AB  - Exposure to persistent organic pollutants (POPs) is a key factor in predicting 
      the collapse of global killer whale (Orcinus orca) populations due to 
      reproductive and immune impacts. Blubber biopsies from killer whales (n = 25) 
      were collected in the Russian Far East in 2002-2004. Biopsies were analyzed for 
      SigmaDDT, SigmaPCB, and HCB concentrations. A subset of biopsies was further examined for 
      additional contaminants, SigmaPBDE, SigmaHCH, SigmaCHLD, mirex, and dieldrin. Mean 
      concentrations were compared across resident (fish-eating) and transient 
      (mammal-eating) ecotypes and between sexes. SigmaPCB analytes (resident males 18,000, 
      resident females 1200, and transient males 420,000 ng g(-1) lw) and HCB (resident 
      males 750, resident females 81, and transient males 6200 ng g(-1) lw) differed 
      significantly (p < 0.001). No significant difference was observed between sexes. 
      Notable disparities in contaminant levels between ecotypes support the major 
      toxicological theories of contaminant bioaccumulation and dietary impacts on 
      individual contaminant load.
