Speaker: Tom Danielson, Aquatic Toxicology Unit, Maine Department of Environmental Protection
Per- and polyfluoroalkyl substances (PFAS), also known as “forever chemicals”, is a group of man-made chemicals that can be toxic and remain in the environment for a very long time. Some kinds of PFAS bioaccumulate in freshwater fish, often reaching hundreds to thousands times more in fish tissue than the water. The Maine Department of Environmental Protection collects fish tissue samples and provides information to the Maine Center for Disease Control and Prevention to establish safe eating guidelines for freshwater fish.
