When people are exposed, PFAS can build up in the body. The amount of PFAS in the body can increase to the point where it can harm health. Studies have shown certain PFAS can cause negative health effects, including higher cholesterol levels, lower infant birth weights, weakened immune response, and increased risk of some cancers, including kidney cancer.
Infants and young children with developing immune systems; people who are breastfeeding, pregnant, or who may become pregnant; and people with weakened immune systems are particularly at risk.
