Where It Comes From
Industrial uses such as metal plating/mist suppressants, water- and oil‑repellent processes, and some firefighting foams [2].
How You Are Exposed
Drinking contaminated water (especially near factories, airports, or fire‑training sites), indoor dust, eating contaminated fish, and certain jobs [1][2].
Why It Matters
Highly persistent and mobile. Data on this specific PFAS are limited, but related PFAS have been linked to higher cholesterol, changes in liver enzymes, reduced vaccine response, and developmental effects [1][3][4].
Who Is at Risk
Workers in metal plating and firefighting; people using private wells near industrial or firefighting areas; pregnant people, fetuses, and infants [1][2][4].
How to Lower Your Exposure
Test well water; use certified reverse‑osmosis or activated‑carbon filters for PFAS; follow local fish advisories; minimize use of stain‑/water‑resistant products; follow workplace controls and hygiene [1][2][4].
