Cyclohexanesulfonic acid, decafluoro(pentafluoroethyl)-, potassium salt

Industrial PFAS manufacturing and use as surfactants and specialty coatings; releases can enter air and wastewater [2][4].

Drinking water, food, or household dust near PFAS production/use sites; workplace contact in fluorochemical industries or with firefighting foams [1][2].

PFAS persist and can build up in people. Some PFAS are associated with higher cholesterol, reduced vaccine response, liver effects, pregnancy-related high blood pressure, lower birth weight, and certain cancers (e.g., PFOA) [1][5].

Workers in PFAS manufacturing/processing and firefighters; people using contaminated private wells; pregnant people and infants are more sensitive to effects [1][2][5].

Use NSF-certified filters (granular activated carbon, reverse osmosis, or ion exchange) for drinking water; follow local water/fish advisories; reduce indoor dust with wet cleaning; at work, follow PFAS safety procedures and PPE [1][2][3].
