Mining activities produce large quantities of particulate matter (PM) of varying sizes, posing significant environmental and health risks. In this study, five OPC N3 PM sensors and one portable aerosol spectrometer were strategically deployed at different mining locations, such as mine periphery, belt conveyor, railway sidings, and unpaved roads within an iron ore mining complex to quantify PM mass concentration. The findings revealed that the mean concentration in these locations varied from 25–37 μg m−3(PM1), 54–66 μg m−3(PM2.5), and 122–165 μg m−3(PM10). The highest coarse (PM10) and fine (PM2.5) concentrations were recorded at unpaved haul roads. At the same time, the railway sidings was found to be the predominant source of PM1.

摘要

Mining activities produce large quantities of particulate matter (PM) of varying sizes, posing significant environmental and health risks. In this study, five OPC N3 PM sensors and one portable aerosol spectrometer were strategically deployed at different mining locations, such as mine periphery, belt conveyor, railway sidings, and unpaved roads within an iron ore mining complex to quantify PM mass concentration. The findings revealed that the mean concentration in these locations varied from 25–37 μg m−3(PM1), 54–66 μg m−3(PM2.5), and 122–165 μg m−3(PM10). The highest coarse (PM10) and fine (PM2.5) concentrations were recorded at unpaved haul roads. At the same time, the railway sidings was found to be the predominant source of PM1.
