Ambient air quality at granite mining site and it’s adjoining residential areas in jhansi city (uttar pradesh) india

Ambient air quality in rural residential area nearby granite mining is directly linked with activity level in the granite crushing site including drilling, blasting, loading of waste, crushing of ore and transport of overburden. Surface mining creates more pollution in comparison to underground mining. The mining activities mainly contribute RSPM and SPM to the surrounding environment. Seasonal average and range value also been calculated. It has been observed that the average concentrations of the SPM and RSPM are high in winter in comparison to the summer, monsoon, spring and autumn season. It was noticed in this study SPM and RSPM levels at all selected sites exceeds the prescribed limits as stipulated by central pollution control board (CPCB) New Delhi besides SPM in monsoon season. The average ambient air concentration of SO2 and NOx were found below the permissible limits of CPCB at all the sites. Comparatively higher concentration of SO2 and NOx were observed during winter season at all the sites.
