Where It Comes From
Made for fluorochemical manufacturing; used as a precursor to PFAS found in textiles, paper, and industrial processes [1][3].
How You Are Exposed
Mainly at work during manufacture or use; also from emissions or waste near facilities, and from contaminated drinking water, air, or dust. PFAS-treated products can add to overall PFAS exposure [1][2].
Why It Matters
Long‑chain PFAS don’t break down and can accumulate in blood. Exposure to some PFAS is linked to higher cholesterol, immune effects, liver and developmental changes, and other health impacts [1][2]. Data on this specific chemical are limited [1][3].
Who Is at Risk
Workers in fluorochemical plants; people using contaminated private wells or living near PFAS facilities; pregnant people, infants, and children [2].
How to Lower Your Exposure
Check local water advisories; use NSF/ANSI 53 or 58 certified filters (activated carbon or reverse osmosis); follow fish advisories; limit use of stain-/water‑repellent treatments; follow workplace protections [1][2][4].
