E-M:/ Great Lakes fishermen less contaminated than a decade ago

PCBs and DDT have declined substantially in Great Lakes anglers and boat captains over the past decade, largely because they switched the fish they eat.
Anglers who ate Great Lakes fish have 33 percent fewer PCBs and 43 percent less DDT in their bodies than they did a decade ago, largely because they changed their diet and switched to less contaminated fish, according to a study by Wisconsin researchers.
