Due to an increase in the vehicle count, intensive population growth, use of fuel with deprived environmental performance, industrialization and above all ineffective environmental guidelines leads to high air pollution in this country. The aim of this study is to investigate the amount of pollutants (PM10, PM2.5, SO2, NO2, NH3 and O3) released from various sources, like vehicular exhaust, industrial emissions, etc. SIDCO-Kurichi is one of industrial clusters in Coimbatore. Six sampling points were chosen and at each location, 6 pollutants were monitored for 4 cycles. To estimate the level of impurities in the air, range of pollution index was determined by the procedure recommended by the government. The result shows that Sundarapuram had higher concentration based on pollutant level measurements and was found to have the worst air quality. From the monitoring studies, daily variations of particulate pollutants were observed with the influence of meteorological conditions indicating concentrations higher than local acceptable limits in Sundarapuram. The maximum concentrations of PM10 and PM2.5 observed in SIDCO were recorded at Sundarapuram, such as 110.35 µg/m3 and 62.33 µg/m3, respectively. The pollutant responsible for this AQI was identified as PM10; PM2.5, SO2, NO2, O3 and NH3 concentrations at all locations were within standard limits. The pollutant accountable for maximum pollution index value was found to be 108 at Sundarapuram comes under moderate category when compared to other study areas coming under satisfactory conditions. SO2/NO2 ratio values were obtained around 0.4, which means the concentration of SO2 is much less than that of NO2 due to increasing level of vehicular emissions in industrial zone. The least impact of moving vehicles was found to be at Indira Nagar, Coimbatore. The spatial distribution of pollutants gives a pictorial view showing how the pollutants are distributed at each location. This poses a great threat to the health and environment of the inhabitants.
