Abstract

Osteobrama vigorsii an endemic species from Western Ghats of Maharashtra is been widely consumed by the local population in fresh form as well as dried form. A study was undertaken in the month of January, 2013 to find out the distribution heavy metals in gills, liver, kidney and muscles. Five heavy metals (Fe, Zn, Cd, Ni, Pb) were detected. Atomic Absorption spectophometer technique was implemented in the study. Iron and zinc were most abundant in all fish tissues under investigation. Iron, zinc and copper recorded highest concentration levels in liver while cadmium, and lead recorded their highest values in muscles. The level sequence of the elements studied was Fe > Zn > Cd > Ni> Pb. The observed heavy metals concentrations in these organisms were below the recommended limits for human consumption.
