The air pollution is most predominant present situation. This case study mainly states that the concentration of air pollutants over coastal and urban areas by using histograms. In this article the important parameters are SO2, NO2, RSPM and TSPM in μg/m3 from the period of 2009 to 2013.The concentration of TSPM (Total Suspended Particulate Matter) in both stations is high when compared with other parameters. The aim of this case study is consider the pollution concentration over coastal industrial area (Visakhapatnam) and urban metropolitan city of Vijayawada especially in Industrial and residential areas. In the month of January the pollution concentration is present high in Visakhapatnam than the Vijayawada. But in the year of 2009 the annual pollution concentration is higher in Vijayawada when compared with Visakhapatnam area. In the year of 2010 the pollution concentration is greater in Vijayawada from January to December. Over Visakhapatnam city the pollution concentration is higher in the months of April and May when compared with Vijayawada station. But in the monsoon (June to September) season the concentrations are less than Vijayawada. But in the post monsoon period over the Vijayawada high concentration is present than Visakhapatnam in the year of 2011.In Vijayawada city in the year of 2012 annual concentration is greater than Visakhapatnam over the industrial areas.
