Eating One US Fish Is Equivalent To Drinking a Month's Worth of
Contaminated Water, Study Finds

An anonymous reader quotes a report from CBS News:

Eating one freshwater fish caught in a river or lake in the United
States is the equivalent of drinking a month's worth of water
contaminated with toxic "forever chemicals," new research said on
Tuesday. The invisible chemicals, called PFAS, were first developed
in the 1940s to resist water and heat and are now used in items such
as non-stick pans, textiles, fire suppression foams and food
packaging. But the indestructibility of PFAS, per- and
polyfluoroalkyl substances, means the pollutants have built up over
time in the air, soil, lakes, rivers, food, drinking water and even
our bodies. There have been growing calls for stricter regulation
for PFAS, which have been linked to a range of serious health issues
including liver damage, high cholesterol, reduced immune responses
and several kinds of cancer.

To find out PFAS contamination in locally caught fish, a team of
researchers analyzed more than 500 samples from rivers and lakes
across the United States between 2013 and 2015. The median level of
PFAS in the fish was 9,500 nanograms per kilogram, according to a
study published in the journal Environmental Research. Nearly three
quarters of the detected "forever chemicals" were PFOS, one of the
most common and hazardous of the thousands of forms of PFAS. Eating
just one freshwater fish equalled drinking water with PFOS at 48
parts per trillion for a month, the researchers calculated. Last
year, the Environmental Protection Agency lowered the level of PFOS
in drinking water it considers safe to 0.02 parts per trillion. The
total PFAS level in the freshwater fish was 278 times higher than
what has been found in commercially sold fish, the study said. "This
study is important because it provides the first evidence for
widespread transfer of PFAS directly from fish to humans," said
David Andrews, a senior scientist at the non-profit Environmental
Working Group, which led research. He's calling for much more
stringent regulation to bring an end to all non-essential uses of
PFAS.

The new findings appear in the journal Environmental Research.
