Abstract
The concentration of Zinc, Lead and Cadmium in alimentary tract, gill, muscle, kidney and liver of the fish Myshts vittatus from Mehadrigedda stream were determined. Different organs were selected as the affinities of heavy metals vary with different organs. Among the three heavy metals, concentration of zinc was high in all the organs followed by lead and cadmium. The concentration pattern in the different organs for each metal revealed that all metals in muscle were low while in other organs the levels varied. The concentration of heavy metals from the natural habitat was also analysed and there is some evidence that accumulation in different organs is influenced by the variations in pH and it was more in acidic pH.
