Estimation of Genotoxic Effect of Insecticide Chromagor at Goldfish (Carassius Auratus) after 5 Days of Treatment

Summary/Abstract: The genotoxic effects of insecticide chromagor (dimethoate) were evaluated in goldfish Carassius auratus using the micronucleus test. The aim of this study is to estimate the damage of DNA, after treatment of goldfish Carassius auratus for five days with insecticide chromagor. The micronucleus assays have been used increasingly to evaluate genotoxicity of many compounds in polluted aquatic ecossystems. In order to investigate the frequencies of micronuclei and to assess the sensitivity of species, the results were compared with samples taken at the reference site and maintained in the laboratory, and fish treated with insecticide chromagor. Our results show significant increase of number of micronuclei in erythrocytes of goldfish.
