六六六在50年代初作为杀虫剂用于农业和卫生,迄今约有四十年厂史。在我国使用的农药中,约60%为有机氯农药(主要为六六六),其使用量最大,使用面最广,在农业上起到了很大作用。但由于其理化性质稳定,不易在环境和生物体内降解,且由于其趋脂特性,容易在生物体脂肪和脏器内蓄积,并且在动物试验中有致癌的结果,存在着潜在的危害性,因而许多国家对有机氯农药有不同程度和范围的限用或禁用,主要有DDT、六六六、艾氏剂和狄氏剂等。可是至今仍由于缺乏充分的证据,因而争论仍在继续中。
666 was used as a pesticide in agriculture and sanitation in the early 1950s and has a history of about 40 years. About 60% of the pesticides used in our country are organochlorine pesticides (mainly 666). They are the most widely used and widely used ones and have played a significant role in agriculture. However, due to its stable physical and chemical properties, not easily degraded in the environment and living organisms, and because of its fat-like properties, easy to accumulate in body fat and organs, and in animal tests have carcinogenic consequences, there is a potential hazard, As a result, many countries restrict or restrict the use of organochlorine pesticides to varying degrees and ranges, mainly including DDT, BHC, Aldrin and Dieldrin. However, due to the lack of sufficient evidence so far, the debate continues.
