Recent research from The James Hutton Institute suggests that hidden threats from the agricultural use of contaminated sewage sludge could be contributing to already diminished poor soil health. The potential harmful effects of these unregulated contaminants on soils have been understudied in recent years.
Nano- and microplastics are seemingly everywhere — water, soil and the air. As reported in ACS’ Environmental Science & Technology Letters , boiling and filtering calcium-containing tap water could help remove nearly 90% of the nano- and microplastics present. Image credit: Eddy Zeng.
The last decade has seen some progress with studying plastic pollution, but there are still significant challenges, such as a lack of comparability of reported results, especially when it comes to microplastic particles. We measure particle size in all samples.
A research group in Japan has demonstrated that airborne microplastics adsorb to the epicuticular wax on the surface of forest canopy leaves, and that forests may act as terrestrial sinks for airborne microplastics The study used a new technique to measure the levels of microplastics adhering to the leaves.
Geoscience technology firm CGG has conducted a microplastics pollution survey as part of a scoping study into whether it would be possible to create a “Plastic Free zone” on Yr Wyddfa (Snowdon). On Yr Wyddfa (Snowdon), microplastic content was naturally highest where people congregate in large numbers.
While many previous reports had documented the buildup of plastic bottles and bags in the natural environment, much less attention had been paid to what the scientists dubbed “microplastics.” One thing that has become much clearer since the early 2000s is the sheer extent of microplastic pollution.
The campaign group, Fighting Dirty, has launched legal action against the Environment Agency (EA) and the Secretary of State for the Environment, Food and Rural Affairs, over a lack of testing for microplastics and harmful ‘forever chemicals’ in sewage sludge spread on land. The group announced the action on 2 November.
Microplastics are everywhere: We know that much. Even the definition of “microplastics” is slippery. Rivers, for example, though we would expect this to be a catchment-specific issue, said David Tompkins, a soil scientist with Aqua Enviro, during the November event. And not all rivers carry the same load of microplastics.
“It shows that the ocean is not only a sink but also a source of microplastics,” Melanie Bergmann, a marine ecologist who was not involved in the study, told Grist in an email. Steve Allen said that the same process of microplastic ejection is likely happening out at sea, and in other bodies of water like rivers and lakes.
The meat you buy in the store may be contaminated with microplastics. A recent study by Free University of Amsterdam found microplastics in the bloodstreams of pigs and cows for the first time. According to Dr. According to Dr. Leslie, microplastics in the soil likely found their way into crops eaten by animals.
All materials do this, even plastics, which break down into what we call microplastics – i.e. plastic particles smaller than 5mm. Biodegradable Straws Reduce Microplastics at Sea and on Land. We call these microplastics – and they have reached some of the most remote parts of the world. As such, it’s not a very precise term.
Specialist laboratory analysis has been carried out, focussing on microplastic analysis and dewaterability of digestates derived from food waste processes. It is said to comprehensively report key positive and negative characteristics of UK digestates produced from different feedstock types.
The tire particles pollute air, water, and soil and contain a wide range of toxic organic compounds, including known carcinogens, the analysts say, suggesting tire pollution could rapidly become a major issue for regulators. “By Other recent research has suggested tire particles are a major source of the microplastics polluting the oceans.
By diverting plastic waste from landfills and oceans, this process can mitigate: Soil contamination Leachate production Marine pollution The reduction in microplastics entering the food chain would have positive implications for both marine life and human health.
Preserving our soils, forests, and ecosystems is vital to sequestering carbon and feeding a growing population. Climate Robotics is developing advanced robotics to sequester carbon and improve soils. Matter is pioneering ways to capture, harvest, and recycle microplastics in wastewater. Build regenerative land and food systems.
And even then, the bags only break down to remain as microplastics that accumulate within the food chain. As already mentioned, once in the environment, plastic bags take up to 1,000 years to break down, and when they do break down, the microplastic byproducts remain in the environment and accumulate up the food chain.
Under natural conditions, plastics break apart into tiny pieces, known as microplastics , which pollute water supplies and are ingested by both wildlife and humans. Unlike biodegradables that can sometimes leave behind useless metal residues, compostable materials are designed to release nutrients and add value to soil once they break down.

Nitrogen and phosphorous are both essential for plant growth, thus they are made into fertilizers that pollute waterways and coastal zones, and accumulate in the world’s soil and land. The wetting could result in more vegetation or greening of the region, in what would be a rare example of a positive tipping point.
Detecting microplastics in wastewater. Call it ‘soil’ power, a new fuel cell can harvest energy from soil microbes. The alliance aims to promote policies and public sector procurement of green building materials. Pop-up Another week, another fusion deep-dive. AI’s newest catch?
What makes this particularly worrisome is that humans can be exposed to endocrine-disrupting chemicals simply by touching plastic, inhaling microplastics within dust, and eating food or drinking water that has been in contact with plastic. Those facing the greatest risk tend to be residents of low-income communities and people of color.
This contamination of water has spread PFAS to soil, crops and wildlife, including fish.“For The EPA uses what’s known as draft Method 1633 to test for up to 40 PFAS compounds in fish tissue, as well as in wastewater, surface water, groundwater, soil, biosolids, sediment and the liquid that forms when waste breaks down in landfills.
However, the farming sector can tackle micropollutants by minimising runoff through cover cropping and soil conservation, and optimising pesticide management to reduce leaching and emissions. Farming and agriculture Agriculture can contribute to micropollutant contamination in several ways, primarily via the use of pesticides.
The pandemic is still raging, the Arctic is burning up , and microplastics are polluting every corner of the Earth , but do try to take a deep breath. By contrast, the lush rainforests to the south of the Sahara have trees that both block the wind and hold on to the soil with their roots, keeping all the muck from taking to the air.
But agriculture can also be a carbon sink, where carbon is stored (sequestered) in both crops and soil. On some of the beaches in Hawaii’s Big Island, as much as 15% of the “sand” is actually grains of microplastic.
Because they are entirely plant-based, the pods are safe for the soil, leaving behind zero microplastics. After use, the pod is completely compostable when incorporated with other industrial compost. That means the pods need to go into municipal compost bins for proper processing.
Meanwhile new threats are seeping into our waters, including microplastics and so-called forever chemicals. We are still seeing too much pollution from sources we have known about for years: sewage, farming, industry and road-run off. Campaigners are right to be saying that this is not good enough.
Through his passion for the outdoors, he witnessed the effects of microplastic pollution on the environment. When Fionn was in high school, he invented a new method of extracting microplastics from the water using his own version of ferrofluid, a liquid developed by NASA. So here I am." Loukina Tille is from Switzerland. "We
