Where It Comes From
Releases from chrome plating operations and related wastewater; production and use of F‑53B PFAS alternatives to PFOS, especially in Asia [2][3].
How You Are Exposed
Drinking water near plating sites, eating contaminated fish, breathing or skin contact in workplaces, and household dust near affected industries [1][2][3][4].
Why It Matters
Very persistent and can accumulate in blood; studies show maternal transfer to the fetus and presence in breast milk; PFAS as a class are linked to immune, liver, thyroid, and lipid changes [1][2][4].
Who Is at Risk
Electroplating workers; people using private wells near plating facilities; pregnant people, infants, and high fish consumers [1][2][3].
How to Lower Your Exposure
Test private wells for PFAS; consider certified filters (granular activated carbon or reverse osmosis) if PFAS are detected; follow local fish advisories; use workplace PPE and hygiene to limit contact [2][5].
