This investigation represented the assessment of ambient air quality with respect to PM10 (RSPM), SPM, Oxides of Nitrogen (NOx) and Sulphur Dioxide (SO2) for the year 2013 at three different sites (Industrial, Residential and Urban). The AQIs were calculated using IND-AQI procedure. It has been observed that the calculated AQIs values for SOx and NOx fall under 'good' and 'good-to-moderate' categories. The calculated AQI value of SPM and RSPM for all areas are more than the prescribed standards given by Central Pollution Control Board, New Delhi, India. The overall AQI was found to fall under the category 'moderate' and 'poor' owing to RSPM and SPM, respectively. Thus it is observed that SPM is critical pollutant at these three sites in Udaipur.
