"A persistent chemical formerly used in Scotchgard still contaminates most fish in U.S. rivers and the Great Lakes despite a phase-out a dozen years ago, a new federal study shows.

U.S. Environmental Protection Agency researchers found perfluorooctane sulfonic acid (PFOS) in all of the 157 fish sampled from nearshore waters in the five Great Lakes and in 73 percent from 162 rivers.

The study, the largest of its kind in freshwater fish, suggests that eating bass, trout, walleye and catfish could be a major source of exposure for anglers and their families. The chemical remains widespread in wildlife, people and water around the world."
