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).
