Call for global treaty to end production of ‘virgin’ plastic by 2040

A binding global treaty is needed to phase out the production of “virgin” or new plastic by 2040, scientists have said. The solution to the blight of plastic pollution in the oceans and on land would be a worldwide agreement on limits and controls, they say in a special report in the journal Science. Since …

Researchers are now using hurricane-tracking satellites to combat ocean microplastics

Have you ever wondered how scientists even begin to study things like patterns in ocean pollution and movements of microplastics? Better yet, you can probably imagine the people working the hardest to fight these problems could benefit from useful information like being able to track where a majority of microplastics come from in the first place? Surprisingly, initial methods to keep tabs on such things rely on reports from plankton trawlers, according to a new report from the University of Michigan, and those same researchers have introduced the use of some far more advanced machinery for their work: satellites.
The new tracking method employed by the UM team is taking data from a system of eight micro-satellites that were launched in 2016 to track storms. Creating measurements for what they’re calling “ocean surface roughness,” they were able to find a correlation between radar measurements used to track wind speed and the existing data from plankton trawlers and ocean current models already used to predict the movement of microplastics.
“Areas of high microplastic concentration, like the Great Pacific Garbage Patch, exist because they’re located in convergence zones of ocean currents and eddies. The microplastics get transported by the motion of the water and end up collecting in one place,” says Chris Ruf, the Frederick Bartman Collegiate Professor of Climate and Space Science at UM. “Surfactants behave in a similar way, and it’s very likely that they’re acting as sort of a tracer for the microplastics.”Advertisement
One of the team’s headline-making findings with this new tracking method is that concentrations of microplastics in a body of water can vary by season. For example, the Great Pacific Garbage Patch shrinks to its smallest size in January, the thick of the Northern Hemisphere winter. Six months later, microplastic concentrations are at their highest in the exact same region come summer. Meanwhile, the same cycle is flipped in the Southern Hemisphere. The researchers’ hope is that straightforward data like this can direct an organization like the Ocean Cleanup, helping them know when and where to deploy their resources. The same discovery also helped UM researchers narrow down some of the greatest sources of microplastic flow into the ocean, like China’s Yangtze River.
“It’s one thing to suspect a source of microplastic pollution, but quite another to see it happening,” Ruf said. “The microplastics data that has been available in the past has been so sparse, just brief snapshots that aren’t repeatable.”
Next up, the researchers are testing hypotheses from their findings and conducting experiments in a wave-generating tank to learn the relationship between surface roughness and the presence of microplastics. Small wins that they hope add up to big gains in fighting a gigantic environmental problem.

Seabird eggs contaminated with plastic additives – study

Herring gull eggs have been found to be contaminated with chemical additives used in plastic production, researchers said.A study looked for evidence of phthalates – a group of chemicals added to plastics to keep them flexible – in newly laid herring gull eggs.The research by the universities of Exeter and Queensland found up to six types of phthalate per egg.The chemicals function as pro-oxidants – potentially causing oxidative stress that can damage cells.Unfortunately, our findings suggest that mothers are inadvertently passing on phthalates and products of lipid damageREAD MOREProfessor Jon Blount, of the Centre for Ecology and Conservation at the University of Exeter’s Penryn Campus in Cornwall said: “Herring gull mothers pass on vital nutrients to their offspring via their eggs.“This includes lipids that nourish developing embryos, and vitamin E, which helps to protect chicks from oxidative stress that can occur during development and at hatching.“Unfortunately, our findings suggest that mothers are inadvertently passing on phthalates and products of lipid damage – and eggs with higher phthalate contamination also contained greater amounts of lipid damage and less vitamin E.”The researchers say the impact of their findings on developing chicks is not yet known, and further research is needed.They collected 13 herring gulls eggs from sites in Cornwall and all 13 were found to contain phthalates.Phthalates – which are used in most plastic products and readily leech out – can build up in living organisms by becoming concentrated in fatty tissues.While the study does not show where the gulls acquired the phthalates, they have been previously found in species preyed on by herring gulls, and the birds are known to swallow plastic.More research is now needed to discover how developing offspring are affected by being exposed to phthalates before they have even emerged as a hatchlingProf Blount said: “Research on the impact of plastic on animals has largely focused on entanglement and ingestion of plastic fragments.“Far less is known about the impacts of plastic additives on the body.“By testing eggs, our study gives us a snapshot of the mother’s health – and it appears phthalate contamination could be associated with increased oxidative stress, and mothers transfer this cost to their offspring via the egg.“More research is now needed to discover how developing offspring are affected by being exposed to phthalates before they have even emerged as a hatchling.”The study received an initiator grant from QUEX, and is published in the journal Marine Pollution Bulletin.

Cape Cod, New Bedford salt marshes contain microplastics, study finds

NEW BEDFORD — Walk by a salt marsh and you’ll see tall grasses, a glassy water surface and perhaps a few local bird species. By sight alone, the marsh may appear to be in its natural state.According to a new study, though, some marshes — built up for years and years by layers of sediment — contain countless plastic fragments and fibers under their surfaces, some so tiny they’re only visible through a microscope. Javier Lloret, a research scientist at the Marine Biological Laboratory in Woods Hole and a lead author, said the study is the first step in considering what implications microplastics have for salt marshes. “Humans are the ones producing these plastics that ultimately will break up into little tiny pieces, become microplastics and contaminate our environment,” Lloret said. “So one of the hypotheses that we started with was the idea of, if you have more people living in an area, if the area is more densely urbanized, the salt marshes in that area are going to have more microplastics in the sediment. It makes total sense from a common sense point of view, but it had not been tested yet.”And that’s what they found: the more urbanized the surrounding land was, the more microplastic fragments they found in the salt marsh sediment.For the study, researchers took sediment cores from salt marshes in Cape Cod and New Bedford. Each marsh had a different level of watershed development and population density, with the New Bedford site being the most urbanized. Keeping the environment clean:Volunteers collect trash in Fairhaven. Next, they’ll mail some back to the companies.While they found microplastic fragments and fibers in all sampling sites, they found a link between the number of fragments and level of urbanization. Specifically, the abundance of microplastic fragments in sediment samples increased as the degree of urban development on adjoining land increased.What was consistent across sites, though, was the amount of microplastic fibers — the material released from synthetic clothing or fishing gear. Regardless of the level of urbanization, fibers were equally abundant in the samples, Lloret said.Due to this distinction, Lloret believes fragments have a local source, whereas fibers may be sourced from the region as they can be transported more easily by wind or water. Reconstructing the history of microplasticsAt two of the Cape Cod sites, the scientists took deeper sediment cores to trace when plastic started appearing in the salt marsh. About 30 centimeters deep took them to the early 1940s, Lloret said, when plastic was rare and not widely used. While studying the cores, they found the number of microplastics increased dramatically closer to the surface.Salt marsh restoration:Climate change creates stress for homeowners battling erosion on Cape Cod”In the last 25 years, the number of [plastic] particles you find in the sediments was doubled,” he said. “If we continue these trends, in just a matter of another decade we can have a lot more microplastics, and the impacts that we’re still trying to figure out can be even worse.” What does this mean for salt marshes?Salt marshes are important ecosystems. They provide habitats for numerous species (including shellfish some people enjoy eating), protect coastlines against storm surges and sea level rise, and sequester carbon, Lloret said. They also act as effective “sinks,” with the grasses capturing materials — be it plant matter, dirt or plastic — and depositing it on the base of the marsh.’Drowning in place’: Mass Audubon begins work to protect Dartmouth salt marshLloret said this study was just the first step. It confirmed salt marshes contain microplastics and that levels are linked to human activity. However, the “million dollar question” that remains is what the presence of microplastics means for the health and functionality of the ecosystem. Filter feeders like mussels and clams don’t differentiate between a particle of food or a microplastic, Lloret said. If they consume plastic, it can affect their health as well as that of human consumers. “I’m very interested in the effects that it’s going to have in the food web, because those food webs are responsible for the functioning of the entire ecosystem,” he said. “That’s the kind of direction that I would like to go with this.” Until he and other researchers untangle those big questions, Lloret said municipalities and the state can consider actions, such as educating residents on recycling or establishing regulations that bar certain synthetic materials. The bottom line, though, is trying to use less things that are made of plastic, he said. Standard-Times reporter Anastasia E.

Plastic recycling could be more dangerous than you think

Efforts to end plastic pollution with recycling could leave people and the environment laden with poisonous chemicals, a new study has found. The report, which was not peer-reviewed, assessed four recycling and plastic waste management techniques that are poised to become more common as countries, including Canada, try to reduce plastic pollution. It found the main solutions promoted by the plastic industry — recycling, incineration, and transforming plastic into fuel — will increase people’s risk of exposure to a cocktail of toxic chemicals. Most plastic products contain toxic chemicals added to give plastic desirable traits, like flexibility or non-stick properties. When they are broken down during recycling or incineration, these toxins — everything from endocrine disrupters to cancer-causing chemicals — can escape recycling facilities and landfills to contaminate people and the environmentGet top stories in your inbox.Our award-winning journalists bring you the news that impacts you, Canada, and the world. Don’t miss out.“It doesn’t matter which of those methods you choose. The toxic additives in plastic are creating exposure to the point where it’s a detriment to human health,” said Lee Bell, report co-author and policy adviser on persistent organic pollutants to the International Pollutant Elimination Network (IPEN), an international coalition of environmental organizations that produced the study. That problem is exacerbated by recycling and other waste management techniques. For instance, chemical recycling — a suite of processes that break plastic down into its molecular components to make new products — produces a sludge of concentrated toxins. Techniques that transform plastic into fuel or to burn it to produce heat or electricity have similar issues, the report notes. The sludge or ash produced during these processes is typically put in landfills, used in landscaping or road construction, or spewed directly into the environment. Bell explained that, over time, these toxins end up leaching into the environment and contaminating soil, water, and the food chain. What people are reading Mechanical recycling — a common technique where old plastic is shredded and melted into new products — also concentrates toxic additives in the new products. Beyond the dangers the final products present to human health, the technique is expensive and struggles to compete with new plastics, Bell said. The problem is poised to get exponentially worse, with oil and gas companies anticipating that plastic production will make up the bulk of their future growth as the world transitions away from fossil fuels. Annual global plastic production is expected to more than quadruple in the next 30 years to reach 1.8 billion tonnes in 2050, according to the report. “That production schedule will swamp any attempts to deal with (plastic waste) from a recycling perspective,” Bell said. “The only way you can try to bring that into some sort of equilibrium is to try and cap production.”Yet countries have been reluctant to curb production.For instance, earlier this year, Canada listed plastic as toxic under its primary environmental law. The move was the first step in the federal government’s proposed plan to end plastic waste. Under the proposal, some single-use items would be banned and other restrictions implemented to boost Canada’s recycling capacity roughly six-fold by 2030. Efforts to end plastic pollution with recycling could leave people — and the environment — laden with poisonous chemicals, a new study has found. #Plastics Only about nine per cent of Canada’s plastic is recycled, mostly using mechanical recycling, according to a 2019 study commissioned by Environment and Climate Change Canada (ECCC). The remainder goes to landfills, is incinerated, or leaks into the environment. However, despite the decision to list plastic as toxic, the Trudeau government has yet to limit plastic production. “(ECCC) is working…to implement a comprehensive agenda for zero plastic waste by 2030. We are also taking action to develop recycled content standards and to hold producers responsible for their plastic waste. This approach seeks to transition Canada away from a linear economy that disposes of plastic as waste, and towards a circular economy that keeps plastic in the economy and out of the environment… Proposed regulations to prohibit or restrict certain harmful single-use plastics will be published for public comment later this year,” said Moira Kelly, press secretary to Environment Minister Jonathan Wilkinson, in a statement.“Unless we have a global treaty that limits plastic production in the same way the Paris Agreement seeks to limit carbon emissions, we are not going to be able to come up with a circular economy,” Bell noted. In a circular economy, plastic couldn’t contain toxic additives to make it more easily recyclable. It would also need to be limited to medical devices and other essential uses. “I don’t think it’s that far away, but we’re being held up by the petrochemical and fossil fuel companies from reaching that point,” he said. “The one thing they don’t want to hear is limits on production because if they can’t use (oil) as fuel and they can’t pump it into plastics production, they’ve got a problem.”
