Ambient air quality and indexing with reference to suspended particulate matter and gaseous pollutants around a cement plant in OCL India Limited, Rajgangpur, Odisha, India

Cement industry is a potential anthropogenic source of air pollution. Emissions from cement plants are one of the major sources of global warming. The dusts produced were very hazardous, which affect the surrounding environment. The present study was undertaken to analyse the air quality around a cement plant (OCL India Ltd, Odisha) within 2 km radius for a period of 8 months stating from October 2016 to May 2017 at four different locations with meteorological parameters. The observed values of air pollutants are found within the prescribed standards according to Central Pollution Control Board (CPCB), New Delhi. This is possible because of the initiative taken by industries by installing advanced air trapping devices. The results of this study have been presented in the form of air quality index, where we found the study area in moderate (PM10) and good category (SO2 and NOx).
