| 摘 要： | 纯培养富营养化湖泊常见的４种藻类，在不同加氯量、不同代谢产物含量的条件下模拟饮用水氯化消毒工艺。应用Ａｍｅｓ致突变试验检测氯化样品的致突变性，应用气相色谱分析法测定氯化样品的三氯甲烷（ＨＣｌ３）生成量。结果表明：氯化样品的致突变活性与藻类代谢物含量及加氧量均呈正相关（Ｐ＜０．０５）；ＣＨＣｌ３生成量随代谢物含量、加氯量增加而增加，与致突变活性之间无明显相关关系。

| Abstract: | Four common species of algaes from eutrophicated lake were purely cultured in our lab, the algal metabolites were chlorinated at different chemical oxgen demand (COD) and dosage of chlorine by imitating the chlorinating process of drinking water. The mutagenicity and the concentration of trichloromethane of chlorinated samples were determined by Ames test and Gas Chromatography. The results showed that the mutagenic activity of chlorinated samples was positively correlated with the concentration of algal metabolites and chlorine (P<0. 05 ). The concentration of trichloromethane rised with the increase of algal metabolites and chlorine, but it was not correlated with the mutagenic activity. |
