MCN Efects of the Heavy Metal ions Pb and H on the Viciafaba Root Cell

Micronucleus effects of the heavy metal ions Pb and Hg on Viciafaba root cells were investigated with different eoncentrations of lead acetate and mercuric chloride.The results showed that within certain range of concentrations, both Pb2+ and Hg2+ can induce high mieronucleus frequency (MCNF)of Vicia faba root cells with a dose dependent manner,however,MCNF was found not to increase in a linear pattern with high Pb2+ and Hg2+ concentration.So Vieia ba could be used as the material for fast detection of the genotoxicity of Pb2+ and Hg2+ in enviroment.
