      Tibetan butter.

AB  - The Tibetan plateau is considered a potential cold trap for persistent organic 
      pollutants (POPs) and plays an important role in the global long-range transport 
      of these compounds. This present work surveyed the concentrations of 
      polychlorinated biphenyl (PCBs) and polybrominated diphenyl ethers (PBDEs) in 
      Tibetan butter samples collected from different prefectures in Tibet autonomous 
      region (TAR). summation operator(25)PCB concentrations ranged from 137 to 2518 pg 
      g(-1) with a mean value 519 pg g(-1), which were far lower than those in the 
      butter from other regions in the world. The highest level was found in butter 
      from Sichuan province, which is located to the east of the Tibetan plateau and 
      the lowest value was in samples from southeast TAR. The average concentration of 
      summation Sigma(12)PBDE was 125 pg g(-1). The sample with highest and lowest 
      summation Sigma(12)PBDE concentration (955 and 18.0 pg g(-1)) was from the south 
      and southeast part of the plateau, respectively. Back trajectory model implied 
      that the sources of these two groups of POPs were by atmospheric deposition in 
      south, whereas the western plateau was mainly influenced by the tropical monsoon 
      from south Asia. Air currents from Sichuan and Gansu province are further 
      responsible for the atmospheric transport of PCBs and PBDEs to the eastern and 
      northern side of the plateau. Local air concentrations of summation Sigma(5)PCBs 
      predicted using air-milk transfer factor were at the lower end of published 
      global levels.
