^aThe raw p-values were subjected to multiple testing correction using FDR-adjusted p-value; Statistically significant difference among groups at p <0.05 by One-way ANOVA are highlighted in bold
Values are expressed as mean ± SE (b) and Median (minimum - maximum) (c)
^{*, **, ***} Statistically significant difference from corresponding low- exposed group at p < 0.05, < 0.01 and < 0.001, respectively by Mann-Whitney U test
^## Statistically significant difference from corresponding medium-exposed group at p< 0.01 by Mann-Whitney U test
^d Olive tail moment is the product of the tail length and the fraction of total DNA in the tail.
