Toxic Metals Analysis in Zabi Dam Fishes Collected from District Karak, Khyber Pakhtunkhwa, Pakistan

Abstract

Heavy metals above their permissible limit are extremely threaten for animals and other microbes, so its acquire attention to study and to find solution. It was therefore of interest to conduct study to estimate accumulation of heavy metals in fishes of Zabi Dam Karak Pakistan. Zebi dam is located on North East of Karak city. Three samples of fishes namely Labeo rohita (rahu), Cyprinus carpio (Common Carp) and Goldfish collected randomly from different sides of Zabi dam. Samples were analyzed for these selected heavy metals cadmium, zinc, iron, copper, nickel and lead. The pattern of decreasing concentrations for fishes on average showed the following result Fe>Pb>Zn>Cu>Ni>Cd in which Pb showed highest average result while Cd and Ni Showed lowest. In all the three parts of head, abdomen and tail Labeo rohita the highest concentration is shown by Fe (9.501mg/kg) in head while lowest concentration shown by Ni and Cd (0 mg/kg) in all parts. In case of Cyprinus carpio Pb has the highest level (26.28 mg/kg) among all metals in head while lowest (0 mg/kg) concentration showed by both Ni and Cd.
