Abstract:
Objective To evaluate the mutagenicity of mercury, cadmium, arsenic, chromium(Ⅵ)and lead in water on Vicia faba root tip cells. Methods The micronucleus assay of Vicia faba root tip cells were conducted to determine micronucleus rate of Vicia faba root tip cells induced by mercury (0.000 5-1.0 mg/L), cadmium (0.005-1.0 mg/L), arsenic(0.05-2.0 mg/L), chromium (Ⅵ) (0.05-2.0 mg/L) and lead (0.05-3.0 mg/L ) ,and pollution indexes were calculated. Results When the concentration of mercury was ≥ 0.5 mg/L, cadmium ≥ 0.1 mg/L, arsenic ≥ 0.5 mg/L and chromium(Ⅵ)≥ 2.0 mg/L in the water, the micronucleus rate were significantly higher compared with the negative control group, respectively(P
