Estimation of Serum PFOA Concentrations from Drinking and Non–Drinking Water Exposures
Science
16 Jun 2023 | EHP
PFAS-contaminated sites should be remediated and drinking water containing PFAS should be treated; however, to achieve meaningful reductions in serum PFAS, a comprehensive national approach must be undertaken to reduce PFAS exposures from all sources, including banning PFAS in food, consumer products, and other nonessential uses.
