IMPACT OF HEAVY METALS ON BIOCHEMICAL CONSTITUENTS IN THE TISSUES OF CYPRINUS CARPIO

A. Paritha Bhanu*

ABSTRACT

The LC50 96hr values were found to be 1.0% for zinc and 1.5% for both cadmium and lead with reference to Cyprinus carpio. To assess the long term toxicity of the heavy metals, the fishes were exposed to the subthal concentrations of metals for 30 days from the metal – treated fishes, liver, kidney and muscle were collected and processed to estimate total carbohydrates, total proteins and total lipids. There was an overall reduction of the above biochemical constituents in the fishes indicating altered biochemical machinery with disturbed metabolism in the fishes.
