Millions of children in the U.S. are being exposed to deadly polychlorinated biphenyls, or PCBs, in their schools, despite the fact that such chemicals have been banned for decades.
That's according to a new report from Sen. Ed Markey (D-Mass.) that analyzed Harvard research and Environmental Protection Agency (EPA) data, and which also uncovered a dismal lack of regulation around the illegal chemicals in school buildings.
PCBs are industrial chemicals so toxic that they were banned by Congress 40 years ago.
"PCBs are some of the most toxic and persistent chemicals ever produced," said Ken Cook, president of the Environmental Working Group (EWG), which analyzed the data on PCBs in Sen. Markey's report. "It's shocking to find that while they were banned decades ago, millions of kids and other Americans continue to be exposed today."
Indeed, EWG in a 2005 study found 147 different PCB contaminants in the umbilical cord blood of 10 American newborns.
