PFAS and their health effects
The potential for health effects from PFAS in humans is not well understood. PFOS, PFOA, PFHxS and PFNA have generally been studied more extensively than other PFAS. In general, animal studies have found that animals exposed to PFAS at high levels resulted in changes in the function of the liver, thyroid, pancreas and hormone levels.
