Mitotic Epithelial Of The Lens Of Rainbow Trout Exposed To Benzene Compounds
Table 1: Changes in the mitotic index and frequency of occurrence of micronuclei in the lens epithelium of rainbow trout under the influence of various concentrations of trichlorobenzone on 21 days of the experiment (data in ‰). Results with a significant difference in the mean values compared to the control according to the criterion are highlighted in bold Student's score (P≤0.01)
