通过饮用水氯仿含量与诱变性关系的分析发现,虽然饮用水中氯仿的浓度低于国家卫生标准。但仍可间接反映饮用水有机浓缩物的诱变强度。饮水中氯仿含量与水中石油、游离余氯呈负相关,与锌呈正相关。游离余氯和锌对氯仿形成的影响,可能比石油大。氯仿与石油、游离余氯和锌三者的含量有中等程度的相关关系。 Through the analysis of the relationship between the chloroform content of drinking water and mutagenicity, it is found that although the concentration of chloroform in drinking water is lower than the national health standard. But still indirectly reflect the mutagenic strength of drinking water organic concentrates. The content of chloroform in drinking water was negatively correlated with petroleum and free residual chlorine, but positively correlated with zinc. Free residual chlorine and zinc on the formation of chloroform may be larger than the oil. Chloroform and oil, free residual chlorine and zinc content of the three have a moderate correlation.
