Understanding Risk to Wildlife from Exposures to Per- and Polyfluorinated Alkyl Substances (PFAS) provides the most recent summary of toxicity data relevant to mammals, birds, reptiles, and amphibians, and provides values for use in risk assessment applications. Predicting the bioaccumulation of PFAS in terrestrial wildlife (including humans) has proven to be extremely complex. As a group, PFAS act differently than traditional non-ionic organic molecules, where PFAS can break down and refo...
