Monitoring Study on Dust Dispersion Properties during Earthwork Construction

Dust generated in earthwork construction activities can seriously affect the air quality at a site and have adverse effects on health of workers. To accurately quantitively analyze distribution characteristics dust effect prevention measures during under normal with control measures, multiple collection points one meteorological parameter point were placed site. From half an hour before to after construction, particle concentration was recorded once every minute. The monitoring results indicated that there significant positive correlation between number soil shipments. highest earth excavation site, followed by area waste truck’s transportation path. Earth primarily resulted generation many coarse particles, which near average increments PM2.5 TSP (total suspended particulate) caused 55.06 375.17 ?g/m3 respectively. increment decreased 72.01% 40.16%, respectively, when spray system artificial sprinkling adopted. Through methodology this study, companies systemically plan their work considering key equipment be used effectively manage pollutants found within sites.
