Regulatory Action on PFAS/LCPFAC Compounds


In addition to its activities on PFOA, EPA has also been investigating and taking regulatory actions on other related perfluorinated compounds, including perfluoroalkyl sulfonates (PFAS). Studies have found PFAS chemicals in very small amounts in the blood of the general human population as well as in wildlife.

PFAS and long-chain perfluoroalkyl carboxylate (LCPFAC) chemical compounds are related. Although most of the health and environmental studies have focused primarily on PFOS and PFOA, analysis of the structure of these compounds indicates that the results of those studies may be applied to a larger category of PFAS and LCPFAC chemicals. EPA believes that the chemical similarity between PFOS and PFAS raises the likelihood that health and environmental concerns are present for PFAS, and that LCPFAC compounds may degrade to PFOA.
