Micronucleus cytome assay in the differential assessment of cytotoxicity and genotoxicity of cadmium and lead in <i>Amietophrynus regularis</i>.

The frequency of MN induced in bone marrow erythrocytes of Cd exposed toads was highly significant ( p <0.0001; r=0.69) with 1.93, 2.31, 4.63, 6.16 and 9.00 folds (corresponding to 5, 10, 25, 50 and 75 % of Cd concentrations respectively) increase than the negative control (Figure 2 (Fig. 2) ).
