Fig. 2.
Micronuclei (MN) of silver barb exposed to different sublethal concentrations of sumithion. Values with different numeric superscripts differ significantly (p < 0.05) between concentrations within duration in MN. Values with different alphabet superscripts differ significantly (p < 0.05) between duration within concentration in MN. All values expressed as mean ± SD. Photograph in the inset is showing MN (arrow).
