The Study on the Water Pollution of Yi River in Yishui City via the Technique of Micronuclei in Vicia faba Root Tip Test

Abstract:

Yi River is the second longest river in Shandong Province and the largest river in the Yimeng mountain area. The quality of the water has been improved due to the measure taken by the local government. In this study, five water samples of random sites along Yi River in Yishui City were monitored by using the micronuclei in Vicia faba root tip test technique (VNMs). The results showed that the micronuclei frequencies (MCN‰) of all the five samples were approximately equivalent to the control sample. In addition, five samples, respectively 1m, 2m, 3m, 5m and 20m from an illegal sewage outlet along the flow direction, were taken for VNMs. The MCN‰ dates were 17.982‰, 13.261‰, 10.346‰, 4.074‰, 2.475‰, which indicated that the pollution was severe near the sewage outlet while at the distance of 20m from the sewage outlet the water turned good quality. Our study can give a data support for the policy of local government.
