An alarming 5 percent of Pennsylvania children have elevated levels of lead in their blood at more than two times the national rate, a newly released study has found.
The research, from JAMA Pediatrics, a peer-reviewed medical journal published by the American Medical Association, puts Pennsylvania in the company of just six states nationwide with such dangerously high blood levels, according to the Ohio Capital Journal, a sibling site of the Pennsylvania Capital-Star, which published the results on Tuesday.
