Where It Comes From
Fluorochemical manufacturing; treated textiles, paper/packaging, specialty coatings; releases via industrial wastewater, product wear, and landfills [1][2].
How You Are Exposed
Drinking water near impacted facilities; indoor dust from treated carpets/fabrics; some foods (fish, packaged foods); workplace air and skin contact [1][2].
Why It Matters
Some PFAS are linked to higher cholesterol, liver and thyroid changes, reduced vaccine response, pregnancy‑induced hypertension, lower birth weight, and certain cancers (PFOA: carcinogenic to humans) [1][3][4].
Who Is at Risk
Workers using PFAS; communities near manufacturing or firefighting‑foam use; people with private wells; pregnant people, infants, and children [1][2].
How to Lower Your Exposure
Check local water advisories; use NSF/ANSI 53 or 58 certified filters for PFAS; follow fish advisories; limit stain‑resistant/water‑repellent products labeled “fluoro‑”; wet‑dust/HEPA vacuum; follow workplace PPE and hygiene [1][2].
