TI  - Polychlorinated Naphthalene Congener Profiles in Common Vegetation on the Tibetan 
      Plateau as Biomonitors of Their Sources and Transportation.

AB  - Polychlorinated naphthalenes (PCNs) are globally transported, carcinogenic, 
      persistent organic pollutants (POPs) that were recently added to the Stockholm 
      Convention with 184 parties. The Tibetan Plateau plays an important role in the 
      global transportation and distribution of POPs. Knowledge of PCN sources and 
      transportation on the Tibetan Plateau is important for their control globally. In 
      this study, we quantified the congener-specific concentrations of PCNs in lichen, 
      moss, soil, and air samples collected on the Tibetan plateau and found that 
      common lichens were effective biomonitors for predicting atmospheric PCNs in this 
      area. The physiochemical properties of the PCNs, the temperatures, and the lichen 
      lipid contents were identified as important factors influencing PCN partitioning 
      between lichens and air. Lichen-air partitioning equations were established and 
      used to predict PCN concentrations in air in Southeast Tibet. The lichens could 
      be used as PCN biomonitors to clarify their spatial variations, sources, and 
      transportation in the southeast of the plateau. PCN concentrations in lichens 
      increased with altitude, suggesting that high-mountain cold-trapping influenced 
      the PCN transportation behavior. Principal component analysis and linear 
      discriminant analysis showed that the major source of PCNs in this region was 
      long-range atmospheric transportation via the Indian monsoon in summer and wind 
      from Southwest Asia in winter. This study provides a novel method using PCN 
      congener profiles as fingerprints and statistical models for studying the 
      geochemical effects of conditions in high-mountain regions on the contamination 
      behaviors of 75 congeners of the notorious PCNs.
