Abstract
The present study was conducted to assess the levels of heavy metals for Mercury (Hg), Cadmium (Cd), Zinc (Zn) and Lead (Pb) in water and fish (Labeo rohita). Water and various tissues (liver, kidney and muscle) of fish were analyzed Metals for using flame atomic absorption spectrophotometer. The assessment showed Zn (1.64 mgL-1) and Pb (0.05 mgL-1) highest followed metal in water and average mean of Cd (1.28 mg/kg-1) were found to be high in the total three organs of fish were above the permissible limits than recommended benchmarks by WHO and the Food Safety Authority of Ireland (2009) and therefore, not safe for human consumption. So, there is need for a constant monitoring of the heavy metals concentrations in fresh water ecosystem.
