Impacts of PFOA and PFOS

PFOA and PFOS are widespread because they are persistent in the environment and do not readily break down when exposed to air, water, or sunlight. They can be found in air, soil, and water (both groundwater and surface water). PFOA and PFOS are also very persistent in the human body, and exposures to these chemicals are known to have a number of adverse effects in laboratory animals and humans. More information about the health impacts of PFOA and PFOS can be found in the links below.
