      Organochlorine Pesticides in Landlocked Char from Lakes in the Canadian High 
      Arctic.

AB  - Temporal trends and climate related parameters affecting the fate of legacy 
      persistent organic pollutants (POPs) such as polychlorinated biphenyls (PCBs) and 
      organochlorine pesticides (OCPs) were examined in landlocked Arctic char from 
      four lakes in the Canadian Arctic. Among biological parameters, lipid content was 
      a key factor explaining the concentration of most POPs in Arctic char. Legacy 
      PCBs and OCPs generally showed declining trends of concentrations in Arctic char, 
      consistent with past restriction on uses and emissions of POPs. However, 
      increases in lake primary productivity (measured as chlorophyll a) exerted a 
      dilution effect on POPs concentrations in Arctic char. Concentrations of POPs in 
      char from the last two decades were positively correlated with interannual 
      variations of the North Atlantic Oscillation (NAO). Higher concentrations of POPs 
      in Arctic char were observed in 3 of the 4 lakes during positive NAO phases. 
      This, together with increasing local Arctic temperatures, could lead to increases 
      on POPs concentrations in char from remote Arctic Lakes in future decades. Also, 
      if there are nearby secondary sources as may be the case for Resolute Lake, 
      located near an airport where increasing levels were found for hexachlorobenzene 
      and toxaphene, probably due to the mobilization from secondary sources in soils.
