Spatio-Temporal Assessment of Air Pollution from Thermal Stations and Vehicular Pollution from Urban places in Tamil Nadu

India has evolved as self reliance country at all forefronts. Demand for energy is on rise due to the robust development of sectors like Automobile, Chemical, Information Technology and ITES in most part of the metropolitan states in India. There is a great deficit on energy particularly with supply chain management in Tamil Nadu. Government is exploring new ways of harnessing clean and green energy to meet out the demand. Source of energy is derived from thermal, hydro, wind, solar etc., So far and so forth, maximum energy is harnessed from thermal using coal as the raw material. Type and quality of coal determines the energy conversion ratio and the pollution emission of SO2, NOx and RSPM etc.. This study attempts to spatially and temporally explore the pollution concentration and assess with respect to Air Quality Index (AQI) of the available data on thermal power stations in Tamil Nadu. A comparison between the vehicular pollution concentrations and thermal pollution concentration has entailed us that SO2 and NOX emission was higher from vehicles and SPM was higher from thermal stations and that lead us to take precautionary measures in managing the environmental pollution. Thus this study gives an insight on the rise in pollution concentration and its effect on human health.
