Geographical distribution and identification of methyl sulphone PCB and DDE metabolites in pooled polar bear (Ursus maritimus) adipose tissue from western hemisphere arctic and subarctic regions.

Abstract

The geographical distribution of methyl sulphone (MeSO2-) PCB and DDE metabolites is unknown for any species in any region. In this study, pooled male polar bear (Ursus maritimus) adipose samples from 12 arctic and subarctic regions from the Bering Sea to the Greenland Sea were analyzed for PCBs, DDE, and their MeSO2-metabolites. Each adipose pool contained… (More)
