Microplastics are all over the place, even in the most remote regions of the world. Where do these minute pieces of plastic originate from? Scientists from the University of Basel and the Alfred-Wegener Institute have demonstrated that it requires precise analysis to respond to this question. ....

The Microplastics And PFAS Connection By Cayla Cook and Eva Steinle-Darling Microplastics, small plastic particles with sizes ranging from 5 millimeters to 1 nanometer with various morphologies such as microfibers, fragments, pellets (nurdles), or microbeads, have received increasing attention, including upcoming statewide monitoring in California. Per- and Polyfluoroalkyl Substances (PFAS) are a group of unique chemically stable compounds and, as a result, have made them highly valuable across a wide range of industrial, commercial, and military uses. However, this feature concomitantly makes them recalcitrant and persistent in nature thus coined “forever” chemicals (Lindstrom et al. 2011, Buck et al. 2011). Recent developments in toxicology, coupled with significant political pressure, have put PFAS on the fast-track for regulation in drinking water and wastewater. While co-occurrence is well-known for a variety of contaminants like triclosan and triclocarban, ....
Deep-sea trench in the Pacific Ocean turns into a “plastic trap” Together with colleagues from the Alfred Wegener Institute and the Johann Heinrich von Thünen Institute, Senckenberg scientists Serena Abel and Angelika Brandt examined sediment samples from the Kuril-Kamchatka Trench for the presence of microplastics. In their study, which was recently published in the scientific journal “Environmental Pollution,” the researchers show that one kilogram of sediment contains between 14 and 209 microplastic particles. Overall, the team was able to document 15 different types of plastics in the samples. Humans produce more than 400 million tons of plastic each year – and the negative side effects of this are apparent in the form of plastic islands in the oceans and plastic waste in rivers, forests, and along roadsides. “Plastic remains can even be found in the deepest oceans,” explains Serena Abel of the Senckenberg Research Institute and Natural History Museum in ....
