AB  - Climate change may affect temporal trends of persistent organic pollutants (POPs) 
      in Arctic wildlife. We studied how biological and climate variables influence 
      temporal trends of selected POP groups in landlocked Arctic char muscle and in 
      ringed seal blubber from West and East Greenland. The variables included fish 
      length or animal age, sex, a stable nitrogen isotope, sea ice extent, air or 
      seawater temperature, salinity and the Arctic Oscillation Index (AOI). Model 
      selection for multiple regression showed that the most important predictors 
      varied among POP groups, species and region. Decreasing time trends were found 
      for all POP groups with the exception of hexachlorobenzene (HCB) concentration 
      which remained stable in Arctic char and ringed seals from West Greenland. When 
      retained in the most parsimonious model, the AOI was positively associated with 
      POP concentrations for East Greenland seals, but negatively for West Greenland 
      seals. Seawater temperature and sea ice extent were positively associated with 
      POP concentrations. The effects of explanatory variables on the annual rates of 
      change in POP concentrations were relatively minor relative to the decline caused 
      by reduction in POP emissions following national and international regulations 
      introduced since the 1970s.
