AB  - High mountain cold-trapping effects can play important roles in the global 
      long-range transport of persistent organic pollutants (POPs). Short chain 
      chlorinated paraffins (SCCPs) have recently been included into the Stockholm 
      Convention as a new class of POPs. However, the long-range transport behavior and 
      environmental fate of SCCPs still remain largely unknown in high-altitude 
      mountain areas. In this study, a total of 51 fish samples were collected from 
      five high-altitude mountain lakes and Lasha river across the Tibetan Plateau. 
      SCCPs were positively detected in all fish samples, and the concentrations ranged 
      from 3.9 to 107 ng g(-1) dry weight (dw) with an average of 26.6 ng g(-1) dw. 
      Compared to aquatic organisms from the Artic and Antarctica, the SCCP levels 
      found in alpine fish from the Tibetan Plateau were lower. A significant 
      increasing trend in accumulation levels of SCCPs in alpine fish with the 
      increasing altitude was found on the Tibetan Plateau (r = 0.98, p < 0.001). 
      Shorter chain congener group C10 showed a significant increase in percentage 
      contribution to total SCCPs with increasing altitude, but a contrary tendency was 
      found for longer chain congener group C13. The widespread occurrence of SCCPs in 
      Tibetan fish was mainly sourced from the long-range atmospheric transport, and 
      the altitude-dependent distribution of SCCPs was due to the mountain 
      cold-trapping effects and potential susceptibility to bioaccumulation. To our 
      knowledge, this is the first report regarding the altitude-dependent accumulation 
      of SCCPs in biota in the polar environment.
