摘要
近年来 ,水体污染日趋严重 ,各国学者从氯化后饮水中分离出多种致突变、致癌物质。为此我们采用Ames试验 ,对珠江流域主要取水点的水源水和对应自来水中的有机致突变物污染情况进行了研究。研究表明 ,部分取水点的有机致突变物污染较严重 ,并且氯化消毒后自来水的致突性大于水源水的致突性。因而 ,加强饮水中致突变物质的检测 ,改进净水消毒剂和净水流程很有必要。
In recently, the pollution in water is more and more serious. Scientists detected some carcinogens in the chlorinated drink water. We detected the mutation of the source water and its chlorinated drink water in the Pearl River by the Ames test. The study shows some samples have high mutation, and the mutation of the chlorinated drink water is higher than that of source water. As a result, it is necessary to study the mutation of drink water and improve the drink water disinfecting and producing technique.
