Made and used in fluorinated surface treatments for textiles, paper/packaging, and some industrial processes (e.g., metal plating); can be released from treated products to air, dust, and water [1][2].

Breathing indoor air or dust from treated goods, using aerosol waterproofing sprays, skin contact with coated textiles, and drinking water or eating food contaminated with PFAS [1][3][4].

Long‑chain PFAS can build up in people; exposure is associated with immune effects (reduced vaccine response), increased cholesterol, liver and developmental effects; some related PFAS (e.g., PFOA) cause cancer in humans [1][3][5].

Workers making/using PFAS coatings; people with contaminated drinking water; pregnant people, infants, and children; households with many stain‑/water‑resistant items and high dust [1][3].

Choose PFAS‑free products; avoid aerosol waterproofers; improve ventilation; damp‑dust and use a HEPA vacuum; wash new textiles; use activated carbon or reverse‑osmosis filters certified for PFAS; follow local fish/game advisories [1][3][4].
