What are the potential health effects of PFAS?

Research has shown that there may be health effects associated with exposure to some PFAS. Because there are many types of PFAS chemicals, which often occur in complex mixtures and in various everyday products, researchers face challenges in studying them. More research is needed to fully understand all sources of exposure, and if and how they may cause health problems. The National Institute of Environmental Health Sciences (NIEHS) provides updated information on health effects as well as a searchable database of published scientific papers about PFAS.
