摘要
为全面履行斯德哥尔摩"控制持久性有机污染物"国际公约,通过对有机氯农药(OCPs)报道的研究,深入分析我国部分水体及沉积物中有机氯农药的污染状况,并与国外其他河流、港湾污染水平对比,作了较为全面系统的总结.结果表明:我国水体及沉积物中OCPs检出率较高,大部分水体及沉积物已经受到不同程度的OCPs污染;有些水体OCPs污染较严重,存在极大的生态风险;沉积物是OCPs富集程度较高的场所,正成为新的OCPs污染源;提出了今后防治工作的重点.
In order to fulfill the Stockholm international treaty on controlling persistent organic pollutants, through analyzing a great number of reports on the contamination of Organochlorine Pesticides （ OCPs）, a profound research on contaminative situation of the OCPs from the regional water and sediment in China is made in this paper. An overall summary is made on this contamination by comparing with the polluted level of rivers or loughs abroad. Results show that China has a higher residual rate of OCPs in water and sediment, most of which are polluted to some extent. Some of the waters are seriously contaminated and can cause great danger to ecology. Sediment has become a new polluting source because of the high residual rate of OCPs. Suggestions on how to prevent such pollution are finally put forward.
