Opis:
Water pollution is a matter of great concern in lentic and lotic ecosystems. Generally water pollutants like heavy metals, organic compounds, etc. generate from industries and domestic activities. All of these pose serious threat to the fish population in freshwater as well as marine water bodies. An impact caused by water pollutants especially genotoxins depend not only upon its concentration, but also on the duration (acute and chronic exposure) and showed individual and/or combination of pollutants or genotoxins. Genotoxicity of fish with special reference to micronucleus induction in the erythrocytes of fish is an easy screening of water pollution. The present review deals with past and present research works of major water pollutants discharge and their impact on several fish species from available literatures.

Opis:
As far as the detection of metal genotoxicity in fish is concerned, micronucleus (MN) test is considered an extremely suitable measure. In this study, frequencies of micronucleated erythrocytes were scored in peripheral blood of catfish, Heteropneustes fossilis (bloch) after acute in-vivo exposure of zinc at different concentrations (5, 10 and 30 ppm) in the laboratory condition. These three concentrations of zinc were tested at different durations such as 24h, 48h, 72h and 96h respectively. Highly significant (P < 0.001) increased values were obtained for MN frequencies in the peripheral erythrocytes of exposed fishes compared to control groups of fishes. These results confirm that dose- and time-dependent micronucleation in the peripheral erythrocytes of fish after short-term exposure to zinc could provide valuable information regarding zinc containing effluent quality and also help in genetic biomonitoring with this test model. In this context safe concentration of zinc vis-a-vis genotoxicity range could be evaluated for future studies.
