Brazilian group presents novel method of analyzing microplastic pollution

Envirotec Magazine

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. Few studies of pollution by MPs have been published in Brazil, especially regarding inland aquatic areas.

Tannins: A possible answer to microplastic pollution?

Envirotec Magazine

Scientists at UBC’s BioProducts Institute find that if you add tannins to a layer of wood dust, you can create a filter that traps virtually all microplastic particles present in water, according to recently reported research. Most solutions proposed so far are costly or difficult to scale up.

Microplastics collect heavy metals, reports study from Ulaanbaatar

Envirotec Magazine

Surface cracks and biofilms on plastic particles might help spread pollution Concerns about microplastic pollution arise not only because of the particles themselves, but also from whatever cargo they might be carrying. Surface features such as holes and biofilms also increase this propensity to collect pollutants.

Study analyzes microplastics’ effect on clouds

Envirotec Magazine

A new study sheds light on the quantity and type of microplastics present in clouds. The researchers analyzed cloud water samples from high-altitude mountains in Japan to ascertain the amount of microplastics in them. Microplastics in the free troposphere are transported and contribute to global pollution,” said Okochi.

“Farming and rural land management,” he said, “impacts a higher proportion of our water bodies – 45% – than any other source, mostly through what is called diffuse pollution,” he said, referring to chemicals from things like fertilizers and pesticides, which run off the land and pollute water courses. An easier finger to point.

Graphene-based packaging presented as first truly biodegradeable and compostable alternative to plastic

Envirotec Magazine

While biodegradable plastics currently exist, they rely on commercial composting, which uses energy to heat the compost, as well as presenting other logistical challenges. It’s because they need specific manmade conditions to biodegrade, and many degrade into microplastics, which contaminate our oceans and food chain for centuries”.
