摘要
近年来,岩溶地区不同环境介质中持久性有机污染物(POPs)的研究已经成为国际上该领域的热点问题。本文对POPs在岩溶地区水环境、土壤、大气和生物中的残留状况、分布特征、影响因素、迁移机制和可能来源等方面的研究现状进行了综述,结果显示岩溶地区已普遍检测出POPs,部分地区环境介质中POPs的浓度有显著降低的趋势;同时讨论了目前国内外岩溶地区POPs研究中存在的问题,并提出该研究未来可能的发展趋势。
Recently,researches of persistent organic pollutants （POPs） in different environmental media from karst regions are getting more attention both at home and abroad. In this study,residues, distribution, influencing factors, transport mechanism and possible sources of POPs in the aquatic environment, soil, air and organisms are discussed. The results suggest that POPs have been detected in karst areas and the concentrations of POPs in environmental media from some areas are generally reduced. Furthermore, this paper pointes out that the further work is needed for the study of POPs in different environmental media from karst regions.
