Where It Comes From
Making/using fluorinated surfactants and water‑ or oil‑repellent coatings; metal plating; some firefighting foams; releases from industrial wastewater, spills, and disposal; transformation of related PFAS [1][3].
How You Are Exposed
Drinking contaminated water; eating fish or food from affected areas; indoor dust and some treated products; workplace exposure where PFAS are used or made [1][2][3].
Why It Matters
PFAS persist in people and the environment. Some PFAS are linked to higher cholesterol, changes in liver enzymes, reduced vaccine response in children, and developmental effects; risk varies by specific PFAS and dose [1][2].
Who Is at Risk
People near PFAS production or metal‑plating sites, airports/fire‑training areas; workers handling PFAS; pregnant people, infants, and young children [1][2][3].
How to Lower Your Exposure
Check local water reports; consider home filters certified to reduce PFAS (granular activated carbon or reverse osmosis); follow fish/game advisories; wet‑dust and use a HEPA vacuum; avoid optional stain‑/water‑resistant treatments; follow workplace safety steps [2][3].
