Resumen

This research aims to propose preventive measures for addressing health issues caused by dust exposure in a construction aggregate crushing plant. Initially, excessive dust emissions from stone crushing and vehicular traffic were identified. Monitoring using the Thermo Scientific VFC-PM10 air sampler showed a concentration value (659.68 μg/m3) exceeding ECA and WHO standards significantly. The VPC300 particle counter detected hazardous concentrations of fine dust particles (0.3 μm to 5.0 μm), indicating high exposure intensity. The quarry, the raw material source, exhibited a high SiO2 concentration (95.67% to 98.05%). A worker survey assessed personal susceptibility factors for dust-related health conditions. Control measures to mitigate dust emissions and administrative actions to reduce occupational diseases have been proposed based on these findings. Copyright
