用Ames试验、明亮发光菌发光抑制试验对2种水源的原水、出厂水及出厂水经再次过滤后的水(过滤水)进行致突变性和急性毒性分析.用GC/MS技术分析水中有机污染物的种类和数量.结果表明:长江原水、出厂水、过滤水的致突变性(平均RM值)分别为3.26,1.57,0.78,呈逐渐下降趋势;湖水则分别为0.97,2.10,0.97,呈“Λ”型.急性毒性(发光菌发光率)长江水分别为64.38%、87.76%和97.21%;湖水则分别为84.08%、1.57%和90.49%.GC/MS分析表明,长江水中有机物种类数分别为12,12,10,湖水则分别为21,27,15,分析结果与致突变性和急性毒性实验基本一致.
The mutagenicity and acute toxicity of the raw water, the ex-factory water and the ex-factory water of the two water sources were tested by the Ames test and the luminescent inhibition test of the luminous luminescent bacteria through the filtered water (filtered water). The organic pollutants in the water were analyzed by GC / MS The results showed that the mutagenicity (average RM value) of the raw water, produced water and filtered water in the Yangtze River was 3.26, 1.57 and 0.78, respectively, showing a gradual downward trend while that in the lake waters was 0.97, 2.10 and 0.97, respectively “Λ” .Acute toxicity (luminescent rate of luminescent bacteria) was 64.38%, 87.76% and 97.21% respectively in the Yangtze River and 84.08%, 1.57% and 90.49% in the lake respectively.GC / MS analysis showed that the number of organic matter Respectively 12,12,10 and 21,27,15 respectively. The results of the analysis are consistent with those of mutagenicity and acute toxicity.
