Abstract

Heavy metal pollution in aquatic environments threatens marine life and lowers the quality of freshwater supplies. This research aimed to quantify the heavy metal concentration in fish, avian tissue, and water of the Mangla reservoir. Concentrations of heavy metals such as Cu, Cd, Cr, and Pb were determined in five vital organs of six species of fishes (Cirrhinus cirrhosis, Catla catla, Hypophthalmichthys molitrix, Wallagu attu, Cyprinus carpio, Sperata seenghala) and five species of migratory birds (Anas strepera, Aythya ferina, Anas platyrhynchos, Anas crecca, Anas clypeata) and water of Mangla dam. Heavy metal concentration was observed with AAS’ help after the samples’ complete chemical digestion. The average concentration of these metals in water samples was higher than the mean values in fish and birds. Heavy metals damaged fish and birds in the same order: Cd > Cu > Cr > Pb. The results of this research will hopefully prompt further consideration on the dangers of heavy metal contamination in freshwater ecosystem.
