In the present study, an effort has been made to study the status and trend of the gaseous pollutants such as Sulphur dioxide (SO2) and Oxides of Nitrogen (NOx) in the ambient air in and around the rural villages located around a Coal Based Thermal Power Plant. A large portion (85%) of the total thermal power generation is through coal burning. On combustion of coal, pollutants generally emitted into the atmosphere are Sulphur dioxide (SO2), Oxides of Nitrogen (NOx) and Carbon Monoxide (CO) along with ash. Probably the most common pollutant emitted is Sulphur dioxide (SO2). Here, the annual maximum 8 Hours concentrations of Sulphur dioxide (SO2) and Oxides of Nitrogen (NOx) data for the period of 10 years were analysed.
