近来有很多资料报道证实了在水的氯消毒过程中能形成含有多种卤族化合物,其中三卤甲烷在致癌方面具有潜在性危害。 本实验的目的是为了获得有关二氯溴甲烷和二溴氯甲烷致癌性慢性生物实验的新资料,以预测在饮用水的氯消毒时形成的这些卤族化合物有无致癌性和解决卫生标准问题。 实验应用苏联医科院《标化》养殖场提供的杂交鼠CBA×C_(57)B_1/6 645只,分为14组,每组50～75只。二氯溴甲烷和二溴氯甲
Recently, there is a lot of data confirming the formation of a variety of halogen compounds in the process of chlorine disinfection of water, in which trihalomethanes are potentially harmful to cancer. The purpose of this experiment was to obtain new information on chronic carcinogenicity trials of dichlorobromomethane and dibromochloromethane to predict the carcinogenicity of these halides formed during the chlorine disinfection of drinking water and to address health standards. The experimental application of the Soviet Union Medical Institute “standardized” farms provided hybrid mice CBA × C_ (57) B_1 / 6 645, divided into 14 groups of 50 to 75 each. Dichlorobromomethane and Dibromochloromethane
