MONITORING OF AMBIENT AIR QUALITY AND ESTIMATION OF AIR QUALITY THROUGH APPLICATION OF AQI FOR AN INDUSTRIAL CLUSTER AROUND JHARSUGUDA, ODISHA, INDIA

摘要

Rapid and large-scale industrialization, population inflow and urbanization coupled with unfavorable meteorological conditions often induce significant degradation of urban environment as well as affect the rural environment near by the industries. In order to assess the environmental impacts on the surrounding village of the industrial cluster of Jharsuguda district, the ambient air quality was monitored at four different locations during January 2012 to December 2012. Collected information was normalized and interpreted with the application of air quality index (AQI). Among the monitored air pollutants PM_(10) was found to be the dominating pollutant to deteriorate ambient air quality. A segmented linear function with maximum operator concept was used to compute AQI. The results revealed that the concentration of the particulate matter exceeded the NAAQS standard, 2009 at almost all the locations throughout the year and all other parameters were found within the prescribed limits.
