摘 要:多环芳烃(PAHs)是一类持久性有机污染物(POPs),普遍存在于环境介质中,其主要来自有机物的不完全燃烧或高温处理以及石油泄漏。PAHs进入大气后通过沉降和雨洗等途径进入地表和地下,在土壤和地下河沉积物中富集,因其难以转化,岩溶地下空间可能成为其最终归宿,成为潜在污染源,危害岩溶生态和人类健康。针对岩溶区的特殊性和脆弱性,综述了国内外对岩溶区PAHs的研究状况,并分析了中国岩溶区PAHs的污染水平,以期让中国岩溶区已遭受有机污染的事实引起关注和重视。Polycyclic aromatic hydrocarbons(PAHs)were a class of persistent organic pollutants(POPs),generally existing in the environment medium,which were mainly caused by the incomplete combustion of organic materials or high temperature treatment and oil spill.After PAHs got into the atmosphere,they would get into the surface and underground through the deposition and rain washing,enriching in soils and ground river sediments.Because PAHs were difficult to convert,the underground space may be the ultimate destination of PAHs and consequently be the potential source of pollution,harming karst ecosystem and human health.In view of the particularity and vulnerability in karst areas,this paper summarizes the research of PAHs in karst regions and analyzed the pollution level of PAHs in China in order to arouse attention and recognition that the karst areas in our country had suffered from organic pollution.
