STUDY OF THE HEAVY METAL ACCUMULATION IN THE TISSUES OF FISH FROM PUNE-RIVERS-INDIA

YAZDANDOOST and M.S. KATDARE

Abstract

One of the consequences of technological progress and industrial revolution has been the release of a large nUrnber of chemicals into environment. The heavy metal toxicity is the inherent capacity of the metal to affect adversely any biological activity. The adverse effect is due to the non-degradation of metals leading to accumuLation in tissues and an interaction of the metal with a protein or enzyme leading to changes in physiologic and metabolic processes. The metalloids, and high concentrations of transitional metals, tend to accumulate in different tissues of body, and hence become bioaccumulated. The bioaccumulation through food chain leads to biomagnification, which causes severe physiologic abnormalities.
