对某水厂深度处理前后的水质进行致突变性研究。Ames试验结果表明,水源水及自来水浓缩物都存在直接致突变物,而处理后水浓缩物有机物含量明显降低。微核试验表明:12.5L、25L水源水及自来水浓缩物与对照组相比微核数升高(P<0.05)。2L自来水浓缩物即可诱发SCE频率增高,且随着相当水量的增加,SCE频率增高(P<0.05)。 Study on mutagenicity of water quality before and after deep treatment in a water plant. Ames test results showed that there was a direct mutagen in water and tap water concentrates, while the content of organic matter in water concentrate after treatment was significantly reduced. The micronucleus test showed that the micronuclei of 12.5L, 25L tap water and tap water concentrate increased compared with the control group (P <0.05). 2L tap water concentrate can induce an increase in SCE frequency, and with a corresponding increase in water volume, SCE frequency increased (P <0.05).
