摘要
冰雪是地球生态系统中重要的环境组分,它们不仅直接影响着全球的水循环,而且也直接影响着一些物质在不同纬度和海拔上的分布。随着气候的变化,在中低纬度使用和排放的POPs能够挥发到大气中,并伴随着大气的运动向高纬度高海拔地区迁移,这对生态环境造成了极大的威胁。本文主要介绍了持久性有机污染物的危害、历史排放数据,并详细阐述了国内外研究人员对冰雪中POPs的研究现状。
Snow and ice are important environmental components of the earth ecosystem. They directly affect the global water cycle as well as the distribution of some substances in different latitude and altitude. With the changes of climate, POPs that are used and discharged at mid or low latitude area volatilize in the atmosphere and transfer to high latitude area with atmospheric motions, which greatly threat the ecological environment. In this paper, an overview of the POPs hazard and emissions in history were introduced. And the status quo of researches on the snow and ice home and abroad were reviewed.
