ABSTRACT :

Distribution of metals seawater was evaluated in Indian Ocean from Goa (India) to Antarctica via Cape Town (South Africa). Spatial difference of the heavy metal concentrations in seawater was in fluctuated manner and their concentrations were in the order of Fe> Zn> Pb> Cu> Mn> Co> Cd. Water samples were collected from 13 sampling location in Indian Ocean from latitude N 092248.2 and longitude E 670745.5 to Latitude S 670430.0 and Longitude E 130008.0 and analyzed for various heavy metals like copper, lead, cadmium, zinc, nickel, chromium, etc. The concentrations of metals Cu, Pb, Cd, Zn, Ni and Cr were measured using Inductively Coupled Plasma Optical Emission spectroscopy (ICP-OES). Besides these, other metals like sodium, potassium, calcium, magnesium, boron, etc. were also detected in selected seawater samples. The total concentrations of all metals were found slightly fluctuated in sea water samples. The results indicated that the concentrations of metals in seashore were higher than those in Inner Ocean. Sodium, potassium, calcium, magnesium, boron and iron metals were found as the dominant constituents among the sea water contents. Aluminum (0.61-15.38 g/cc), zinc (0.27-2.63 g/cc), copper (0.06-0.32 g/cc) and molybdenum (0.08-1.91 g/cc) were also found in all seawater samples. Phosphorous and arsenic were also detected in few samples. Strontium was also one of the dominant alkaline earth metals in sea water and was found to be gradually deceasing from Goa to Antarctica. Nickel was one of the rarest metals in seawater as it was found below detection level in all samples.
