自70年代初期,各国陆续禁用六六六、滴滴涕以来,有机氯农药的残毒及污染,便成为各国十分注意的问题,并相继禁用了一些其他的有机氯农药。滴滴涕已在许多国家禁止使用,但在卫生方面,尤其是在非洲防治疟蚊方面,仍在使用。1974年,美国由于在西北部林区的一些林业害虫及豌豆象虫无药可治,美国环保局批准,在这两个方面允许使用,这一作法,受到某些厂家及用户的拥护,同时受到环保工作者的批评。美环保局认为滴滴涕的使用对人的健康是有害的,但如此放宽使用,是不得已而为之。
Since the early 1970s, countries such as BHC and DDT have successively banned the residues and pollution of organochlorine pesticides, which have become a great concern to all countries and some other organochlorine pesticides have been banned one after another. DDT has been banned in many countries, but it is still being used in health, especially in Africa in the fight against mosquito. In 1974, the U.S. approval of some forest pests and pea insects in Northwest Forests and its approval by the United States Environmental Protection Agency allowed the use of these two aspects. This practice was supported by some manufacturers and users, meanwhile Criticized by environmentalists. The EPA considers that the use of DDT is harmful to human health, but relaxation of it is a last resort.
