概述了中国及国际社会对持久性有机污染物(PersistentOrganicPollutants,POPs)的关注情况。并通过对POPs农药在珠江三角洲地区(PearlRiverDeltaArea,PRD)使用情况的调查,以及对珠江三角洲地区POPs农药在各环境介质中的污染现状的文献综述,结合环境污染数据以及POPs农药污染调查工作中得到的数据和信息,对该地区POPs污染的可能原因和环境中可能存在的新近污染源进行了初步探讨。同时也指出了当前珠江三角洲地区在POPs农药削减与淘汰工作中所遭遇到的缺乏完善的管理体系等困难,并针对问题提出了包括加大科研投入,加强基础研究,掌握污染物来源和去向,加强替代药物的研究,建立和实施更严格的环境法规以及标准,加强环境监测能力建设,建立POPs农药污染的信息公开机制等一系列的控制对策。
Outlines the concerns of the Chinese and international communities about Persistent Organic Pollutants (POPs). Through the investigation of the use of POPs pesticides in the Pearl River Delta region (PRD) and the literature review of the pollution status of POPs pesticides in various environmental media in the Pearl River Delta region, combined with environmental pollution data and POPs pollution investigation, Of the data and information on the possible causes of POPs pollution in the region and the environment may have been the recent sources of pollution were discussed. At the same time, it also points out the difficulties in the current Pearl River Delta region such as the lack of a sound management system for the reduction and elimination of POPs pesticides. In addition, it puts forward some suggestions on the issues such as increasing investment in scientific research, strengthening basic research, grasping the sources and destinations of pollutants, A series of control measures such as strengthening the research on alternative medicines, establishing and implementing stricter environmental laws and regulations and standards, strengthening environmental monitoring capacity-building, and establishing a mechanism for disclosing information on pesticide contamination in POPs will be strengthened.
