EPA PFAS Toxicity Assessments

EPA has developed toxicity assessments as part of the human health risk assessment process to summarize potential health effects associated with a chemical and exposure levels at which those health effects might occur. This webpage includes toxicological reviews and human health toxicity assessments and/or values for a number of PFAS, including PFOA, PFOS, PFBS, PFBA, PFHxA, PFDA, PFPrA, and GenX Chemicals.
