Abstract
The level of metals (Zn, Fe, Pb, Cu, Mn, Cr, Na, Mg, Ca and K) in water, sediment and fish samples from Itapaji dam for both dry and wet seasons in two years were determined using standard analytical methods. The concentrations of metals were higher in dry season than those of wet season for the two years of study. In all the samples, concentrations of metals in sediment samples were higher than those of fish samples while the concentrations of the fish samples were higher than that of water samples. However, concentration of metals in water and fish samples were below the safety limit, hence the water can be purified for domestic use and the fish sample can be consumed by man. A close monitoring of the dam year by year is necessary.
