Description: Per- and Polyfluoroalkyl Substances (PFAS) list corresponds to a second set of 75 samples (Set 2) submitted for the testing screens conducted by EPA researchers in collaboration with researchers at the National Toxicology Program. The list of the first set of 75 samples (Set 1) can be accessed at EPAPFAS75S1. Substances for both Set 1 and Set 2 were selected based on a prioritization scheme that considered EPA Agency priorities, exposure/occurrence considerations, availability of animal or in vitro toxicity data, and ability to procure in non-gaseous form and solubilize samples in DMSO.
