Where It Comes From
Specialty industrial and lab uses of PFAS; can act as a source of PFOA in the environment [1].
How You Are Exposed
Drinking water near PFAS production or use sites, firefighting foam areas, food, indoor dust, and some workplaces handling PFAS [1][4][5].
Why It Matters
PFOA is associated with decreased vaccine response, elevated cholesterol, liver effects, pregnancy-induced hypertension, reduced birth weight, and increased risk of kidney and testicular cancer [1][2][3].
Who Is at Risk
Workers in PFAS industries, communities near fluorochemical plants or firefighting training sites, pregnant people, infants fed reconstituted formula in affected areas, and high consumers of contaminated fish or water [1][4][5].
How to Lower Your Exposure
Use certified filters (activated carbon or reverse osmosis) for PFAS, check local water reports and fish advisories, reduce dust with wet cleaning, limit products advertised as stain‑ or water‑resistant when possible, and follow workplace safety controls [1][4][5].
