青藏高原持久性有机污染物的研究进展

A Review of the Research on Persistent Organic Pollutants in Tibetan Plateau

由于青藏高原特殊的地理条件,对研究持久性有机污染物(POPs)的迁移与转化等地球化学过程有着独特的意义。平均海拔高于4 000 m,高山冷凝效应在高原上得到集中体现。大面积的人迹罕至的环境,POPs的分布很少受到人为二次影响。高原地区特有的多冰川的存在,完整地记录了POPs的沉降历史。随着近年来对青藏高原POPs的监测和研究工作的开展,研究者逐渐认识到对高原POPs研究的重要性和认识的不足之处。本研究就目前为止对高原地区POPs的研究现状进行综述,着重介绍对青藏高原不同环境介质中POPs的监测及研究成果,同时总结了高原POPs的物质来源与迁移等研究成果,并根据研究现状提出了展望。

Due to the unique geographical conditions, Tibetan Plateau is an ideal place for researchers to study geochemical processes of persistent organic pollutants （ POPs ） in natural environment, such as transportation and transformation. The mechanism of mountain cold-trapping of POPs could be observed in Tibetan Plateau since its average altitude of more than 4,000 m. The distribution of POPs should rarely be secondly destroyed from few human activities. The precipitation history of POPs could be completely recorded in ices due to so many glaciers in plateau. With research about POPs being done in Tibetan plateau, the importance and significance of the work are gradually recognized. This article intends to review these reports about POPs research so far in plat- eau area, and focuses on monitoring results in some environmental media. Also, the research results about source and the transportation of POPs are also summarized in this review. In the end, some prospects for future research about POPs in Tibetan Plateau are also proposed.
