| 摘 要： | 用Ａｍｅｓ试验方法对上海市自来水及黄浦江各支流有机致突变性的动态研究结果表明，该市饮水中有机浓集物的水样比活性平均为１６２Ｒｅｖ／Ｌ（就ＴＡ９８菌株而言）。黄浦江四大支流致突变活性占自来水总活性的７４％，是该市饮水致突变活性的主要来源。特别是四支流之一的虹口港水，其流量比活性约占各支流总活性的１／３，但１９９２～１９９４年间呈逐年下降趋势。本文还分析了富氧、腐植酸等因素对虹口港支流致突变活性的影响。

| Abstract: | From 1991 to 1994,we studied the mutagenicity of drinking water in Shanghai by seasons by Ames test.The results indicated that the mean value of mutagenic activity of organic concentration on TA 98 is 162 revertants per liter.Studies on the four branch ports of Huangpu river showed that they contributed 74% of the total mutagenicity,which accounted for the predominant fraction of the mutagenic activity of Shanghai drinking water.The mutagenicity of Hongkou branch was the highest ,accounting for 1/3 of the total mutagenic activity of the 4 branches.Studies showed that the mutagenic activity of organic concentration of Hongkou branch water was declining year by year,and factors affecting the mutagenic activity were analysed. |
