1-Decanesulfonic acid, 1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-heneicosafluoro-, ammonium salt

Production and use of fluorinated surfactants in metal plating, water/oil‑repellent coatings, and some firefighting foams; releases via wastewater, spills, and wear of treated products [2].

Drinking contaminated water; eating affected fish or produce; indoor dust from treated carpets/upholstery; workplace air/skin contact; transfer during pregnancy and in breast milk [1][2].

Some PFAS—especially long‑chain types like PFOS/PFOA—are linked to higher cholesterol, liver enzyme changes, reduced vaccine response, developmental effects, and certain cancers; similar long‑chain sulfonates raise concern even when data are limited for this specific chemical [1][2][3].

People near contaminated water, firefighters and metal‑plating workers, those who eat a lot of locally caught fish/game, pregnant people, infants, and young children [1][2].

Check local water reports; consider certified carbon or reverse‑osmosis filters; follow fish/game advisories; avoid AFFF use; choose PFAS‑free products; damp‑dust/HEPA vacuum; use safe water for infant formula [1][2][4].
