AB  - In the background region of the Tibetan Plateau (TP), the rapid urbanization 
      probably results in the massive generation of persistent organic pollutants 
      (POPs), which lacks monitoring and evaluation. Since landfill could serve as an 
      important sink of the locally used POPs, the analysis of POPs in the Tibetan 
      landfill area might help us to understand the source composition and their 
      transport in the TP. In this study, the concentration variations of 
      polybrominated diphenyl ethers (PBDEs) in five soil profiles and seven surficial 
      sediments around the largest Tibetan landfill were investigated. The total 
      concentrations of PBDEs ranged from 128 to 1219 ng/kg in soils, and from 447 to 
      7295 ng/kg in sediments. The dominance of nona- and deca-BDEs possibly indicated 
      the wide usage of deca-BDE as flame retardant in the TP. The vertical and spatial 
      distribution patterns of PBDEs within soils plausibly revealed their main 
      transport pathways by atmospheric dispersion and leachate seepage from landfill. 
      Based on principal components analysis and multiple linear regression, these two 
      pathways were estimated to account for 61% and 39% of the total concentrations, 
      respectively. Additionally, the spatial and vertical distributions of octa-to 
      deca-BDEs within soils were significantly influenced by soil particle size. 
      Although the PBDEs inventory in the study area was comparatively low, the rapid 
      urbanization in the TP might dramatically accelerate the PBDE emissions in the 
      future. This study firstly introduced the presence of local PBDEs in the TP, and 
      the inventory already influenced the surrounding environment. Once involved in 
      the regional cycle of the TP, the local source of PBDEs from waste might 
      significantly serve to raise background level resulting otherwise primarily from 
      long-range atmospheric transport.
