Mitotic Epithelial Of The Lens Of Rainbow Trout Exposed To Benzene Compounds
Table 2: Changes in the mitotic index and frequency of occurrence of micronuclei (Q) in the lens epithelium of rainbow trout under the influence of various concentrations of 2-naphthol on 21 days of the experiment (in ‰). Results with a significant difference in mean values compared to the control according to the Student's criterion (P≤0.01) are highlighted in bold.
