Where It Comes From
PFOS replacement in textiles/leather/paper treatments, cleaning products, and metal‑plating mist suppressants; releases from manufacturing and products can reach water [1][2].
How You Are Exposed
Drinking contaminated water, eating affected fish/food, indoor dust and treated goods, and workplace contact where PFAS are used [1][3].
Why It Matters
Less bioaccumulative than long‑chain PFAS but can affect thyroid hormones, kidneys, and development; EPA’s lifetime drinking‑water health advisory for PFBS is 2,000 ng/L [1][2].
Who Is at Risk
People on PFAS‑impacted private wells, PFAS‑using workers, pregnant people and infants, and those with thyroid or kidney disease [1][3].
How to Lower Your Exposure
Test well water; use certified activated carbon or reverse‑osmosis filters (NSF/ANSI 53 or 58); follow fish advisories; choose PFAS‑free products; wet‑dust/vacuum; follow workplace protections [2][3].
