八氯二丙醚的研究现状与展望

Current situation and prospect of octachlorodipropyl ether

八氯二丙醚是一种农药增效剂,多用于农药喷雾剂、蚊香等。八氯二丙醚在环境中滞留时间长,属于类持久性有机污染物,可能具有致畸、致癌、致突变作用。近10年来国内外学者对环境中的八氯二丙醚进行了比较多的调查和研究。首先对八氯二丙醚的性质、应用情况进行了阐述,然后分析八氯二丙醚的研究现状及可能来源,最后对未来八氯二丙醚的研究的重点和发展趋势进行了展望。文献分析表明:(1)目前国内外的研究集中报道八氯二丙醚在环境中的含量(如农药、蚊香、茶叶、大米、蔬菜、水果等),缺乏八氯二丙醚的环境行为及其在环境中的迁移、转化及降解机理的研究,更缺乏农产品中八氯二丙醚残留的快速检测研究。(2)报道八氯二丙醚对动物及昆虫的毒性及毒理学试验、杀虫活性研究,缺乏八氯二丙醚对人体暴露风险的研究。

Octachlorodipropyl ether is a pesticide synergist,and it is used in pesticide sprays,mosquito coils and so on.Octachlorodipropyl ether has long residence time in the environment and is belonged to persistent organic pollutants.Octachlorodipropyl ether may have teratogenic,carcinogenic,mutagenic effect.A lot of surveys and studies on octachlorodipropyl ether at home and abroad were carried out during the past decade.This paper firstly sums up the character and application of octachlorodipropyl ethers.Then we analyze current situation and possible source of octachlorodipropyl ethers.Lastly we probe the research prospect of octachlorodipropyl ethers.The literature shows：（1） Large number of surveys and studies have focused on the occurrence and levels of octachlorodipropyl ether in environment（eg.pesticide,mosquito coils,tea,rice,vegetable,fruit,etc.）,but very few study has focused on the environmental behavior of octachlorodipropyl ether and the mechanism of octachlorodipropyl ether on migration,transformation,degradation;the rapid residual detection way of octachlorodipropyl ether in agricultural products.（2） Some studies have been conducted to investigate the toxicity of octachlorodipropyl ethers and its insecticidal activity of animals and insects.However,few literature was about the risk exposure of octachlorodipropyl ether on human.
