Interference Study of Pollutants Released from Various Industrial Areas in a Region: A Case Study

Jodhpur is well known city of Rajasthan state in India and is a tourist place. Jodhpur is surrounded by industrial areas and defence installations. Air pollution is now becoming a challenge to the administration of a city because of its adverse effects on human beings. In this study four monitoring stations were selected to find pollution level in the ambient air. Air Quality Index was calculated by considering five pollutant parameters i.e. SO2, NO2, PM10, PM2.5, CO at all monitoring stations. Minimum, average and maximum air quality index were calculated at each industrial area monitoring stations. It was observed that PM10 and PM2.5 are responsible air pollutants which governs the air quality index. In this study duration weather was clear and wind direction was either from North direction or from North-East direction. SCREEN3 Air Dispersion Model was used to find the pollutant concentration with increasing distances from area sources. Modelled AQI was also calculated before and after overlapping zone using SCREEN3 Air Dispersion Model. It was observed that air pollution from one industrial area is interfering the AQI of other industrial area.
