Application of GIS in Visualization and Assessment of Ambient Air Quality for SO 2 and NO x in Sheikhupura City, Pakistan

Air Pollution is the most detrimental form of pollution in our environment. A significant increase has been seen in atmospheric pollutants sources in Asia while it is considered to be primarily an urban problem in Pakistan. Sheikhupura was selected as study area and data was collected randomly from 15 different points of Sheikhupura city. Data used in this research paper is of secondary type collected from EPD, Sheikhupura. One-way-ANOVA and Interpolation (IDW and Kriging) has been applied for the interpretation and analysis of NO x and SO 2 concentration at sampling sites. Results showed that concentration of NO x was very high at areas with high road traffic while that of SO x varied differently. The highest value of NO x found in the study area is 5 ppm while the lowest value is 0.06 ppm, on the other hand the highest value of SO x found in the study area is 1.9 ppm and the lowest value is 0.1 ppm.
