Microplastics, small, micro-sized plastic fragments are showing up in our water sources, rain, drinking water, and beverages like beer. It is in food, salt, and seafood. Moreover, it has recently been found in human breast milk, placentas, human lungs, and blood. One report indicated that blue whales are consuming 10 million pieces of microplastic particles a day. As plastic fragments, it continues to shed fibers smaller than a strand of human hair. Most of the time we are unaware how and when this happens. Did you know, when you open a plastic cap on a bottle, you release thousands of particles. But then there is also our clothing, roads, artificial turf, food packaging, tea bags, or plastic that comes in contact with friction, hot liquid, or hot food. Dr. Scott Coffin [https://scottcoff.in/] joined us in this encore presentation from 2022. As a toxicologist and Research Scientist at California State Water Resources Control Board, he has been studying plastic since 2014. He speaks about how microplastics are entering our environment, what solutions are being put in place to assess risk and implement precautionary solutions, and how we might limit our own exposure. Dr. Scott Coffin is a research scientist and subject-matter expert for microplastics at the California State Water Resources Control Board, where he leads the agencys efforts to monitor and manage microplastics pollution in drinking water and the environment. Dr. Coffin holds a PhD in environmental toxicology from the University of California, Riverside.
