蚕豆根尖微核技术监测剑江都匀市区河段水质

On Applying the Micronucleus Technology of the Root Point of Broad Beans to Monitor the Water Quality in Duvun Rivers

本文利用蚕豆根尖微核技术监测剑江都匀市区河段水质的污染状况,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检测,结果表明,各断面水样均能引起微核率升高,桃溪园、枣园、水厂、彩虹桥、百子桥和文峰园断面的微核千分率分别为6.92‰、6.00‰、9.53‰、11.36‰、6.63‰、5.57‰,PI分别为2.06、1.79、2.83、3.38、1.97、1.66。按照污染指数划分标准,枣园、百子桥和文峰园断面的水质为轻度污染,桃溪园、水厂、彩虹桥断面水质为中度污染。

In this paper, the micronucleus of the root point of brand beans is applied to monitor the pollution situation of water quality in Duyun rivers. On the basis of a mensuration of the MCN%0 and PI of the cell in the root point of brand beans in six water sections and detection of F, the results show that water sample in each water section can cause the rise of MCN%0. The MCN%0 of the water section in Taoxiyuan, Zaoyuan, Water Factory, Rainbow Bridge, Baizi Bridge and Wenfengyuan section are as follows： 6.92 %0, 6.00 %0, 9.53 %0, 11.36 %0, 6.63 %0, 5.57 %0; PI are as follows： 2.06, 1.79, 2.83, 3.38, 1.97, 1.66. According to the PI standards, the water in Zaoyuan, Baizi Bridge and Wen- fengyuan sections is slightly polluted; that in Taoxiyuan, Water Factory and Rainbow Bridge sections is polluted moderately.
