Air quality of a steel city, rourkela, orissa

The iron and steel industry is an important basic industry because of high demand of iron and steel utilization, and the production process necessarily produces a significant volume of dust as well as gaseous effluents. An air quality monitoring program has been designed to collect the gaseous and particulate air pollutants from two sites (in front of Indira Gandhi Park & Udit Nagar) of the steel city, Rourkela. The PM10, TSP and gaseous air pollutants sulfur dioxide (SO2), nitrogen dioxide (NO2),ammonia (NH3) &carbon monoxide (CO) will be measured by high volume sampler .The average SO2,NO2,NH3,CO,PM10 and TSP concentration at Uditnagar (Residential site) during weekdays are 0.0155ppm, 0.3396ppm, 0.5119ppm, 0.70ppm, 24.50 µg/m3 and 158.38µg/m3 respectively. The average SO2, NO2, NH3, PM10 & TSP concentration at Uditnagar during weekends are 0.0179ppm, 0.2302ppm, 0.3238ppm, 0.75ppm, 8.57µg/m3 and 159.49µg/m3 respectively. The average SO2, NO2, NH3, PM10 & TSP concentration at Indira Gandhi Park (Industrial site) during weekdays are 0.0198pm, 0.2701ppm, 0.6744ppm, 0.54ppm, 17.76µg/m3 and 169.41µg/m3 respectively. The average SO2, NO2, NH3, PM10 & TSP concentration at Indra Gandhi Park weekends are 0.0193ppm, 0.2807ppm, 0.7847ppm, 0.24ppm, 22.81µg/m3 and 156.46µg/m3, respectively
