TI  - Is Glacial Meltwater a Secondary Source of Legacy Contaminants to Arctic Coastal 
      Food Webs?

AB  - Climate change-driven increases in air and sea temperatures are rapidly thawing 
      the Arctic cryosphere with potential for remobilization and accumulation of 
      legacy persistent organic pollutants (POPs) in adjacent coastal food webs. Here, 
      we present concentrations of selected POPs in zooplankton (spatially and 
      seasonally), as well as zoobenthos and sculpin (spatially) from Isfjorden, 
      Svalbard. Herbivorous zooplankton contaminant concentrations were highest in May 
      [e.g.,  summation operatorpolychlorinated biphenyls ((8)PCB); 4.43, 95% CI: 2.72-6.3 ng/g lipid 
      weight], coinciding with the final stages of the spring phytoplankton bloom, and 
      lowest in August ( summation operator(8)PCB; 1.6, 95% CI: 1.29-1.92 ng/g lipid weight) when 
      zooplankton lipid content was highest, and the fjord was heavily impacted by 
      sediment-laden terrestrial inputs. Slightly increasing concentrations of 
      alpha-hexachlorocyclohexane (alpha-HCH) in zooplankton from June (1.18, 95% CI: 1.06-1.29 
      ng/g lipid weight) to August (1.57, 95% CI: 1.44-1.71 ng/g lipid weight), 
      alongside a higher percentage of alpha-HCH enantiomeric fractions closer to racemic 
      ranges, indicate that glacial meltwater is a secondary source of alpha-HCH to fjord 
      zooplankton in late summer. Except for alpha-HCH, terrestrial inputs were generally 
      associated with reduced POP concentrations in zooplankton, suggesting that 
      increased glacial melt is not likely to significantly increase exposure of legacy 
      POPs in coastal fauna.
