SD: standard deviation; −S9: absence of metabolic activation; +S9: presence of metabolic activation; MI: mutagenicity index; Difference of negative control, one-way ANOVA followed by Tukey’s post hoc test (). Each sample was assayed until a cytotoxic response (survival < 70%); positive controls without S9: 4-NQO (1.0 μg/pl.) for TA97, 286 ± 17 revertants, TA98 120 ± 10 revertants, and TA1535 746 ± 58 revertants; AS (1.0 μg/pl.) for TA100, 607 ± 56 revertants; MMC (0.5 μg/pl.) for TA102; with S9: 2AA (1.0 μg/pl.) for TA97, 587 ± 11 revertants for TA98, 305 ± 1 revertants and for TA100, 1436 ± 40 revertants; B[a]P (50 μg/pl.) for TA102, 1448 ± 79 revertants and for TA1535 111 ± 10 revertants. |
