We analyzed 151 organohalogen chemicals (OHCs) in whole blood and subcutaneous fat of 57 polar bears sampled along the Alaskan Beaufort Sea coast in spring, 2003. All major organochlorine pesticides, PCBs, PBDEs and their congeners were assessed. Concentrations of most OHCs continue to be lower among Southern Beaufort Sea polar bears than reported for other populations. Additionally, toxaphenes and related compounds were assessed in adipose tissue, and 8 perflourinated compounds (PFCs) were examined in blood. Perfluorooctane sulfonate (PFOS) concentrations exceeded those of any other contaminant measured in blood. SigmaChlordane concentrations were higher in females, and both SigmaPCBs and SigmaChlordane concentrations in adipose tissue decreased significantly with age. The rank order of OHC mean concentrations; SigmaPCB>Sigma10PCB>PCB153>SigmaChlordane>Oxychlordane>PCB180>SigmaHCH>beta-HCH>SigmaDDT>p,p-DDE>SigmaPBDE>HCB>Toxaphene was similar for compounds above detection limits in both fat and blood. Although correlation between OHC concentrations in blood and adipose tissue was examined, the predictability of concentrations in one matrix for the other was limited.
