1,3-Propanediol, 2,2-bis[[(γ-ω-perfluoro-C4-10-alkyl)thio]methyl] derivs., phosphates, ammonium salts

Made for industrial uses such as treating textiles and paper/packaging and other surfactant applications; PFAS are very persistent and can transform into other PFAS in the environment [1][2].

Drinking water near industrial sites or firefighting areas; contact with treated products and indoor dust; workplace air/skin in manufacturing or firefighting; some food contact materials [1][2].

PFAS build up in the body. Some PFAS are linked to increased cholesterol, liver changes, reduced vaccine response, pregnancy-related high blood pressure, and certain cancers (e.g., PFOA is carcinogenic to humans) [1][3][4].

Workers handling PFAS or firefighting foams; people living near factories, airports, or military bases; pregnant people, infants, and children [1][2].

Check local water reports; consider certified filters (granular activated carbon or reverse osmosis); reduce use of stain‑/water‑repellent products; follow workplace safety guidance [1][2].
