AB  - Long-range atmospheric transport (LRAT) plays a crucial role in the occurrence of 
      persistent organic pollutants (POPs) in remote regions. When studying the LRAT of 
      POPs on the Tibetan Plateau, westerly-controlled regions have received 
      insufficient attention compared with regions influenced by the Indian monsoon or 
      air flow from East Asia. We investigated the residual levels of POPs in soils 
      from the eastern Pamirs and used air backward trajectory analysis to elucidate 
      the influence of potential source regions via LRAT. Organochlorine pesticides 
      (OCPs, mainly comprising DDTs, HCHs, and HCB), polychlorinated biphenyls (PCBs, 
      mainly comprising penta- and hexa-CBs), and polycyclic aromatic hydrocarbons 
      (PAHs, mainly comprising three- and four-ring) were detected at low 
      concentrations of 40-1000, <MDL-88, and 2100-34,000 pg/g, respectively. We 
      elucidated three major geographical distribution patterns of POPs, which were 
      influenced by (1) the distribution of total organic carbon and black carbon in 
      soil, (2) historical use of pesticides in the Tarim Basin, and (3) continuous 
      emissions. Central Asia and the Tarim Basin were major potential source regions 
      of POPs reaching the eastern Pamirs via LRAT. Historical use of technical HCH or 
      lindane and technical DDT in potential source regions may contribute to the 
      accumulation of HCHs and DDTs in the eastern Pamirs, respectively. Local sources 
      seem to play a more important role in the occurrence of PAHs in the study area. 
      By being under the control of less contaminated westerly air flow, the eastern 
      Pamirs are more pristine than the core of the Tibetan Plateau where the Indian 
      and East Asia monsoons deliver contaminants from highly industrialized areas in 
      East China and India.
