摘要
本文通过生产性试验，探讨了氯化消毒过程对水中有机物及水的致突变活性的影响规律．结果表明，氯化消毒致使自来水中的次生有机物种类和浓度明显增加，水中除了产生卤代有机物外，还生成了多种其它有机物，如酮、酯等类有机物．氯化消毒后水的致突变活性也有显著的增加，水中产生的主要是直接移码与碱基置换型致突变物质．
A full-scale study was conducted in a water treatment plant to evaluate the effect of chlorine- disinfection on the mutagenicity of organics in water and drinking water. It was found that chlorine- disinfection greatly increased the number and the concentration of low molecular weight organics, not only the halogenated organics, but also some other organics, such as those containing carbonyl groups. The results of Ames test indicated that chlorine - disinfection principally produce some direct -acting mutagens.
