AB  - As persistent organic pollutants (POPs) newly banned by the Stockholm Convention, 
      polychlorinated naphthalenes (PCNs) have been widely detected in various 
      environmental matrices. To date, however, the occurrence of PCNs in soils and 
      plants in the Arctic environment has not been reported. In the current study, the 
      concentrations and distribution of PCNs in Arctic soils and plants from Svalbard 
      were analyzed. Total PCN concentrations ranged from 5.3 to 2550 pg/g dry weight 
      (dw) in soils and 77 to 870 pg/g dw in plants. The higher levels of PCNs near the 
      research stations and Longyearbyen town highlighted the significant influence of 
      local anthropogenic emission sources. The composition of PCNs in Arctic soils and 
      plants was dominated by lower chlorinated homologues, especially mono- to 
      trichlorinated naphthalenes, which accounted for over 80 % of total PCNs in the 
      soil and plant samples. The correlation analysis indicated the potential 
      influences of total organic carbon (TOC) content on PCN concentrations in the 
      soil, and octanol-air partition coefficients (K(OA)) or octanol-water partition 
      coefficients (K(OW)) on PCN accumulation from soils to plants. To the best of our 
      knowledge, this is the first study to report on the concentration and 
      distribution of PCNs in Arctic soils and plants.
