What health effects should I be worried about?

Based on the EPA's review of the science, exposures to these four PFAS (PFOA, PFOS, GenX, PFBS) above the EPA health advisory levels can:

  • Decreased liver function
  • Decreased immune response and reduced vaccine effectiveness
  • Decreased birthweight, behavioral changes of infants and children
  • Increased risk of high blood pressure for pregnant women
  • Increased cholesterol levels
  • Increased risk of kidney and/or testicular

If you are concerned about specific issues with your health, talk with your healthcare provider. Information for health care providers is available from NCDHHS (PDF) and from the CDC's Agency for Toxic Substances and Disease Registry.

Human health effects from exposure to low environmental levels of PFAS are uncertain. Studies of laboratory animals given large amounts of PFAS indicate that some PFAS may affect growth and development. Epidemiologic studies on PFAS exposure evaluated several health effects. See descriptions of these studies. More research is necessary to assess the human health effects of exposure to PFAS. (Information is from the CDC.)
