Rainfall causes microplastic transport into the atmosphere

Up to 100 trillion microplastic particles could enter the atmosphere every year as a result of rainfall

22-Nov-2021

Oceans, lakes and rivers often contain a large number of microplastic particles on their surface. Impacting raindrops cause many droplets with an almost equally high concentration of microplastics to be thrown up into the air. When they evaporate in the air, the particles enter the atmosphere. ...

Detecting microplastics in the environment

Geochemist has developed a method to track microplastics in water, soil and even organisms

07-Oct-2021

Geochemist Denise Mitrano has found a way to track how micro- and nanoplastic particles spread through the environment. For this work, she is receiving this year's Marie Heim-Vögtlin Prize from the Swiss National Science Foundation. Man-made plastic pollutes the environment. When broken down into ...

Sunlight can break down marine plastic into tens of thousands of chemical compounds

13-Sep-2021

Sunlight was once thought to only fragment plastics in the marine environment into smaller particles that chemically resemble the original material and persist forever. However, scientists more recently have learned that sunlight also chemically transforms plastic into a suite of polymer-, ...

Microplastics: A Trojan Horse for Metals

Study shows that microplastics can serve as a transport vehicle for metals in the environment

11-Aug-2021

The fact that microplastics can accumulate organic pollutants from the environment and transport them has been known for some time. What is new, however, is that metals can also be transported in this manner. In addition, the smaller the particles, the greater the metal accumulation on the ...

Physicists prove that microplastics can damage cell membranes

04-Aug-2021

Over 70 million tonnes of microplastics are in the oceans. They are then ingested by marine life and humans through rain and airborne transmission. Two physicists, Jean-Baptiste Fleury of Saarland University and Vladimir Baulin of Tarragona University, have recently discovered that microplastics ...

Eco-friendly technology to produce energy from textile waste

Scientists from Lithuania proposed a method to convert lint-microfibers found in clothes dryers into energy

16-Jun-2021

A team of scientists from Kaunas University of Technology and Lithuanian Energy Institute proposed a method to convert lint-microfibers found in clothes dryers into energy. They not only constructed a pilot pyrolysis plant but also developed a mathematical model to calculate possible economic and ...

Nanoplastics – an underestimated problem?

Tiny plastic particles in the environment

06-May-2021

The images leave no one cold: giant vortices of floating plastic trash in the world's oceans with sometimes devastating consequences for their inhabitants – the sobering legacy of our modern lifestyle. Weathering and degradation processes produce countless tiny particles that can now be detected ...

It's snowing plastic

New technique detects minute particles of plastics in snow, rain and even soil

22-Mar-2021

The snow may be melting, but it is leaving pollution behind in the form of micro- and nano-plastics according to a McGill study that was recently published in Environmental Pollution. The pollution is largely due to the relatively soluble plastics found in antifreeze products (polyethylene ...

Eliminating microplastics in wastewater directly at the source

A research team has developed a process for the electrolytic treatment of wastewater that degrades microplastics at the source

22-Jan-2021

A research team from the Institut national de la recherche scientifique (INRS) has developed a process for the electrolytic treatment of wastewater that degrades microplastics at the source. The results of this research have been published in the Environmental Pollution journal. Wastewater can ...

Microplastics transport metallic pollutants

Pursuing the Trojan horse: Scientists are developing methods for measuring metal in microplastics

27-Jul-2020

There are a relatively large number of studies on the accumulation and transport of persistent organic pollutants by microplastics, which has resulted in good data in this regard. Data, however, on the accumulation of metals that are toxic to the environment are very rare and sometimes ...
