CHICAGO — Eating just one freshwater fish a year can dramatically increase the amount of toxic forever chemicals coursing through a person’s blood, according to a new study that reflects more than a half-century of pollution contaminating the Great Lakes and rivers nationwide.
The alarming finding is based on an analysis of hundreds of fish caught by the U.S. Environmental Protection Agency since 2013. Though the EPA has concluded some of the chemicals are harmful at any level, the agency hasn’t drawn attention to its fish sampling or warned Americans they could be in danger.
Nearly every fish tested by the EPA was tainted with perfluorooctane sulfonate or PFOS, a forever chemical used for decades in Scotchgard stain-resistant fabrics, firefighting foam and food packaging manufactured by Minnesota-based 3M.
