Study Says Global Warming Could Release DDT Deposits in Antarctica, Harm Wildlife

摘要

Global warming may contribute to continuing DDT contamination of some of Antarctica's wildlife as melting glaciers release deposits of the pesticide transported via the atmosphere decades ago, according to a group of researchers. "Our findings reveal an unexpected consequence of climate change and implicate glacier meltwater as a current source of DDT to the Antarctic marine food web," they said in a paper "Melting Glaciers, A Probable Source of DDT to the Antarctic Marine Ecosystem," scheduled to be published in the June 1 issue of Environmental Science and Technology.
