Stone crushing unit workers suffer from particulate matters and respirable silica at work and in their residents nearby. The present study was undertaken to evaluate the area and personal exposure concentration of respirable particulate matters and silica in workplaces and in surrounding villages. PM10, PM4 and PM2.5 were considered for unit area measurement and PM4 and PM2.5 were considered for personal exposure measurements. The ambient PM10 and indoor respirable particulate sampling and analyses were carried out in two neighboring villages adjacent to a cluster of 100 stone crushing units in central India. The study was conducted in two years with varied seasons to provide baseline data on the existing particulate concentration with and without control intervention. Monitoring and analytical criteria were fulfilled according to the National Institute for Occupational safety and Health (NIOSH), USA protocol. The study reports the higher particulates and respirable silica with respect to the national and international guidelines in and around the study units. However, in nearby villages, the particulate concentrations and silica were comparatively less. An innovative dust abatement dry engineering control system was installed as a pilot work to reduce dust emission from the unit and the results afterward were found to be encouraging.<br>
