ABSTRACT
Objective To study the mutagenicity of water of man-made lake from Wujiang River in Jinhua. Methods The mutagenicities of water samples collected from 7 representative sampling points in man-made lake in Wujiang River were detected with micronucleus test in vicia faba root tip cells in Oct. 2000 and Oct. 2001 in Jinhua, Zhejiang. Results All water samples showed significantly higher frequencies of micronucleus with a range of 8.06‰～27.79‰ compared with 5.04‰ of negative control (P
ABSTRACT
Objective To study the genetic effects of lead on root tip cell of Vicia faba. Methods Micronucleus tests were conducted on root tip cell of Vicia faba treated with Pb2+ of concentrations of 0.1, 1.0, 5.0, 25.0, 50.0 mg/L for 12-36 h. Results The results indicated that the rates of micronucleus of lead-treated tip cell were significantly higher than that of the control (P
