Locally caught freshwater fish across the United States are likely a significant source of exposure to PFOS and other perfluorinated compounds
Science
27 Dec 2022 | Environ Res
PFAS are widely detected in freshwater fish across the United States at very high concentrations and fish may be a main source of exposure, especially for communities that depend on fish for sustenance and traditional cultural practices. For example, PFOS exposure from one average serving of freshwater fish is equivalent to one month of exposure from drinking water with 48 ppt PFOS.
