AB  - Temporal dynamics of persistent organic pollutants (POPs) were examined in 
      fasting common eider (Somateria mollissima) females in one subarctic (68 degrees  N; over 
      5 years) and one high arctic colony (78 degrees  N; 3 years). Blood concentrations of 
      polychlorinated biphenyl (PCB)-153; 1-dichloro-2,2-bis (p-chlorophenyl) ethylene 
      (p,p'-DDE), and hexachlorobenzene (HCB) were measured twice each season in eider 
      females (total n = 162) during incubation (at day 5 and day 20). The mean wet 
      weight concentrations of PCB-153 were ~3-5 times higher in the subarctic colony, 
      whereas p,p'-DDE and HCB concentrations tended to be higher in high arctic than 
      in subarctic eiders late in the incubation period. All POPs increased during 
      incubation fast, but the relative increase in mean concentration varied more 
      among years in high arctic than in subarctic eiders. In the high arctic, both 
      lipid-metabolism and the increase in circulating POP concentrations were highest 
      in the year when the mean ambient temperature was lowest. Moreover, females with 
      low body condition and high lipid metabolism (body mass loss) had stronger 
      increase in circulating concentrations of p,p'-DDE and HCB; the effect size being 
      within the same order of magnitude in the two colonies. Hence, since eiders at 
      high latitudes metabolized relatively more lipids, they experienced higher 
      exposure of p,p'-DDE and HCB over the incubation period than birds inhabiting the 
      more benign subarctic region.
