Abstract
Heavy metals are naturally occurring elements released into the environment through geological processes, but human activities such as mining, industry, and technology have escalated their presence, especially in aquatic habitats. The accumulation of heavy metals in aquatic organisms, particularly fish like the Rohu (Labio Rohita), occurs through various routes including gills, body surface, and alimentary canal. The thesis emphasizes the importance of understanding the toxic effects of heavy metals on aquatic organisms, encompassing not only lethality and mortality but also sub-lethal effects on behavior, growth, physiology, and biochemistry. Copper, an essential element, exhibits toxic effects on aquatic environments due to its oxidative properties. It can disrupt fish physiology, induce oxidative stress, and impact immune responses. The study underscores the need for comprehensive qualitative and quantitative assessments to evaluate the effects of pollutants on aquatic organisms. This involves investigating behavioral, physiological, and biochemical changes, as well as employing statistical analysis and mathematical modeling to predict and quantify these effects. The research contributes to our understanding of the complex interactions between heavy metals and aquatic organisms, shedding light on the environmental risks posed by increasing metal concentrations resulting from human activities. The histopathological changes in the fish liver ,kidney and gills were observed both Cooper and Arsenic.Sub lethal concentrations (LC50).
