Study on toxic heavy metals in Indian Carp (C.catla) and vegetation of Bhavan's College Lake of Andheri, Mumbai

0

The present paper deals with ecological study with reference to the accumulation of toxic heavy metals in the fishes and vegetation collected along the Bhavan's College Lake of Andheri, Mumbai. It was observed that the yearly average concentration of Pb, Zn, Cd, As, Cu and Fe in vegetation samples were 0.08, 0.15, 0.006, 0.45, 7.73 and 52.4 ppm respectively, which was higher than 0.05, 0.05, 0.005, 0.3, 0.04, and 42.5 ppm respectively as found in fish samples. However, yearly average concentration of Hg, Cr, Ni and Ca in fish samples were found to be 0.04, 0.25, 0.19 and 86 ppm respectively which was higher than 0.03, 0.21, 0.09 and 71.3 ppm respectively as found in vegetation samples. It is expected that the present study will be useful to understand the bio–accumulation and biomagnifications of toxic heavy metals in aquatic life.
