Prediction of SPM, SO2 and NO2 Concentrations in The Vicinity of Cement Industry Using Gaussian Model

The burning of limestone creates sulphide emissions, a major contributor to acid rain. Limestone (primarily calcium carbonate) is converted to quicklime (calcium oxide) through prolonged exposure to high heat. This removes water and carbon from the stone and releases carbon dioxide into the atmosphere. In cement industry the coal is used for heating process. Combustion of coal along with lime stone is the main source for the emission of air pollutants. This study deals with the prediction of ground level concentration of Suspended Particulate Matter (SPM), Sulphur dioxide (SO2), and Nitrogen dioxide (NO2). By using Gaussian model at various receptor points from a point source of a cement plant. Basically pollutant dispersion model is the mathematical formulation to explain how pollutants from various sources disperse in the atmosphere. The point source selected for this work is Ultra Tech Cement Ltd Andhra Pradesh Cement Works is located at Bhogasamudram, 16 km. from Tadipatri mandal in Anantpur district, Andhra Pradesh, India. Concentrations of SPM, SO2 and NOX are predicted for annual and 24 hour averaging periods at various points and compared with National Ambient Air Quality Standards.
