Emission inventory was gathered from CARD, Neyveli. The Meteorological data were observed from the Meteorological observatory at Vadalur. The hourly meteorological file was prepared and fed into MPC-SPR Model. The dispersion pattern of SO2 was mapped by using MPC-SPR Model by considering all the emissions sources at NLC India Ltd. Key words: MPC-SPR, SO2, CARD, ISCST3 etc., Cite this Article: Iyappan M, Kumaravel B and Palanivelraja S, Air Pollutant Dispersion pattern around NLC India Ltd, International Journal of Advanced Research in Engineering and Technology (IJARET), 12(2 2021, pp. 589-592. ), ttp://iaeme.com/Home/issue/IJARET?Volume=12&Issue=2 h 1. INTRODUCTION Air pollution is also life-threatening if one has to inhale poor quality of air. Thermal power plants, smelting industry, and refinery, etc are the major sources of Air pollutants. Thermal Power plants alone me about 60% of power generation in India. The thermal power stacks t emit large amount of PM, SO2, NOX, carbon monoxide, carbon dioxide and hydrocarbon into the ambient air and subsequently directly or indirectly produce harmful effects on the environment and human health.
