除草剂克芜踪对泥鳅红细胞核异常的诱导效应

Induction of Abnormal Nucleus of Erythrocytes of Rana Nigronaculata by Herbicide-Paraguat

采用除草剂克芜踪对泥鳅进行染毒试验,研究其以不同浓度在不同时间范围内对泥鳅红细胞核异常的诱导 效应。实验结果表明:核异常现象与除草剂浓度的相关性有一定的范围;随着时间的推移,泥鳅红细胞核异常率呈 现先上升后下降的规律性变化。从整个实验结果看,施用量极大的克芜踪对水体的污染性不容忽视。

This thesis has mutated micronucleus and nuclear anomalies of erythrocyte from Misgurnus anguilli-caudatus by exploring them in Paraguat. The results were reported as follows: There was a range between rates of nuclear anomalies and concentration of herbicide. The rates of nuclear anomalies varied regularly as time went on, that is to say, it ascended first and then descended. The conclution that the pollution of Paraguat to water shouldn't be ignored could be reached from the results.
