Concentration Levels of Heavy and Trace Metals in the Fish and Relevant Water from Rawal and Mangla Lakes

Muhammad Gulfraz, Tahira Ahmad and H. Afzal

Abstract:
A study was carried out to investigate the quality of drinking water for which water and fish samples of Rawal and Mangla lakes were analyzed for heavy and trace metals by Flame atomic absorption spectrometer. The metals present in the highest concentration were in the order of Fe>Ni>Mn>As>Cu in the water samples of Rawal lake, whereas Fe>As>Cu>Cr>Pb were high in the water samples of Mangla lake. In general, the metals were present in higher concentration in water samples as compared to fish samples caught from both lakes. The higher concentration of various metals in water and fish samples of Rawal lake is probably due to the addition of untreated domestic wastes. The reason for higher concentrations of various metals in the water and fish samples of Mangla lake is due to geological weathering of those areas. On the basis of results obtained we can predict that if present situation of water pollution continues then in the future survival of fish population and other animals will be extremely difficult.
