Water is the lifeline of our planet, essential for all forms of life to thrive. Its presence sustains ecosystems, regulates climate, and is crucial for human health and agriculture. As a universal solvent, water plays a vital role in shaping landscapes and supporting biodiversity, making it indispensable for the health and sustainability of both life and Earth. The present study exposed the freshwater fish Cirrhinus mrigala to aluminum chloride to evaluate its toxicological effects. This study determined the lethal concentration (LC50) of aluminum chloride in the freshwater fish Cirrhinus mrigala to be 0.087 ml/L after 24, 48, 72, and 96 hours. In order to evaluate the toxicological effects of aluminum chloride on brain tissues of Cirrhinus mrigala, the sublethal concentration (1/10th of LC50),.e., 0.0087 ml/L, was given to the fishes for 7, 14, 21, and 28 days. After exposing the fish Cirrhinus mrigala to aluminum chloride for 7, 14, 21, and 28 days, we observed behavioral changes like erratic swimming, hyperventilation, and aggressiveness. In the present study, after the exposure of aluminum chloride sublethal concentration to Cirrhinus mrigala, observed histological alterations in the brain tissues revealed by the necrosis in nerve cells, edema, aggregation of glial cells, and structural degeneration during the acute study, when compared to the control group. The overall results emphasize the necessity of rigorous monitoring and regulation to mitigate the adverse effects of pollutants on freshwater ecosystems and their inhabitants. by prioritizing the preservation of water quality to safeguard the delicate balance of aquatic life within these vital habitats for the benefit of both current and future generations. More studies on the effects of such chemical substances are required to be done in the fields of aquatic toxicology.
