Distribution of certain heavy metals in the nelatur lake adjacent to Sri Damodaram Sanjeevaiah (APGENCO) thermal power plant of Spsr Nellore District, AP, India
Abstract
Coal is the only natural resource and fossil fuel available in abundance in India and is used widely as thermal energy source for thermal power plants producing electricity. Huge quantity of fly ash is produced as by product from the combustion of coal in thermal power plants and are deposited on surrounding agricultural lands and water bodies. These effluents contain the heavy metals, the most hazardous pollutants due to their speedy dissemination into biosphere and their accumulative concentrations causing serious environmental problems (Ada et al., 2007). A 600 MV Sri Damodaram Sanjeevaiah (SDS) thermal power plant is situated at Nelatur Coastal Village of SPSR Nellore Dist., AP, India. Effluents from this thermal power plant adversely affect the quality of water and directly contributes to contamination of Nelatur Lake water. In the present study the distribution of four heavy metals (As, Hg, Pb & Mn) is estimated in the Nelatur Lake adjacent to the thermal power plant. The results vividly indicate that the Arsenic level is high followed by Mercury. Lead and Manganese are relatively in low level (As>Hg>Pb>Mn).
