This paper presents data on the concentration of air pollutants at different places of a newly developed industrial estate in a highly growing city of State of Uttarakhand, India. The out come of the study has been presented in the form of Air Quality Index(AQI). The ambient air quality survey was carried out at four different locations with respect to SO2, NO2, SPM and RSPM, and monthly air sampling was carried out for a period 24 hrs at each of the site. Pollutants concentration was used to calculate the air quality index which ranged between 62.50 to 109.0 thus categorizing the sites from moderate to heavily polluted on a five level air quality index with potential health hazards.
