Monitoring of air quality is mainly focused on consequences and present status of air quality of the study area. Monitoring was done at 3 different sampling locations i.e., Paravada, Vadachipurapalli and Appikonda. In the present study, four air quality parameters selected and analysed i.e., PM10, PM2.5, SO2 and NO2 at three different locations during three seasons covered within two calendar years of 2016 and 2017. PM2.5 and PM10 concentrations recorded in higher during July 2016 to June 2017 and it decreases during July-October and increases from the month of February 2017 to June 2017. All the parameters were seasonally varied, the higher in winter seasons and decreased in rainy seasons. The annual concentration of PM10 and PM2.5 were recorded at all the sampling locations were higher than National Ambient Air Quality Standard (NAAQS) during study period. Both NO2 and SO2 concentration were below the NAAQS levels during all the seasons. The present study can be reveals that the air pollution is deteriorating rapidly, and it is high time to implement the clean air act immediately to reduce such destruction.
