HEAVY METAL CONTENT OF WATER RESOURCES AFTER GANAPATI IMMERSION IN A SPECIFIED REGION AND ITS PHYSICO CHEMICAL EFECTS ON WATER

Abstract

The main objective of present study was to assess physicochemical parameters in different water samples in various parts of Nalasopara region. For this 7 different water samples are collected from 4 sampling sites in Nalasopara region, to determine the various physicochemical properties on seasonal basis. In India the major source of water used to meet the domestic, agricultural and industrial needs is the ground water. The situation is aggravated by the problem of water pollution or contamination. The main goal of the present study was to assess heavy metal ions pollution in sea and pond water before and after Ganesh immersion. For this 4 different water samples are collected from sampling sites in Nalasopara town which is a part of Vasai Taluka of Mumbai suburb. Out of the four sites three are sea water samples collected on both high and low tides & one is pond water sample. Some of the heavy metals like Cd, Cu, Cr, Pb, Fe, Zn, Mn, Hg, and Ni were detected using highly sensitive ICP-AES instrument. The heavy metals were found to be in the permissible limits but Cr and Cd were not detected. The results obtained are compared with World health organization (WHO), Indian Standards (IS), European Standards and Beaureau of Indian Standards (BIS-10500:1991). The effect of presence of heavy metals on the physical-chemical parameters of water have been studied at different time intervals individually and in presence of each other.
