Although PFAS have been used extensively since the 1950s, experts are only beginning to understand their potential impacts on human health. This understanding continues to evolve based on ongoing research. Two of the most studied PFAS chemicals are perfluorooctane sulfonate (PFOS) and perfluorooctanoate (PFOA). Current studies suggest that exposure to high levels of PFOS and PFOA may:
- increase cholesterol;
- decrease antibody response;
- decrease fertility in women;
- increase the risk of certain types of cancer; and
- increase the risk of thyroid diseases.
Scientists are still learning about the health effects from exposures to mixtures of PFAS. For more information, visit the CDC's PFAS and Your Health website and the Wisconsin Department of Health Services (DHS) PFAS webpage.
