摘　　要：持久性有机污染物(POPs)的高山冷凝效应和全球蒸馏效应,使得青藏高原成为研究POPs的热点区域。系统地综述了青藏高原多介质中多氯联苯(PCBs)、有机氯农药(OCPs)、多环芳烃(PAHs)、溴代阻燃剂(BFRs)和全氟化合物(PFASs)的研究现状和进展,阐述了五类POPs在多介质环境含量赋存特征和环境行为,归纳总结了各类POPs在青藏高原多介质环境的含量分布特征,OCPs:大气>土壤>鱼;BFRs:土壤>鱼>青稞;PCBs:青稞>油菜>土壤;PAHs:冷杉>土壤>水/沉积物>冰川;PFASs:地表水>降雪>土壤。为研究POPs来源、赋存特征和污染研究提供可行性参考,为加强青藏高原新型POPs研究、开发处理技术和完善监测体系提供科学依据。The mechanism of mountain cold-trapping and global distillation effect of persistent organic pollutants(POPs)make the Qinghai-Tibet Plateau a hot research area of POPs.The research status and progress of polychlorinated biphenyls(PCBs),organochlorine pesticides(OCPs),polycyclic aromatic hydrocarbons(PAHs),brominated flame retardants(BFRs)and perfluorinated substances(PFASs)in the multi-media of Qinghai-Tibet Plateau were systematically reviewed.The content occurrence characteristics and environmental behavior of five types of POPs in multi-medium environment were elaborated.The content distribution characteristics of various POPs in the multi-media environment of Qinghai-Tibet Plateau were summarized,OCPs:atmosphere>soil>fish;BFRs:soil>fish>highland barley;PCBs:highland barley>rape>soil;PAHs:fir>soil>water/sediment>glacier;PFASs:surface water>snowfall>soil.To provide a feasible reference for the study of POPs source,occurrence characteristics and pollution research,and to provide a scientific basis for strengthening the research of new POPs on the Qinghai-Tibet Plateau,development of treatment technologies and improving the monitoring system.
