Distribution of polybrominated diphenyl ethers and decabromodiphenylethane in surface sediments from the Bering Sea, Chukchi Sea, and Canada Basin
24 surface sediment samples were collected from the Bering Sea, Chukchi Sea, and Canada Basin during the 3rd Chinese National Arctic Research Expedition in July-September 2008. To obtain information on the levels, spatial distribution, possible sources, and influences of total carbon and black carbo...
