Large-scale industrialization, population inflow, and rapid urbanization coupled with unfavorable meteorological conditions often induce significant degradation of urban environment. In order to assess the extent of environmental impacts due to establishment of the industries in Nagpur City, ambient air was monitored from September 2010 to February 2011. Collected baseline information was normalized and interpreted with respect to air. Among the pre identified air pollutants, suspended particulate matter was found to be the principal culprit to deteriorate ambient air quality, with a maximum annual concentration of 270μg/m3. Monthly average concentrations of respirable particulate matter (aerodynamic diameter < 10 μm) also persist at a critical level with an annual maximum of 150 μg/m3. Monthly variation of air pollution parameters which indicates a mild control over few pollutants throughout the study period with rising in quality of analytical sampling and analysis. The result had been found to be effectively below the Central Pollution Control Board (CPCB) standards.
