摘要
多氯联苯是最具代表性的环境持久性有机污染物,它具有结构稳定、毒性大、残留性和富集性高、不易降解等特点。在对多氯联苯的分子结构分析的基础上,介绍了其性质和对环境的污染状况,着重讨论了处理多氯联苯的方法,探讨了解决持久性有机污染物的发展方向。
As a typical kind of persistent organic pollutants (POPs), poly chlorinated biphenyls (PCBs) are a class of chlorinated hydrocarbon compounds with high chemical stabilities and toxicity, and are extant in environment and bio-accumulated in food chains. On the basis of analysis and study on PCBs' structure, specifications and determination, a literature survey on environmental pollution caused by PCBs and its prevention and control was conducted with the aim to find an ever efficient and practical approach to completely elimination of PCBs from environment.
