AB  - This review summarizes current understanding of how climate change-driven 
      physical and ecological processes influence the levels of persistent organic 
      pollutants (POPs) and contaminants of emerging Arctic concern (CEACs) in Arctic 
      biota and food webs. The review also highlights how climate change may interact 
      with other stressors to impact contaminant toxicity, and the utility of modeling 
      and newer research tools in closing knowledge gaps on climate change-contaminant 
      interactions. Permafrost thaw is influencing the concentrations of POPs in 
      freshwater ecosystems. Physical climate parameters, including climate oscillation 
      indices, precipitation, water salinity, sea ice age, and sea ice quality show 
      statistical associations with POPs concentrations in multiple Arctic biota. 
      Northward range-shifting species can act as biovectors for POPs and CEACs into 
      Arctic marine food webs. Shifts in trophic position can alter POPs concentrations 
      in populations of Arctic species. Reductions in body condition are associated 
      with increases in levels of POPs in some biota. Although collectively 
      understudied, multiple stressors, including contaminants and climate change, may 
      act to cumulatively impact some populations of Arctic biota. Models are useful 
      for predicting the net result of various contrasting climate-driven processes on 
      POP and CEAC exposures; however, for some parameters, especially food web 
      changes, insufficient data exists with which to populate such models. In addition 
      to the impact of global regulations on POP levels in Arctic biota, this review 
      demonstrates that there are various direct and indirect mechanisms by which 
      climate change can influence contaminant exposure, accumulation, and effects; 
      therefore, it is important to attribute POP variations to the actual contributing 
      factors to inform future regulations and policies. To do so, a broad range of 
      habitats, species, and processes must be considered for a thorough understanding 
      and interpretation of the consequences to the distribution, accumulation, and 
      effects of environmental contaminants. Given the complex interactions between 
      climate change, contaminants, and ecosystems, it is important to plan for 
      long-term, integrated pan-Arctic monitoring of key biota and ecosystems, and to 
      collect ancillary data, including information on climate-related parameters, 
      local meteorology, ecology, and physiology, and when possible, behavior, when 
      carrying out research on POPs and CEACs in biota and food webs of the Arctic.
