TI  - Legacy and Emerging Persistent Organic Pollutants (POPs) in Terrestrial 
      Compartments in the High Arctic: Sorption and Secondary Sources.

AB  - Legacy persistent organic pollutants (POPs) such as polychlorinated biphenyls 
      (PCBs), organochlorine pesticides (OCPs), and emerging perfluoroalkyl substances 
      (PFASs) were measured in vegetation and soil samples collected at remote lakes in 
      the Canadian High Arctic. Field studies were carried out in 2015 and 2016 to 
      assess concentrations of POPs, study the relevant sorbing phases, and determine 
      whether Arctic soils were sinks or sources of legacy POPs to the atmosphere and 
      to neighboring lakes. The patterns of legacy POPs in vegetation and soils were 
      dominated by low molecular weight PCB congeners along with OCPs, confirming the 
      importance of long-range atmospheric transport. Lipid and non-lipid organic 
      matter was a key determinant of legacy POPs in Arctic vegetation. Soil organic 
      matter was the main descriptor of hydrophobic PCBs and OCPs in soils, while soil 
      inorganic carbon content, was an important driver of the sorption of PFASs in 
      soils. While contaminant concentrations were low in soil and vegetation, higher 
      PCBs and PFOS organic and inorganic carbon-normalized concentrations were found 
      at Resolute Lake indicating the presence of local sources of contamination. 
      Comparison of fugacities of PCBs in soil and air from Resolute Lake indicated 
      soils as net sources of PCBs to the atmosphere.
