摘要:
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.
Abstract:
Tests are conducted on the mutagenicity and acute toxicity of raw water sample, tap water sample, and filtered water sample from two sources by means of Ames test and luminescent bacterium bioassay. The types and number of organic pollutants in the water samples are analyzed by GC-MS(gas chromatography mass spectrograph). The results of the analysis show that for mutagenicity the average mutation rate of raw water sample, tap water sample and filtered water sample from Yangtze River are 3.26, 1.57, and 0.78 respectively, showing a declining tendency; for the three water samples from the lake are 0.97, 2.10, and 0.97 respectively, showing a “Λ” tendency. For acute toxicity, the rates of luminosity of the three water samples from the Yangtze River are 64.38%,87.76%,and 97.21% respectively, and for the three water samples from the lake are 84.08%,1.57% and 90.49% respectively. The results from GC/MS analysis indicate that for the three water samples from the Yangtze River, the number of types of organic extracts are 12, 12 and 10 respectively, and for the water samples from the lake are 21, 27 and 15 respectively. The results of the analysis are in accordance with the results of the tests on mutagenicity and acute toxicity.
