南湖位于湖北省武汉市洪山区,是武汉市仅次于东湖的第二大湖。多年来,受周边污水直排入湖的影响,南湖污染越来越严重,目前水质已降为劣5 类,远远就能闻到阵阵恶臭。运用蚕豆根尖细胞微核试验技术对华农南湖排污水的遗传毒性进行了研究,为评价华农南湖排污水的污染情况提供了理论依据。结果显示:水样的污染指数明显高于3.5,说明华农南湖排污水受到严重污染;随着暴露时间的增加微核率成二次曲线,先增大后减小,在32h处最大;排污水的浓度与微核率大致呈正相关。研究表明,蚕豆根尖细胞微核是水质毒理检测的有效指标,其细胞有丝分裂后期异常细胞比率也可作为水质毒理检测的观察指标。本文对此次试验进行了较全面地分析讨论。

South Lake is located in Hongshan District of Wuhan City, Hubei Province, Wuhan City is second only to the Great Lakes East Lake. Over the years, by surrounding the impact of sewage straight into the lake, South Lake pollution has become increasingly serious, the current poor water quality has been reduced to 5 classes, much can smell the stench blowing. Faba root tip cells using micronucleus test technology to China agricultural South Lake sewage water genotoxicity was studied for the evaluation of Chinese agricultural water pollution in South Lake sewage provides a theoretical basis. The results showed that: water pollution index was significantly higher than 3.5, indicating Chinese agricultural South Lake sewage water is seriously contaminated; as exposure time increases micronucleus into a quadratic curve, then decreased at 32h to be the highest; sewage water The concentration of micronuclei generally correlated. Studies have shown that root tip cell micronucleus test is an effective water quality indicators of toxicity, its late mitosis ratio of abnormal cells can be used as indicators of water quality observations of toxicological testing. This article on the trials of a more comprehensive analysis and discussion.

The results showed that: water pollution index was significantly higher than 3.5, indicating Chinese agricultural South Lake sewage water is seriously contaminated; as exposure time increases micronucleus into a quadratic curve, then decreased at 32h to be the highest; sewage water micronucleus rate of the concentration of roughly correlated. Studies have shown that root tip cell micronucleus test is an effective water quality indicators of toxicity, its late mitosis ratio of abnormal cells can be used as indicators of water quality observations of toxicological testing. In this paper, the test for a more comprehensive analysis and discussion.
