1-Heptanesulfonic acid, 1,1,2,2,3,3,4,4,5,5,6,6,7,7,7-pentadecafluoro-, compd. with 2,2'-iminobis[ethanol] (1:1)

PFAS production and use (surfactants, specialty lab chromatography reagents), metal plating operations, and areas affected by PFAS-containing firefighting foams (airports, military bases) [1][2].

Drinking contaminated water, eating contaminated fish/food, indoor dust, and workplace or lab handling. Private wells near impacted sites are a common route [1][2].

PFAS are very persistent and some can accumulate in the body. Studies link PFAS exposure with increased cholesterol, reduced vaccine response, liver enzyme changes, pregnancy hypertension, and developmental effects; some PFAS (e.g., PFOA) are carcinogenic [1][2][3]. Data on this specific salt are limited, so concerns are based on the PFAS class [1][2].

People using private wells near contaminated sites; firefighters and workers in PFAS manufacturing, metal plating, or labs; pregnant people, infants, and those who eat locally caught fish from affected waters [1][2].

Use alternate water or certified filters (activated carbon or reverse osmosis) for PFAS, test private wells, follow local fish/water advisories, reduce dust with wet-cleaning/HEPA, and follow workplace PPE and hygiene [1][2][4].
