Eating just one freshwater fish is like drinking a month's worth of "forever chemical"–laced water

No one would willingly drink a cup of carpet coating, shampoo or eye makeup — and yet, many of us routinely eat food that

contains some of the same nasty chemicals. All of those aforementioned products contain a chemical called PFOS (short for perfluorooctane sulfonic acid) — which are in turn part

of a class of everyday chemicals known as PFAS (short for per- and polyfluoroalkyl substances) — and a new study in the scientific journal Environmental Research has disgusting

news: Eating just a single serving of freshwater fish is like drinking a month's worth of water laced with PFOS at harmfully high levels. "Eating one bass is equivalent to

drinking PFOS-tainted water for a month." Scientists from the activist organization Environmental Working Group (EWG) studied more than 500 fish fillets obtained

throughout the United States between 2013 and 2015. They found that eating just one fish from America's rivers and lakes in a single year was equivalent to regularly ingesting

water with PFOS at 48 parts per trillion (ppt) over the course of an entire month. More broadly, they found that the median level of PFAS in those fish fillets was 9,500 nanogram

per kilogram (ng/kg), with the median PFAS level shooting up to 11,800 ng/kg with fish from the Great Lakes. The United States Environmental Protection Agency (EPA) says that the

safe limits for PFAS in drinking water are much lower — specifically 0.02 parts per trillion for PFOS and 0.004 parts per trillion for PFOA (a different class of PFAS).
