【摘要】 目的了解金华婺江人工湖水的致突变性。方法于2000年10月和2001年10月分别采集金华婺江人工湖有代表性的7个采样点的水样进行蚕豆根尖细胞微核试验。结果各水样微核率 (8.06‰～27.79‰ )均高于阴性对照(5.04‰ ) ,P<0.05或P<0.01 ,2000年至2001年重度污染的采样点由4个上升为5个 ,其余均为中度污染。结论金华婺江人工湖呈中度以上污染更多还原

【Abstract】 Objective To study the mutagenicity of water of man-made lake from Wujiang River in Jinhua. Methods The mutagenicities of water samples collected from 7 representative sampling points in man-made lake in Wujiang River were detected with micronucleus test in vicia faba root tip cells in Oct. 2000 and Oct. 2001 in Jinhua, Zhejiang. Results All water samples showed significantly higher frequencies of micronucleus with a range of 8.06‰～27.79‰ compared with 5.04‰ of negative control (P<0.05 or P<0.01). The number of the water sampling points with heavy pollution increased from 4 in 2000 to 5 in 2001. The other two sampling points showed moderate pollution. Conclusion The water quality of man-made lake in Wujiang River had been in the state of moderate pollution or higher.更多还原
