic waste. But due to high volumes, registered recyclers typically on-sell plastic bales to informal processors…When plastic types were considered low value, informal processors frequently dumped them at uncontrolled landfills or into waterways.

Plastics stockpiled outdoors can be blown into the environment, including the ocean. Burning the plastic releases toxic smoke, causing harm to human health and the environment. When informal processing facilities wash plastics, small pieces end up in wastewater, which is discharged directly into waterways, and ultimately, the ocean.

The price of many recycled plastics has crashed in recent years due to oversupply, import restrictions and falling oil prices, (amplified by the COVID-19 pandemic). However clean bales of (polyethylene terephthalate) PET and (high-density polyethylene) HDPE are still in demand. In Australia, material recovery facilities currently sort PET and HDPE into separate bales. But small contaminants of other materials (such as caps and plastic labels) remain, making it harder to recycle into high quality new products. Before the price of many recycled plastics dropped, Australia baled and traded all other resin types together as “mixed plastics”. But the price for mixed plastics has fallen to zero and they’re now largely stockpiled or landfilled in Australia.

Beyond Deforestation–Toxic Waste Pollution at the Amazon Rainforest

Maria do Socorro explains in graphic detail the spate of ailments affecting newborns in her remote community in the Amazon: her grandson died after being born with his intestines outside his body, while others were missing organs or had undeveloped bones.  For the 56-year-old community leader, there is little doubt about the cause of these illnesses. She said the rainforest town had for years suffered from toxic waste pollution from the local operations of Norwegian aluminum producer Norsk Hydro.

Long a simmering environmental scandal in Brazil, the allegations were brought on to the international stage in February 2021 when Socorro’s community sued the Norwegian giant in a Dutch court, seeking damages for claims that “the incorrect disposal of toxic waste” from operations in the area had caused a variety of health ailments, polluted the rainforest and destroyed economic opportunities.

“If business can be global, why can’t justice? These companies have businesses everywhere, but then when they do something wrong they want to smother the possibility of people getting compensation,” said Pedro Martins, partner at law firm PGMBM, which is representing 40,000 alleged victims bringing the suit against Norsk Hydro…

Through local entities, Norsk Hydro runs three facilities — a bauxite mine, a refinery and a smelter — in Pará, a vast Amazonian state that is a flashpoint for illegal deforestation, gold mining and land-grabbing.  The company…denied that in 2018 pollutants from its facilities spilled over during heavy rains and polluted nearby rivers and earth….

Locals say bauxite, lead and aluminium pollution have turned the region’s rivers red. A study from the Evandro Chagas Institute, a Brazilian public health body, found in 2018 that the region’s waters were so polluted with industrial waste from the Norsk Hydro facilities that they “cannot be used for recreation, fishing, or human consumption”.

“I invite these Norwegians to come and bathe in our waters. I challenge them. They have good water there in Norway. Our wealth just goes there,” said Socorro, who heads Cainquiama, a group representing mainly indigenous people and quilombolas — the descendants of runaway slaves. Nearly all of the claimants in the suit have complained about chronic pain, hair loss and skin conditions. The suit also contains claims in relation to birth defects, such as those that have affected Socorro’s grandson, who was born with gastroschisis — a hole in the abdominal wall.

The case is a sensitive one for Norwegian investors and the government, which owns a 34 per cent stake in Norsk Hydro. Oslo has long attempted to hold Brasília to account for the environmental destruction of the Amazon, even publishing its own data on deforestation in the world’s largest rainforest.

How Soil Can Fight Pollution

Soil biodiversity is essential for most of the ecosystem services and functions that soils
provide and perform. Soil microbes (i.e., bacteria, fungi) and microfauna (i.e., protozoa
and nematodes) transform organic and inorganic compounds into available forms. These transformations are critical for nutrient cycling and availability, for plants, and other species growth, for cycling of soil organic matter and carbon sequestration, and for the filtration, degradation, and immobilization of contaminants in water and soil.

An important part of the food web is represented by mesofauna, such as springtails and mites, which accelerate litter decomposition and enhance nutrient cycling and availability (especially nitrogen), and predators of smaller soil organisms.

Soil macro, and megafauna such as earthworms, ants, termites, and some mammals act as ecosystem engineers that modify soil porosity, water and gas transport, and bind soil particles together into stable aggregates that hold the soil in place and thus reduce erosion.

Soil biodiversity can mitigate threats to ecosystem services, for instance by acting as a powerful tool in bioremediation of contaminated soils. Biostimulation and bioaugmentation are environmentally sound strategies that contribute to the filtration, degradation, and immobilization of target contaminants. Furthermore, the integral use of organisms such as microbes (bioaugmentation), plants (phytoremediation) and earthworms (vermiremediation) as a bioremediation strategy in hydrocarbon-contaminated soils has proven to be a viable alternative for increasing hydrocarbon removal. On the other hand, soil macrofauna, such as earthworms, termites, and ants, play an important role in improving soil structure and aggregation, which can improve resistance to soil erosion caused by wind and water.

Natural Capital and Human Well-Being

What is the contribution of nature to the economy?… The breathable air, drinkable water and tolerable temperatures that allow humans to do everything they do, and the complex ecosystems that maintain them, tend to be taken for granted. Professor Dasgupta’s review on the Economics of Biodiversity does not seek to play on the heartstrings with tales of starving polar bears. Rather, it makes the hard-headed case that services provided by nature are an indispensable input to economic activity. Some of these services are relatively easy to discern: fish stocks, say, in the open ocean. Others are far less visible: such as the complex ecosystems within soil that recycle nutrients, purify water and absorb atmospheric carbon. These are unfamiliar topics for economists, so the review seeks to provide a “grammar” through which they can be analysed.

The report features its own illustrative production function, which includes nature. The environment appears once as a source of flows of extractable resources (like fish or timber). But it also shows up more broadly as a stock of “natural” capital. The inclusion of natural capital enables an analysis of the sustainability of current rates of economic growth. As people produce GDP, they extract resources from nature and dump waste back into it. If this extraction and dumping exceeds nature’s capacity to repair itself, the stock of natural capital shrinks and with it the flow of valuable environmental services. Between 1992 and 2014, according to a report published by the UN, the value of produced capital (such as machines and buildings) roughly doubled and that of human capital (workers and their skills) rose by 13%, while the estimated value of natural capital declined by nearly 40%. The demands humans currently place on nature, in terms of resource extraction and the dumping of harmful waste, are roughly equivalent to the sustainable output of 1.6 Earths (of which, alas, there is only the one)…Indeed, Professor Dasgupta argues that economists should acknowledge that there are in fact limits to growth. As the efficiency with which we make use of Earth’s finite bounty is bounded (by the laws of physics), there is necessarily some maximum sustainable level of GDP…

Professor Dasgupta hints at this problem by appealing to the “sacredness” of nature, in addition to his mathematical models and analytical arguments.

At Gunpoint in Congo: Is Coltan Worse than Oil?

Tantalum, a metal used in smartphone and laptop batteries, is extracted from coltan ore. In 2019 40% of the world’s coltan was produced in the Democratic Republic of Congo, according to official data. More was sneaked into Rwanda and exported from there. Locals dig for the ore by hand in Congo’s eastern provinces, where more than 100 armed groups hide in the bush. Some mines are run by warlords who work with rogue members of the Congolese army to smuggle the coltan out.

When demand for electronics soared in the early 2000s, coltan went from being an obscure, semi-valuable ore to one of the world’s most sought-after minerals. Rebels fought over mines and hunted for new deposits. Soldiers forced locals to dig for it at gunpoint. Foreign money poured into Congo. Armed groups multiplied, eager for a share.

Then, in 2010, a clause in America’s Dodd-Frank Act forced American firms to audit their supply chains. The aim was to ensure they were not using minerals such as coltan, gold and tin that were funding Congo’s protracted war. For six months mines in eastern Congo were closed, as the authorities grappled with the new rules. Even when they reopened, big companies, such as Intel and Apple, shied away from Congo’s coltan, fearing a bad press.

The “Obama law”, as the Congolese nickname Dodd-Frank, did reduce cash flows to armed groups. But it also put thousands of innocent people out of work. A scheme to trace supply chains known as ITSCI run by the International Tin Association based in London and an American charity, Pact, helped bring tentative buyers back to Congo.  ITSCI staff turn up at mining sites to see if armed men are hanging about, pocketing profits. They check that no children are working in the pits. If a mine is considered safe and conflict-free, government agents at the sites put tags onto the sacks of minerals. However, some unscrupulous agents sell tags on the black market, to stick on coltan from other mines. “The agents are our brothers,” Martin says. It is hard to police such a violent, hilly region with so few roads. Mines are reached by foot or motorbike along winding, muddy paths.

For a long time those who preferred to export their coltan legally had to work with itsci, which held the only key to the international market. Miners groaned that itsci charged too much: roughly 5% of the value of tagged coltan. When another scheme called “Better Sourcing” emerged, Congo’s biggest coltan exporter, Société Minière de Bisunzu, signed up to it instead.

How to Find the True Cost of Water

At current rates of consumption, the demand for water worldwide will be 40% greater than its supply by 2030, according to the UN. Portfolio managers are realizing that physical, reputational and regulatory water risk could hurt their investments, particularly in thirsty industries such as food, mining, textiles and utilities.

One worry is that shocks to supply could drown or dry out a company’s assets. In recent years Coca-Cola has been forced to close plants in India because of drought. In 2019 floods in America’s Midwest caused disruptions at the facilities of two food giants, Cargill and Tyson Foods. A survey by CDP, a non-profit firm, found that 783 big listed companies had faced a total of $40bn of water-related losses in 2018.

Another concern is that the price a company pays for water could rocket. The market price of water does not reflect the environmental and social costs of using it. Government subsidies also mean that companies often do not pay for its true cost. As aquifers are depleted, though, subsidies could become more costly and unpopular, forcing governments to retract them. S&P Global Trucost, a data provider, reckons that if Fortune 500 companies paid the true cost of water, based on estimates of scarcity, rather than current prices, their profit margins would shrink by a tenth. Margins for food, drink and tobacco firms would fall by three-quarters.

Disclosures of water risk are even patchier than those of greenhouse-gas emissions…Established names like Bloomberg and S&P Global are plugging the gap, as are startups. The result is that investors can approach management armed with data rather than questions. “We are getting rid of the black box that companies hide in.” 

Ceres, a non-profit firm, scores businesses on everything from direct water management to risks in the supply chain. Those seeking more detail can use visual tools, such as Bloomberg’s “maps” function, which plots a company’s facilities over a heat map based on water stress. (California is the same color as swathes of sub-Saharan Africa; far-eastern Russia looks a lot like western Europe.) Firms like Aquantix go further, and try to predict the financial cost of water risk.

The accuracy of such forecasts is not yet proven. For Andrew Mason of Aberdeen Standard Investments, though, they are still useful. They show companies that investors care about water risk and encourage them to share data. “This is where carbon was ten or 15 years ago,” he says.

The New Lepers: Oil in Ecuador and Arctic Drilling

Some of Europe’s largest banks are phasing out trading services for the export of oil from the Ecuadorean Amazon, a move that reflects the growing focus of global banks on climate change and their shift away from increasingly risky fossil fuels.

On January 25, 2021, Switzerland’s Credit Suisse Group AG and Holland’s ING said that they were excluding new transactions related to exports of Ecuador’s Amazonian oil from their trading activities, citing climate change and concerns for the Amazon rainforest and its Indigenous people. France’s BNP Paribas SA, the largest bank in the eurozone and one of the region’s trading powerhouses, said in December 2020 that it would immediately exclude from its trading activities the seaborne exports of oil from the Esmeraldas region in Ecuador under its latest environmental finance policies.

Ecuador isn’t one of the world’s top oil producers, but petroleum exports are a key contributor to the country’s economy. Petroecuador, the nation’s state-owned oil company, didn’t respond to requests for comment.  The banks’ flight from Amazonian crude follows last year’s crash in oil prices and growing fears of so-called stranded assets, which are fossil fuels that lose value due to the world’s transition to cleaner forms of energy…

Banks are also facing calls from environmentalists and Indigenous peoples to limit their involvement in fossil fuels. In Ecuador, a campaign by activists and Indigenous people spurred ING and Credit Suisse to reduce their exposure to the Amazonian oil trade. The nonprofits Stand.earth and Amazon Watch published a report in 2020 that called out banks—including ING, Credit Suisse and BNP Paribas—for their financing of Amazonian crude…

Banks and insurers are also cutting ties with Arctic oil drilling. This month, Axis Capital Holdings joined fellow insurers AXA and Swiss Re in pledging not to underwrite any new oil-and-gas drilling in the Arctic Wildlife Refuge in Alaska.  The six biggest U.S. banks— Citigroup Inc., Bank of America Corp. , Goldman Sachs Group Inc., JPMorgan Chase & Co., Morgan Stanley and Wells Fargo & Co.—have also said they would end funding for new drilling and exploration projects in the Arctic.

The Struggle of Managing Dis-Used Nuclear Sources

Two disused radioactive sources, previously employed in cancer treatment, are now in safe and secure storage in the Republic of the Congo, following successful transport and increased security at their temporary storage facility, with the support of the IAEA. The sources no longer emit enough radioactivity to be useful for radiotherapy but are still radioactive and therefore need to be controlled and managed safely and securely. They are expected to be exported outside the country in 2022.

“It took time to understand the risks posed by the disused radiotherapy sources stored for so long in our country…,” said Martin Parfait Aimé Coussoud-Mavoungou, Minister for Scientific Research and Technological Innovation.

Around the world, radioactive material is routinely used to diagnose and treat diseases… This material is typically managed safely and securely while in use; however, when it reaches the end of its useful lifespan, the risk of abandonment, loss or malicious acts grows. 

In 2010, the University Hospital of Brazzaville received a new cobalt 60 (Co-60) sealed source for the hospital’s teletherapy machine, replacing its original source, which was no longer able to deliver effective treatment. The disused sealed source was then packaged and shipped by boat to the supplier. However, the delivery of the package was blocked in transit due to problems with the shipping documents and was returned to the Republic of the Congo. Since 2010, the Co-60 source has been stored at the Autonomous Port of Pointe Noire, one of the most important commercial harbors in Central Africa…

“The August 2020 explosion that occurred in Beirut Harbor reminded the Congolese Authorities of the risks to unmanaged or unregulated material, particularly in national ports and harbors,” said Coussoud-Mavoungou. Congolese decision-makers agreed that the disused source had to urgently leave the Autonomous Port of Pointe Noire.

Following a comprehensive planning and preparation phase, a transport security plan was finalized on location in November 2020, with the support of IAEA experts. They designed a security system for the package and conducted a pre-shipment verification and simulation. At the same time, 45 participants were trained from the five government Ministries involved in the transport by road of the source in Pointe Noire.

Assigning Responsibility for Oil Leaks: Shell’s Deep Pockets

Royal Dutch Shell’s  Nigerian subsidiary has been ordered on January 29, 2021 by a Dutch court to pay compensation for oil spills in two villages in Nigeria…The case was first lodged in 2008 by four Nigerian farmers and Friends of the Earth Netherlands. They had accused Shell and its Nigerian subsidiary of polluting fields and fish ponds through pipe leaks in the villages of Oruma and Goi.

The Court of Appeal in the Hague, where Shell has its headquarters, also ordered the company to install equipment to safeguard against future pipeline leaks. The amount of compensation payable related to the leaks, which occurred between 2004 and 2007, is yet to be determined by the court.  The case establishes a duty of care for the parent company to play a role in the pollution abroad, in this case by having the duty to make sure there is a leak-detection system…

Shell argued that the leaks were caused by sabotage…

In recent years there have been several cases in U.K. courts related to whether claimants can take matters to a parent company’s jurisdiction. In 2019, the U.K. Supreme Court ruled that a case concerning pollution brought by a Zambian community against Vedanta, an Indian copper-mining company previously listed in the U.K., could be heard by English courts. “It established that a parent company can be liable for the actions of the subsidiary depending on the facts,” said Martyn Day, partner at law firm Leigh Day, which represented the Zambians.

The January 2021 case isn’t the first legal action Shell has faced related to pollution in Nigeria. In 2014, the company settled a case with over 15,000 Nigerians involved in the fishing industry who said they were affected by two oil spills, after claims were made to the U.K. High Court. Four months before the case was due to go to trial Shell, which has its primary stock-exchange listing in the U.K., agreed to pay 55 million British pounds, equivalent to $76 million…  

The January 2021  verdict tells oil majors that “when things go wrong they will be held to account and very likely held to account where their parent company is based,” said Mr. Day, adding that the ruling could spark more such actions.

A Present for the Earth: Reducing Plastic Leakage

Approximately 8 million metric tonnes of plastic litter flow to the ocean annually, and only 9% of plastic waste ever produced has been recycled….Another major issue relates to microplastics – those plastics that are smaller than 5 millimeters, and that pose increasing environmental, economic and health hazards… Discarded plastics break down into these smaller particles through natural weathering processes. Microplastics can enter water bodies through different pathways, including atmospheric deposition, run-off from land, roads and through municipal wastewater.

A review of technical solutions from source to sea explores a set of innovative tech solutions. Among these potential technologies include:

  • Introducing debris-cleanup boats, debris sweepers and sea-bins to remove plastics and other wastes carried into water bodies;
  • Protecting large bodies of water by introducing wetlands along coastlines;
  • Secondary and tertiary wastewater treatment which relies on membrane filtration to prevent microplastics entering rivers and lakes;
  • Advanced coagulation technology to make water contaminated with microplastics drinkable;
  • Promoting sustainable waste management practices to reduce plastic leakage.

A key principle of this work is preventing untreated wastewater, which is often packed with plastics and microplastics, from entering the environment in the first place.  The wastewater coming from urban residential, industrial and commercial settings is full of contaminants including plastics, microplastics and other debris…

Time for Burial: Last Repository for Nuclear Waste, Germany

Germany published on September 28, 2020 a list of potential storage sites for radioactive waste as part of its plans to exit nuclear power, dropping the Gorleben salt dome in Lower Saxony from the running.  The 444-page list of sites, to be assessed by 2031 for use from 2050 to hold waste currently in interim storage at nuclear plants, was published by Germany’s Federal Agency for Final Storage (BGE).  Some 90 locations, including parts of Lower Saxony, Bavaria, Baden Wuerttemberg and eastern German states, have been found to be potentially suitable after BGE undertook preliminary mapping that revealed 54% of German territory could be satisfactory.

Taking three years, the process identified salt, clay and crystalline, above all granite, formations, stressing the criteria were science-based, without political influence.  No location was predetermined, said Stefan Studt, head of BGE’s managing board, at a news conference. “Any region in today’s list would take a long, long time to become the actual final space,” he said. Germany had been on a course to exit nuclear power since 2000 but hastened the plan, now set for 2022, following the Fukushima nuclear disaster in 2011.

Gorleben, which became the focus of anti-nuclear protests in the 1970s, failed on three points related to retention, hydrochemical and overall geological qualities, so that it could not be ruled out that aquifers may come into contact with salt, said Steffen Kanitz, a BGE board member.

Banning Gasoline Cars: Better than subsidies and taxes

More than a dozen countries say they will prohibit sales of petrol-fueled cars by a certain date. On September 23rd, 2020,  Gavin Newsom, California’s governor, pledged to end sales of non-electric cars by 2035. Such bans may look like window-dressing, and that could yet in some instances prove to be the case. But in the right circumstances, they can be both effective and efficient at cutting carbon.

Fully electric vehicles are not yet a perfect substitute for petrol-consuming alternatives. They are often more expensive, depreciate faster, and have a lower range of travel and more limited supporting infrastructure, like charging stations or properly equipped mechanics. But the number of available electric models is growing, and performance gaps are closing. A recent analysis concludes that in such conditions—when electric vehicles are good but not perfect substitutes for petrol-guzzlers—a ban on the production of petrol-fueled cars is a much less inefficient way to reduce emissions than you might think.

If electric vehicles were in every way as satisfactory as alternatives, it would take little or no policy incentive to flip the market from petrol-powered cars to electric ones. If, on the other hand, electric cars were not a good substitute at all, the cost of pushing consumers towards battery-powered vehicles would not be worth the savings from reduced emissions. Somewhere in between those extremes, both electric and petrol-powered cars may continue to be produced in the absence of any emissions-reducing policy even though it would be preferable, given the costs of climate change, for the market to flip entirely from the old technology to the new. Ideally, the authors reckon, this inefficiency would be rectified by a carbon tax, which would induce a complete transition to electric vehicles. If a tax were politically impossible to implement, though, a production ban would achieve the same end only slightly less efficiently—at a loss of about 3% of the annual social cost of petrol-vehicle emissions, or about $19bn over 70 years… A shove may work as well as a nudge.

The Industrial Chicken and the US-China Rivalry

Animal diseases, the US-China trade war and covid-19 have all disrupted, or threatened to disrupt, industrial chicken supplies and supply chains…The unsentimental logic of high-performance poultry-rearing is easy to grasp. “White-feather meat chickens”, as they are known in China, grow to 2.5kg in 40 days. Homegrown varieties of “yellow-feather chicken”, descended from backyard fowl, take twice as long to mature and will only ever weigh half as much…

Half a century ago meat in China was a rare luxury. Now, many see it as a daily necessity. In the meantime, the country’s supplies of farmland and clean water have not grown. Agriculture remains blighted by food-safety scandals, the rampant use of fake or illegal animal medicines, and disease outbreaks. Small surprise, then, that Chinese leaders give frequent speeches about food security. A puzzle lurks, though. Leaders also call for self-reliance in key technologies. And in the case of broiler chickens, those two ambitions—rearing meat efficiently and avoiding dependence on imports—are in tension.

The chicken imported into China are the fifth-generation descendants of pedigree birds whose bloodlines represent 80 years of selection for such traits as efficient food-to-meat conversion, rapid growth, strong leg bones and disease resistance. After waves of consolidation, the industry is dominated by two firms, Aviagen (based in Alabama and owned by the ew Group of Germany) and Cobb (owned by Tyson, an American poultry giant).

The most valuable pedigree birds never leave maximum-security farms in America and Britain: a single pedigree hen may generate 4m direct descendants. Their second-generation offspring are flown to breeding sites dispersed between such places as Brazil, Britain and New Zealand, in part to hedge against supply shocks when avian influenzas and other diseases close borders. Day-old third-generation chicks are air-freighted to Jinghai Poultry, a company in China, and other places, which spend six months growing them and breeding them in climate-controlled, artificially lit indoor facilities. In all, China imports 1.6m third-generation white-feather chicks a year.

Jinghai  Poultry hatches 8m fourth-generation, “parent stock” chickens annually. The company sells some to other agri-businesses. It breeds from the rest to produce fifth-generation chicks. These are “meat chickens”, consumed in fast-food outlets, schools and factory canteens, or as chicken parts sold in supermarkets. Yellow-feather chickens, deemed tastier by Chinese cooks, account for most whole birds sold in markets.

Chinese breeders have long tried to create local varieties with bloodlines available in-country… In September 2019, the State Council, China’s cabinet, issued a paper on livestock-rearing that set self-sufficiency in poultry as a goal, calling meat-chicken breeding a priority. Big foreign firms have resisted appeals from officials to send second-generation stock to China….Dependence on foreign bloodlines does carry risks. For several months recently New Zealand was one of the only countries able to send third-generation chicks to China, after other exporters suffered bird-flu outbreaks.

Li Jinghui, president of the China Broiler Alliance, an industry association, calls conditions ripe for China’s “brilliant” scientists to develop local birds… But to develop a domestic breed from scratch would take years, and if it does not meet market needs, a firm could spend a fortune “without much to show for it”…Without a stronger animal-health system and environmental controls, biotechnology alone cannot help China to develop world-class agriculture. Moreover, a long-standing Chinese strategy—bullying foreign firms to hand over intellectual property—is counter-productive now.

1 Million Tons Radioactive Water Release at Sea: Fukushima, Japan

On October 19, 2020, China urged the Japanese government to “cautiously” consider whether to release treated radioactive water in the sea from the Fukushima No. 1 nuclear power plant. China’s remarks came days after it was reported by Japanese media that an official decision on the discharge of the water from the nuclear plant may be made by the end of October 2020. The water has been treated using an advanced liquid processing system, or ALPS, to remove most contaminants other than the relatively less toxic tritium and is stored in tanks on the facility’s premises.

But space is expected to run out by the summer of 2022, with contaminated water increasing by about 170 tons per day. As of September 2020, the stored water totaled 1.23 million tons and continues to grow.

Your Brain on Electro-Magnetic Fields

Current cockpits are flooded with radio frequency (RF) noise from on-board emissions, communication links, and navigation electronics, including strong electromagnetic (EM) fields from audio headsets and helmet tracking technologies. Pilots often report minor cognitive performance challenges during flight, and from 1993 to 2013, spatial disorientation in US Air Force pilots accounted for 72 Class A mishaps, 101 deaths, and 65 aircraft lost. It has been hypothesized that the cockpit RF and EM fields may influence cognitive performance including task saturation, misprioritization, complacency and Spatial Disorientation. However, EM fields and radio waves in cockpits are not currently monitored, little effort has been made to shield pilots from these fields, and the potential impacts of these fields on cognition have not been assessed.

Recent DARPA-funded research has demonstrated that human brains sense magnetic fields, like those used by animals for navigation, and that this process is “jammed” (i.e., disrupted) by radio waves (RF), impacting brainwaves and behavior. Furthermore, recent findings were the first to show that even weak RF fields and “earth strength” magnetic fields have measurable, reproducible effects on human brainwaves and unconscious behavior in a controlled environment. Current tactical audio headsets project magnetic fields up to 10 times earth strength, the effects of which can now be measured experimentally in a similar controlled environment.

[Phase II of the project will involve] developing next generation sensor suite capable of measuring the ambient EM/RF conditions in a military aircraft cockpit environment or a suitably similar analogue. This system must enable measurement of RF intensity vs frequency as well as RF absorption by various tissues in the human body and brain…The goal of Phase II experimentation will be to, not only identify any impacts of the cockpit EM/RF conditions that negatively impact pilot cognitive function or physiological sensor function, but also to develop and test various mitigation strategies to protect against these effects…


If this research and development effort reveals negative impacts of cockpit EM/RF environments on human cognitive function or physiological sensor performance, it is expected to generate interest from the commercial airline industry as well as other industries in which humans are exposed to similar EM/RF conditions

Severe Damage to Beliefs Lasting a Lifetime: covid-19

According to a new study  “Scarring Body and Mind: The Long-Term Belief-Scarring
Effects of COVID-19
” the largest economic cost of the COVID-19 pandemic could arise from changes in behavior long after the immediate health crisis is resolved. A potential source of such a long-lived change is scarring of beliefs, a persistent change in the perceived probability of an extreme, negative shock in the future. Even if a vaccine cures everyone in a year, the COVID-19 crisis will leave its mark on the US economy for many years to come because of the mass revision of beliefs that lasts through a lifetime. Even before the COVID-19 pandemic, people were aware of the disruptive impacts that a pandemic could theoretically have on their lives and the economy. But the tangible, persistent and severe harms associated with an actual pandemic change beliefs about the probability of another similar shock in ways that abstract knowledge cannot.

Living Insecticides: OX5034 Mosquito Obliterates Iteslf

A plan to release over 750 million genetically modified mosquitoes into the Florida Keys in 2021 and 2022 received final approval from local authorities, against the objection of many local residents and a coalition of environmental advocacy groups. The proposal had already won state and federal approval.

Approved by the Environment Protection Agency in May 2020, the pilot project is designed to test if a genetically modified mosquito is a viable alternative to spraying insecticides to control the Aedes aegypti. It’s a species of mosquito that carries several deadly diseases, such as Zika, dengue, chikungunya and yellow fever.  The mosquito, named OX5034, has been altered to produce female offspring that die in the larval stage, well before hatching and growing large enough to bite and spread disease. Only the female mosquito bites for blood, which she needs to mature her eggs. Males feed only on nectar, and are thus not a carrier for disease. The mosquito also won federal approval to be released into Harris County, Texas, beginning in 2021, according to Oxitec, the US-owned, British-based company that developed the genetically modified organism (GMO)…

In 2009 and 2010, local outbreaks of dengue feverleft the Florida Keys Mosquito Control District desperate for new options. Despite an avalanche of effort — from aerial, truck and backpack spraying to the use of mosquito-eating fish — local control efforts to contain the Aedes aegypti with larvicide and pesticide had been largely ineffective.
And costly, too. Even though Aedes aegypti is only 1% of its mosquito population, Florida Keys Mosquito Control typically budgets more than $1 million a year, a full tenth of its total funding, to fighting it…

The new male mosquito, OX5034, is programmed to kill only female mosquitoes, with males surviving for multiple generations and passing along the modified genes to subsequent male offspring….Environmental groups worry that the spread of the genetically modified male genes into the wild population could potentially harm threatened and endangered species of birds, insects and mammals that feed on the mosquitoes.

Forest Infernos and Food Self-Sufficiency

The Mega-Rice Project (MRP) — the conversion of 10,000 square km of peat forest into rice paddies — that was adopted in Indonesia in 1997, was a mega-failure. It produced hardly any rice because the peaty soil lacks the requisite minerals. Instead of spurring farming, the draining of the waterlogged forest with a 6,000km network of canals fuelled fire…. It was the biggest environmental disaster in Indonesia’s history.  Burning peat in 1997 on Kalimantan and the nearby island of Sumatra generated the equivalent of 13-40% of the average annual global emissions from fossil fuels. The MRP was abandoned in 1999 but its legacy endures in the infernos that have ravaged Kalimantan almost every year since.

As work begins in 2020 on the new plantation, is history poised to repeat itself? The government says it has learned from the past. Nazir Foead of the Peatland Restoration Agency says that tractors will steer clear of what remains of Central Kalimantan’s pristine peatlands…but the rest is covered in “shallow peat”, no more than 50cm deep, and so can be cultivated without cataclysm, he says.  Environmentalists are not convinced… Smouldering swamps belch vast amounts of carbon. In 2019, the fires that swept Indonesia emitted 22% more carbon than the conflagration in the Amazon rainforest did. 

But the government argues it must go ahead with the plantation, and quickly, in case covid-19 brings about food shortages… For decades the political elites “have been chasing this ideal of food self-sufficiency”, says Jenny Goldstein of Cornell University. Prabowo Subianto, the defence minister, is one of its greatest champions.

How to Poison a Population: War and Persistent Oil Pollution

Oil pollution in Syria has been a growing concern since the 2011 onset of a civil war that has taken a toll on oil infrastructure and seen rival powers compete over control of key hydrocarbon fields. In the Kurdish-held northeast, a large storage facility in the Rmeilan oil field in Hasakeh province is of particular concern, according to the Dutch peace organisation PAX. [A River of Death, pdf] Oil leaks from the Gir Zero storage facility have been suspected since at least 2014, the latest in March 2020, it said in a June report. Thousands of barrels have leaked out into creeks in the area over the past five years, threatening the health and livelihoods of people in dozens of villages….

The major Rmeilan field controlled by the Kurdish administration, located near a US airbase, has been among the Syrian Kurds’ most prized assets since regime forces withdrew early on in the war. But oil wealth comes at a heavy cost for livestock farmers
whose sheep and cows have died because they drank oil contaminated water.

Residents too suffer heavily from the pollution because  of the foul odour of gas and crude oil wafting over the area… Compounding the situation, makeshift oil refineries have cropped up across the northeast in recent years, dumping oil waste in the waterways…These informal refineries receive oil from nearby fields and process it to provide benzine, gasoline and diesel to locals.

Global Nuclear Waste Movements: from Estonia to Utah

Regulators are weighing whether a local uranium company can import the material for processing at a mill near the border of a Native American reservation. For Energy Fuels Inc , the shipment represents an economic lifeline, after the company posted an operating loss of $7.8 million for the first quarter of 2020. Its president in March 2020 described the U.S. uranium industry as being “on the cusp of complete collapse.”
But for the Ute Mountain Ute Tribe living near the facility – the only operational uranium mill in the United States – the proposal has stoked fears that tribal land will become a dumping ground for global radioactive waste. Both the White Mesa mill and the tribal reservation are in San Juan County, Utah’s poorest.

The mill, built in 1979, was only meant to process conventional uranium ores from the Colorado Plateau for up to 20 years, the tribe says. The Navajo Utah Commission and Navajo Nation have also that the company’s application be rejected. “The state of Utah must recognize and acknowledge the reality that the mill is far past its design life and no longer a conventional uranium mill, but, instead, a radioactive waste dump seeking to operate for decades, if not a millennium,” the Ute Mountain Ute Tribe said in a document submitted to the state….

The 660 tons of powdered material in question, now sitting in 2,000 drums at a plant on the Estonian coast near the Russian border, would be Energy Fuels’ first-ever radioactive import from outside North America. The powder is a byproduct from tantalum and niobium mining by Estonian company Silmet, which contains uranium. But it cannot stay within Estonia, where there is no licensed facility for reprocessing radioactive material. Energy Fuels says there is enough uranium in that byproduct that it is worth processing. Opponents say Energy Fuels is simply taking in waste, which would be stored on site. According to Energy Fuels business from the shipment would help the company keep its 70 workers employed.

Energy Fuels anticipates demand for domestic uranium could rise, after the Trump administration in April 2020 proposed a $1.5 billion federal uranium reserve that would purchase uranium from domestic producers. Such a reserve, however, would need Congressional approval – a major hurdle. The reserve was one of the main proposals to come from a federal Nuclear Fuel Working Group aimed at reviving the U.S. uranium and nuclear industry. The United States currently imports over 90% of its uranium from abroad for its reactors.

Fatalism about Plastics: Intractable Plastics Pollution

The annual inflow of plastic could nearly triple from 2016 to 2040, the study found, and even if companies and governments meet all their commitments to tackle plastic waste, it would reduce the projection for 2040 by only 7%, still a more-than twofold increase in volume.  The study’s authors, the nonprofit Pew Charitable Trust and sustainability consulting firm Systemiq Ltd., set out a range of measures to stem the flow and called on businesses and governments to do more to reduce the use of plastic. 

The study attributes the surge to a growing global population using more plastic per person. Other factors include greater use of nonrecyclable plastics and an increasing share of consumption occurring in countries with poor waste management. China and Indonesia are likely the top sources of plastic reaching the oceans, accounting for more than a third of the plastic bottles, bags and other detritus washed out to sea, according to a study published in 2015 by Jenna Jambeck, an environmental engineer at the University of Georgia.

Over the past two years China has been making strides to improve waste management, including banning the import of plastic and other waste from developed countries like the U.S., which for decades have shipped much of their trash overseas. Indonesia has implemented its own restrictions on trash coming in from overseas, while lawmakers in the U.S. are increasingly trying to find ways to improve the country’s domestic recycling rates as export markets vanish.

They found that flexible plastic packaging—particularly items like potato-chip bags and food pouches, which are made of several materials and typically aren’t recycled—accounts for a disproportionate amount of ocean plastic. The As You Sow report said companies should stop selling products in flexible plastic until it is recycled or composted in significant amounts. Companies, in response, have been redesigning flexible packaging to promote recycling. For example, Nestle recently began selling a line of Gerber baby-food pouches made from a single material. But hurdles remain, particularly around collection and sorting of the packaging…

The amount of plastic flowing into the oceans could be reduced by as much as 80% over the next 20 years through a combination of reduced plastic use, increased recycling, alternatives to problematic packaging like plastic pouches and better waste management, the Pew-Systemiq study said…

Radioactive Water Dumping and Human Rights

In the aftermath of the Fukushima Daiichi nuclear disaster, [UN Special Rapporteurs  have] consistently raised concerns about the approaches taken by the government of Japan. UN Special Rapporteurs have been concerned that raising of “acceptable limits” of radiation exposure to urge resettlement violated the government’s human rights obligations to children.

UN Special Rapporteurs have been concerned of the possible exploitation of migrants and the poor for radioactive decontamination work. Their most recent concern is how the government used the COVID-19 crisis to dramatically accelerate its timeline for deciding whether to dump radioactive wastewater accumulating at Fukushima Daiichi in the ocean

The communities of Fukushima, so devastated by the tragic events of March 11, 2011, have expressed their concerns and opposition to the discharge of the contaminated water into their environment. It is their human right to an environment that allows for living a life in dignity, to enjoy their culture, and to not be exposed deliberately to additional radioactive contamination. Those rights should be fully respected and not be disregarded by the government in Tokyo. The discharge of nuclear waste to the ocean could damage Japan’s international relations. Neighboring countries are already concerned about the release of large volumes of radioactive tritium and other contaminants in the wastewater.

Japan has a duty under international law to prevent transboundary environmental harm. More specifically, under the London Convention, Japan has an obligation to take precaution with the respect to the dumping of waste in the ocean.

Indigenous peoples have an internationally recognized right to free, prior and informed consent. This includes the disposal of waste in their waters and actions that may contaminate their food. No matter how small the Japanese government believes this contamination will be of their water and food, there is an unquestionable obligation to consult with potentially affected indigenous peoples that it has not met…The disaster of 2011 cannot be undone. However, Japan still has an opportunity to minimize the damage…There are grave risks to the livelihoods of fishermen in Japan and also to its international reputation. Again, I urge the Japanese government to think twice about its legacy: as a true champion of human rights and the environment, or not.

Air Pollution: the Microplastics We Breath

 Scientists measured microplastics — tiny particles and fibers of plastic that can float in the air like dust — and found that over 1,000 tons a year are falling into wilderness areas and national parks in the western U.S.  Janice Brahney of Utah State University and her team identified samples of microplastics and other particulates collected over 14 months in 11 national parks and wilderness areas to create the study published in the journal Science, on June 12, 2020.  Pieces of plastic less than 5 mm in length, or microplastics, occur in the environment as a consequence of plastic pollution…

The presence of microplastics in oceans and water supplies has been a matter of concern for some time, but the impact of airborne microplastics is a relatively new area of study. Though microplastics are found nearly everywhere on Earth, the sources and processes behind their ubiquitous distribution, or the “global plastic cycle,” remain vaguely understood.  Initially overlooked, recent studies have suggested that long-range atmospheric transport plays an important role in carrying microplastic pollution vast distances and to remote locations

Examination of weekly wet and monthly dry samples from 11 sites allowed the authors to estimate that more than 1,000 tons of microplastics are deposited onto protected lands in the western U.S. each year, equivalent to more than 123 million plastic water bottles.

The ubiquity of microplastics in the atmosphere has unknown consequences for humans and animals, but the research team observed sizes of particles that were within the ranges that accumulate in lung tissue. Moreover, the accumulation of plastic in the wilderness areas and national parks could well influence the ecosystems in complicated ways.

The Cracks on the Nuclear Runit Tomb

Excerpts from the US Department of Energy Report on the Nuclear Runit Dome

The Runit Dome is a containment structure on Runit Island, located on Enewetak Atoll.  Enewetak Atoll is a former U.S. atmospheric nuclear weapons test site located approximately 2,300 miles west of Hawaii in the northwest Pacific Ocean. The Runit Dome,  which was built in the late 1970s, contains over 100,000 cubic yards of contaminated soil and  debris [from the US nuclear weapons testing] that were encapsulated in concrete inside an unlined nuclear test crater, the Cactus Crater, on the north end of Runit Island. The site has remained a concern to the people of Enewetak. 

The Runit Dome is not in any immediate danger of collapse or failure, and the exterior concrete covering the containment structure is still serving its intended purpose, effectively reducing the natural erosion of the waste pile below by wind and water. Visual surveys of the exterior  concrete of the Cactus Crater containment structure have revealed the presence of cracks and spalls in the concrete cap. However, these cracks and spalls in the exterior concrete cap do not form sites for external or internal radiation exposure that impact or endanger human health or
the environment, or wildlife.

DOE has performed preventative maintenance on exterior surfaces of the containment structure, which will aid in the determination of any changes that
may occur in the condition of the concrete in the future. Any concerns about the imminent failure or collapse of the structure are unfounded.

The main safety concern to humans associated with leakage of radioactive waste from the Cactus Crater containment structure is the uptake of fallout radioactivity in marine foods. There are no data to suggest that the Cactus Crater containment structure, or more specifically, the radioactive material encapsulated in Cactus Crater, is currently having a measurable adverse effect on the surrounding environment or on the health of the people of Enewetak. However, DOE is in the process of establishing a groundwater radiochemical analysis program that is designed to provide scientifically substantiated data that can be used to determine what, if any, effects the dome contents are having, or will have, on the surrounding environment now
and in the future.

Long-term trends in the concentration of Pu in lagoon waters derived from retrospective analysis of a coral core collected off Runit Island show levels of Pu in lagoon waters are systematically decreasing. These data provide compelling evidence that the construction of the Runit Dome has had, and continues to have, a negligible impact on the wider marine environment….

The Cactus Crater containment structure remains vulnerable to wave driven over wash and flooding caused by storm surge and potential effects of sea level rise… It is
anticipated that any measured or modeled effects of storm events may help provide a better understanding of the long-term consequences of sea-level rise on mass-transport of dome derived radionuclides.

Everyone for Themselves: COVID-19 Drug Reserved for U.S.

On June 29, 2020 the US Department of Health and Human Services (HHS) announced an agreement to secure large supplies of the drug remdesivir for the United States from Gilead Sciences through September, allowing American hospitals to purchase the drug in amounts allocated by HHS and state health departments….HHS has secured more than 500,000 treatment courses of the drug for American hospitals through September. This represents 100% of Gilead’s projected production for July (94,200 treatment courses), 90% of production in August (174,900 treatment courses), and 90% of production in September (232,800 treatment courses), in addition to an allocation for clinical trials. A treatment course of remdesivir is, on average, 6.25 vials.

Hospitals will receive the product shipped by AmerisourceBergen and will pay no more than Gilead’s Wholesale Acquisition Price (WAC), which amounts to approximately $3,200 per treatment course.

No Clean-Up, No Justice: Ogoniland, Nigeria

The UN Environment Programme in 2011 proposed the creation of a $1 billion fund to repair the damage done by decades of crude spills in the Ogoniland area in southeastern Nigeria. However, progress has been poor and the little work that has been done is sub-standard, advocacy groups including Amnesty International reported in June 2020.  “Research reveals that there is still no clean-up, no fulfillment of ‘emergency’ measures, no transparency and no accountability for the failed efforts, neither by the oil companies nor by the Nigerian government,” the groups said.

Shell’s Nigerian unit pumped oil in Ogoniland until 1993, when the company withdrew amid increasing protests against its presence. Even though the Hague-based company no longer produces crude in the area, a joint venture operated by Shell Petroleum Development Company, or SPDC, still owns pipelines that crisscross the region.

A government agency responsible for overseeing the clean-up, the Hydrocarbon Pollution Remediation Project, known as Hyprep, was finally set up in 2017 after several false starts, but it’s failing to deliver. …“Hyprep is not designed, nor structured, to implement a project as complex and sizable as the Ogoniland clean-up,” the report cites UNEP as saying in 2019

Oil Spills of Sudan, Humanity for Africa, and East African Court of Justice

The East African Court of Justice delivered in June 2020 a temporary injunction order to the country’s Minister for Justice, the Greater Pioneer Operating Company (GPOC), and the Dar Petroleum Operating Company. The Court approved the application by Hope for Humanity Africa (H4HA), a non-governmental organization (NGO), which sought to highlight the environmental damage caused by oil spills… The NGO contends that: “Over 47,249 of the local population in Upper Nile State and 60,000 in Unity State are at risk of being exposed to the oil pollution this is because the local population depends on the wild foods for survival, the contaminated swamps, streams and rivers waters for cooking, drinking, washing, bathing and fishing.”…

The H4HA is looking for an injunction to stop multiple companies from exporting oil from the region, including CNPC of China, Petronas of Malaysia, and Oil & Natural Gas Corp. of India (ONGC)

The Big Trash Burners: Does it Make Sense to Incinerate Waste?

Global waste is expected to hit 3.4 billion tons by 2050 from 2.01 billion tons in 2016, according to the World Bank. As recycling programs encounter challenges and landfills in the U.S. and Europe reach capacity or face regulations making them more expensive, incinerators are becoming the most viable option for many municipalities to deal with much of their garbage. England now burns more municipal waste than it recycles or landfills. China—already the world’s biggest trash burner—is building more incinerators. And incineration companies say, for the first time in years, expansion projects are on the table in the U.S., although the industry faces significant legal and community challenges. Overall, incinerator-plant capacity is forecast to rise 43% globally between 2018 and 2028, according to Ecoprog, a consulting firm…..

Another growth driver is a European Union target for member states to cap the amount of municipal trash they send to landfill at 10% by 2030. Local communities and environmental groups have launched strong opposition to expansion of incineration plans, citing environmental and public-health concerns. Incinerator plants are also called waste-to-energy plants since the heat from burning trash is used to generate electricity, and many governments classify that electricity as renewable energy, a characterization opponents dispute…..But advocates for clean energy…say that while some energy is recovered by burning, recycling or composting garbage would save far greater amounts of energy.

Critics also say cities that own their incinerator plants have little incentive to pursue waste-reduction efforts because the plants are designed to run at full capacity. “Many countries are over-investing in incineration to cut down on landfilling, which will eventually lock them into burning,” said Janek Vähk, development and policy coordinator for Zero Waste Europe.

Japan’s Nuclear Bombs

On May 13, Japan’s Nuclear Regulation Authority announced that the nuclear fuel reprocessing plant in Rokkasho, Aomori Prefecture, had met new safety standards created after the March 11, 2011, earthquake and tsunami….The Rokkasho plant is a 3.8 million square meter facility designed to reprocess spent nuclear fuel from the nation’s nuclear reactors.  Construction began in 1993. Once in operation, the plant’s maximum daily reprocessing capacity will be a cumulative total of 800 tons per year.  During reprocessing, uranium and plutonium are extracted, and the Rokkasho plant is expected to generate up to eight tons of plutonium annually.

Both are then turned into a mixed uranium-plutonium oxide (MOX) fuel at a separate MOX fabrication plant, also located in Rokkasho, for use in commercial reactors. Construction on the MOX facility began in 2010 and it’s expected to be completed in 2022.  Japan had originally envisioned MOX fuel powering between 16 and 18 of the nation’s 54 commercial reactors that were operating before 2011, in place of conventional uranium.  But only four reactors are using it out of the current total of nine officially in operation. MOX fuel is more expensive than conventional uranium fuel, raising questions about how much reprocessed fuel the facilities would need, or want.

The Rokkasho reprocessing plant can store up to 3,000 tons of spent nuclear fuel from the nation’s power plants on-site. It’s nearly full however, with over 2,900 tons of high-level waste already waiting to be reprocessed.

Why has it taken until now for the Rokkasho plant to secure approval from the nuclear watchdog?   Decades of technical problems and the new safety standards for nuclear power that went into effect after the 2011 triple meltdown at the power plant in Fukushima Prefecture have delayed Rokkasho’s completion date 24 times so far. It took six years for the plant to win approval under the post-3/11 safety standards…By the time of the NRA announcement on May 13, 2020, the price tag for work at the Rokkasho plant had reached nearly ¥14 trillion.

Japan is the only non-nuclear weapons state pursuing reprocessing. But as far back as the 1970s, as Japan was debating a nuclear reprocessing program, the United States became concerned about a plant producing plutonium that could be used for a nuclear weapons program.  The issue was raised at a Feb. 1, 1977, meeting between U.S. Vice President Walter Mondale and Prime Minister Takeo Fukuda.  “Reprocessing facilities which could produce weapons grade material are simply bomb factories,” noted a declassified U.S. State Department cable on the meeting. “We want to cooperate (with Japan) to keep the problem under control.”

The U.S. oppose the Rokkasho plant’s construction in 1993, following an agreement in 1988 between the two countries on nuclear cooperation. ..The U.S.-Japan nuclear agreement meant the U.S. would give advance consent for Japan to send spent nuclear fuel to the United Kingdom and France — states with nuclear weapons — for reprocessing until Rokkasho was running at full-scale.

Currently, Japan has nearly 45 tons of plutonium stockpiled, including 9 tons held by domestic utilities. Another 21.2 tons is in the United Kingdom and France is holding 15.5 tons under overseas reprocessing contracts.

Thus, Japan finds itself caught between promises to the international community to reduce its plutonium stockpile through reprocessing at Rokkasho, and questions about whether MOX is still an economically, and politically, viable resource — given the expenses involved and the availability of other fossil fuel and renewable energy resources.

Can Traditional Medicine Cure COVID-19? China’s Take

Around the world officials are advising people to be wary of alternative treatments for covid-19. The opposite is true in China, where remedies known as traditional Chinese medicine (TCM) are being heavily promoted by the state. In January 2020, as the crisis escalated, the health ministry listed TCM treatments among those it recommended for the disease. It sent nearly 5,000 specialists to Hubei to administer them to patients (including sufferers at a sports centre in Wuhan that was turned into a TCM hospital for people with mild symptoms). Now China is keen to promote its remedies abroad.  TCM practitioners have joined Chinese medical teams sent to help manage outbreaks in Cambodia, Iraq and Italy. In mid-March, 2020 state media quoted a Tanzanian health official saying that China’s use of TCM for covid-19 may be “a model” for Africa to follow…

The use of animals in TCM sometimes involves appalling cruelty. One of the TCM remedies that the health ministry has recommended for use in the treatment of covid-19 patients includes powdered bear bile. In China this is often extracted from live bears kept in grim farms even though its active ingredient can be created synthetically. In February 2020 China banned the sale of wild animals as food—close contact in markets between live specimens and merchants may have helped the coronavirus to leap from animal to human. But the new rules do not prevent trappers and breeders from selling animal parts for use in TCM.

Officials do not say that traditional remedies can cure covid-19. But they do claim that TCM can reduce death rates by preventing patients with mild or moderate symptoms from developing more serious ones. They also say that TCM can speed up recovery. A website set up by China Daily, a state newspaper, called “Fighting covid-19 the Chinese way”, says that TCM can “remove the trash which causes illness”, leaving the virus “no room to survive”.

Plastic Bags Back in Vogue: Blame COVID or Plastics Industry?

Plastic bags may make a temporary comback in some places because of COVID-19.
In a setback, albeit temporary, for efforts to combat plastic waste, many state and local governments have suspended plastic bag bans and are prohibiting the use of reusable bags to stem the spread of COVID-19. The plastics industry is pushing for such measures, causing environmentalists to cry foul. San Francisco, which has been at the forefront of single-use plastics restrictions, issued an order “not permitting customers to bring their own bags, mugs, or other reusable items from home” as a measure “to prevent unnecessary contact.” Maine is delaying enforcement of its plastic bag ban to Jan. 15, 2021, after originally planning to roll it out on April 22—Earth Day….

The plastics industry has been advocating for such measures. In recent weeks, Bag The Ban, an initiative sponsored by the American Recyclable Plastic Bag Alliance, has endorsed editorials in newspapers such as the Boston Herald and the New Hampshire Union Leader advocating use of plastic bags to protect grocery workers from COVID-19.

Writing to the US Department of Health and Human Services, the Plastics Industry Association made a similar point. “Single-use plastic products are the most sanitary choice when it comes to many applications.” The association cited research on reusable bags, including a 2011 study from Loma Linda University and the University of Arizona that tested bags from shoppers selected randomly at the grocery store and found bacteria such as E. coli on 8% of them. It also pointed to a 2012 outbreak of norovirus in Oregon linked to use of a reusable food bag and cited a 2019 study from Portugal that found bacteria in bags.

U.S. Desperation for Face Masks: Wild West or Piracy?

From Europe to South America, U.S. allies are complaining about the superpower’s “Wild West” tactics in outbidding or blocking shipments to buyers who have already signed deals for vital medical supplies. …”Money is irrelevant. They pay any price because they are desperate,” one high-level official in German Chancellor Angela Merkel’s ruling CDU/CSU group told Reuters….In April 5, 2020, US President Trump said he was signing a directive to stop the export of N95 respirator masks, which provide essential protection for health-care workers, and other U.S. medical equipment. Furthermore, 3M, a US company, said that the White House had ordered it to stop all shipments to Canada and Latin America of respirators that it manufactures in the U.S., despite what 3M called “significant humanitarian implications.”

In another case, an order of 200,000 masks bound for Germany was diverted to the U.S….Germany’s Secretary of Interior Andreas Geisel called it an “act of modern piracy.” He stated that: “even in times of global crisis, you shouldn’t use Wild West methods.”

Can’t Treat Covid-19 with Flip-Flops

The U.S. Covid-19 response remains a work in progress—fragmented, chaotic, and plagued by contradictory messaging from political leaders, [such as the flip-flops on the use of face masks, see Stop Buying Face Masks , Learn How to Make Your Own Face Mask]. …

 “We don’t have a national plan,” says epidemiologist Michael Osterholm of the University of Minnesota, Twin Cities. “We are going from press conference to press conference and crisis to crisis … trying to understand our response.”…Even if lockdowns succeed at halting the virus…. the United States needs to marshal massive resources to monitor for new outbreaks and quickly contain them…. Identifying cases and contacts and isolating them will require a huge increase in public health workers at the local level….The absence of nationwide coordination highlights the division of legal power between the federal and state governments…. Governors, not federal officials, typically hold police powers to shut businesses and enforce curfews. But many are reluctant to invoke those powers and suffer the political costs without clear direction from above….“The closest comparison here, in terms of national mobilization, is a war. And there is no way the United States would fight a war as 50 separate states.”

Genes that Atttack Plastic

A common fixture in refrigerators, furniture and footwear, polyurethane plastic is pretty much always in high demand. Humans worldwide cycle through millions of tons of the durable substance each year, sending the bulk of what’s not recycled to garbage dumps, where it leaks toxic chemicals into the environment as it very slowly breaks down. At least one of Earth’s organisms sees the stuff as a boon: a bacterial strain called Pseudomonas sp.TDA1. This polyurethane-munching microbe seems to thrive in waste dump sites. Studying the Pseudomonas strain and the chemical strategies it deploys could someday help researchers put a small dent in the world’s plastic problem, which has cumulatively saddled the planet with more than 8 billion tons of slow-degrading synthetic material.

Pseudomonas sp. TDA1 is one of only a few microbes known to be tolerant to polyurethane plastic’s typically toxic properties. What’s more, the bacteria doesn’t just withstand the plastic’s harsh ingredients: it uses some of them as a food source… But while the bacterium can metabolize a subset of the chemicals in polyurethane plastic, it doesn’t seem able to break down these products completely. In-depth studies of Pseudomonas sp. TDA1 will reveal the genes crucial to these plastic-attacking abilities. Understanding how these genes and their products work could help scientists engineer synthetic approaches to tackling plastic in the future.

The Nuclear Reactors Buried in the Deep Sea

The Soviet Union used the waters east of Novaya Zemlya to dump reactors, spent nuclear fuel and solid radioactive waste from both the navy and the fleet of nuclear-powered civilian icebreakers. About 17,000 objects were dumped in the period from the late 1960s to the late 1980s. Most of the objects are metal containers with low- and medium level radioactive waste. The challenge today, though, are the reactors with high-level waste and spent uranium fuel, objects that will pose a serious threat to the marine environment for tens of thousands of years if nothing is done to secure them.

The reactors from the submarines K-11, K-19 and K-140, plus the entire submarine K-27 (in the Kara Sea) and spent uranium fuel from one of the old reactors of the Lenin-icebreaker have to be lifted and secured. Also, the submarine K-159 (in the Barents Sea) that sank north of Murmansk while being towed for decommissioning in 2003 have to be lifted from the seafloor, the experts conclude. A study report made for Rosatom and the European Commission has evaluated the costs of lifting all six objects, bringing them safely to a yard for decommissioning and securing the reactors for long-term storage. The estimated price-tag for all six will €278 millions, of which the K-159 is the most expensive with a cost of €57.5 millions. Unlike the submarines and reactors that are dumped in relatively shallow waters in the Kara Sea, the K-159 is at about 200 meters depth, and thus will be more difficult to lift.

Ethical Killing: Landmines

During the Gulf war of 1991, no fewer than 117,000 landmines were showered over Kuwait and Iraq by American planes. This barely dented the Pentagon’s vast stockpile of 19m. Just under a quarter of the devices scattered in the path of Saddam Hussein’s army were anti-personnel landmines (APLs), the sort that would soon be banned by the Anti-Personnel Mine Ban Convention of 1997, widely known as the Ottawa treaty. The Ottawa treaty has 164 parties, all of which ban the production and use of APL (anti-vehicle mines, among others, are still allowed). America is not among them. When the treaty was finalised, America declined to join (other holdouts include China, Cuba, Iran, Russia and Syria).

Landmines have a number of military uses. They are typically used to channel opposing armies away from particular areas and into others. A minefield can force an enemy to turn, which exposes their flank and makes them especially vulnerable, says Vincent Brooks, a retired general who commanded American forces in South Korea in 2016-18. They can also be used to “canalise” the enemy, channelling attackers into unfavourable terrain, where they may be more exposed to concentrated artillery fire. …But landmines are reviled weapons, and not without good reason. “They’re indiscriminate,”… Landmine casualties have fallen sharply over the years, but at least 2,000 people were killed or wounded by manufactured or improvised APLS in 2018, according to data collected by the Landmine and Cluster Munition Monitor, a research group. Laying a mine can cost a few dollars; clearing one can require $1,000.

The Pentagon has an answer to this. It says that it only possesses, would only produce and would only use “non-persistent” landmines with the capacity to self-destruct or, failing that, to self-deactivate, with a battery losing its charge, within 30 days (some models can blow themselves up in as little as a few hours). It claims that such features are remarkably reliable. …“When the technology is brought into the battlefield, we see that the actual data doesn’t match with the promises,” says Erik Tollefsen, head of Weapons Contamination for the International Committee of the Red Cross. He says that impressive reliability rates are usually derived from tests in sterile conditions, and prove wildly exaggerated in practice. In 2002 a report by the Government Accountability Office, an agency that audits the federal government, noted that during the Gulf war one in 10,000 mines were expected to remain active, which would have produced 12 duds. The actual figure was almost 2,000.

Others argue that there are perfectly viable alternatives to APLs….In particular, remotely activated mines (rather than victim-activated ones) are allowed under the treaty if the person triggering the device has the would-be victim in sight, although this makes them harder to use at range and hostage to a breakdown of communications. In 2018 Finland—a late and reluctant signatory to Ottawa, given its long border with Russia—said it was developing a new, remote-controlled variety of anti-personnel “bounding” mine that leaps into the air and fires metal bullets downward.

Human and Environmental Costs of Low-Carbon Technologies

Substantial amounts of raw materials will be required to build new low-carbon energy devices and infrastructure.  Such materials include cobalt, copper, lithium, cadmium, and rare earth elements (REEs)—needed for technologies such as solar photovoltaics, batteries, electric vehicle (EV) motors, wind turbines, fuel cells, and nuclear reactors…  A majority of the world’s cobalt is mined in the Democratic Republic of Congo (DRC), a country struggling to recover from years of armed conflict…Owing to a lack of preventative strategies and measures such as drilling with water and proper exhaust ventilation, many cobalt miners have extremely high levels of toxic metals in their body and are at risk of developing respiratory illness, heart disease, or cancer.

In addition, mining frequently results in severe environmental impacts and community dislocation. Moreover, metal production itself is energy intensive and difficult to decarbonize. Mining for copper,and mining for lithium has been criticized in Chile for depleting local groundwater resources across the Atacama Desert, destroying fragile ecosystems, and converting meadows and lagoons into salt flats. The extraction, crushing, refining, and processing of cadmium can pose risks such as groundwater or food contamination or worker exposure to hazardous chemicals. REE extraction in China has resulted  threatens rural groundwater aquifers as well as rivers and streams.

Although large-scale mining is often economically efficient, it has limited employment potential, only set to worsen with the recent arrival of fully automated mines. Even where there is relative political stability and stricter regulatory regimes in place, there can still be serious environmental failures, as exemplified by the recent global rise in dam failures at settling ponds for mine tailings. The level of distrust of extractive industries has even led to countrywide moratoria on all new mining projects, such as in El Salvador and the Philippines.

Traditional labor-intensive mechanisms of mining that involve less mechanization are called artisanal and small-scale mining (ASM). Although ASM is not immune from poor governance or environmental harm, it provides livelihood potential for at least 40 million people worldwide…. It is also usually more strongly embedded in local and national economies than foreign-owned, large-scale mining, with a greater level of value retained and distributed within the country. Diversifying mineral supply chains to allow for greater coexistence of small- and large-scale operations is needed. Yet, efforts to incorporate artisanal miners into the formal economy have often resulted in a scarcity of permits awarded, exorbitant costs for miners to legalize their operations, and extremely lengthy and bureaucratic processes for registration….There needs to be a focus on policies that recognize ASM’s livelihood potential in areas of extreme poverty. The recent decision of the London Metals Exchange to have a policy of “nondiscrimination” toward ASM is a positive sign in this regard.

A great deal of attention has focused on fostering transparency and accountability of mineral mining by means of voluntary traceability or even “ethical minerals” schemes. International groups, including Amnesty International, the United Nations, and the Organisation for Economic Co-operation and Development, have all called on mining companies to ensure that supply chains are not sourced from mines that involve illegal labor and/or child labor.

Traceability schemes, however, may be impossible to fully enforce in practice and could, in the extreme, merely become an exercise in public relations rather than improved governance and outcomes for miners…. Paramount among these is an acknowledgment that traceability schemes offer a largely technical solution to profoundly political problems and that these political issues cannot be circumvented or ignored if meaningful solutions for workers are to be found. Traceability schemes ultimately will have value if the market and consumers trust their authenticity and there are few potential opportunities for leakage in the system…

Extended producer responsibility (EPR) is a framework that stipulates that producers are responsible for the entire lifespan of a product, including at the end of its usefulness. EPR would, in particular, shift responsibility for collecting the valuable resource streams and materials inside used electronics from users or waste managers to the companies that produce the devices. EPR holds producers responsible for their products at the end of their useful life and encourages durability, extended product lifetimes, and designs that are easy to reuse, repair, or recover materials from. A successful EPR program known as PV Cycle has been in place in Europe for photovoltaics for about a decade and has helped drive a new market in used photovoltaics that has seen 30,000 metric tons of material recycled.

The Nightmare: Sabotaging 20 Million Nuclear Shipments

Nuclear and other radioactive material is hardest to protect when it is transported from point A to point B — more than half of the incidents of theft of radioactive material reported to the IAEA between 1993 and 2019 occurred while it was in transport.

Around 20 million shipments of nuclear and other radioactive material are regularly transported within countries and across borders each year. These materials are used in industry, agriculture and medicine, as well as in education. Some of them are also radioactive sources that are no longer useful, known as disused sources.

The aim of nuclear security during transport is to ensure that the material is secured throughout and that it is not used for criminal or malicious purposes. While the level of security differs depending on the sensitivity of the material, the fundamental elements of secure transport include physical protection, administrative measures, training and protection of information about the transport routes and schedule. In some cases, escort personnel may also need to be armed

“During conversion of our research reactor from high enriched to low enriched uranium fuel, we had to transport highly radioactive spent reactor fuel from the site to the airport to be sent back to the original manufacturer, and we had to transport the new low enriched uranium fuel from the airport to the facility,” said Yusuf A. Ahmed, Director of the Centre for Energy Research and Training in Nigeria, who was involved in the conversion project. “Although the transport time is only a few hours, there is a lot that can happen during that time, from simple traffic accidents to malicious interventions and sabotage of shipments.”

While only around 30 countries use nuclear power and therefore have significant amounts of nuclear materials to transport, almost all countries use radioactive sources.

Left to their Own Bad Devices: the Future of Ogoni Land in Nigeria

The decades-overdue clean-up of Ogoniland, after years of oil spills from the pipelines that criss-cross the region, is finally under way. But the billion-dollar project — funded by Nigeria’s national oil company and Royal Dutch Shell — is mired in allegations of corruption and mismanagement.  “We are not pleased with what is going on,” said Mike Karikpo, an attorney with Friends of the Earth International and a member of the Ogoniland team that negotiated the creation of the Hydrocarbon Pollution Remediation Project (Hyprep), the government body running the clean-up… 

Nigeria is Africa’s biggest oil producer, pumping out about 1.8m barrels per day. It provides roughly 90 per cent of the country’s foreign exchange and more than half of government revenues.  The clean-up began only the summer 2019, about a year after the first of an expected five tranches of $180m in funding was released to Hyprep. Mr Karikpo complains of a lack of transparency, alleging that planning, budgeting and awarding of contracts took place behind closed doors. Work started at the height of the rainy season, washing away much of the progress as contaminated soil collected for treatment was swept back into the environment…

Ogoniland, like the broader Niger Delta, has become more polluted and development has stalled, with little to show for the billions of dollars in crude that has been extracted. Critics have now accused Hyprep of being, like much of Nigeria’s oil sector, a vehicle for political patronage and graft. This year 16 companies were awarded contracts for the first phase of the clean-up, which — to the consternation of critics — focuses on the least contaminated parts of Ogoniland.

An investigation by the news site Premium Times found that almost all the companies were set up for other purposes, including poultry farming, car sales and construction, and had no experience of tackling oil pollution.  Meanwhile, insiders have questioned Hyprep’s capacity to handle such a massive project…

Shell and Hyprep have rejected the criticism.  Shell, which closed its Ogoniland operations in 1993, said it accepted responsibility “for spills arising from its operations”, but that some of the blame for the pollution must go to thieves who illegally tapped into pipelines and makeshift refining operations in the Delta’s creeks

540 Katrina Oil Spills Equal an Exxon Valdez Disaster

The federal agency overseeing oil and gas operations in the Gulf of Mexico after hurricane Katrina reported that more than 400 pipelines and 100 drilling platforms were damaged. The U.S. Coast Guard, the first responder for oil spills, received 540 separate reports of spills into Louisiana waters. Officials estimated that, taken together, those leaks released the same amount of oil that the highly publicized 1989 Exxon Valdez disaster spilled into Alaska’s Prince William Sound — about 10.8 million gallons…

While hurricanes gain speed due to the effects of climate change, the push for oil leasing in the Gulf of Mexico shows no sign of slowing down. In 2014, the Obama administration opened up 40 million new acres in the Gulf for oil and gas development. Four years later, the Trump administration announced plans to open up most of the rest, in what would be the largest expansion of offshore oil and gas drilling in U.S. history. Many of these 76 million acres are to be offered at reduced royalty rates to encourage additional near-shore drilling in Louisiana waters…

“In the Gulf, storms are predicted to be less frequent but more intense when they do come,” said Sunshine Van Bael, an ecologist at Tulane University who evaluated damage to marsh ecosystems from the BP oil spill. “One thing that storms do is, if oil has been buried underneath the marsh because it wasn’t rehabilitated, a storm could come along and whip that back up to the surface. So, the aftereffects of the oil spills might be greater [with climate change] since the storms are predicted to be more intense.”…

In 2009, a class-action lawsuit against Murphy Oil Corp. ended in a settlement requiring the company to pay $330 million to 6,200 claimants, including owners of about 1,800 homes in St. Bernard Parish. The damage occurred when one of Murphy’s storage tanks floated off its foundation during Katrina and dumped over a million gallons of crude oil into a square-mile segment of Meraux and Chalmette….

To date, more than $19 million has been paid out from the federal Oil Spill Liability Trust Fund to reimburse at least two oil companies for costs they incurred cleaning up oil they spilled during Katrina…

“We don’t normally penalize [companies] for act of God events,” Greg Langley of the Department of Environmental Quality said. “We just get right to remediation.”

Electronic Waste: The Death of Your Phone and the Duty to Resuscitate It

E-waste is the fastest-growing element of the world’s domestic waste stream, according to a 2017 report by the UN’s Global E-waste Monitor. Some 50m metric tonnes will be produced annually in 2020 — about 7kg for every person in the world. Just 20 per cent will be collected and recycled.  The rest is undocumented, meaning it likely ends up in landfill, incinerated, traded illegally or processed in a substandard way. That means hazardous substances spilling into the environment, poisoning the ground and people living nearby.

Heavy metals such as mercury, lead and cadmium — commonly found in LCD screens,  refrigerators and air-conditioning units — as well as chemicals such as CFCs and flame retardants  found in plastics can contaminate soil, pollute water and enter the food chain.  Research last year by Basel Action Network, an NGO, linked toxic e-waste shipped from Europe to  contaminated chicken eggs in Agbogbloshie — a Ghanaian scrapyard where 80,000 residents subsist by retrieving metals from electrical waste. Eating just one egg from a hen foraging in the scrapyard would exceed the European Food Safety Authority’s tolerable daily intake for chlorinated dioxins 220-fold.

Some appliances are more likely to be recycled than others. The recycling rate for big appliances, such as fridges and cookers, is about 80 per cent. That is because they are harder to dispose of and eventually get picked up, even when they are dumped by the kerb. Of small appliances, however,  barely one in five makes it to the recycling centre.  Across the world, governments are trying different ways to reduce e-waste and limit the amount that ends up in landfill.

For some time, EU countries have operated a one-for-one take-back system — which means that distributors need to take back, for free, an older version of any equipment they sell you. But since the rapid rise of online retailers, this has been harder to implement

In the end, all e-waste needs to be reduced to core metals. “It’s a bit like a mining activity.” In certain recycling  plants robots have been programmed to dismantle flatscreen TVs, extracting  precious metals such as cobalt or lithium, whose deposits are limited and increasingly valuable.  “One of the hardest things about recycling is that you are not sure how [the manufacturers] made  it.”   Companies are encouraged  to include this information on their devices. It could be a  file with instructions readable by robots that could then proceed with the dismantling, making the process “easier, cheaper and more circular”. However, manufacturers have so far kept a close guard on the design of their products.

Many pressure groups and lawmakers have concluded that improving recycling rates will not be  sufficient to tackle the global e-waste problem. Increasingly, they are advocating for the right to repair. In October 2019, the EU adopted a package of design measures to make household appliances more repairable.  Starting from March 2021, manufacturers selling certain household appliances will have to ensure  that spare parts are available for a number of years after their product has launched; that their  items can be easily disassembled (and so use screws not glue); and that they provide access to  technical information to repair professionals.

The rules cover appliances including refrigerators, washing machines, dishwashers and televisions.  But they do not extend to IT equipment such as laptops, tablets and mobile phones.  “The road to a new product is very easy, and the road to a successful repair very difficult,” says  Martine Postma, founder and director of Repair Café International Foundation, which celebrated  its 10th anniversary last year. Since its first repair event in Amsterdam in 2009, the organisation  has grown to nearly 2,000 repair groups in 35 countries around the world.  Now, it wants to collect more data about electronic gadgets, to see if it can plot “weak points” in  design that could help manufacturers make them more repairable.

Swept Under the Rug: Radioactive Dust and Brine in the Oil Industry

A salty substance called  “brine,” is  a naturally occurring waste product that gushes out of America’s oil-and-gas wells to the tune of nearly 1 trillion gallons a year, enough to flood Manhattan, almost shin-high, every single day. At most wells, far more brine is produced than oil or gas, as much as 10 times more. Brine collects in tanks, and workers pick it up and haul it off to treatment plants or injection wells, where it’s disposed of by being shot back into the earth

The Earth’s crust is in fact peppered with radioactive elements that concentrate deep underground in oil-and-gas-bearing layers. This radioactivity is often pulled to the surface when oil and gas is extracted — carried largely in the brine…

Radium, typically the most abundant radionuclide in brine, is often measured in picocuries per liter of substance and is so dangerous it’s subject to tight restrictions even at hazardous-waste sites. The most common isotopes are radium-226 and radium-228, and the Nuclear Regulatory Commission requires industrial discharges to remain below 60 for each. Some brine samples registered combined radium levels above 3,500, and one was more than 8,500. “It’s ridiculous that those who haul brine are not being told what’s in their trucks,” says John Stolz, Duquesne’s environmental-center director. “And this stuff is on every corner — it is in neighborhoods. Truckers don’t know they’re being exposed to radioactive waste, nor are they being provided with protective clothing.

“Breathing in this stuff and ingesting it are the worst types of exposure,” Stolz continues. “You are irradiating your tissues from the inside out.” The radioactive particles fired off by radium can be blocked by the skin, but radium readily attaches to dust, making it easy to accidentally inhale or ingest. Once inside the body, its insidious effects accumulate with each exposure. It is known as a “bone seeker” because it can be incorporated into the skeleton and cause bone cancers called sarcomas. It also decays into a series of other radioactive elements, called “daughters.” The first one for radium-226 is radon, a radioactive gas and the second-leading cause of lung cancer in the U.S. Radon has also been linked to chronic lymphocytic leukemia.

Oil fields across the country — from the Bakken in North Dakota to the Permian in Texas — have been found to produce brine that is highly radioactive. “All oil-field workers,” says Fairlie, “are radiation workers.” But they don’t necessarily know it.

The advent of the fracking boom in the early 2000s expanded the danger, saddling the industry with an even larger tidal wave of waste to dispose of, and creating new exposure risks as drilling moved into people’s backyards. “In the old days, wells weren’t really close to population centers. Now, there is no separation,” says City University of New York public-health expert Elizabeth Geltman. In the eastern U.S. “we are seeing astronomically more wells going up,” she says, “and we can drill closer to populations because regulations allow it.” As of 2016, fracking accounted for more than two-thirds of all new U.S. wells, according to the Energy Information Administration. There are about 1 million active oil-and-gas wells, across 33 states, with some of the biggest growth happening in the most radioactive formation — the Marcellus. …

There is little public awareness of this enormous waste stream, the disposal of which could present dangers at every step — from being transported along America’s highways in unmarked trucks; handled by workers who are often misinformed and underprotected; leaked into waterways; and stored in dumps that are not equipped to contain the toxicity. Brine has even been used in commercial products sold at hardware stores and is spread on local roads as a de-icer

But a set of recent legal cases argues a direct connection to occupational exposure can be made… Pipe cleaners, welders, roughnecks, roustabouts, derrickmen, and truck drivers hauling dirty pipes and sludge all were exposed to radioactivity without their knowledge and suffered a litany of lethal cancers. An analysis program developed by the Centers for Disease Control and Prevention determined with up to 99 percent certainty that the cancers came from exposure to radioactivity on the job, including inhaling dust and radioactivity accumulated on the workplace floor, known as “groundshine.”

“Almost all materials of interest and use to the petroleum industry contain measurable quantities of radionuclides,” states a never-publicly released 1982 report by the American Petroleum Institute, the industry’s principal trade group, passed to Rolling Stone by a former state regulator. Rolling Stone discovered a handful of other industry reports and articles that raised concerns about liability for workers’ health. A 1950 document from Shell Oil warned of a potential connection between radioactive substances and cancer of the “bone and bone marrow.” In a 1991 paper, scientists with Chevron said, “Issues such as risk to workers or the general public…must be addressed.”

“There is no one federal agency that specifically regulates the radioactivity brought to the surface by oil-and-gas development,” an EPA representative says. In fact, thanks to a single exemption the industry received from the EPA in 1980, the streams of waste generated at oil-and-gas wells — all of which could be radioactive and hazardous to humans — are not required to be handled as hazardous waste. In 1988, the EPA assessed the exemption — called the Bentsen and Bevill amendments, part of the Resource Conservation and Recovery Act — and claimed that “potential risk to human health and the environment were small,” even though the agency found concerning levels of lead, arsenic, barium, and uranium, and admitted that it did not assess many of the major potential risks. Instead, the report focused on the financial and regulatory burdens, determining that formally labeling the “billions of barrels of waste” as hazardous would “cause a severe economic impact on the industry.”…

There is a perception that because the radioactivity is naturally occurring it’s less harmful (the industry and regulators almost exclusively call oil-and-gas waste NORM — naturally occurring radioactive material, or TENORM for the “technologically enhanced” concentrations of radioactivity that accumulate in equipment like pipes and trucks.”…

In Pennsylvania, regulators revealed in 2012 that for at least six years one hauling company had been dumping brine into abandoned mine shafts. In 2014, Benedict Lupo, owner of a Youngstown, Ohio, company that hauled fracking waste, was sentenced to 28 months in prison for directing his employees to dump tens of thousands of gallons of brine into a storm drain that emptied into a creek that feeds into the Mahoning River. While large bodies of water like lakes and rivers can dilute radium, Penn State researchers have shown that in streams and creeks, radium can build up in sediment to levels that are hundreds of times more radioactive than the limit for topsoil at Superfund sites. Texas-based researcher Zac Hildenbrand has shown that brine also contains volatile organics such as the carcinogen benzene, heavy metals, and toxic levels of salt, while fracked brine contains a host of additional hazardous chemicals. “It is one of the most complex mixtures on the planet,” he says…

“There is nothing to remediate it with,” says Avner Vengosh, a Duke University geochemist. “The high radioactivity in the soil at some of these sites will stay forever.” Radium-226 has a half-life of 1,600 years. The level of uptake into agricultural crops grown in contaminated soil is unknown because it hasn’t been adequately studied.

“Not much research has been done on this,” says Bill Burgos, an environmental engineer at Penn State who co-authored a bombshell 2018 paper in Environmental Science & Technology that examined the health effects of applying oil-field brine to roads. Regulators defend the practice by pointing out that only brine from conventional wells is spread on roads, as opposed to fracked wells. But conventional-well brine can be every bit as radioactive, and Burgos’ paper found it contained not just radium, but cadmium, benzene, and arsenic, all known human carcinogens, along with lead, which can cause kidney and brain damage.

Brine as dust suppressant

Ohio, because of its geology, favorable regulations, and nearness to drilling hot spots in the Marcellus, has become a preferred location for injection wells. Pennsylvania has about a dozen wells; West Virginia has just over 50. Ohio has 225. About 95 percent of brine was disposed of through injection as of 2014. Government scientists have increasingly linked the practice to earthquakes, and the public has become more and more suspicious of the sites. Still, the relentless waste stream means new permits are issued all the time, and the industry is also hauling brine to treatment plants that attempt to remove the toxic and radioactive elements so the liquid can be used to frack new wells.

The Global Experiment with Malaria Vaccine Starts in African States

Thirty years in the making, RTS,S, the malaria vaccine, also known by its brand name, Mosquirix, targets Plasmodium falciparum, the most common and most lethal of four malaria parasite species. It is an answer to a dire need. After decades of declining numbers of cases and deaths, the fight against malaria has stalled. Parasites resistant to the most widely used treatment, called artemisinin-based combination therapy, are spreading, while malaria mosquitoes are increasingly resistant to insecticides. And yet the rollout in Malawi and in two other African countries, isn’t quite the breakthrough the field has been waiting for. Mosquirix’s efficacy and durability are mediocre: Four doses offer only 30% protection against severe malaria, for no more than 4 years. Some experts question whether that is worth the cost and effort

The biggest concerns, however, are about the vaccine’s safety. In the largest trial, children who received Mosquirix had a risk of meningitis 10 times higher than those who received a control vaccine. Mosquirix may not have triggered the meningitis cases—there are other possible explanations—but the possible risk worried the global health community so much that, rather than rolling out the vaccine across Africa, the World Health Organization (WHO) has decided to set up a pilot in Malawi, Ghana, and Kenya in which the vaccine will be given to hundreds of thousands of children.

The Malaria parasite  is a challenging target for a vaccine. It has a complex life cycle that begins when an infected female mosquito bites a human and spits Plasmodium cells called sporozoites into the bloodstream. They multiply in the liver, emerge as another cell type named merozoites, invade red blood cells, and continue to multiply. The blood cells burst, causing fever, headache, chills, muscle aches, and often anemia. (They also flood the blood with gametocytes—the parasite’s reproductive cells—ready to be picked up by the next mosquito.) Along the way, the parasite frequently changes its surface proteins. That makes it an elusive target for the immune system, and for a vaccine.

Mosquirix, developed in the 1980s by a team in Belgium at SmithKline-RIT, now part of GlaxoSmithKline (GSK), stimulates an immune response against a protein that occurs only on the sporozoites’ surface. To bolster the response, the research team fused the vaccine protein with a hepatitis B surface protein and added an adjuvant….

A relative outside, Danish anthropologist and vaccine researcher Peter Aaby of the Bandim Health Project in Guinea-Bissau, offered another argument against introduction. After reanalyzing the data from the biggest trial, Aaby discovered that although the vaccinated children had malaria less often, they did not die less often. Among girls, overall mortality was almost doubled, Aaby told his colleagues at the meeting. “This vaccine is killing girls,” he recalls saying. Whereas WHO expects the vaccine to save one life per 200 children vaccinated, Aaby believes one in 200 will die as a result of it; he predicts “a nightmare.”

Aaby and Christine Stabell Benn, a global health professor at the University of Southern Denmark, have an explanation. The married couple has studied routine vaccinations in Africa for decades and believes vaccines can “train” the immune system in ways that don’t affect just the target disease. Vaccines that contain a living, weakened pathogen—such as the vaccines against measles and tuberculosis—strengthen the immune system generally, Aaby and Stabell Benn say, making recipients better able to fight off other infections. But vaccines that contain a killed pathogen or only bits of it weaken the immune system, their theory goes—especially in girls, because their immune systems seem to respond more strongly to vaccines in general.

Does Fracking Cause Cancer? The Right to Know and the Duty to Protect

An increase in the number of teens and young adults diagnosed with a rare cancer in the southwest corner of Pennsylvania has caused the state to look for a link between fracking and the disease.The investigation was sparked by a spate of Ewing’s sarcoma cases in and around Washington County, which has more Marcellus Shale gas wells than any other county in the state. In April 2019 state Department of Health found that the cases didn’t constitute a statistically significant cancer cluster. But affected families and other residents lobbied the governor for an investigation.

 The region is home to coal mining, oil drilling, chemical plants and a former uranium-processing facility.  Each year, about 250 children in the U.S. are diagnosed with Ewing’s sarcoma, a rare cancer of the bone or surrounding soft tissue, according to the National Institutes of Health.  In four counties in southwest Pennsylvania, 31 people were diagnosed with Ewing’s sarcoma from 2006 through 2017, according to state cancer data. That is a roughly 40% increase from the period from 1995 through 2005, when 22 people in the same area were diagnosed, according to state data. Residents point to two additional cases in 2018. Most troubling to many local residents is that the six cases in Washington County since 2008 occurred in one school district.

Other communities are studying potential health risks of fracking. In October 2019, Colorado regulators said they would tighten regulation of drilling after a state-funded study found that people living within 2,000 feet of oil-and-gas wells could have, in worst-case scenarios, an elevated risk for infrequent, short-term health effects such as nosebleeds and headaches from emissions.

Evelyn Talbott, a professor of epidemiology at the University of Pittsburgh, said Pennsylvania investigators should look at residents’ potential exposures to chemicals and to radiation from natural-gas sites. She said they also should look at the sealed waste site of the defunct uranium-processing plant…Since Pennsylvania’s first Marcellus Shale well was drilled in Washington County in 2003, more than 1,800 wells have been fracked there. Compressor stations, processing plants and pipelines have followed. Some residents worry that pollutants such as benzene from air emissions or radium from wastewater could affect people’s health.

Imperfect Tools Used Imperfectly: 400 000 Malaria Deaths

According to a report, published on December 4th, 2019 by the World Health Organization,  there were 228 million cases of malaria in 2018, which resulted in 400,000 deaths. Most victims were young children in Africa. That is a far cry from targets set in 2015 for the near-elimination of malaria by 2030.  These targets depended on a $6 billion a year being poured into malaria-control efforts. Funding in recent years, however, has been about $3 billion a year. More money would surely help. But substantial gains can be made by doing things more efficiently—something at which malaria programmes have been dismal.

Stopping malaria relies on three things: insecticide-treated bed nets to prevent nocturnal mosquito bites; the spraying of homes with insecticides; and the treating of pregnant women and children with rounds of preventive medication. These are all “imperfect tools, often used imperfectly”, says Pedro Alonso, head of the malaria programme at the World Health Organisation. Countries usually deploy the same package of measures everywhere, even though infection rates and their seasonal patterns vary a lot between regions, and particularly between cities and the countryside. Transmission reaches a peak in the rainy season, when mosquitoes are abundant, so preventive mass-treatment of children then can make a huge difference. Regional variations are particularly pronounced in large countries like Nigeria—a place that, by itself, accounts for a quarter of the world’s malaria cases.

The typical approach of a malaria-control programme is to bombard a country with bed nets and then use whatever cash remains for sporadic rounds of preventive medication. But in many big cities, such as Dar es Salaam and Nairobi, cases are few and far between, so deploying nets there is a waste. Overspending on nets at the expense of other things happens partly because nets are easy to count—a feature that aid programmes are particularly fond of. Results which cannot be attributed directly to money a donor spends tend to fall further down that donor’s list of priorities. This kind of reasoning tips the scales, because foreign aid accounts for two-thirds of the money spent on malaria.

Ethical Mining 2020

Less than half of the world’s larger miners have released safety and environmental details about their mine-waste dams, showing the mixed success of investors’ demands for greater transparency after the deadly Brumadinho dam collapse in Brazil. In January, 2019, 270 people died following the collapse of a tailings dam owned by Brazil’s Vale SA. The incident prompted a coalition of investors who manage more than $13 trillion to ask 726 companies in the mining and oil-sands business to disclose information on their dams. Nearly 55% of companies hadn’t delivered as of November 2019. While some of the largest miners—including Vale, BHP , and Anglo American have disclosed their information, others have yet to do so. Investors are increasingly examining ethical issues when looking at mining.

Tailings, the waste material from extracting valuable minerals, are often held for decades behind dams that can be risky if they are poorly constructed, ill-maintained or filled with too much waste. Major failures of tailings dams have become more frequent as mining companies ramp up production to meet the world’s growing demand for commodities. Norilsk Nickel one of world’s most valuable miners with a market capitalization of roughly $43 billion, hasn’t publicly released details on its tailings dams. In 2016, heavy rainfall caused a Norilsk Nickel tailings dam in northern Russia to overflow, coloring a local river red. Miners of potash and phosphate—minerals used mainly in fertilizers—have been slow to disclose.

Another big company that has not released details is Canada-based Nutrient. Satellite images show two of the company’s six Saskatchewan mines are located a few miles from residential communities and one neighbors a bird-breeding area. A tailings pond at the company’s North Carolina phosphate mine is located next to the Pamlico River, which feeds into the state’s largest estuary.

In 2017, Israel Chemicals reported that the partial collapse of a subsidiary’s dike in Israel released 100,000 cubic meters of acidic wastewater that flowed into a nearby nature reserve. The wastewater resulted from the production of phosphate fertilizer.Vancouver-based Imperial Metals Corp.is tied to what is considered one of Canada’s worst environmental catastrophes. In 2014, a British Columbia dam owned by the company burst, sending some 25 million cubic meters of mining waste pouring into a pair of glacial lakes

Large Chinese miners such as Jiangxi Copper, Zijin Mining Group Co.  and Zhongjin Gold Corp. also haven’t shared information with the investor coalition. There are 8,869 documented tailings dams, of which 16% are within about half a mile of a residential area, school or hospital, according to research led by the School of University of Science and Technology in Beijing. Karen Hudson-Edwards, a mining specialist at Britain’s University of Exeter, said the actual number in China is estimated at around 12,000 dams and there is little transparency on tailings risk in the country. There have been at least 12 serious tailings-dam accidents in China since the 1960s, with one in 2008 killing 277 people, according to the World Information Service on Energy, a Netherlands-based nonprofit.

How to Lose Track of 250 barrels of Radioactive Waste — Los Alamos National Laboratory

The Triad National Security,*** the company in charge of Los Alamos National Laboratory’s (LANL) operations in 2018 lost track of 250 barrels of mixed hazardous waste on their way to the Waste Isolation Pilot Plant (WIPP) in Carlsbad. Mixed waste contains low-level radioactive waste and other hazardous materials. Failing to track such a high volume of waste is an egregious error that falls in line with the lab’s long history of serious missteps.  “The fact that LANL has mischaracterized, misplaced, mis-inventoried — or whatever — 250 barrels of waste is pretty astounding,” said Jay Coghlan, executive director of Nuclear Watch New Mexico.

Still, Triad has committed less than a tenth of the violations that its predecessor, Los Alamos National Security LLC, used to average in a given year.  A disastrous “kitty litter” incident happened under Los Alamos National Security, in which a waste barrel was packaged in error with a volatile blend of organic cat litter and nitrate salts, causing the container to burst and leak radiation at the Southern New Mexico storage site. WIPP closed for almost three years, and the cleanup cost about $2 billion.

***Triad is a public service oriented, national security science organization equally owned by its three founding members: Battelle Memorial Institute (Battelle), The Texas A&M University System (TAMUS), and The Regents of the University of California (UC).

Denizen Nuclear Waste: the Orchid Island

Several members of the Tao Aboriginal community in Taiwan reiterated their decades-long demand that the government remove nuclear waste from Taitung County’s Orchid Island saying that they would not accept the NT$2.55 billion (US$83.57 million) in compensation.  Since construction of a storage site was finished in 1982, more then 100,000 barrels of low-level radioactive waste have been transported from nuclear power plants on Taiwan proper to the outlying island, without obtaining residents’ consent in advance….  [According to the community], the government should establish a platform to discuss how to handle the nuclear waste and related compensation, while also continuing to reveal the storage site’s buried history

The Jihadist Mafia: Controlling the Gold of Sahel

Burkina Faso is struggling to contain a fast-growing jihadist insurgency. Along with Mali and Niger, it has become the main front line against terrorists in the Sahel, a dry strip of land that runs along the edge of the Sahara. This year alone the conflict has killed more than 1,600 people and forced half a million from their homes in Burkina Faso….A worrying new trend is a battle by jihadists and other armed groups to take control of the region’s gold rush.

Although gold has long been mined in the region…it has boomed in recent years with the discovery of shallow deposits that stretch from Sudan to Mauritania. International mining companies have invested as much as $5bn in west African production over the past decade, but the rush has also lured hundreds of thousands of unsophisticated “artisanal” miners. The International Crisis Group (ICG), an NGO, reckons that more than 2m people are involved in small-scale mining in Burkina Faso, Mali and Niger. In total they dig up 40-95 tonnes of gold a year, worth some $1.9bn-4.5bn.

Artisanal Mining’s Claustrophobic Conditions

This rush—in a region where states are already weak and unable to provide security—has sucked in a variety of armed groups and jihadists, including the likes of Ansar Dine and Islamic State in the Greater Sahara…The jihadists probably have direct control of fewer than ten mines…But they have influence over many more. In some areas artisanal miners are forced to pay “taxes” to the jihadists. In others, such as Burkina Faso’s Soum province, the miners hire jihadists to provide security… Other armed groups such as ethnic militias are also in on the bonanza and collect cash to guard mines. International mining firms may also be funding the jihadists by paying ransoms for abducted employees or “protection” money to keep mining, according to a study published by the OECD, a club of mostly rich countries.

For the moment much of Burkina Faso’s artisanal production is sneaked into Togo… Togo does not produce much gold domestically but it sent more than 12 tonnes of gold to Dubai in 2016. Gold is also taken out of the Sahel through major airports in hand luggage.

How to Engineer Bacteria to Search for Underground Chemical Weapons: DARPA

U.S. military researchers asked in 2019 two companies to develop new kinds of biological sensors that can detect underground disturbances or the presence of buried chemicals or weapons.

Officials of the U.S. Defense Advanced Research Projects Agency (DARPA) in Arlington, Va., are looking to Raytheon BBN Technologies, and Signature Science, for the BioReporters for Subterranean Surveillance program.  This project seeks to use indigenous and engineered organisms to sense changes of interest to military commanders in natural and built environments. Raytheon BBN and Signature Science won separate $1.6 million contracts for the Subterranean Surveillance progam.

The two companies will perform laboratory research and proof-of-concept demonstrations of biological sensing systems in well- controlled field tests that take advantage of recent advances in microbial science and synthetic biology to develop biological sensors, signal transducers, and reporters that can reveal subterranean phenomena at a distance.  Bio Reporters should be able to sense a phenomenon at least one meter below the surface, propagate a signal to the surface within seven days, and be continuously detectable on the surface at a distance of 10 meters over the subsequent seven days.

DARPA researchers want Raytheon BBN and Signature Science experts to take advantage of the extensive biological networks that exist underground to monitor large areas to increase the military’s ability to detect subterranean events without the need for precise coordinates.

Excerpts from John Keller, Researchers eye new biological sensors to to detect underground objects like buried chemicals and weapons, https://www.militaryaerospace.com,  Nov. 6, 2019

In more detail  Signature Science and its partner, the Texas A&M University Center for Phage Technology, aim to leverage modern and synthetic phage biology and the straightforward molecular genetics of the harmless soil bacterium Bacillus subtilis to generate a new platform to recognize and report on specific chemical threats underground. The Spore-Phage Amplified Detection (SPADe) method, potentially extensible to explosives, radiation or physical disturbance sensing, seeks to substantially advance currently used techniques which rely heavily on manual soil testing. 

Scrubbing Sulfur Pollution

From January 2020, the United Nations International Maritime Organization (IMO) will ban ships from using fuels with a sulphur content above 0.5%, compared with 3.5% now.The rules herald the biggest leap in how ships are powered since they switched from burning coal to oil over a century ago, but vessels will still be allowed to use higher-sulphur fuel if fitted with cleaning devices called scrubbers.  Closed-loop scrubbers keep most of the water used for sulphur removal onboard for disposal at port. Open-loop systems, however, remove sulphur coming through a ship’s smokestack with water that can then be pumped overboard.

Years of studies have examined whether open-loop scrubbers introduce into waterways acidic sulphur harmful to marine life, cancer-causing hydrocarbons, nitrates leading to algal blooms and metals that impair organ function and cause birth defects.  The results have largely been inconclusive and the IMO itself has encouraged further study into the environmental impact of scrubbers.

The stated aim of the new IMO measures is to improve human health..  A study in the journal Nature last year found ship emissions with current sulphur levels caused about 400,000 premature deaths from lung cancer and cardiovascular disease as well as around 14 million childhood asthma cases every year.

Singapore and Fujairah in the United Arab Emirates have banned the use of open-loop scrubbers from the start of next year. China is also set to extend a ban on scrubber discharge to more coastal regions.

Rivers of Crude Oil: the poisoned land of Iraq

A biological remediation pilot project seeking to enhance nature’s own ability to clear up oil spills in Iraq’s conflict-affected areas has been launched in Kirkuk, Iraq…This UNEP initiative seeks to harness naturally occurring soil bacteria as a powerful natural ally to decontaminate poisoned land.  Over three years ago in summer 2016, the residents of Qayyarah—a small town of around 25,000 people, some 60 km south of Mosul—were caught in the line of fire as so-called Islamic State fighters torched nineteen nearby oil wells. So thick were the clouds of smoke, that people could not distinguish day from night for weeks in what infamously came to be known as the “Daesh winter”.  Rivers of crude oil flowed through Qayyarah’s streets and into seasonal wadis as oil wells spewed tens of thousands of barrels of oil relentlessly for months. The specter of an even worse environmental catastrophe was heightened as the oil slick migrated to less than three kilometers from the Tigris River, Iraq’s water lifeline.

Following an epic battle to control the oil fires that took nearly a year, North Oil Company, which manages the oil fields of northern Iraq, is currently collecting an estimated 20,000 tonnes of remaining oil waste in Qayyarah into around a dozen large pits.  Progress, however, has been slow and pools of heavy viscous oil remain on the doorsteps of entire neighborhoods and households, who complain about the impacts of noxious fumes on their children’s health.

“In some places, the layer of heavy oil is two to three meters thick, and long stretches of wadi channels are now effectively tarmac roads on which cars can be driven,” observed Mohammed Dawood, head of Qayarrah oil refinery’s environmental unit. Furthermore, Environment Ministry officials expressed concern that exceptionally heavy rains and flash floods of the 2018/19 winter season washed out oil from the holding pits into the Tigris River.

While oil production restarted in Qayyarah immediately after the conflict ended in June 2017, reaching currently an estimated 40,000 barrels per day, little has been done to clean up the conflict’s toxic aftermath… The UN Environment Programme in collaboration with the UN Assistance Mission in Iraq delivered a four-day hands-on training workshop on remediation of oil spills by the use of bacteria  in September 2019. “By adding nutrients from manure, bulking agents like wood chips and water, we are simply creating the ideal conditions for bacteria to thrive and speeding up the natural process of breaking down the oil,”

The Impact of Oil Spills on the Deep Sea: the Deepwater Horizon Oil Spill

The Louisiana University Marine Consortium (LUMCON) published in September 2019 a study on the Deepwater Horizon Oil Spill in Royal Society Open Science.  The BP’s Deepwater Horizon oil rig exploded in April 2010, killing 11 workers.  The subsequent cleanup and restoration had cost nearly $65 billion..but while while we can burn off and disperse oil on the surface, but we don’t have the technology to get rid of oil on the seafloor. So approximately 10 million gallons of it settled there….In 2017 , the The LUMCON surveyed the site surrounding the wreck of the rig, and another one 1,640 feet north. There were no giant isopods, glass sponges, or whip corals that would have jumped (metaphorically) at the chance to colonize the hard substrate of the rig, such as discarded sections of pipe…..But]  crabs were just about everywhere. The researchers were shocked by the sheer number of crustaceans and other arthropods that had colonized the spill site. According to rough estimates, Atlantic deep sea red crabs, red shrimp, and white caridean shrimp were nearly eight times more populous at the Deepwater site than at other spots in the Gulf. “Everywhere there were crabs just kicking up black plumes of mud, laden with oil,” Nunnally says. But abundance does not mean the site was recovering, or even friendly to life. Particularly eerie was the crab’s achingly slow movement. “Normally, they scatter when they see the ROV lights,” he says. But these crabs seemed unbothered, or unaware of the robot’s presence.

Crabs on the seabed of the Deepwater Horizon oil spill

The researchers hypothesize that degrading hydrocarbons are what’s luring unwitting crabs from the surrounding seafloor to the deep-sea equivalent of a toxic dump. “The chemical makeup of oil is similar to the oils naturally present on crustaceans,” Nunnally says. “They’re attracted to the oil site, but everything goes downhill for them once they’re in the area.” A similar kind of chemical confusion occurred at an oil spill in Buzzards Bay in New England in 2003, which attracted hordes of American lobsters. The researchers liken the death trap to the La Brea Tar Pits: Once lured in, the crabs lose their ability to leave. With no other species able to thrive in the area, the crabs have no food source—except each other. And as one might imagine, consuming the flesh of a toxin-riddled crab or starving to death in a deep-sea tar pit is sort of a lose/lose situation.

The crabs also looked anything but normal: some claws shrunken, some swollen, shriveled legs, a dusting of parasites. “There were deformities, but mostly things were missing,” Nunnally says. “You come in with eight legs and try to get away on four or five.” The researchers have yet to ascertain what specific toxins led to these maladies. The shrimp looked just as awful as the crabs. “They didn’t look like shrimp from other sites,” Nunnally says, adding that many of the small crustaceans had humps in their backs—tumors, perhaps.

The Fight Against Toxic Algae

Signs posted around the Grand Lake, Ohio read: “Danger: Avoid all contact with the water.”  When dangerously high levels of toxins from blue-green algae in Grand Lake, Ohiio were publicized in 2009, many residents and tourists stopped using the 13,000-acre lake in northwest Ohio. Hotel revenue and home values sank for several years as algae bloomed in the state’s largest inland lake.

Greenish water still laps at Grand Lake’s shores, but recent water samples show that the amount of algae-feeding nutrients entering the lake is down significantly. State, federal and private donations covered more than $10 million in projects aimed at improving water quality. More people are boating on the lake again. Grand Lake could now serve as an example for communities with algae problems across the nation, experts say.

Algal blooms are on the rise, from Lake Erie to the Florida Everglades. In August 2019, the Environmental Protection Agency listed algae-related beach closures or health advisories in 23 states, and it said other blooms may not have been reported. In 2010, the EPA found that 20% of 50,000 lakes surveyed had been affected by phosphorous and nitrogen pollution, which feeds algae.e  Cleaning up bodies of water choked with toxic algae has proved difficult. The project to repair Grand Lake, once one of the most polluted by algae in the nation, is one of the clearest successes. It shows cleanup is possible, but also expensive and time-consuming.

“It’s not restored yet, but it’s on the road to recovery,” said Stephen Jacquemin, an associate professor of biology at Wright State University-Lake Campus in Celina.  Beginning in 2012, wetlands areas were built around the lake, which was hand dug in the 1830s. The thick stands of bulrushes and other plants have reduced phosphorous and nitrogen levels in water entering the wetlands before reaching the lake by as much as 90%, Dr. Jacquemin said.  Three wetland areas, which cost a total of about $6 million to build, are constructed as a series of interconnected pools that allow particulates to settle out and plants and microbes to remove nutrients.

 The state’s Department of Natural Resources has also dredged the lake bottom to remove nutrient-loaded sediment, and tried to clean up one of Grand Lake’s beaches near St. Marys by building a rock jetty and installing aerators and a curtain to filter water. Recent water tests there showed levels below 6 parts per billion of the toxin microcystin, under Ohio’s threshold of 20 parts per billion for avoiding contact with water.

The Truth About Forest Fires

BBC has used satellite data to assess the severity of fires in Brazil, Indonesia, Siberia and Central Africa.  It has concluded that although fires in 2019 have wrought significant damage to the environment, they have been worse in the past.   More than 35,000 fires have been detected so far in 2019 in East Asia  spreading smoky haze to Malaysia, Singapore, the south of Thailand and the Philippines, causing a significant deterioration in air quality.  But this is substantially fewer than many other years including those, such as 2015, exacerbated by the El Nino effect which brought unusually dry weather.

Haze Pollution

In Indonesia, peatland is set alight by corporations and small-scale farmers to clear land for palm oil, pulp and paper plantations, and can spread into protected forested areas.  The problem has accelerated in recent years as more land has been cleared for expanding plantations for the lucrative palm oil trade.  Old palm trees on plantations that no longer bear fruit are often set on fire to be replaced by younger ones.

The number of recorded fires in Brazil rose significantly in 2019, but there were more in most years in the period 2002 to 2010.  There is a similar pattern for other areas of Brazilian forestry that are not part of the Amazon basin.  For 2019, we have data up to the end of August, and the overall area burnt for those eight months is 45,000 sq km. This has already surpassed all the area burnt in 2018, but appears unlikely to reach the peaks seen in the previous decade… “Fire signals an end of the deforestation process,” says Dr Michelle Kalamandeen, a tropical ecologist on the Amazon rainforest.  “Those large giant rainforest trees that we often associate with the Amazon are chopped down, left to dry and then fire is used as a tool for clearing the land to prepare for pasture, crops or even illegal mining.”

The environmental campaign group Greenpeace has called the fires that have engulfed the Russian region of Siberia this year one of the worst outbreaks this century.  The cloud of smoke generated was reported to have been the size of all the European Union countries combined.  Forest fires in Siberia are common in the summer, but record-breaking temperatures and strong winds have made the situation particularly bad.  Russia’s Federal Forestry Agency says more than 10 million hectares (100,000 sq km) have been affected since the start of 2019, already exceeding the total of 8.6 million for the whole of 2018…. Drawing on data for the number of fires, it is clear that there have been other bad years, notably in 2003.

Nasa satellites have identified thousands of fires in Angola, Zambia and DR Congo.However, these have not reached record levels.  “I don’t think there’s any evidence that the fires we’re seeing in Africa are worse than we’ve seen in recent years,” Denis McClean, of the UN Disaster Risk Reduction agency, told the BBC.  According to data analysed by Global Forest Watch, fires in DR Congo and Zambia are just above average for the season but have been higher in past years.  In Angola, however, fires have been reported at close to record levels this year.

Some have drawn comparisons with the situation in the Amazon, but the fires in sub-Saharan Africa are different.  Take DR Congo – most fires are being recorded in settled parts of the country’s southern, drier forest and savannah areas, and so far not in tropical rainforest.  Experts say it is difficult to know what is causing these fires, which are seasonal. Many are likely to be on grassland, woodland or savannah in poor farming communities.  “Fires are very important landscape management tools and are used to clear land for planting crops,” says Lauren Williams, a specialist in Central and West African forests at the World Resources Institute.

Modernize or Die: Bio-Engineered Food

China is betting that CRISP technology*can transform the country’s food supply.  China also expanded its efforts beyond its borders in 2017, when the state-owned company ChemChina bought Switzerland-based Syngenta—one of the world’s four largest agribusinesses, which has a large R&D team working with CRISPR—for $43 billion. That was the most China has ever spent on acquiring a foreign company, and it created an intimate relationship between government, industry, and academia—a “sort of a ménage à trois” that ultimately could funnel intellectual property from university labs into the company, says plant geneticist Zachary Lippman of Cold Spring Harbor Laboratory in New York.

Chinese leaders “want to strategically invest in genome editing, and [by that] I mean, catch up,” says Zhang Bei, who heads a team of 50 scientists at the Syngenta Beijing Innovation Center…China may one day need CRISPR-modified plants to provide enough food for its massive population….    China needs to resolve how it will regulate CRISPR-engineered crops—a divisive issue in many countries. In a 2018 decision that rocked big agriculture, a European court ruled that such crops are genetically modified organisms (GMOs) that need strict regulation. In contrast, the U.S. Department of Agriculture (USDA) exempts genome-edited plants from regulations covering GMOs as long as they were produced not by transferring DNA from other species, but by inducing mutations that could have occurred naturally or through conventional breeding.  Chinese consumers are wary of GM food. The country strictly limits the import of GM crops, and the only GM food it grows are papayas for domestic consumption. But for CRISPR, many plant researchers around assume China will follow in the United States’s footsteps…

For Corteva, Syngenta, and the other two big ag companies—BASF and Bayer (which acquired Monsanto last year)—the long game is to use CRISPR to develop better versions of their serious moneymakers, the “elite” varieties of a wide range of crops that have big commercial markets. They sell dozens of kinds of elite corn seeds—for example, inbred strains that consistently have high yields or reliable resistance to herbicides. Creating the genetic purity needed for an elite variety typically takes traditional breeding of many generations of plants, and CRISPR is seen as the cleanest way to improve them quickly. The earlier methods of engineering a plant can lead to unwanted genomic changes that must be laboriously culled…

Syngenta sees CRISPR-modified corn as a big opportunity in China, which grows more hectares of corn than any other crop. Yields per hectare are only 60% of those in the United States because corn ear worms often weaken Chinese crops. A fungus thrives in the weakened plants, producing a toxin that makes the resultant ears unfit for animal feed. As a result, China must import a great deal of corn. (According to USDA, 82% of U.S.-grown corn has been engineered to have a bacterial gene that makes it resistant to ear worms.)…“Syngenta is putting a lot of emphasis to grow in China to become the leading seed company. The China market as a whole, if it modernizes as the U.S. has modernized, can be as big as the U.S. market.”

Jon Cohen, To feed its 1.4 billion, China bets big on genome editing of crops, Science Magazine, Aug. 2, 2019

* Genome editing (also called gene editing) is a group of technologies that give scientists the ability to change an organism’s DNA. These technologies allow genetic material to be added, removed, or altered at particular locations in the genome. Several approaches to genome editing have been developed. A recent one is known as CRISPR-Cas9.

The Rolls Royce Nuclear Reactor

Small modular nuclear  reactors (SMRs) are relatively small and flexible: they have a power capacity of up to 300 MW(e) and their output can fluctuate in line with demand. This makes them particularly attractive for remote regions with less developed grids, but also for use as a complement to renewables and for non-electric applications of nuclear power. SMRs can be manufactured and then shipped and installed on site, so they are expected to be more affordable to build.

The Rolls Royce SMR is small enough to be transported by truck.

Globally, there are about 50 SMR designs and concepts at different stages of development. Three SMR plants are in advanced stages of construction or commissioning in Argentina, China and Russia, which are all scheduled to start operation between 2019 and 2022…Some SMR designs have features that could reduce the tasks associated with spent fuel management. Power plants based on these designs require less frequent refuelling, every 3 to 7 years, in comparison to between 1 and 2 years for conventional plants, and some are even designed to operate for up to 30 years without refuelling. Nevertheless, even in such cases, there will be some spent fuel left, which will have to be properly managed.

Who Owns Your Voice? Grabbing Biometric Data

Increasingly sophisticated technology that detects nuances in sound inaudible to humans is capturing clues about people’s likely locations, medical conditions and even physical features.Law-enforcement agencies are turning to those clues from the human voice to help sketch the faces of suspects. Banks are using them to catch scammers trying to imitate their customers on the phone, and doctors are using such data to detect the onset of dementia or depression.  That has… raised fresh privacy concerns, as consumers’ biometric data is harnessed in novel ways.

“People have known that voice carries information for centuries,” said Rita Singh, a voice and machine-learning researcher at Carnegie Mellon University who receives funding from the Department of Homeland Security…Ms. Singh measures dozens of voice-quality features—such as raspiness or tremor—that relate to the inside of a person’s vocal tract and how an individual voice is produced. She detects so-called microvolumes of air that help create the sound waves that make up the human voice. The way they resonate in the vocal tract, along with other voice characteristics, provides clues on a person’s skull structure, height, weight and physical surroundings, she said.

Nuance’s voice-biometric and recognition software is designed to detect the gender, age and linguistic background of callers and whether a voice is synthetic or recorded. It helped one bank determine that a single person was responsible for tens of millions of dollars of theft, or 18% of the fraud the firm encountered in a year, said Brett Beranek, general manager of Nuance’s security and biometrics business.

Audio data from customer-service calls is also combined with information on how consumers typically interact with mobile apps and devices, said Howard Edelstein, chairman of behavioral biometric company Biocatch. The company can detect the cadence and pressure of swipes and taps on a smartphone.  How a person holds a smartphone gives clues about their age, for example, allowing a financial firm to compare the age of the normal account user to the age of the caller…

If such data collected by a company were improperly sold or hacked, some fear recovering from identity theft could be even harder because physical features are innate and irreplaceable.

Where to Go? 1 Million Tons Radioactive Water at Fukushima

In August 2019, Tepco projected that storage of radioactive water at the Fukushima nuclear plant would reach full capacity by around summer 2022 even after the expansion — the first time it has issued such a precise estimate.  According to Tepco, the Fukushima No. 1 plant had 960 massive tanks containing 1.15 million tons of treated water as of July 18, 2019. Water that has touched the highly radioactive melted fuel debris has been cleaned up through water treatment machines and is stored in the tanks, but the high-tech treatment machines are able to remove most radionuclides except tritium. The plant currently sees an increase of contaminated water by 170 tons a day, Tepco says.

Releasing tritium-tainted water into the sea in a controlled manner is common practice at nuclear power plants around the world, and it was generally considered the most viable option as it could be done quickly and would cost the least.  The head of the Nuclear Regulation Authority, Toyoshi Fuketa, has long said that releasing the treated water into the sea is the most reasonable option, but people in Fukushima, especially fishermen, fear it will damage the region’s reputation.

Addressing those concerns, the government panel, launched in November 2016, has been looking for the best option in terms of guarding against reputational damage. Injecting it into the ground, discharging it as steam or hydrogen, or solidification followed by underground burial have all been on the table. Under the current plan, Tepco is set to increase the tank space to store 1.37 million tons of water a total, but estimates show that will only last until summer 2022.  But the more space it creates, the bigger the decommissioning headache becomes.

Forest Fires in Africa Feed the Amazon Rainforest

The world’s largest rainforest and a crucial store of carbon dioxide gets most of its phosphorous, an important nutrient, from an unexpected source: fires in Africa.  Strange as it may seem, we thought that the Amazon got much of its phosphorus from dust whipped up from the Sahara Desert and transported across the Atlantic on the wind.

Cassandra Gaston at the University of Miami, US, and her colleagues had set out to quantify the effect of the phosphorous in Saharan dust on the Amazon’s growth. To do this, they collected and analysed particles caught in filters from a hilltop in French Guiana, at the northern edge of the Amazon Basin. But at the same time, they used satellites to track smoke from fires in Africa — both people burning wood and natural forest fires — drifting Westwards across the ocean. It turned out that the arrival of patches of smoke coincided with high levels of phosphorous being detected in the filters.  Gaston and her team then estimated how much of the phosphorus deposited on the Amazon Basin comes from African biomass burning. They found that, in Spring, smoke from the fires was responsible for most of the nutrient entering the Amazon Basin. …The findings suggest that people burning wood and other materials in Africa might have an impact on how much the Amazon grows and therefore how much carbon it stores in future.

From Streets into Drains into Seas: Cigarette Butts

Cigarette butts, the most littered items in the world, are posing an intractable trash problem for regulators and tobacco companies: Throwing them on the ground is a firmly entrenched habit for many smokers.  Regulators are taking a tougher stance on cigarette filter pollution amid concerns about the environmental impact of single-use plastic. Butts for decades have been made from cellulose acetate, a form of plastic, which takes years to break down. Studies show that butts—which often wash from sidewalks into drains and then waterways—can be toxic to fish.

About 65% of cigarettes smoked in the U.S. are littered, according to Keep America Beautiful, a nonprofit whose cigarette litter prevention program is funded by the tobacco industry.  “That whole habit is so ingrained it becomes part of the ritual of taking the cigarette out of the pack, lighting it, smoking it, putting it on the ground,” said Christopher Proctor, chief scientific officer at British American Tobacco (BAT), whose cigarette brands include Kent, Newport and Camel. “Changing ingrained behavior is a really difficult thing to do.”

The European Union in May adopted new rules under which members must pass laws within two years requiring tobacco companies to fund the cleanup of filter litter as part of a broader crackdown on single-use plastics. A bill proposing banning filters has made its way through the California Senate and will be heard by the lower house next year.  In response, BAT and Japan Tobacco Inc. are testing biodegradable filters, while Philip Morris International Inc. is assessing the appetite for portable ashtrays. Companies also are tapping behavioral psychologists to understand what propels smokers to litter, hoping to forestall stricter regulation…

he World Health Organization says that when filters do break down they leach out some of the 7,000 chemicals contained in cigarettes, many of which are environmentally toxic.

What 200 Million Irradiated Mosquitoes Can Do

In July 2019, a combination of the nuclear sterile insect technique (SIT) with the incompatible insect technique (IIT) has led to the successful suppression of mosquito populations, a promising step in the control of mosquitoes that carry dengue, the Zika virus and many other devastating diseases. The results of the recent pilot trial in Guangzhou, China, carried out with the support of the IAEA in cooperation with the Food and Agriculture Organization of the United Nations (FAO), were published in Nature on 17 July 2019.

SIT is an environmentally-friendly insect pest control method involving the mass-rearing and sterilization of a target pest using radiation, followed by the systematic area-wide release of sterile males by air over defined areas. The sterile males mate with wild females, resulting in no offspring and a declining pest population over time. IIT involves exposing the mosquitoes to the Wolbachia bacteria. The bacteria partially sterilizes the mosquitoes, which means less radiation is needed for complete sterilization. This in turn better preserves the sterilized males’ competitiveness for mating.

The main obstacle in scaling up the use of SIT against various species of mosquitoes has been overcoming several technical challenges with producing and releasing enough sterile males to overwhelm the wild population. 

For example, the researchers used racks to rear over 500 000 mosquitoes per week that were constructed based on models developed at the Joint FAO/IAEA Division’s laboratories near Vienna, Austria. A specialized irradiator for treating batches of 150 000 mosquito pupae was also developed and validated with close collaboration between the Joint FAO/IAEA Division and the researchers…The results of this pilot trial, using SIT in combination with the IIT, demonstrate the successful near-elimination of field populations of the world’s most invasive mosquito species, Aedes albopictus (Asian tiger mosquito). The two-year trial (2016-2017) covered a 32.5-hectare area on two relatively isolated islands in the Pearl River in Guangzhou. It involved the release of about 200 million irradiated mass-reared adult male mosquitoes exposed to Wolbachia bacteria

Experts in China plan to test the technology in larger urban areas in the near future using sterile male mosquitoes from a mass-rearing facility in Guangzhou, said Zhiyong Xi, Director of Sun Yat-sen University-Michigan State University’s Joint Center of Vector Control for Tropical Diseases and Professor at Michigan State University in the United States

Anti-Nuclear Protests in India

Agitations against the Kudankulam nuclear plant broke out in June 2019.  Villages around the contentious reactors moved a resolution to put a stop to the government’s plans to construct an Away From Reactor (AFR) facility on the premises of the nuclear power plant.  The AFR is a storage unit meant to store spent fuel generated at the two nuclear plants in Kudankulam… While resolutions passed at four villages –  Kavalkinar, Vadakankulam, Perumanal  and Kudankulam  were recorded by district authorities, a similar move in the village of Vijayapathi was stopped. The decision led to protests in the village and was forcefully dispersed by the police. …

A public hearing regarding the AFR scheduled for July 10, 2019 was recently postponed indefinitely. A look at the circular shows that only two villages were invited – Kudankulam and Vijayapathi. Activists allege that this was an intentional attempt to shut down dissent against the proposed facility. 

The resolutions included – opposition to collection of nuclear waste in Kudankulam, demand to stop construction of an AFR facility and demand to permanently shut down the plant. Opposition parties and activists had urged the Centre to come out with a detailed plan for setting up a permanent deep geological repository and drop the plan of a proposed Away From Reactor facility.   “This entire exercise is meant to create storage for spent fuel and an AFR is only a temporary solution till the government finds land to build a deep geological repository,” explains Sundarrajan. “But across the country, no state is ready to risk giving land for permanent disposal of nuclear waste. So, residents fear that this will used as an excuse by the government to make the AFR a permanent storage space.”

Humans as Lab Rats: Weaponizing Ticks

In July 2019, the US House of Representatives added an unusual amendment to the 2020 U.S. defense budget: a requirement that the Department of Defense reveal details of any biological warfare research it did involving ticks during the Cold War. The requirement stems from allegations that Lyme disease was actually a biowarfare experiment accidentally released into the wild.  The amendment was added to the defense budget by New Jersey Congressman Christopher Smith. It calls on the U.S. government to “conduct a review of whether the Department of Defense experimented with ticks and other insects regarding use as a biological weapon between the years of 1950 and 1975.”

If there was any sort of research the Pentagon Inspector General “must provide the House and Senate Armed Services committees with a report on the experiments’ scope and ‘whether any ticks or insects used in such experiments were released outside of any laboratory by accident or experiment design.’”

The call for information comes after the publication of the book Bitten: The Secret History of Lyme Disease and Biological Weapons. A major allegation in the book is that Willy Burgdorfer, the discoverer of the bacterium that causes Lyme Disease, claimed that the disease was the result of a biological weapons program that went awry. Burgdorfer himself was involved in biological warfare programs that involved using blood-sucking insects, including fleas, ticks, and mosquitoes, as vectors for the transmission of human diseases.

Weaponizing bugs isn’t a completely novel idea. Imperial Japan weaponized insects, typically fleas infected with plague and cholera, where they were used against the civilian population in China. The Japanese military organization responsible for the research, Unit 731, was later rounded up by the U.S. military after the war.  Despite committing serious, egregious crimes against humanity, including vivisection, members of the unit were only lightly punished by the Allies, reportedly in exchange for research data.

Lyme Disease affects approximately 30,000 people a year, primarily in the northeastern United States. The book alleges biowarfare research involving ticks took place at Fort Detrick, Maryland, and Plum Island, New York—both areas where CDC maps note the disease is very prevalent, but the CDC itself does not have an opinion on the allegation.

Not Sharing, even a Glass of Water: the Water Crisis in India

The southern city of Chennai—India’s fifth largest with a population of around 10 million—has been meeting only two-thirds of its water needs for weeks, the product of years of drought and decades of failure to manage the region’s water resources.   Residents have been scrambling around the clock to get water—spending hours chasing government tankers or paying private companies to deliver water.  Recent light rains broke a 200-day streak without rain. But the first month of India’s annual monsoon brought one-third less rain than the 50-year average, the driest June in five years, according to the India Meteorological Department.

The acute water shortage in one of India’s largest cities has been building for decades through a mix of population growth, poor planning and increasingly erratic monsoon rains….

The situation in Chennai reflects a larger water crisis spreading across India. Half the country’s population—600 million people—live in areas where water resources are highly or extremely stressed. About 100 million people living in 21 of India’s biggest cities may see their groundwater exhausted by the end of next year, according to a 2018 study by NITI Aayog, an Indian government policy think tank.  By 2030, demand for water will be double the country’s supply, the report said. And the impact will go far beyond the areas actually affected by water shortages: Almost one-third of the country’s agricultural output comes from areas most affected by water shortages…

The scarcity has led to clashes between neighbors. “No one is ready to share even a glass of water,” she said.

How to Detect Nuclear Terrorism in Big Cities

According to DARPA, terrorist attacks involving the use of proliferated radiological and special nuclear materials pose a potential threat to U.S. citizens and servicemembers. Early detection of such materials and devices made from them is a critical part of the U.S. strategy to prevent attacks. Lower-cost and more sensitive detectors, along with innovative deployment strategies, could significantly enhance detection and deterrence of attack.

The SIGMA program aims to revolutionize detection and deterrent capabilities for countering nuclear terrorism. A key component of SIGMA thus involves developing novel approaches to achieve low-cost, high-efficiency, packaged radiation detectors with spectroscopic gamma and neutron sensing capability. The program will seek to leverage existing infrastructure to help enable these next-generation detectors and their deployment in order to demonstrate game-changing detection and deterrent systems.

The Defense Advanced Research Projects Agency fielded a sensor network to trace radioactive and nuclear materials during the Indianapolis 500 event on June 30, 2019

When Plastic Reached the Himalayas: India’s War on Single-Use Plastics

The daily plastic waste generated by the average Indian—while much lower than the average American—climbed 69% between 2015 and 2018, according to government estimates. Across the country, dumps are overflowing and drains are clogging with plastic, while cows—considered sacred—are getting sick after eating packaging….To get a grip, India has instituted some of the world’s strictest rules on single-use plastic, forcing companies to collect packaging that is often left as litter.
 

Nonrecyclable packaging is a problem globally, but particularly acute in countries with poor waste management. Many Indian households lack regular collection services so they burn trash or dump it on the side of the road. Much of the waste ends up in waterways. Of plastic found in the world’s oceans, 90% is traced to 10 rivers, according to a 2017 study published in the journal Environmental Science & Technology. Eight of the rivers are in Asia and two flow through India.

Single-Serve Pouches

In emerging markets, products like shampoo and detergent are often sold in single-serve pouches similar to the ketchup packets that come with an order of fries. The resilient “multilayer” pouches protect against extreme temperatures and contamination, and, most important, are affordable for poor consumers. Single-serve packets make up over 80% of shampoo sales in India, Indonesia and the Philippines, according to Euromonitor….This type of packaging combines different types of plastic with materials like aluminum. That makes it nonrecyclable and of no interest to India’s waste pickers who trawl through trash looking for recyclables to sell.  Three years ago, India’s government said it would ban multilayer packaging by 2018, setting off alarm bells through the industry…

A consortium—including Nestlé, Pepsi and Mentos-maker Perfetti Van Melle SpA—tried for months to develop a recyclable alternative. After little success, they decided on a different approach.  Through street plays and workshops, the companies trained 1,500 waste pickers across eight cities to identify and collect multilayer packaging, paying them for what they brought in.  The pilot program amassed 680 metric tons of material in three months. In March 2018, New Delhi changed the law to allow the sale of multilayer packaging. The caveat is that companies must collect back the equivalent volume of what they sell and find other uses for it, like sending it to cement plants as fuel…

Despite such efforts, some government officials have accused companies of moving too slowly. E. Ravendiran of the Maharashtra Pollution Control Board says companies only swung into action after being threatened with bans or having to pay a deposit on multilayer packaging sold. Executives say the target of collecting 100% of multilayer plastic by 2020 is unrealistic and that details on how the rule will be implemented are scarce.

Hassan, a former waste picker who manages a small team of waste collectors in Bangalore, says pickers aren’t financially motivated to bend down hundreds of times to collect a kilogram of multilayer plastic from piles of mixed waste or just off the street. Saahas pays him 27 rupees (around 39 U.S. cents) for one kilogram of plastic bottles, compared with just 4 rupees for one kilogram of multilayer packaging, which is much harder to collect.

How to Prepare for Deadly Flu and Nuclear Fallout

Breakthroughs in the science of programmable gene expression inspired DARPA to establish the PReemptive Expression of Protective Alleles and Response Elements (PREPARE) program with the goal of delivering powerful new defenses against public health and national security threats. DARPA has now selected five teams to develop a range of new medical interventions that temporarily and reversibly modulate the expression of protective genes to guard against acute threats from influenza and ionizing radiation, which could be encountered naturally, occupationally, or through a national security event.

The program builds from the understanding that the human body has innate defenses against many types of health threats, but that the body does not always activate these defenses quickly or robustly enough to block the worst damage. To augment existing physiological responses, PREPARE technologies would provide a programmable capability to up- or down-regulate gene expression on demand, providing timely, scalable defenses that are proportional to anticipated threats. Service members and first responders could administer these interventions prior to threat exposure or therapeutically after exposure to mitigate the risk of harm or death.

Influenza: “Researchers working within the PREPARE program seek to improve rates of survival and recovery in catastrophic scenarios for which reliable and scalable countermeasures don’t currently exist,” said Dr. Renee Wegrzyn, the PREPARE program manager….Three PREPARE teams are pursuing multi-pronged approaches to influenza defense and treatment that use programmable gene modulators to boost the human body’s natural defenses against influenza and also weaken the virus’ ability to cause harm by directly neutralizing the viral genomes. If successful, their approaches would potentially protect against virtually all influenza strains — regardless of whether a virus is newly emergent or has developed drug resistance — and would provide near instantaneous immunity, in contrast to traditional vaccines. Additionally, the teams are designing their countermeasures so that they are simple to deliver — for example, as intranasal sprays — reducing the logistical challenge of protecting large numbers of people.A team led by DNARx LLC, under principal investigator Dr. Robert Debs, aims to develop a new DNA-encoded gene therapy that helps patients fight influenza by boosting the natural immune response and other protective functions of their nasal passages and lungs.

Radiation Hazard Symbol

Ionizing Gamma Radiation: Other PREPARE teams are pursuing treatments to protect the body from the effects of ionizing gamma radiation. In humans, radiation poisoning primarily affects stem cells in the blood and gut, yet existing treatments only help to regenerate blood cells, and only with limited effect. There is no possibility for prophylactic administration of these drugs, and most must be delivered immediately following radiation exposure to provide any benefit. There are no existing medical countermeasures for radiation damage to the gut
A team led by the University of California, San Francisco, under principal investigator Dr. Jonathan Weissman, also aims to develop gene therapies to enhance resilience against ionizing radiation. The team’s approach should result in an intravenous or orally available treatment that activates innate defenses in gut and blood stem cells for a period of several weeks.

How Venom from Spiders Kills Malaria Mosquitoes

In the 1980s, the village of Soumousso in Burkina Faso helped launch one of the most powerful weapons against malaria: insecticide-treated bed nets, which had early field trials there and went on to save millions of lives. But as mosquitoes developed resistance to widely used insecticides, the nets lost some of their power. Now, researchers are hoping the village can help make history again by testing a new countermeasure: a genetically modified (GM) fungus that kills malaria-carrying mosquitoes. In tests in a 600-square-meter structure in Soumousso called the MosquitoSphere—built like greenhouse but with mosquito netting instead of glass—the fungus eliminated 99% of the mosquitoes within a month, scientists report in the  magazine Science.

MosquitoSphere, Burkina Faso

The fungus also has clear advantages, however: It spares insects other than mosquitoes, and because it doesn’t survive long in sunlight, it’s unlikely to spread outside the building interiors where it would be applied.  Fungi naturally infect a variety of insects, consuming the host’s tissues in order to reproduce, and they have been used for decades to control a wide variety of crop pests….Researchers have tested dozens of different fungal strains against disease-carrying mosquitoes, but none was effective enough to pass muster. So researchers from the University of Maryland (UMD) in College Park and the Research Institute of Health Sciences & Centre Muraz in Bobo-Dioulasso, Burkina Faso, endowed a strain called M. pingshaense with a gene for a toxin isolated from spider venom that turns on when it contacts hemolymph, the insect version of blood. In the lab, the team showed its creation could kill mosquitoes faster and that just one or two spores could cause a lethal infection. 

Burkina Faso was a promising place for a field test: Unlike many countries in Africa, it has an established system to evaluate and approve the use of GM organisms. It also has one of the highest rates of malaria in the world, and insecticide-resistant mosquitoes are widespread. For those and other reasons, the U.S. National Institutes of Health funded the MosquitoSphere, which is specifically designed to test GM organisms.

Hunting Down Polluters: Repairing the Ozone Layer

CFC-11 is also known as trichlorofluoromethane, and is one of a number of chloroflurocarbon (CFC) chemicals that were initially developed as refrigerants during the 1930s. However, it took many decades for scientists to discover that when CFCs break down in the atmosphere, they release chlorine atoms that are able to rapidly destroy the ozone layer which protects us from ultraviolet light. A gaping hole in the ozone layer over Antarctica was discovered in the mid 1980s.  The international community agreed the Montreal Protocol in 1987, which banned most of the offending chemicals. Recent research suggests that the hole in the Northern Hemisphere could be fully fixed by the 2030s and Antarctica by the 2060s.

CFC-11 was the second most abundant CFCs and was initially seen to be declining as expected.However in 2018 a team of researchers monitoring the atmosphere found that the rate of decline had slowed by about 50% after 2012.  Further detective work in China by the Environmental Investigation Agency in 2018 seemed to indicate that the country was indeed the source. They found that the illegal chemical was used in the majority of the polyurethane insulation produced by firms they contacted.One seller of CFC-11 estimated that 70% of China’s domestic sales used the illegal gas. The reason was quite simple – CFC-11 is better quality and much cheaper than the alternatives.

This new paper seems to confirm beyond any reasonable doubt that some 40-60% of the increase in emissions is coming from provinces in eastern China.  Using what are termed “top-down” measurements from air monitoring stations in South Korea and Japan, the researchers were able to show that since 2012 CFC-11 has increased from production sites in eastern China.They calculated that there was a 110% rise in emissions from these parts of China for the years 2014-2017 compared to the period between 2008-2012.

“If we look at these extra emissions that we’ve identified from eastern China, it equates to about 35 million tonnes of CO2 being emitted into the atmosphere every year, that’s equivalent to about 10% of UK emissions, or similar to the whole of London.”  The Chinese say they have already started to clamp down on production by what they term “rogue manufacturers”. In  November 2018, several suspects were arrested in Henan province, in possession of 30 tonnes of CFC-11.

How Companies Buy Social License: the ExxonMobil Example

The Mobil Foundation sought to use its tax-exempt grants to shape American laws and regulations on issues ranging from the climate crisis to toxic chemicals – with the explicit goal of benefiting Mobil, documents obtained by the Guardian newspaper show.  Recipients of Mobil Foundation grants included Ivy League universities, branches of the National Academies and well-known civic organizations and environmental researchers.  Benefits for Mobil included – in the foundation’s words – funding “a counterpoint to so-called ‘public interest’ groups”, helping Mobil obtain “early access” to scientific research, and offering the oil giant’s executives a forum to “challenge the US Environmental Protection Agency (EPA) behind-the-scenes”….

A third page reveals Mobil Foundation’s efforts to expand its audience inside environmental circles via a grant for the Environmental Law Institute, a half-century-old organization offering environmental law research and education to lawyers and judges.  “Institute publications are widely read in the environmental community and are helpful in communicating industry’s concerns to such organizations,” the entry says. “Mobil Foundation grants will enhance environmental organizations’ views of Mobil, enable us to reach through ELI activities many groups that we do not communicate with, and enable Mobil to participate in their dialogue groups.”

The documents also show Mobil Foundation closely examining the work of individual researchers at dozens of colleges and universities as they made their funding decisions, listing ways that foundation grants would help shape research interests to benefit Mobil, help the company recruit future employees, or help combat environmental and safety regulations that Mobil considered costly.  “It should be a wake-up call for university leaders, because what it says is that fossil fuel funding is not free,” said Geoffrey Supran, a postdoctoral researcher at Harvard and MIT.  “When you take it, you pay with your university’s social license,” Supran said. “You pay by helping facilitate these companies’ political and public relations tactics.”

In some cases, the foundation described how volunteer-staffed not-for-profits had saved Mobil money by doing work that would have otherwise been performed by Mobil’s paid staff, like cleaning birds coated in oil following a Mobil spill.  In 1987, the International Bird Rescue Research Center’s “rapid response and assistance to Mobil’s West Coast pipeline at a spill in Lebec, CA not only defused a potential public relations problem”, Mobil Foundation said, “but saved substantial costs by not requiring our department to fly cross country to respond”.d of trustees at the Woods Hole Oceanographic Institution (recipient of listed donations totalling over $200,000 from Mobil) and a part of UN efforts to study climate change.

Wise ultimately co-authored two UN Intergovernmental Panel on Climate Change reports, serving as a lead author on one. One report chapter Wise co-authored prominently recommended, among other things, burning natural gas (an ExxonMobil product) instead of coal as a way to combat climate change.

Biodiversity and Respect for Human Rights

The instinctive response of many environmentalists  is to to fence off protected areas as rapidly and extensively as possible. That thought certainly dominates discussions of the Convention on Biological Diversity, the main relevant international treaty. An eight-year-old addendum to the pact calls for 17% of the world’s land surface and 10% of the ocean’s water column (that is, the water under 10% of the ocean’s surface) to be protected by 2020. Currently, those figures are 15% and 6%. Campaigners want the next set of targets, now under discussion, to aim for 30% by 2030—and even 50% by 2050. This last goal, biogeographers estimate, would preserve 85% of life’s richness in the long run.  As rallying cries go, “Nature needs half” has a ring to it, but not one that sounds so tuneful in the poor countries where much of the rhetorically required half will have to be found. Many people in such places already feel Cornered by Protected Areas.” (See also Biodiversity and Human Rights)

James Watson, chief scientist at the Wildlife Conservation Society (wcs), another American charity, has an additional worry about focusing on the fence-it-off approach. If you care about the presence of species rather than the absence of humans, he warns, “‘nature needs half’ could be a catastrophe—if you get the wrong half.” Many terrestrial protected areas are places that are mountainous or desert or both. Expanding them may not translate into saving more species. Moreover, in 2009 Lucas Joppa and Alexander Pfaff, both then at Duke University in North Carolina, showed that protected areas disproportionately occupy land that could well be fine even had it been left unprotected: agriculture-unfriendly slopes, areas remote from transport links or human settlements, and so on. Cordoning off more such places may have little practical effect.

 In the United States it is the underprotected southern Appalachians, in the south-east of the country, that harbour the main biodiversity hotspots. The largest patches of ring-fenced wilderness, however, sit in the spectacular but barren mountain ranges of the west and north-west. In Brazil, the world’s most speciose country, the principal hotspots are not, as might naively be assumed, in the vast expanse of the Amazon basin, but rather in the few remaining patches of Atlantic rainforest that hug the south-eastern coast.

Nor is speciosity the only consideration. So is risk-spreading. A team from the University of Queensland, in Australia, led by Ove Hoegh-Guldberg, has used a piece of financial mathematics called modern portfolio theory to select 50 coral reefs around the world as suitable, collectively, for preservation. Just as asset managers pick uncorrelated stocks and bonds in order to spread risk, Dr Hoegh-Guldberg and his colleagues picked reefs that have different exposures to rising water temperatures, wave damage from cyclones and so on. The resulting portfolio includes reefs in northern Sumatra and the southern Red Sea that have not previously registered on conservationists’ radar screens…

Another common finding—counterintuitive to those who take the “fence-it-all-off” approach—is that a mixed economy of conservation and exploitation can work. For example, rates of deforestation in a partly protected region of Peru, the Alto Mayo, declined by 78% between 2011 and 2017, even as coffee production increased from 20 tonnes a year to 500 tonnes.

Environmental groups can also draw on a growing body of academic research into the effective stewardship of particular species. For too long, says William Sutherland, of Cambridge University, conservationists have relied on gut feelings. Fed up with his fellow practitioners’ confident but unsubstantiated claims about their methods, and inspired by the idea of “evidence-based medicine”, he launched, in 2004, an online repository of relevant peer-reviewed literature called Conservation Evidence.  Today this repository contains more than 5,400 summaries of documented interventions. These are rated for effectiveness, certainty and harms. Want to conserve bird life threatened by farming, for example? The repository lists 27 interventions, ranging from leaving a mixture of seed for wild birds to peck (highly beneficial, based on 41 studies of various species in different countries) to marking bird nests during harvest (likely to be harmful or ineffective, based on a single study of lapwing in the Netherlands). The book version of their compendium, “What Works in Conservation”, runs to 662 pages. It has been downloaded 35,000 times.

How to Make Broken Ships Disappear: pollution

How do you make a 10,000-tonne container ship disappear? At Alang, a small town in Gujarat, on the western coast of India  is the world’s biggest ship-breaking town. Almost a third of all retired vessels—at least 200 each year—are sent to be broken up here, at over 100 different yards stretching along 10km of sand. The industry employs some 20,000 people, almost all men who migrate from the poorer states of India’s northern Hindi-speaking belt. Taxes paid by breakers generate huge sums for the state government. Yet it is a dangerous industry for its workers and a filthy one in environmental terms.

Of 744 ships that were pulled apart worldwide last year, 518 were dismantled on beaches. Only 226 were processed “off the beach” at industrial sites designed for the purpose, according to the Shipbreaking Platform, an ngo which campaigns against beach-breaking. The majority of big shipping firms use beaches, except a tiny few such as Hapag Lloyd of Germany and Boskalis of the Netherlands.

A typical operation involves a ship being beached at low tide. Once her fittings and other resaleable parts are removed, hundreds of workers with gas blowtorches clamber over the vessel’s hull, cutting it into huge steel blocks. These are then dropped onto the beach, where they are cut up again before being sold, then rerolled for use in construction.

Apart from the danger of dropping tens of tonnes of steel from a great height, the method is immensely polluting. A review in 2015 by Litehauz, a Danish marine environmental consultancy, found that in the process of scrapping a 10,000-tonne ship at least 120 tonnes of steel becomes molten and is lost in the sea. Levels of mercury and lead, as well as oil, in Alang’s water are at least 100 times higher than at other beaches. Workers must handle asbestos and dangerous chemicals. Accidents are common. Last year 14 workers died at Alang.Alang is just one of many ship-breaking centres in South Asia. Among the others are beaches in Bangladesh (where workers reportedly include children) and Pakistan. Last year the subcontinent recycled around 90% of the world’s ships by tonnage.

Ship-breaking is concentrated in the region for three reasons. Prices for scrap steel are higher than elsewhere (90% of a ship is typically steel), thanks to demand for rerolled steel for construction. Labour costs are lower than at yards in Europe, America or Turkey (workers at Alang make up to 800 rupees, or $11, per day, and usually less) and safety and environmental regulations are much weaker. Most sellers scrap their ships in South Asia because they get better prices for them.

 Shipowners, in particular Maersk, a Danish company which is the world’s biggest shipper, are preparing to comply with them…At the Baijnath Melaram shipyard a huge crane barge sits in the water next to a stretch of “impermeable” concrete. “We used to have to winch the blocks up the beach,” says Siddharth Jain, the firm’s business manager. Now, the crane lifts blocks of steel down from the ships directly to the concrete, so that they need never touch the sand. In contrast to the yards nearby, where men in simple work clothes and no safety goggles operate blowtorches, the workers scuttling around Baijnath Melaram wear boiler suits, face masks and helmets.

Blocks of steel from recycled ships

The changes are largely down to Maersk… Around 70 more are upgrading in order to meet standards set by the Hong Kong International Convention for the Safe and Environmentally Sound Recycling of Ships, an unratified treaty on ship recycling.  Maersk’s campaign is in response to new regulations in force since December 31st 2018 that require all European-flagged vessels to be recycled at shipyards approved by Brussels. Just over a third of the world’s ships fall in this category. Maersk, whose fleet is roughly 40% European-flagged, hopes that the best yards at Alang will be able to comply with the new rules. Two Indian yards have already been audited for the European certification; 11 more have applied. “If we sustain that momentum, in five, six or seven years all of Alang could be really responsible,” says John Kornerup Bang, Maersk’s sustainability chief.

But on January 30, 2019 the eu announced that the Indian yards audited will not make the list,… Ingvild Jenssen of the Shipbreaking Platform says that even Alang’s best yards are not clean enough. She argues that Maersk’s efforts merely “greenwash” a model that needs to change completely…. Not clean enough for Europe; but too expensive to compete with breakers in Bangladesh or Pakistan which have not changed at all. If that happens, the industry in Alang—and the jobs and revenue it generates—could disappear almost as quickly as the ships it dismantles.

Can’t Eat This! MicroPlastics Carrying Bacteria

The hard surface of waterborne plastic provides an ideal environment for the formation of biofilm by opportunistic microbial colonisers, and could facilitate a novel means of dispersal for microorganisms across coastal and marine environments. Biofilms that colonise the so-called ‘plastisphere’ could also be a reservoir for faecal indicator organisms (FIOs), such as Escherichia coli, or pathogenic bacteria such as species of Vibrio.

Nurdles on bathing beach

A study published in March 2019 looks into five public bathing beaches and quantifies their colonisation by E. coli and Vibrio spp. Nurdles [i.e., microplastics] were heterogeneously distributed along the high tide mark at all five beaches, and each beach contained nurdles that were colonised by E. coli and Vibrio spp. Knowledge of E. coli colonisation and persistence on nurdles should now be used to inform coastal managers about the additional risks associated with plastic debris.

A Swamp of Oil Pollution: Ogoniland

Status of Cleaning up Oil Pollution in Ogoniland, Nigeria:

According to the Civil Society Legislative Advocacy Centre (CISLAC), the clean-up of Ogoniland is bugged with identity crisis, procedures, processes and overheads. Perception of corruption, lack of transparency and accountability, complex decision making, internal crisis of choice between Ogoni and the Niger Delta….The United Nations Environment Programme (UNEP) released its Environmental Assessment of Ogoniland in August 2011 after series of protests of oil spillage in the community that culminated to the death of Ken Sarowiwa and eight others.  The report  made recommendations to the government, the oil and gas industry and communities to begin a comprehensive cleanup of Ogoniland, restore polluted environments and put an end to all forms of ongoing oil contamination in the region…

Pollution of soil by petroleum hydrocarbons in Ogoniland is extensive in land areas, sediments and swampland.  In 49 cases, UNEP observed hydrocarbons in soil at depths of at least 5 metres. At 41 sites, the hydrocarbon pollution has reached the groundwater at levels in excess of the Nigerian standards permitted by National Laws..

The Micro-Plastics Menance: Oceans

The IUCN report published in 2019 looked at primary microplastics – plastics that enter the oceans in the form of small particles, as opposed to larger plastic waste that degrades in the water – released from household and industrial products across seven geographical regions. Sources of primary microplastics include car tyres, synthetic textiles, marine coatings, road markings, personal care products, plastic pellets and city dust.  According to the report, between 15 and 31% of the estimated 9.5 m tonnes of plastic released into the oceans each year could be primary microplastics, almost two-thirds of which come from the washing of synthetic textiles and the abrasion of tyres while driving…Synthetic textiles are the main source of primary microplastics in Asia and tyres dominate in the Americas, Europe and Central Asia…. Synthetic clothes could be designed to shed fewer fibres, for example, and consumers can act by choosing natural fabrics over synthetic ones”

The World Health Organization is reviewing microplastics’ potential impact on human health after a study found plastic in 259 bottles of water from 11 different brands bought in nine countries. Microplastics have turned up in seafood, drinking water, beer, honey and sugar, according to studies, but the impact on human health is unclear.Research shows that ingesting microplastics can hurt the ability of planktonic organisms to feed and the ability of fish and marine worms to gain energy from food.  Pending bills in New York and California, if successful, would require labels on clothes made from more than 50% synthetic material to tell consumers that these shed plastic microfibers when washed.

Researchers also have zeroed in on how clothes are washed. Outdoor-apparel brand Patagonia found fabrics shed lots of microfibers on the first wash, but few in subsequent washes. That suggests pretreating garments before they are sold could potentially capture and recycle what otherwise goes down consumers’ drains.  It also found types of washing machines matter. Jackets washed in top-load washing machines shed seven times as many microfibers as front-loaders.

How Nuclear Technology Creates New Plants

Joining the FAO/IAEA coordinated research projects in the area of mutation breeding has led to the development of several barley mutant lines with improved yield and quality under Kuwait’s environmental conditions.  As arable land is limited to small areas, 95% of the country’s food and animal fodder is imported. Barley is a preferred crop for cultivation, because it is relatively drought tolerant and therefore one of the most suitable crops for an arid country like Kuwait. Having high yielding home grown crops is among the key objectives of the country’s agricultural programme to enhance food security.

Drought, salinity and diseases have historically limited staple crop productivity in Kuwait.   Mutation induction by radiation rapidly increases the genetic diversity necessary to produce new and improved varieties and is thus advantageous over traditional breeding…The best adaptable varieties were identified, and the seeds were subjected to induced mutation using gamma rays.

New mutant lines have been generated and they are now examined for drought and salinity tolerance. The selected mutant lines will be advanced, which then can be multiplied for planting. …One of the major challenges was explaining to farmers the safety of the new mutated barley lines developed. “When they heard that ‘nuclear techniques’ were used to create improved barely seeds, they got scared….

Plastics in Seas as New Tiny Ecosystems

The malign effect of floating plastic debris on seabirds, turtles and other sea creatures is well known. But, as Dr Mincer and Dr Amaral-Zettler have discovered, plastic debris also provides a new habitat for organisms small enough to take advantage of it.  The two researchers collected pieces of plastic from various sites in the North Atlantic. They then examined each using DNA analysis, and also an electron microscope, to see what was living on it. Lots of things were. Altogether, they discovered about 50 species of single-celled plant, animal and bacterial life. Each bit of debris was, in effect, a tiny ecosystem….Plastics are energy-rich substances, which is why many of them burn so readily. Any organism that could unlock and use that energy would do well….Less encouragingly, Dr Mincer and Dr Amaral-Zettler also found cholera-like bacteria in their tiny floating ecosystems. Both fish and seabirds act as vectors for cholera (the former bring it into human settlements when caught by fishermen, the latter when resting ashore or nesting), so anywhere that such creatures might pick up cholera bugs is something worth keeping an eye on.

The researchers paint an intriguing picture of the adaptability of nature, and provide another piece of the jigsaw that is the Anthropocene. Conservationists intent on preserving charismatic megafauna have reason to lament the spread of plastics through the ocean. But those interested in smaller critters have been given a whole, new sphere—the plastisphere—to study.

How to Kill One Million Fish: Murray-Darling

But it took a viral video posted on 8 January 2019 to drive home the ecological catastrophe that was unfolding in the Murray-Darling river system in Australia. In the footage, Rob McBride and Dick Arnold, identified as local residents, stand knee-deep among floating fish carcasses in the Darling River, near the town of Menindee. They scoff at authorities’ claims that the fish die-off is a result of the drought. Holding up an enormous, dead Murray cod, a freshwater predator he says is 100 years old, McBride says: “This has nothing to do with drought, this is a manmade disaster.” Arnold, sputtering with rage, adds: “You have to be bloody disgusted with yourselves, you politicians and cotton growers.”

Scientists say McBride probably overestimated the age of the fish. But they agree that the massive die-off was not the result of drought. “It’s about taking too much water upstream [to irrigate farms] so there is not enough for downstream users and the fish,” says Quentin Grafton, an economist specializing in water issues at Australian National University (ANU) in Canberra. The Australia Institute, a Canberra-based think tank, blamed “policy failure and mismanagement” in a 19 January 2019 report, but called drought a catalyst.

Excessive water use has left river flows too low to flush nutrients from farm runoff through the system, leading to large algal blooms, researchers say. A cold snap then killed the blooms, and bacteria feeding on the dead algae sucked oxygen out of the water,   This wasn’t supposed to happen. In 2012, the national government adopted the Murray-Darling Basin Plan, touted as a “historic” deal to ensure that enough water remained in the rivers to keep the ecosystem healthy even after farmers and households took their share.

In 2008, the federal government created the Murray-Darling Basin Authority to wrestle with the problem. In 2010, a study commissioned by the authority concluded that farmers and consumers would have to cut their use of river water by at least 3000 but preferably by 7600 gigaliters annually to ensure the health of the ecosystem. Farmers, who saw their livelihoods threatened, tossed the report into bonfires.  The final plan, adopted as national law in 2012, called for returning just 2750 gigaliters to the rivers, in part by buying water rights back from users. “It was a political compromise that has never been scientifically reviewed,” Williams says, adding that “climate change was never considered in the plan, which was a dreadful oversight.”..

Grafton says there are also suspicions of widespread water theft; up to 75% of the water taken by irrigators in the northern part of the system is not metered. Farmers are also now recapturing the runoff from irrigated fields that used to flow back into streams, and are increasing their use of ground water, leaving even less water in the system, says Mike Young, an environmental policy specialist at the University of Adelaide in Australia.

In February 2018, such issues prompted a group of 12 academics, including scientists and policy experts, to issue the Murray-Darling Declaration. It called for independent economic and scientific audits of completed and planned water recovery schemes to determine their effects on stream flows. The group, which included Williams and Grafton, also urged the creation of an independent, expert body to provide advice on basin water management. Young, who wasn’t on the declaration, wants to go further and give that body the power to manage the basin’s water, the way central banks manage a country’s money supply, using stream levels to determine weekly irrigation allocations and to set minimum flow levels for every river.

Caring for the Third Pole

The Tibetan Plateau and its surrounding mountains [the Himalayas], often termed the Third Pole, contain more ice than anywhere outside the Arctic and Antarctic. This region is also the source of the nine largest rivers in Asia, providing fresh water, food, and other ecosystem services to more than 1.5 billion people…In recent decades, air temperature at the Third Pole has warmed significantly faster than the global average…Meanwhile, intensive anthropogenic activities, such as overgrazing, deforestation, urbanization, and expansion of infrastructure projects such as construction of roads, dams, and electrical grids, are causing widespread landcover changes within the region.

Together, these changes are altering the Third Pole’s biogeochemical cycles and pushing the fragile ecosystem toward degradation and possible collapse, which would cause irreversible harm on a regional and global scale. To avoid this, all nations must meet the standards laid out in the Paris Agreement. At the regional level, we strongly urge the relevant nations (including Afghanistan, Bhutan, China, India, Kyrgyzstan, Myanmar, Nepal, Pakistan, and Tajikistan) to cooperate in addressing these impending threats through systematic changes to management policies. Rapid and unprecedented coordination will be necessary, including a regional cooperation treaty and formation of a cross-border biodiversity conservation plan for the Third Pole region. Meanwhile, any infrastructure projects undertaken must be environmentally sustainable, and a practicable grazing management policy should be adopted.

Planting Electronics in Brains

 An implantable brain device that literally melts away at a pre-determined rate minimizes injury to tissue normally associated with standard electrode implantation, according to research led by a team from the Perelman School of Medicine at the University of Pennsylvania. …Thin, flexible neural electrode arrays with fully bioresorbable construction based on patterned silicon nanomembranes (Si NMs) as the conducting component.

“Dissolvable silicon electronics offer an unprecedented opportunity to implant advanced monitoring systems that eliminate the risks, cost, and discomfort associated with surgery to extract current devices used for post-operative monitoring,” said senior co-author Brian Litt, MD,….“This study tested the usefulness of temporary, dissolvable monitoring systems capable of providing continuous streams of data for guiding medical care over predetermined periods of time — from days to months — before dissolving.”

The device is made of layers of silicon and molybdenum that can measure physiological characteristics and dissolve at a known rate, as determined by its thickness. For example, the team used the device to record brain waves in rats under anesthesia, as well as voltage fluctuations between neurons (EEGs), and induced epileptic spikes in intact live tissue. A separate experiment demonstrated a complex, multiplexed array made from these materials that could map rat-whisker sensing capabilities at high resolution.

These electrophysiological signals were recorded from devices placed at the surface of the brain cortex (the outer layer of tissue) and the inner space between the scalp and skull. Chronic measurements were made over a 30-day period, while acute experiments demonstrated device operations over three to four hours.

The type of neurophysiologic features measured by the new device are commonly used for diagnosing and treating such disorders as epilepsy, Parkinson’s disease, depression, chronic pain, and conditions of the peripheral nervous system. “….

This work was funded by the Defense Advanced Research Projects Agency, the Penn Medicine Neuroscience Center,  and others.

How to Stop the Chemical Wars of the Future

Stark illustrations of the dangers from chemical weapons can be seen in attacks using toxic industrial chemicals and sarin against civilians and combatants in Syria and toxic industrial chemicals in Iraq, as well as more targeted assassination operations in Malaysia and the United Kingdom, employing VX and novichok nerve agents, respectively. . With the parties to the Chemical Weapons Convention (CWC) convening a Review Conference to address such issues beginning 21 November 2018, we highlight important scientific aspects .

The Chemical Weapons Convention (CWC) is a multilateral treaty in effect since 1997 that proscribes the development, production, stockpiling, transfer, and use of chemical weapons “under any circumstances” and requires their destruction within a specified time period. The CWC allows the use of toxic chemicals for a range of industrial, agricultural, research, medical, pharmaceutical, or other peaceful purposes, including law enforcement, as long as the “types and quantities” of chemicals employed are “consistent with such purposes.” …The Organisation for the Prohibition of Chemical Weapons (OPCW), which is the implementing body of the CWC, comprises the 193 State Parties and a Technical Secretariat that provides technical assistance to States, routinely inspects relevant State and commercial industrial facilities, and monitors activities to ensure compliance. It was awarded the Nobel Peace Prize in 2013 for overseeing and facilitating the verified destruction of most of the declared chemical weapons stocks produced in the last century—to date totaling more than 96% (69,750 metric tons) of the declared stockpiles of chemical agents.

Although the CWC includes three schedules of toxic chemicals for the application of verification measures, the scope of the CWC is not constrained to these schedules but by its General Purpose Criterion (GPC), which prohibits misuse of toxic chemicals based on intent rather than on this limited list of chemicals.  [This GPC makes it possible to widen the authority of the OPCW. More, specifically issues to consider include]:

1) Riot control agents (RCAs). The CWC defines RCAs—such as tear gas and pepper spray—as “any chemical not listed” in one of its three schedules that can produce “rapidly in humans sensory irritation or disabling physical effects which disappear within a short time following termination of exposure.”…However, a recurring concern documented by the medical community and human rights monitors has been the widespread misuse of RCAs by police and security forces in excessive quantities, including in hospitals, prisons, homes, and automobiles, where targeted individuals cannot disperse. In such situations, serious injury or death can result from toxic properties of chemicals or from asphyxiation… [It is important to clarify] the nature and scope of “law enforcement” activities and develop guidance as to “types and quantities” of RCAs that can legitimately be used in such circumstances

2) Delivery systems… capable of delivering far greater amounts of RCAs (and potentially other toxic chemicals) over wider areas or more extended distances than current standard law enforcement delivery mechanisms, such as handheld sprays, grenades, and single launched projectiles. Such new systems include large-capacity spraying devices, automatic grenade launchers, multibarrel projectile launchers, large-caliber RCA projectiles, and unmanned ground or aerial vehicles capable of carrying spraying devices or projectile launchers. ..

3) Incapacitating chemical agent (ICA) weapons. Although the CWC permits use of appropriate types and quantities of RCAs for law enforcement, certain countries have conducted research into weapons employing other distinct toxic chemicals, so-called ICAs. Not separately defined under the CWC, ICAs can be considered as a range of toxic chemicals—only one of which [3-quinuclidinyl benzilate (BZ) and two of its immediate precursors] is currently scheduled—including anesthetics and other pharmaceutical chemicals that are purportedly intended to act on the body’s core biochemical and physiological systems, notably the central nervous system (CNS), to cause prolonged but nonpermanent disability. Such CNS-acting chemicals can produce unconsciousness, sedation, hallucination, incoherence, disorientation, or paralysis…An aerosolized mixture of two anesthetics—carfentanil and remifentanil—employed by Russian security forces to end the Moscow theatre siege of October 2002 caused the deaths of 125 of the 900 hostages

Other chemical production facilities (OCPFs) are chemical plants that do not currently produce, but are capable of manufacturing, chemical warfare agents or precursors. At present, a small fraction of declared OCPFs are selected for verification by the OPCW; the Review Conference should consider authorizing a substantial increase in OCPF inspections per year. …Biological and biologically mediated processes for production of discrete organic chemicals  Some products and processes used by the biomanufacturing industry are as relevant to the CWC as those used by other OCPF facilities  The OPCW should  build on the considerable progress made toward developing a network of designated laboratories for the analysis of biomedical and biological samples. Advances in other fields could also facilitate more effective evidence collection, for example, exploring the potential of unmanned aerial vehicles to support reconnaissance, detection, and chain of custody.

Eradicate Mosquitoes Forever: Gene Drives

The mosquitoes are being fitted with a piece of dna called a gene drive. Unlike the genes introduced into run-of-the-mill genetically modified organisms, gene drives do not just sit still once inserted into a chromosome. They actively spread themselves, thereby reaching more and more of the population with each generation. If their effect is damaging, they could in principle wipe out whole species.. If gene drives were to condemn to a similar fate the mosquitoes that spread malaria, a second of humankind’s great scourges might be consigned to history.

Gene drives can in principle be used against any creatures which reproduce sexually with short generations and aren’t too rooted to a single spot. The insects that spread leishmaniasis, Chagas disease, dengue fever, chikungunya, trypanosomiasis and Zika could all be potential targets. So could creatures which harm only humankind’s dominion, not people themselves. Biologists at the University of California, San Diego, have developed a gene-drive system for Drosophila suzukii, an Asian fruitfly which, as an invasive species, damages berry and fruit crops in America and Europe. Island Conservation, an international environmental ngo, thinks gene drives could offer a humane and effective way of reversing the damage done by invasive species such as rats and stoats to native ecosystems in New Zealand and Hawaii.

Such critics fear that the laudable aim of vastly reducing deaths from malaria—which the World Health Organisation puts at 445,000 a year, most of them children—will open the door to the use of gene drives for far less clear-cut benefits in ways that will entrench some interests, such as those of industrial farmers, at the expense of others. They also point to possible military applications: gene drives could in principle make creatures that used not to spread disease more dangerous… The ability to remove species by fiat—in effect, to get them to remove themselves—is, like the prospect of making new species from scratch, a power that goes beyond the past ambit of humankind.

Gene drives based on crispr-Cas9 could easily be engineered to target specific bits of the chromosome and insert themselves seamlessly into the gap, thus ensuring that every gamete gets a copy . By 2016, gene drives had been created in yeast, fruitflies and two species of mosquito. In work published in the journal Nature Biotechnology in September, Andrea Crisanti, Mr Burt and colleagues at Imperial showed that one of their gene drives could drive a small, caged population of the mosquito Anopheles gambiae to extinction—the first time a gene drive had shown itself capable of doing this. The next step is to try this in a larger caged population.

There are also worries about how gene drives might be used to create a weapon. …The need to find ways to guard against such attacks is one of the reasons that the Pentagon’s Defence Advanced Research Projects Agency (darpa) gives for its work on gene drives. Renee Wegrzyn, programme manager for darpa’s “Safe Genes” project, says the work is to prevent “technological surprise”, whether in the form of an unintended consequence or nefarious use. One of the academic teams she funds has made progress in developing anti-crispr enzyme systems that one day might be able to inhibit a drive’s operation.

Oversight needs not just to bring together a range of government agencies; it requires co-operation between governments, too. The Cartagena Protocol on Biosafety, which entered into force under the un Convention on Biological Diversity (cbd) in 2003, provides controls on the transfer of genetically modified organisms. But how it applies to gene drives is unclear—and besides, America has never ratified the convention. An attempt to ban gene-drive research through the cbd, which was backed by the etc Group and other ngos, failed at the convention’s biennial meeting in Cancún in 2016…Like the reintroduction of vanished species advocated by the rewilding movement, gene-drive technology will provide new arenas for the fight between those who wish to defend nature and those who wish to tame it.

Meddling with Nature: Is it Right? Is it Fair?

Many envisioned environmental applications of newly developed gene-editing techniques such as CRISPR might provide profound benefits for ecosystems and society. But depending on the type and scale of the edit, gene-edited organisms intentionally released into the environment could also deliver off-target mutations, evolutionary resistance, ecological disturbance, and extinctions. Hence, there are ongoing conversations about the responsible application of CRISPR, especially relative to the limitations of current global governance structures to safeguard its use,   Largely missing from these conversations is attention to local communities in decision-making. Most policy discussions are instead occurring at the national or international level even though local communities will be the first to feel the context-dependent impacts of any release. ..

CRISPR gene editing and other related genetic technologies are groundbreaking in their ability to precisely and inexpensively alter the genome of any species. CRISPR-based gene drives hold particular import because they are designed to rapidly spread genetic changes—including detrimental traits such as infertility—through populations of sexually reproducing organisms, to potentially reach every member of a species. Villages in Burkina Faso are weighing the release of gene drive–bearing mosquitoes that could suppress malaria. Nantucket Island residents in the United States are considering the release of genetically engineered white-footed mice to deplete Lyme disease reservoirs. New Zealand communities are discussing the possibility of using genetic methods to eliminate exotic predators.

But what if a gene drive designed to suppress an invasive species escaped its release site and spread to a native population? Or if a coral species gene edited to better adapt to environmental stressors dominated reef ecosystems at the expense of a diversity of naturally evolving coral species and the fish that depend on them ? The gravity of these potential outcomes begs the question: Should humans even be meddling with the DNA of wild organisms? The absence of generally agreed on answers can be used to support calls for moratoria on developing and releasing genetically altered organisms, especially those with gene drives (6).

However, the promising benefits of environmental gene editing cannot be dismissed. Gene drives may provide a long-sought-after tool to control vectors of infectious disease and save millions of human lives. Projects to conserve ecosystems or promote species resilience are often intended to repair human-inflicted environmental damage. Put simply, either using this technology irresponsibly or not using it at all could prove damaging to humans, our welfare, and our planet.

At the international level, the Convention on Biological Diversity (CBD) has enlisted an expert technical panel to, in part, update its Cartagena Protocol (of which the United States is not a party) that oversees transboundary transport of living modified organisms to accommodate gene drive–bearing organisms. The International Union for the Conservation of Nature (IUCN) is also developing policy to address the release of gene-edited organisms. Although the CBD and the IUCN offer fora to engage diverse public feedback, a role largely fulfilled by civil society groups, none of these agencies currently use the broad and open deliberative process we advocate….

Different societal views about the human relationship to nature will therefore shape decision-making. Local community knowledge and perspectives must therefore be engaged to address these context-dependent, value-based considerations.  A special emphasis on local communities is also a matter of justice because the first and most closely affected individuals deserve a strong voice in the decision-making process…Compounding this challenge is that these decisions cannot be made in isolation. Organisms released into local environments may cross regional and even international borders. Hence, respect for and consideration of local knowledge and value systems are necessary, but insufficient, to anticipate the potentially ramifying global implications of environmental release of gene-edited organisms. What is needed is an approach that places great weight on local perspectives within a larger global vision…

The needs of ecosystems could also be given voice to inform deliberative outcomes through custodial human proxies. Inspired by legislative precedent set by New Zealand, in which the Whanganui River was granted legal “personhood,” human representatives, nominated by both an international body like the IUCN and the local community, would be responsible for upholding the health and interests of the ecosystems in question. Proposed gene-editing strategies would be placed in the larger context of alternative approaches to address the public health or environmental issue in question…

An online registry for all projects intending to release genetically engineered organisms into the environment must be created. Currently, no central database exists for environmental gene-editing applications or for decision-making outcomes associated with their deployment, and this potentially puts the global community at risk…A global coordination task force would be charged with coordinating multiple communities, nations, and regions to ensure successful deliberative outcomes. As a hypothetical example, genetic strategies to eliminate invasive possums from New Zealand must include representatives from Australia, the country likely to be affected should animals be transported outside the intended range. Similarly, the African Union is currently deliberating appropriate governance of gene drive–bearing mosquitoes to combat malaria on a regional scale.

Crabs in Radioactive Seas: Kara Sea

The Soviet Union during the 1960s and 70s dumped several hundred containers with solid radioactive waste in the Blagopoluchie Bay in Novaya Zemlya. Back then, these waters were covered with ice overwhelming parts of the year.  Today, that is quickly changing. The bay located in the northern part of the Russian Arctic archipelago is now ice-free increasing parts of the year. With the retreating ice follow new species.

Researchers from the Russian Shirshov Institute of Oceanology have comprehensively studied the eco system of the bay for several years. Among their key findings is a quickly growing number of snow crabs. In this year’s research expedition to the remote waters, the researchers were overwhelmed by the numbers. According to the institute, the crab invasion can be described «as avalanche».

The number of crabs in the area is now estimated to almost 14,000 per hectare, the institute informs. With the help of underwater photo and video footage, the researchers have studied how the crab expansion is leading to a other reduction in other marine life on the sea bottom.    A further spread in the other parts of the Kara Sea is imminent, and the Russian Fisheries Agency (Rosrybolovstvo) believe that the Kara Sea will ultimately become an area with commercial crab fishing.

But Kara seas is a major nuclear waste dump…No major leakage from the radioactive materials have so far been registered.  Soviet authorities are believed to have dumped about 17,000 containers with solid radioactive wastes in Arctic waters and primarily in the Kara Sea. More than 900 containers are located on the bottom of the Blagopoluchie Bay. Also a number of reactor compartments were dumped, as well as three nuclear subs and other nuclear materials.

Future of Green Life Depends on a Toilet

Innovator Cranfield University, U.K.: Putting down the toilet lid activates a dry flush. The motion turns a set of gears that drop feces and urine into a pan, where they are separated and either combusted into ash that can be thrown away or filtered into clean water that could be used to water plants, for instance, though not drinking. It was one of the few completely standalone toilets at the expo, able to function without links to water, sewer or electric lines.

The Innovator: Helbling Group, Switzerland: Helbling’s self-contained toilet system
Similar to other models, this toilet is a mostly self-contained system that transforms waste into clean water and a form of charcoal. But its makers, who were contracted by the Gates Foundation to develop this model, also had modern design in mind: A sleek, black-and-white prototype includes a touchpad for the flush and a container that can be detached to dump out excess water. While it doesn’t have to connect to water or sewer lines, one limit is that the model still needs electricity from an outside source

Sedron Technologies makes the Janicki Omni Processor, a small-scale waste-treatment plant that can filter wet fecal matter so thoroughly that the resulting water is not only free of bacteria and viruses but also safe for drinking. At its highest capacity the plant can manage waste for up to 500,000 people, the same range as two other plants featured at the expo. A trial has been running in Dakar, Senegal, over the past three years to identify and fix technical problems.

The 500 Cases of Marine Pollution

An international law enforcement operation against maritime pollution has revealed hundreds of violations and exposed serious cases of contamination worldwide.  Codenamed 30 Days at Sea, the month-long (1-31 October) operation saw some 276 law enforcement and environmental agencies across 58 countries detect more than 500 offences, including illegal discharges of oil and garbage from vessels, shipbreaking, breaches of ship emissions regulations, and pollution on rivers and land-based runoff to the sea.  More than 5200 inspections have resulted in at least 185 investigations, with arrests and prosecutions anticipated.

“Criminals believe marine pollution is a low-risk crime with no real victims.  This is a mistake and one which INTERPOL and our partners are addressing as demonstrated by this operation,” said INTERPOL Secretary General Jürgen Stock.  Cases of serious contamination included the dumping of animal farm waste in Philippine coastal waters where local communities collect shellfish and children play.  In Germany, a vessel discharged 600 litres of palm oil into the sea. Ghana uncovered gallons of waste oil in large bottles thought to be illegally dumped at sea.  Authorities prevented an environmental disaster in Albania by securing waters around a sinking vessel containing some 500 litres of oil. Similarly, the pollution threat resulting from the collision of two ships in French waters was contained thanks to preventive action during the operation.

Innovative technologies permitted authorities to detect offences, including the use of satellite images (in Argentina and Sweden), aerial surveillance (Canada and Italy), drones (Nigeria, Indonesia and Pakistan) and night vision cameras.

Ozone Layer Recovery Success

The study, “Scientific Assessment of Ozone Depletion: 2018”, is the latest in a series of reports, released every four years, which monitor the recovery of ozone in the stratosphere, a layer that protects life on Earth from harmful layers of ultraviolet rays from the sun.  It shows that the concentration of ozone-depleting substances continues to decrease, leading to an improvement in the layer since the previous assessment carried out in 2014.

Ozone in parts of the stratosphere has recovered at a rate of 1-3 percent since 2000 and, at projected rates, Northern Hemisphere and mid-latitude ozone is scheduled to heal completely by the 2030s, followed by the Southern Hemisphere in the 2050s and polar regions by 2060.

This is due to internationally agreed actions carried out under the historic Montreal Protocol, which came into being over 30 years ago in response to the revelation that chlorofluorocarbons (CFCs) and other ozone-depleting substances – used in aerosols, cooling and refrigeration systems, and many other items – were tearing a hole in the ozone layer and allowing dangerous ultraviolet radiation to flood through.

Next year, the Protocol is set to be strengthened with the ratification of the Kigali Amendment, which calls for the future use of powerful climate-warming gases in refrigerators, air conditioners and related products to be slashed…The writers of the report found that, if the Kigali Amendment is fully implemented, the world can avoid up to 0.4 percent of global warming this century, meaning that it will play a major role in keeping the global temperature rise below 2°C.

Peruvian Amazon: Oil Pollution & Human Rights

On September 15, 2018 indigenous federations from the Amazonian Loreto region of northern Peru scored a small victory in the fight for community rights. Representatives from four federations signed an agreement with the Peruvian government and the state-owned enterprise PetroPerú that acknowledges prior consultation as part of the new contracting process for petroleum Block 192. Under the new agreement, Block 192 will undergo a community consultation process before PetroPerú awards a new contract for operating the oil field…

Under the formal resolution with Prime Minister César Villanueva, the Ministry of Energy and Mining, and PetroPerú, the government will complete the community consultation for Block 192 between December 2018 and March 2019.

Extending across the Tigre, Corrientes, Pastaza and Marañón river basins in Peru’s remote Loreto province, Block 192 is the largest-yielding oil field in Peru, accounting for 17 percent of the country’s production. The government plans to continue production of oil at the block for another 30 years, adding to the almost 50 years of oil activity in the region. The oil field is currently operated by Canadian-based Frontera Energy, whose contract with PetroPerú is set to expire in September 2019.

American-based Occidental Petroleum discovered oil in the region in 1972 and a succession of companies, including the Dutch-Argentinian conglomerate Pluspetrol, left Block 192 (previously Block 1-AB) heavily polluted. While Peru’s Agency for Environmental Assessment and Enforcement fined Pluspetrol for violations, the Peruvian government remains in a protracted legal fight with the oil giant. A majority of the fines are outstanding and Pluspetrol denies any wrongdoing, despite settling with a local community in 2015.

For over 40 years, the indigenous Kichwa, Quechua, Achuar, and Urarina peoples who live near the oil field have been exposed to salts, heavy metals and hydrocarbons. According to a 2018 toxicology study by Peru’s National Center for Occupational Health and Environmental Protection for Health, over half of the indigenous residents in the region’s four basins have blood lead levels that surpass international recommended limits. A third have levels of arsenic and mercury above the levels recommended by Peru’s Ministry of Health…

The actual cost of cleaning up Block 192, along with neighboring Block 8, would approach $1 billion. To make matters more challenging, the $15 million fund of Peruvian government is almost exhausted..”

What to Do with Radioactive Pools

More than 60,000 tons of highly radioactive spent nuclear fuel is stored on the shores of four of the five Great Lakes at the Border between United States and Canada — in some cases, mere yards from the waterline — in still-growing stockpiles…It remains on the shorelines because there’s still nowhere else to put it…

The nuclear power industry and its federal regulator, the U.S. Nuclear Regulatory Commission, point to spent nuclear fuel’s safe on-site storage over decades. But the remote possibility of a worst-case scenario release — from a natural disaster, a major accident, or an act of terrorism — could cause unthinkable consequences for the Great Lakes region.   Scientific research has shown a radioactive cloud from a spent fuel pool fire would span hundreds of miles, and force the evacuation of millions of residents in Detroit, Chicago, Cleveland, Toronto or other population centers, depending on where the accident occurred and wind patterns.

For five years, Michigan residents, lawmakers, environmental groups and others around the Midwest have, loudly and nearly unanimously, opposed a planned Canadian underground repository for low-to-medium radioactive waste at Kincardine, Ontario, near the shores of Lake Huron. Meanwhile, spent nuclear fuel, vastly more radioactive, sits not far from the shores of  four Great Lakes — Michigan, Huron, Erie and Ontario — at 15 currently operating or former nuclear power plant sites on the U.S. side. In Michigan, that includes Fermi 2; the Donald C. Cook nuclear plant in Berrien County; the Palisades nuclear plant in Van Buren County, and the former Big Rock Point nuclear plant in Charlevoix County, which ceased operation in 1997 and where now only casks of spent nuclear fuel remain.

Neither the U.S. nor the Canadian government has constructed a central collection site for the spent nuclear fuel. It’s not just a problem in the Great Lakes region — more than 88,000 tons of spent nuclear fuel, an amount that is rising, is stored at 121 U.S. locations across 39 states.

Spent nuclear fuel isn’t only radioactive, it continues to generate heat. It requires storage in pools with circulating water for typically five years before it can be moved into so-called dry-cask storage — concrete-and-steel obelisks where spent fuel rods receive continued cooling by circulating air.In practice, however, because of the high costs associated with transferring waste from wet pools to dry casks, nuclear plants have kept decades worth of spent fuel in wet storage. Plant officials instead “re-rack” the pools, reconfiguring them to add more and more spent fuel, well beyond the capacities for which the pools were originally designed.

Only in recent years have nuclear plants stepped up the transition to dry cask storage because there’s no room left in the wet pools. Still, about two-thirds of on-site spent nuclear fuel remains in wet pools in the U.S….That’s a safety concern, critics contend. A catastrophe or act of terrorism that drains a spent fuel pool could cause rising temperatures that could eventually cause zirconium cladding — special brackets that hold the spent fuel rods in bundles — to catch fire.  Such a disaster could be worse than a meltdown in a nuclear reactor, as spent nuclear fuel is typically stored with nowhere near the fortified containment of a reactor core.

At Fukushima…what almost happened — at the plant’s Unit 4 spent-fuel pool that gives nuclear watchdogs nightmares.  A hydrogen explosion four days into the disaster left the building housing the Unit 4 spent-fuel pool in ruins. The pool was seven stories up in a crumbling, inaccessible building.  It “was so radioactive, you couldn’t put people up there,” von Hippel said. “For about a month after Fukushima, people didn’t know how much water was in the pool. They were shooting water up there haphazardly with a hose, trying to drop it by helicopter.”  Two weeks after the earthquake and tsunami, the Japanese Atomic Energy Commission secretly conducted a worst-case scenario study of the ongoing disaster. The biggest fear that emerged: that a self-sustaining fire would start in the Unit 4 spent fuel pool, spreading to the nearby, damaged reactors. That, they found, would release radiation requiring evacuations as far away as 150 miles, to the outskirts of Tokyo and its more than 13.4 million residents. “That was the devil’s scenario that was on my mind,” Chief Cabinet Secretary Yukio Edano said during a special commission’s 2014 investigation of the accident.“Common sense dictated that, if that came to pass, then it was the end of Tokyo.”   What kept the spent fuel rods covered with water in Unit 4 was a miraculous twist of fate: The explosion had jarred open a gate that typically separated the Unit 4 spent fuel pool from an adjacent reactor pool.  “Leakage through the gate seals was essential for keeping the fuel in the Unit 4 pool covered with water,” a 2016 report on the Fukushima accident by the U.S. National Academies of Sciences, Engineering and Medicine concluded. “Had there been no water in the reactor well, there could well have been severe damage to the stored fuel and substantial releases of radioactive material to the environment.”

The U.S. nuclear industry sees Fukushima differently — in some ways as a success story.  “At Fukushima, you not only had a tsunami, you blew up the buildings … and you still did not drain the pool,” said Rod McCullum, senior director for fuel and decommissioning at the Nuclear Energy Institute, the trade association for nuclear utilities in the U.S.  “Those pools and those casks withstood explosions and earthquakes and tsunamis, all on the same day.”  A scenario where a fire can occur by the draining of water from a spent-fuel pool “has never been demonstrated,” McCullum said. He noted safety measures added in the U.S. since Fukushima include the ability to provide extra pumps and water supplies, in minutes or hours, should a spent fuel pool become breached and lose water — even if the disaster required that the resources be brought in by air from farther away….

Because nuclear power is much more widely used in Canada — the province of Ontario alone has 20 nuclear reactors at three plants — it also generates much more nuclear waste.  In Ontario, nearly 52,000 tons of spent nuclear fuel is stored on-site at nuclear plants along Lakes Huron and Ontario.“There’s a huge amount of high-level, radioactive waste stored right along the water,” said Edwards, the president of the nonprofit Canadian Coalition for Nuclear Responsibility  Like the U.S., Canada is seeking a long-term storage solution that will involve a central underground repository. Unlike the U.S., the Canadian government is seeking willing hosts, promising jobs and economic activity. …Even if a central repository is one day approved, another complication arises — how to get two generations of the most dangerous industrial waste man has ever created from sites all over the country to one point….

Germany, in the 1980s, tried using an abandoned salt and potash mine to store barrels of nuclear waste over 30 years, the Asse II mine.  It’s now prompting a cleanup that may take 30 years and cost nearly $12 billion U.S. dollars. The government has disputed the contention of workers at the mine that they were exposed to excessive levels of radiation, causing an unusual number of cancers….Nuclear power is projected to drop as a percentage of the world’s power generation mix from 10 percent in 2017 to just 5.6 percent by 2050, a report issued by the International Atomic Energy Agency this summer found…

If central repository solutions aren’t found, within years, the re-licensing of some early dry-cask storage facilities will come into play, as they meet a lifespan they were never expected to reach. “The age of nuclear power is winding down, but the age of nuclear waste is just beginning,” Edwards said.

Dismantling Nuclear Reactors at Fukushima

In the aftermath of the Fukushima nuclear disaster in 2011, Naraha decided to oppose nuclear energy and call for the closure of the Fukushima No. 2 nuclear power plant that it co-hosts on the coast of the prefecture.  Since the 1970s, the town has been home to the No. 2 plant, which first went into service in 1982.  For decades, Naraha has received central government grants and subsidies for hosting the No. 2 plant, as well as tax revenues from TEPCO and its affiliates operating in the town.The plant also employed 860 people, many of them from Naraha and its surrounding communities.

Naraha had a population of about 8,000 before the Great East Japan Earthquake and tsunami caused the triple meltdown at TEPCO’s Fukushima No. 1 nuclear plant in March 2011. The crippled plant is located within 20 kilometers from Nahara.  The quake and tsunami also created a scare at the No. 2 plant by leaving the facility with only a limited power supply from external sources and emergency diesel generators to cool the reactors. But the plant brought the situation under control.

After long remaining silent about the fate of the No. 2 plant, TEPCO decided to retire all of its four reactors, which were approaching their legal operating limit of 40 years. If the power company wanted to continue operations at the plant, it would have to spend hundreds of billions of yen on upgrades to meet the more stringent safety standards that were set after the accident at the No. 1 plant…

Although Naraha and Tomioka officials share concerns about their municipalities’ financial futures, they see a silver lining in the situation at the Fukushima No. 1 nuclear plant.  Both towns have served as front-line bases for workers involved in decommissioning of the stricken plant.  About 5,000 workers a day who are involved in the decommissioning effort provide steady business for convenience stores and other shops in the two towns. Business hotels, dorms and apartment buildings have been built in the towns and neighboring communities to accommodate the workers. Work to dismantle the No. 1 plant is expected to take decades to complete. Local officials said the closure of the No. 2 plant could bring about a similar economic boon. “Decommissioning can become a major industry,” Naraha Mayor Matsumoto said.

Underwater Nuclear Wrecks

Russian scientists have said that radioactive waste sunk in the Arctic by the Soviet Navy has not leaked any contamination….  Data on the scuttled cargoes –– which includes several thousand containers of radioactive waste, as well as an entire nuclear submarine –– come from a month-and-a-half-long expedition in the Kara Sea conducted by the Russian Academy of Sciences Institute of Oceanology.  Mikhail Flint, the institute’s head, told reporters last week that scientists on the expedition had managed to significantly improve their maps of where the sunken waste lies, especially in the area of the Novaya Zemlya archipelago, a former Soviet nuclear bomb testing site.  From Novaya Zemlya’s craggy coast, the expedition conducted additional research mapping radioactive hazards in the White Sea, and then progressed to the Laptev Sea some 2000 nautical miles to the east.

Since the first decades of the 2000s, these mapping and measuring expeditions have taken place on an annual basis. Environmentalists fear the waste could eventually rupture and spoil thousands of square kilometers of fertile Arctic fishing grounds.

Beginning in 1955 and continuing until the early 1990s, the Russian Navy dumped enormous amounts of irradiated debris — and it one case an entire nuclear submarine — into the waters of the Arctic. It was not, however, until 2011 that the Russian government admitted this on an international level.  That year, Moscow shared with Norwegian nuclear officials the full scope of the problem. The list of sunken objects was far more than had initially been thought, and included 17,000 containers of radioactive waste; 19 ships containing radioactive waste; 14 nuclear reactors, including five that still contain spent nuclear fuel; the K-27 nuclear submarine with its two reactors loaded with nuclear fuel, and 735 other pieces of radioactively contaminated heavy machinery.

How Rivers Die

Kapuas, Indonesia’s longest river support somes 3m people…One reason that the water is so murky is deforestation. Since the 1970s logging has enriched locals while stripping away the vegetation that held the soil in place. The Centre for International Forestry Research (CIFOR) found that between 1973 and 2010 over 100,000 square kilometres of forest was lost on Kalimantan, or a third of the original coverage. A national moratorium that began in 2011 has done little to still the axes. As a result, torrential tropical rains wash lots of loose earth into the Kapuas.

Illegal gold-mining compounds the problem. Locals tear up the riverbed with diggers or blast the banks with high-pressure hoses, then sieve the mud for gold. Mercury, which the miners use to separate gold from sediment, but which is poisonous to humans and fish alike, leaks into the river.

The riverbank is punctuated with corrugated-iron towers, which emit birdsong from loudspeakers. These are designed to lure swiftlets, who make their nests with saliva. The nests of swiftlets  are considered a delicacy and aphrodisiac by many Chinese.* Deane, a shop owner, built his tower last December after seeing others do the same. He sells the nests to a wholesaler for about 15m rupiah ($1,025) a kilogram…

In Kapuas Hulu, an upstream district, half the population rely on the river for drinking water. A quarter have no toilet. Even where bathrooms do exist along the river, they are often floating cubicles with a hole in the floorboards. Cows and goats, living in wooden riverside cages, also defecate straight into the Kapuas

The Kapuas passes through seven districts. Midstream ones, such as Sintang and Sanggau, earn hefty tax revenues by encouraging palm-oil plantations. But downstream districts suffer from the resulting silt, traffic and run-off without receiving any of the benefits. The same problem occurs at a village level. Mr Hadi says that fishing by sprinkling poisonous leaves on the water (the stricken fish float to the surface) is forbidden but other village heads do not enforce the rules…

A study by CIFOR on the income of villagers living near the Kapuas river found that the best-paid palm-plantation workers earned 50% more than the most successful fishermen. (Gold miners made three times as much—and spent more on education.)…But the environmental damage is plain to see. The river here is brown, clouded by silt. A study published in 2016 found that levels of phosphates in the water, from fertilisers and villagers washing themselves with soap, are highest near urban areas and palm plantations.

Down in Pontianak, the river water is darker still, occasionally brightened by oil slicks. Water bottles and instant-noodle packets cling together to form plastic islands.

Excerpts from  Indonesia’s Longest River,  Economist, Aug. 25, 2018

*According to Wikipedia: Authentic bird’s-nest soup is made from nests of some species of swiftlet.  Instead of twigs, feathers and straw, these swiftlets make their nest only from strands of their gummy saliva, which hardens when exposed to air. Once the nests are harvested, they are cleaned and sold to restaurants. Eating swiftlet nest material is believed to help maintain skin tone, balance qi (“life energy”) and reinforce the immune system… (Dictionary of Traditional Chinese Medicine, The History of Chinese Medicine and the Nutrition Table).

A Gasfield and the Cows Next to it

High levels of a radioactive material and other contaminants have been found in water from a West Australian fracking site* but operators say it could be diluted and fed to beef cattle.  The revelations illustrate the potential risks associated with the contentious gas extraction process known as fracking, or hydraulic fracturing, as the Turnbull government pressures states to ease restrictions on the industry and develop their gas reserves.

The findings were contained in a report by oil and gas company Buru Energy that has not been made public. It shows the company also plans to reinject wastewater underground – a practice that has brought on seismic events when used in the United States.

Buru Energy has been exploring the potentially vast “tight gas” resources of the Kimberly region’s Canning Basin. The work was suspended when the WA government last year introduced a fracking moratorium, subject to the findings of a scientific inquiry.

In a submission to the inquiry obtained by the Lock the Gate Alliance, Buru Energy said a “relatively high concentration” of Radium-228…The samples exceeded drinking water guidelines for radionuclides. However Buru Energy said samples collected from retention ponds were below guideline levels and the water posed “no risk to humans or animals”.  Water monitoring also detected elevated levels of the chemical elements barium, boron and chloride….Buru Energy said while the water was not suitable for human consumption, the “reuse of flowback water for beef cattle may also be considered”.  The water did not meet stockwater guidelines but this could be addressed “through dilution with bore water”.

The company’s development in the Yulleroo area of the basin could lead to 80 wells operating over 20 years….The company insists its fracking fluids are non-toxic and to illustrate its safety, executive chairman Eric Streitberg drank the fluid at the company’s 2016 annual general meeting.

Excerpt from  Nicole Hasham Radioactive water reignites concerns over fracking for gas, Sydney Morning Herald, June 24, 2018

*Fracking, which involves injecting water mixed with chemicals and sand deep underground in order to fracture rock and release oil and gas, generates large amounts of wastewater. … In some cases, improper handling of this waste water has resulted in the release of radioactive fracking waste that has contaminated streams and rivers, Science Magazine, Apr 9, 2015

Lead and Mercury in the Seas

The levels of lead and mercury in the sea reduce noticeably following concrete actions to limit their release, recent research at the IAEA using nuclear techniques has shown. The banning of leaded petrol and the closure of a mercury discharging plant have led to decreases in pollution levels over 10-15 years.

This is the case for lead, which when consumed by fish which is in turn eaten by people, can cause damage to the human nervous system and internal organs. Many different activities such as mining or smelting in metallurgy and the burning of coal as well as lead’s use in batteries, paint, ceramics and other everyday items can release it into the environment. The biggest source of lead pollution in the last century was related to the use of leaded petrol.

As part of efforts to develop new methods to determine the source and levels of lead pollution, researchers at the IAEA Environment Laboratories analysed sediments from the Baltic Sea and the Caribbean Sea. In mapping the pollution history in a sediment core from the Baltic coast of Germany, researchers could clearly observe that within 10 to 15 years of phasing out lead in petrol by 1996, lead pollution levels in the sea had decreased..

In addition, IAEA researchers have successfully developed methods to use lead isotope ratios to determine the source of lead pollution and assess whether it is naturally present or the result of anthropogenic activities, since natural and anthropogenic lead sources will show different isotopic fingerprints and isotope compositions….

IAEA scientists’ analysis of a dated sediment core in a Caribbean bay shows total mercury (Hg) levels rapidly decreased after the closure of a discharging plant…Mercury was used in an alkali plant there as a catalyser, and in the 1970s, high concentrations were found in water, sediments and marine organisms as a result of discharges from the plant.  Years later, after the plant had been closed, IAEA researchers showed, by analysing sediment core taken from the bay, that levels of total mercury had started to decrease.  While remnants of this pollution are still buried in the sediment, acute toxicity has been greatly reduced.

An Unforgettable Type of Pollution

May 2018: The environmental damage around the site of two Royal Dutch Shell oil spills in Nigeria a decade ago has worsened significantly after years of delay to cleanup efforts, according to a report that the oil giant has been accused of trying to shield from public view.  The spills from a ruptured Shell pipeline spewed thousands of barrels of oil over parts of the Bodo fishing community in the crude-rich Niger Delta. Although the company in 2015 reached an out-of-court settlement with the local community, admitting to liability and agreeing to pay £55 million, or around $80 million at the time, in compensation, controversy around the case has remained.

A United Nations body, in a 2011 report, found extensive environmental damage around Bodo. Four years later, an assessment to prepare the cleanup found soil contamination had worsened while cleanup efforts languished and illegal refining and oil theft added to pollution in the area, according to an academic paper published last month. That has left the community facing potentially toxic pollution and “catastrophic” damage to the environment, the paper said.  The 2015 analysis was commissioned by the Bodo Mediation Initiative, a consortium established to oversee the cleanup in the area. Shell is a member of the group along with local stakeholders.

At least one of the authors urged the findings to be widely distributed because they pointed to significant health risks to the local community. Kay Holtzmann, the cleanup project’s former director, said in a letter reviewed by the Journal that Shell had denied him permission to publish the study’s results in a scientific journal.

But the academic paper* said the site survey contained new facts. The average surface soil contamination in Bodo had tripled since the original U.N. probe,the paper said. Out of 32 samples taken from the top two inches of soil in the area around Bodo, only one was within Nigeria’s legally acceptable limit for oil contamination, the paper added.

The Unquenchable Thirst: water mismanagement

Most of the drinking water consumed in Beijing has travelled 1,432km (895 miles), roughly the distance from New York to Orlando, Florida. Its journey begins in a remote and hilly part of central China at the Danjiangkou reservoir, on the bottom of which lies the drowned city of Junzhou. The water gushes north by canal and pipeline, crosses the Yellow river by burrowing under it, and arrives, 15 days later, in the water-treatment plants of Beijing. Two-thirds of the city’s tap water and a third of its total supply now comes from Danjiangkou.

This winter and spring, the reservoir was the capital’s lifeline. No rain or snow fell in Beijing between October 23rd 2017 and March 17th 2018—by far the longest drought on record. Yet the city suffered no supply disruptions, unlike Shanxi province to the west, where local governments rationed water. The central government is exultant, since the project which irrigates Beijing was built at vast cost and against some opposition.

The South-to-North Water Diversion Project—to give the structure its proper name—is the most expensive infrastructure enterprise in the world. It is the largest transfer of water between river basins in history, and China’s main response to its worst environmental threat, which is (despite all the pollution) lack of water.

The route between Beijing and Danjiangkou, which lies on a tributary of the Yangzi, opened in 2014. An eastern route opened in 2013 using the ancient Grand Canal between Hangzhou and the capital. (Jaw-dropping hydrological achievements are a feature of Chinese history.) A third link is planned on the Tibetan plateau, but since that area is prone to earthquakes and landslides, it has been postponed indefinitely…

Downstream from Danjiangkou, pollution has proved intractable. By diverting water from the Yangzi, the project has made the river more sluggish. It has become less able to wash away contaminants and unable to sustain wetlands, which act as sponges and reduce flooding. To compensate for water taken from their rivers, local governments are also building dams wherever they can to divert it back again. Shaanxi province, for example, is damming the Han river to transfer water to its depleted river Wei….Worst of all, the project diverts not only water but money and attention from China’s real water problem: waste and pollution.

A Slow-Burning Tragedy

Charcoal is one of the biggest informal businesses in Africa. It is the fuel of choice for the continent’s fast-growing urban poor, who, in the absence of electricity or gas, use it to cook and heat water. According to the UN, Africa accounted for three-fifths of the world’s production in 2012—and this is the only region where the business is growing. It is, however, a slow-burning environmental disaster.

In Nyakweri forest, Kenya, the trees are ancient and rare. Samwel Naikada, a local activist, points at a blackened stump in a clearing cut by burners. It is perhaps 400 years old, he says. The effect of burning trees spreads far. During the dry season, the forest is a refuge for amorous elephants who come in from the plains nearby to breed. The trees store water, which is useful in such a parched region. It not only keeps the Mara river flowing—a draw for the tourists who provide most of the county government’s revenue. It also allows the Masai people to graze their cows and grow crops. “You cannot separate the Masai Mara and this forest,” says Mr Naikada….

Nyakweri is hardly the only forest at risk. The Mau forest, Kenya’s largest, which lies farther north in the Rift Valley, has also been hit by illegal logging. Protests against charcoal traders (!) broke out earlier this year, after rivers that usually flow throughout the dry season started to run dry. In late February a trader’s car was reportedly burned in Mwingi, in central Kenya, by a group of youngsters who demanded to see the trader’s permits. At the end of February 2018 the government announced an emergency 90-day ban on all logging, driving up retail prices of charcoal by 500%, to as much as 5,000 shillings a bag in some cities.

The problems caused by the charcoal trade have spread beyond Kenya. In southern Somalia, al-Shabab, a jihadist group, funds itself partly through the taxes it levies on the sale of charcoal (sometimes with the help of Kenyan soldiers, who take bribes for allowing the shipments out of a Somali port that Kenya controls). The logging also adds to desertification, which, in turn, causes conflict across the Sahel, an arid belt below the Sahara. It forces nomadic herders to range farther south with their animals, where they often clash with farmers over the most fertile land.

In the power vacuum of the eastern Democratic Republic of Congo, rampant charcoal logging has destroyed huge swathes of Virunga National Park. That threatens the rare gorillas which tourists currently pay as much as $400 a day to view, even as it fuels the conflict.

In theory, charcoal burning need not be so destructive. In Kenya the burners are meant to get a licence. To do so, they have to show they are replacing the trees they are cutting down and that they are using modern kilns that convert the trees efficiently into fuel. But, admits Clement Ngoriareng, an official at the Kenya Forest Service (KFS), the rules are laxly enforced. Some suspect that powerful politicians stymie efforts to police burners.

A Nuclear Titanic? the First Floating Nuclear Plant

A massive floating nuclear power plant is now making its way toward its final destination at an Arctic port (April 30, 2018)… It’s the first nuclear power plant of its kind, Russian officials say.  Called the Akademik Lomonosov, the floating power plant is being towed at a creeping pace out of St. Petersburg, where it was built over the last nine years. It will eventually be brought northward, to Murmansk – where its two nuclear reactors will be loaded with nuclear fuel and started up in the fall of 2018.

From there, the power plant will be pulled to a mooring berth in the Arctic port of Pevek, in far northeast Russia. There, it will be wired into the infrastructure so it can replace an existing nuclear power installment on land.  Critics of the plan include Greenpeace, which recently warned of a “Chernobyl on ice if Russia’s plans to create a fleet of floating nuclear power stations result in a catastrophe.

Russian officials say the mandate of the Akademik Lomonoso is to supply energy to remote industrial plants and port cities, and to offshore gas and oil platforms.  “The nuclear power plant has two KLT-40S reactor units that can generate up to 70 MW of electric energy and 50 Gcal/hr of heat energy during its normal operation,” Rosatom said. “This is enough to keep the activity of the town populated with 100,000 people.”

It will take more than a year for the power plant to reach its new home port. The original plan had called for fueling the floating plant before it began that journey, at the shipyard in central St. Petersburg – but that was scuttled in the summer of 2017, after concerns were raised both in Russia and in countries along the power plant’s route through the Baltic Sea and north to the Arctic. Rosatom says it hopes the floating nuclear power plant will be online in 2019.

Breathing in Plutonium Dust: Hanford

The Energy Department project to tear down the Plutonium Finish Plant at the Hanford Site was halted in mid-December 2017 after radioactive dust was discovered far off the plant site. T As crews demolished a shuttered nuclear weapons plant during 2017 in central Washington, specks of plutonium were swept up in high gusts and blown miles across a desert plateau above the Columbia River.  The releases at the Department of Energy cleanup site spewed unknown amounts of plutonium dust into the environment, coated private automobiles with the toxic heavy metal and dispensed lifetime internal radioactive doses to 42 work

The contamination events went on for nearly 12 months, getting progressively worse before the project was halted in mid-December. Now, state health and environmental regulators, Energy Department officials and federal safety investigators are trying to figure out what went wrong and who is responsible.

The events at the Hanford Site, near the Tri-Cities area of Richland, Pasco and Kennewick, vividly demonstrate the consequences when a radioactive cleanup project spirals out of control.

The mishap occurred at one of the nation’s most radioactively contaminated buildings, known as the Plutonium Finishing Plant. The factory, which opened in 1949 a few miles from the Columbia River, supplied plutonium for thousands of U.S. nuclear weapons before it was shut down in 1989.
The exposures from the plutonium releases in 2017 were minuscule bestimated to be a small fraction of the background radiation that every human gets from nature. But unlike cosmic radiation or radon gas, plutonium can lodge itself inside the body and deliver tissue damaging alpha particles over a lifetime…. As workers removed equipment to prepare for walls to be torn down, air monitoring alarms sounded almost every day, he said. Workers were subjected to repeated nasal smears to determine if they had breathed plutonium dust, he said….Seven employee automobiles were contaminated at the plant site, according to a Jan. 9, 2018 letter from the state Department of Ecology to Doug Shoop, the federal site chief at Hanford… The demolition, costing $57 million, was being conducted by one of the nation’s largest engineering firms, CH2M, a unit of Texas-based Jacobs Engineering. CH2M is now under federal investigation for the releases, according to a letter sent by the Energy Department’s enforcement office in late March 2018…

In March 2018, the company released a preliminary analysis [pdf] of the contamination and blamed it on a half dozen factors, including a “fixative” that was supposed to bind the dust but was too diluted to work properly and a decision to accelerate demolition when the contamination seemed to be stable.  The Energy Department plan for the demolition originally required the contractor to remove debris as it accumulated. But in January 2017, just before the first releases, officials authorized CH2M to allow the debris to pile up, according to a monthly site report by an inspector for the Defense Nuclear Facilities Safety Board, an independent agency.  In fact, workers at the plant said the demolition site was ringed by 8-foot-tall piles of radioactive debris with little to prevent dust from blowing off

The problems at the Plutonium Finishing Plant were not an isolated event at Hanford, which has struggled with its cleanup for more than a decade.
Work was stopped five years ago on key parts of a $16.8-billion waste treatment plant that is supposed to turn 56 million gallons of radioactive sludge into glass. Technical deficiencies in its design are still being studied, while delays mount. Several years ago, the Energy Department pushed back the full startup by 17 years to 2039, though it hopes to begin treating some less radioactive waste by 2022….In 2017, a tunnel that stored railroad cars full of contaminated equipment collapsed. The Energy Department pumped the 358-foot long tunnel full of a concrete mixture. A decision is pending about what to do with a second storage tunnel 1,688 feet long.

The state attorney general, along with Hanford Challenge and a union, is suing the Energy Department for venting noxious gases from underground waste tanks over recent years, sickening workers.

Smith, the Ecology manager, said a lot of cleanup progress has been made at Hanford. Hundreds of buildings have been torn down. Much of the soil along the banks of the Columbia River has been cleaned up enough for any future use. And the site’s nine nuclear reactors have been put in stable condition…

One of those facilities, known as 324 Building,[Chemical Materials Engineering Laboratory] was used to extract plutonium from spent fuel, said Robert Alvarez, a former assistant secretary of Energy and a longtime critic of the cleanup. The facility has civilian waste from Germany, sent as part of a research project, as well as large amounts of radioactive waste that was placed in unlined burial pits, he said. Records of what lies in the pits were destroyed in 1988, he said.

Well blowouts and Pipeline breakdowns: Who Profits?

The global oil spill management market size is projected to grow beyond USD 125.62 billion by 2024. Growing incidents of oil spilling in the past along with severe safety and environmental policies are likely to propel the market over the forecast phase (2016-2024). Also, escalating pipeline and seaborne shipping of crude oil and chemicals could positively impact the market further.  The market is fragmented by technologies, techniques, applications, and regions. Technologies are Pre-oil spill and Post-oil spill. Pre-oil spill segment is divided into double-hull, pipeline, leak detection, blow-out preventers, and others. Double-hulling was the dominant segment in 2015 with highest shares.

Marine trade registers for a majority of petroleum products and natural gas transportation. Mounting demand for crude and petroleum products oil in Europe and Asia Pacific will boost the maritime trade growth further. Post-oil spill segments are mechanical, chemical, biological, and physical. Chemical and mechanical containment and recovery are the techniques used in the industry….In 2015, onshore post-oil spill sector was valued close to 60% of the total market demand. Regions such as Norway, U.S, Mexico, Canada, U.S., China, and Nigeria have observed well blowouts and occurrences of pipeline breakdowns. This could be accredited to huge market diffusion in past

Main regions in the market encompass North America, Europe, Asia Pacific, the Middle East and Africa (MEA), and Central & South America. North America was the leading market for pre-oil spill management. It was estimated at 40.1% of total demand in 2015. This region will potentially face lucrative demand due to production activities and increasing oil & gas discovery. Pre-oil spill management shares in Asia Pacific will gain over USD 21,540 million by 2024…  Top companies in the global oil spill management market include OMI Environmental Solutions, Skim Oil Inc., American Green Ventures Inc., and Spill Response Services.

Islands of Paradise, Sewage and Garbage

Cesspools—holes in the ground where untreated human waste is deposited—have become a crisis in Hawaii, threatening the state’s drinking water, its coral reefs and the famous beaches that are the lifeblood of its tourist economy.  Sewage from cesspools is seeping into some of Hawaii’s ocean waters, where it has been blamed for infections suffered by surfers and snorkelers. It is also entering the drinking water in part of the state, pushing nitrate levels close to the legal limit.

Hawaii has 88,000 cesspools across its eight major islands, more than any other state. Collectively, they deposit 53 million gallons of raw sewage into the ground every day, according to the state health department. More than 90% of the state’s drinking water comes from groundwater wells…

Replacing all of the state’s cesspools with alternate sewage systems would cost at least $1.75 billion, according to the health department…At one groundwater well, nitrate levels are already at 8.7 milligrams a liter; the legal limit is 10, and the Department of Health estimated that some parts of the aquifer are already over that limit. Environmentalists say they are worried about the potential effect of the water on infants, who can be killed by high levels on nitrates, which are chemicals found in fertilizer and sewage.

Many bathrooms in homes outside Honolulu still pump sewage into nearby holes in the ground.  Yet, some residents resist plans to replace cesspools, worried about expense. In January 2018, Upcountry Maui residents overwhelmed a Department of Public Health meeting, complaining about potential costs.

The Maritime Environment Protection Authority’s (MEPA) of Sri Lanka spent millions of rupees on coastal cleanups last year — a reflection of “spending public money for public waste,” as the MEPA’s General Manager and CEO, Dr. Terney Pradeep Kumara, puts it.

A large proportion of the problem is attributable to inland waste, he notes. “It is not merely what is dumped directly on the beaches, but all that flows through canals and rivers,” he says, pointing out that other triggers, including the fisheries and the tourism sector, are only secondary to inland waste which ends up on the coast. Added to the burden is the garbage which flows from India, Indonesia and Thailand, he says. The MEPA’s role in controlling pollution covers Sri Lanka’s 1640 km coastal belt and extends up to 200 nautical miles to the deep sea, the area, which, according to Dr. Pradeep Kumara, is eight times the size of Sri Lanka’s land area.

The garbage dumped in the coastal vegetation is contributing to the dengue problem…especially the fishing craft, both in use and abandoned, in which water is stagnated.”   Mitigating inland pollution is seen by MEPA authorities as the first step in realising cleaner beaches. They moot a site-specific garbage disposal system, as opposed to a ‘blanket system’. “What works for Colombo will not work for other areas,” says Dr. Pradeep Kumara.

How to Relocate an Open Wound: Rubbish Dumps

One of the biggest rubbish dumps in South America was closed in January 2018 in Brazil after almost 60 years.The Estructural dump in the country’s capital, Brasilia, had processed more than 1,000 tonnes of rubbish every day. But its closure is likely to have an impact on a nearby favela as many of the residents rely on scavenging.  The regional governor, Rodrigo Rollemberg, says the rubbish scavengers will be paid to work in a recycling centre in cleaner conditions.

“We cannot live with this open wound in the midst of our nation’s capital, a dump where human beings put their lives at risk seeking a livelihood in an undignified way,” he said at the opening of the new landfill which is further out from the city centre.  “Rollemberg hasn’t offered us a real alternative. We cannot survive on that pay,” Valdir Dutra, who has scavenged for 16 years, told Reuters news agency.
