Abstract


We have investigated micronuclei and other nuclear abnormalities in peripheral blood erythrocytes of saddle cichlid, Aequidens tetramerus, in order to evaluate the genotoxic and mutagenic effects of copper sulfate. Specimens (n = 4) were subjected to copper sulfate 7,975 mg.L-1 with an equal control group (n = 4).The Mann-Whitney test was used to compare nuclear abnormality frequencies between control and treatment groups. Results showed statistically significant difference of altered cells amongst the exposed acarás and the control group. Our results emphasize the importance of the micronucleus test in the assessment of genotoxic effects in fish, which can be used as bioindicators of the exposure of human populations to chemicals with a genotoxic potential found in drinking water.
