Clean air is the foremost requirement to sustain healthy lives of mankind and those of the supporting ecosystem which is turn effect wellbeing. Release of particulate matter and various gaseous emissions has been on rise due to rampant industrialized growth. The ambient air quality is being deteriorated day by day due to various natural as well as anthropogenic sources. The pollutant data (RSPM, PM 2.5, NO2 and SO2 ) from State Pollution Control Board for period June 2017 to May 2018 has been used for this study . The study reveal that sampling site with heavy traffic density/load recorded the higher concentrations of RSPM, PM 2.5, NO2 and SO2 in all the seasons. Higher concentration of RSPM (178.0 �g/m3 ) and PM 2.5 (51.2 �g/m3) were observed in summer season at all the sites whereas striking feature of higher concentrations observed in case of gaseous pollutant NO2 (24.6 �g/m3) and SO2 (5.1 �g/m3) in winter season at all the sites. Lowest concentrations of all the pollutants observed in Monsoon season at all the sites. Factor analysis was carried out using Principal Component Analysis for all the four pollutants. The major sources identified in the study which were responsible for the higher concentration of pollutants are Vehicular emission (from petrol and diesel driven vehicles) and crustal re-suspension. Some contributions are from wood and leaf burning and coal combustion.
