摘要
利用Ames试验对北京第九水厂 7个水处理工艺流程出水有机浓集物的致突变性进行了研究 .于 1998年 6~ 7月间采样 ,经XAD型树脂浓集后用于Ames试验 (TA98和TA10 0菌株加和不加S9体外代谢活化系统 ) .试验结果表明 ,源水加氯后比源水致突变性增强 ,其中加氯源水和机加池出水致突变性最强 ;经活性炭吸附后水样致突变性明显降低 ;
The organic extracts from drinking water in 7 technological processes of Beijing Ninth Water Factory were studied in order to investigate their potential mutagenic activity. Water samples were collected from June to July in 1998, concentrated with XAD\|2、4、7mixed filled colunm and tested with the Ames test (TA98 and TA100 strain with and without S9 addition). The results of the test show that the chloronated source water is more mutagenic than source water. The water samples filtrated by carbon are less mutagenic than the unfiltrated ones. The chloronated source water and flocculation water are the most mutagenic, and the tap water is the least mutagenic among seven processes.
