Adverse effect of chromium (VI) on genotoxicity, histology of brain and behavioral patterns of fish Channa punctatus (Bloch, 1793)

Nearly all of India's regions' water sources endure an intolerable burden harmful pollution. Aquatic contamination is a result waste product discharge and anthropogenic runoff. The environment has turned into repository for chemical contaminants that seep estuaries other aquatic environments, immobilising the biota, including heavy metals. Heavy metals like chromium can be both helpful destructive to living things. It highly carcinogenic poisonous. Chemical are released by numerous enterprises. Chromium among many present in these disposals. Because Channa punctatus readily available popularly consumed freshwater fish, it was selected as test species. experiment conducted over course 28 days 4 distinct aquariums, 3 which contained at various concentrations (Group 2- LC50/5; 20 mg/l, Group 3- LC50/10; 10 4- LC50/20; 5 mg/l), one aquarium 1) served control. With increase concentration metal, exposed fish exhibited more irregular swimming became sluggish. Moreover, chromosome damage induced exposure increased production micronuclei interphase cells toxicant concentration. findings indicated acute toxicity significant negative impact on normal histology brain, genotoxicity behaviour, may population ultimately humans who eat fish.
