^{
a}Treatments were added at concentrations of MNNG 0.5 g/mL, TPA 0.1 g/mL, and metal mixture (As 2 M, Cd 2 M, and Pb 5 M); ^{b}percentage with respect to controls; ^{c}two experiments with three biological replicates; ^{d}transforming potential (TP) calculated as nmber of transformed foci type III per dish/surviving cells at corresponding sampling day. Statistical analysis, Student’s t-test value *< 0.05, **< 0.01 and ***< 0.001. |
