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 soilhealth. 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. Plastic production and pollution affect human health and fuel greenhouse gas emissions.
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.
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. It turns out, they were right.
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. Certification schemes aim to provide some assurance that products like compost and digestate are safe for human, animal and plant health. Even the definition of “microplastics” is slippery. And not all rivers carry the same load of microplastics. But should we be worried?
“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.
All materials do this, even plastics, which break down into what we call microplastics – i.e. plastic particles smaller than 5mm. Yet, given the environmental impact of plastic straws , they don’t make sense for the health of our planet either. Biodegradable Straws Reduce Microplastics at Sea and on Land. ABOUT THE AUTHOR.
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.
While challenging, the impact on the environment, human health, and biodiversity warrants such an endeavor. Implementing such a system would require carefully designed infrastructure, stringent regulations, and public cooperation.
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. Other recent research has suggested tire particles are a major source of the microplastics polluting the oceans.
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. At the intersection of climate change and equity lies human health. 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.
Scientists know, for example, that at least 3,200 plastic chemicals pose risks to human health or the environment. more than $900 billion in health expenses annually. Because so many plastics and petrochemical products are traded internationally, some endocrinologists and public health authorities believe a global approach is needed.
Consumption of PFOS-contaminated freshwater fish can cause significant increases in peoples’ blood serum levels of the forever chemical, creating potential health risks. There should be a single health protective fish consumption advisory for freshwater fish across the country.” National EPA tests show nearly all fish in U.S.
In addition, some health services have takeback programmes for expired or unused medication, preventing them from being flushed down the drain or disposed of improperly. Pharmaceutical companies are collaborating with universities and research institutions to develop more environmentally friendly drugs and production processes.
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.
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 should remember though that rivers have never been maintained for human health but for wildlife and nature. Campaigners are right to be saying that this is not good enough. It is good that people are demanding better.
Here is a brief introduction to 50 young activists that fighting for the health of our planet and our communities. He is also concerned about health problems in black communities due to poor air quality. Through his passion for the outdoors, he witnessed the effects of microplastic pollution on the environment. So here I am."
