国外,尤其美国,在饮水中有机物的分离鉴定,饮水中有机浓集物致突变性鉴定以及饮水污染与人类癌症关系方面做了许多工作,但是我国尚未见有关饮水中有机物致癌、致突变可能性的报道.为了在饮水中有机物的浓集方法和致突变鉴定方面进行探讨,我们选择有机物污染较严重并以地面水为主要供水源的某市自来水厂,于1981年8月初分别在所属A厂和B厂浓集出厂水样, Abroad, especially in the United States, has done a lot of work in the separation and identification of organic matter in drinking water, the identification of the mutagenicity of organic concentration in drinking water, and the relationship between drinking water contamination and human cancer, but there is no possibility of carcinogenicity and mutagenicity of organic matters in drinking water in China. In order to discuss the method of concentrating organic matter and identification of mutagenicity in drinking water, we selected a city water plant with serious organic pollution and ground water as the main water supply source. They were planted in the A plant in early August 1981. And factory B concentrates the factory water sample,
