蚕豆根尖细胞微核技术监测南太湖水质污染状况的研究

目的]为综合评价水质状况和保护人体健康提供参考，同时为建立太湖生态监测机制提供基础资料。方法]利用蚕豆根尖细胞微核技术对湖州市太湖南岸的水质进行了检测，测定相同采样点不同月份的水样微核千分率（MCN）、污染指数（PI）及主要化学指标，并进行统计分析。结果]经南太湖水处理的蚕豆根尖细胞出现微核和染色体畸变，可观察到单微核、双微核、三微核、分裂后期染色体桥和染色体断片。太湖水质污染比较严重，各月份MCN和对照组相比差异极显著（P〈0．01），5月份湖水污染最为严重，其PI值达到4．08。太湖水质主要污染物为氮、磷等营养盐和耗氧有机物。结论]对被污染水体的治理提出了有价值的建议。为治理太湖污染提供了科学借鉴。

Research on the Water Quality-monitoring of the Southern Taihu Lake with Micronucleus Technique of Vicia faba Root Tip Cell

Objective] The reference for the integrated evaluation of water quality and the protection of human health and the basic data in the establishment of the mechanism of ecological monitor in Taihu Lake were provided.Method] The water quality of the southern Taihu Lake was monitored with the micronucleus technique of Vicia faba root tip cell and the main chemic indexes such as MCN and PI in the samples at fixed place in different months were determined and statistically analyzed.Results] The micronucleus an...
