多氯联苯（PCBs）污染现状分析

摘要

文章分别从水体、大气和土壤三个层次阐述了我国环境介质中氯联苯（PCBs）的污染水平,对PCBs的来源、污染途径及控制方法等进行了总结,结果表明,我国环境介质中PCBs污染暂时处于轻度污染,但随着经济发展呈加重趋势,应加强对PCBs污染调查和控制研究,并提出PCBs污染控制对策。%In the paper,concentrations of PCBs in environments media such as water,air,soil were described.The result shows that PCBs pollution in Chinese environmental media is in the range of light pollution,but the potential contamination of PCBs is large.The situation is not optimistic and there is much to be desired.The investigation of PCBs pollution should be strengthened in the future.
