AB  - Previous work documented that forest plays an important role in the deposition of 
      persistent organic pollutants (POPs) in the southeast Tibetan Plateau (TP) due to 
      the "forest filter effect". However, forest types in the southeast TP are 
      entirely different and the influence on POPs fate and forest filter effect by 
      different forests remains unclear. This study focused on the distribution and 
      transfer of organochlorine pesticides (OCPs) in soil of different forest types 
      (quercus, birch, fir, and spruce dominated forests) in Mt. Shergyla, southeast TP 
      under similar environmental and meteorological conditions. Total levels of  summation operatorHCHs, 
       summation operatorDDTs and HCB in soils ranged from < LOD to 2.25 ng/g dry weight (dw), < 
      LOD-10.2 ng/g dw, and < LOD-0.95 ng/g dw, respectively. Concentrations of OCPs in 
      humus layers were significantly higher than those in mineral layers in the four 
      forest types. Relatively higher  summation operatorDDTs concentrations were found in soil profile 
      of broadleaved birch forest, while higher concentrations of  summation operatorHCHs and HCB were 
      found in soil profile of coniferous fir forest, and the same trend was observed 
      in fresh leaf samples. Air-to-ground fluxes and mobility of OCPs in the four 
      forest types were also evaluated. Relatively higher fluxes were found in fir 
      forests than in other forest types, suggesting that fir forest could be more 
      effective to transfer OCPs from the air into soil in the southeast TP. The 
      findings in this study would be helpful for improving model simulation of POPs 
      fate in different forest ecosystem.
