AB  - Muscle samples were collected from pup, juvenile and adult Weddell seals 
      (Leptonychotes weddellii) near McMurdo Sound, Antarctica during the austral 
      summer of 2006. Blubber samples were collected from juvenile and adult seals. 
      Samples were analyzed for emerging and legacy persistent organic pollutants 
      (POPs) including current and historic-use organochlorine pesticides, 
      polychlorinated biphenyls (PCBs), and polybrominated diphenyl ethers (PBDEs). Of 
      the 41 target analytes, 28 contaminants were recovered from the Weddell seal 
      blubber, in this order of prevalence: p,p'-DDE, p,p'-DDT, trans-nonachlor, mirex, 
      cis-nonachlor, PCB 153, PCB 138, dieldrin, heptachlor epoxide, nonachlor III, PCB 
      187, oxychlordane, cis-chlordane, PCB 118, PBDE 47, PCB 156, PCB 149, PCB 180, 
      PCB 101, PCB 170, PCB 105, o,p'-DDT, PCB 99, trans-chlordane, PCB 157, PCB 167, 
      PCB 189, and PCB 114. Fewer POPs were found in the muscle samples, but were 
      similar in the order of prevalence to that of the blubber: p,p'-DDE, o,p'-DDT, 
      trans-nonachlor, nonachlor III, oxychlordane, p,p'-DDT, dieldrin, mirex, 
      cis-nonachlor, PCB 138, and PCB 105. Besides differences in toxicant 
      concentrations reported between the muscle and blubber, we found differences in 
      POP levels according to age class and suggest that differences in blubber storage 
      and/or mobilization of lipids result in age class differences in POPs. To our 
      knowledge, such ontogenetic associations are novel. Importantly, data from this 
      study suggest that p,p'-DDT is becoming less prevalent temporally, resulting in 
      an increased proportion of its metabolite p,p'-DDE in the tissues of this top 
      predator. In addition, this study is among the first to identify a PBDE congener 
      in Weddell seals near the McMurdo Station. This may provide evidence of increased 
      PBDE transport and encroachment in Antarctic wildlife.
