Effect of Particulate Matter on Stone Crushing Sites

The present study deals with the emissions of the suspended particulates (silica dust) from stone crushing industry and its effect on workers and nearby residents. A detailed air pollution survey was conducted at Chitrakoot, Banda and Mahoba of Bundelkhand, U. P. India. High volume and respirable particulate samplers were used at fifteen locations to monitor RSPM and SPM (PM10) levels in ambient air. The particle size study indicates high percentage of finer particles and silica when compared to the occupational safety and health standards posing serious health problems to the people exposed for longer duration. These emitted suspended particulate affect the environment by lowering the visibility, producing hazy condition, the health of workers and nearby residents and affecting biotic population directly or indirectly. The investigation shows that the SPM (Suspended Particulate Matter) generated by silica mining and from the loose rock pieces on the side of mines, is posing threat to the health of workers and local environment.
