To address this problem,scientists are trying to understand how these chemicals get into thefood chain. Now, a scientist at Northwestern University has found alikely answer.

D-D-E May Degrade Naturally
The notorious pesticide D-D-T was banned in the United States in the 1970’s. But D-D-T left behind several toxic byproducts. One of those is D-D-E. However, a new study published in this month’s Science magazine suggests that D-D-E may be decaying naturally. The Great Lakes Radio Consortium’s Steve Frenkel reports:
Policing Ballast Water
Controlling exotic species in the Great Lakes hasn’t been easy. Scientists have been unable to slow the spread of things like the zebra mussel. But they still have a chance to prevent other non-native species from infesting Great Lake waters. The Great Lakes Radio Consortium’s Steve Frenkel reports on a potential breakthrough:
