 DDT Found in Penguins Due to Melting Glaciers
The pesticide DDT was banned in much of the world in the 1970's, but Adélie penguins today carry the same levels as the species did 30 years ago, when DDT was heavily used world-wide for insect control. Research conducted by Ecosystems Center scientist Hugh Ducklow and his graduate student Heidi Geisz....More>>>
