利用蚕豆根尖微核技术监测韶关市区河段水质的研究

利用蚕豆根尖细胞微核技术监测韶关市区河段水质污染状况,测定6个断面水样的蚕豆根尖细胞微核千分率(MCN‰)及污染指数(PI),并进行F检验。结果表明,各断面水样均能引起微核率升高,孟洲坝、曲江桥、武江桥、高桥、长坝和十里亭断面的微核率分别为10.73‰、7.94‰、5.98‰、5.85‰、5.78‰、4.45‰,PI分别为3.04、2.25、1.69、1.66、1.64、1.26。按照污染指数划分标准,十里亭断面基本没有污染,武江桥、高桥和长坝断面均为轻度污染,孟洲坝和曲江桥断面属于中度污染。表明除十里亭断面外,其余各断面均有不同程度的污染。

The Utilization of Micronucleus Test in Vicia faba Root Tip Cell to Detect the Water Quality of River in Shaoguan City

The micronucleus test in Vicia faba root tip cell was utilized to detect the water quality of River in Shaoguan City.The MCN‰ and PI were determined and the F-test was used to evaluate the statistical difference in Vicia faba MCN‰ among six samples. The results showed that Each of samples can makes the micronucleus frequency go up, The micronucleus frequency in Mengzhouba, Qujiang bridge, Wujiang bridge, Gao bridge, Changba and Shiliting reach 10.73‰, 7.94‰, 5.98‰, 5.85‰, 5.78‰ and 4.45‰, PI reach 3.04, 2.25, 1.69, 1.66, 1.64 and 1.26. According to Divide the standard of PI, the sample in Shiliting was not polluted, the samples in Wujiang bridge, Gao bridge and Changba were polluted lightly, the samples in Mengzhouba and Qujiang bridge were of Medium pollution. This suggests that the water quality of river in Shaoguan city was partly polluted to different degrees except the sample in Shiliting.
