Water resource pollution is a significant issue that is only becoming worse even with the appropriate laws in place. Because effluent contaminants tend to accumulate in aquatic species, genotoxic researches on these pollutants are crucial. Therefore, using aquatic organisms to measure Genotoxicity is a highly helpful environmental monitoring technique. River Ami is a significant body of water in Maghar Sant Kabir Nagar, Uttar Pradesh, India that was contaminated by many industrial sources' untreated effluents. The current study set out to assess the genotoxic effects of these effluents on Channa punctatus fish as well as their toxic impacts on water quality. The research of Genotoxicity (the impact of bleached effluent on fish micronuclei) was conducted using the micronuclei. Fish treated with bleached effluent showed a significant (p<0.05) increase in the quantity of micronuclei compared to fish that were directly collected from the Aami River. Temperature, pH, DO, BOD, COD, TSS, and TDS are among the physico-chemical characteristics of a body of water that are assessed seasonally. All of these metrics were significantly higher than the Central Pollution Control Board of India's suggested tolerance limit.
