Organochlorine contaminants in ringed seals (Phoca hispida) of the western Canadian Arctic

Ringed seals are harvested by members of the Hunters and Trappers Committee at Ulukhaqtuuq (formerly Holman, NT) on an annual basis. Tissue samples from 13-20 seals per year in 1993, 1995 and 2002-2005 were chemically analyzed in laboratories in Winnipeg, MB. Sex and morphometric measurements of the seals were recorded in the field. Organochlorine concentrations from blubber, including pesticides and PCBs, were analyzed with gas chromatography and electron capture detection at the Freshwater Institute (Fisheries and Oceans Canada), Winnipeg, MB. Stable isotope ratios of nitrogen and carbon from lipid-extracted muscle tissue were analyzed with continuous flow ion ratio mass spectrometry at the University of Winnipeg Isotope Laboratory. Sea ice parameters were measured from Canadian Ice Service ice charts at the Institute of Ocean Science, Sidney, BC.
