Abstract
Recently, efforts to effectively reduce particulate matter by identifying its sources and trends have become necessary due to the sustained damage it has caused in East Asia. In the case of South Korea, damage due to fugitive dust generated at construction sites in densely populated downtown areas is significant, and particulate matter in such fugitive dust directly influences the health of nearby residents and construction workers. Accordingly, the purpose of the present study was to develop a method for calculating emission factors for PM10 and PM2.5 emission amounts in the fugitive dust generated in construction sites and to derive emission amount trends for major variables to predict the amounts of generated particulate matter. To this end, South Korean emission factors for PM10 and PM2.5 for different construction equipment and activities that generate fugitive dust were derived and a method for calculating the amount of particulate matter using the derived emission factors was proposed. In addition, the calculated total emissions using these factors were compared to those calculated using construction site fugitive dust equations developed for the United States, Europe, and South Korea, and the trend analysis of total emissions according to the major emission factor variables was conducted.
Highlights
Damage caused by particulate matter accompanied by rapid economic growth in the East Asia region has emerged as a significant problem [1,2,3,4,5,6,7,8]
The PM10 emissions calculated according to site areas in this study were the closest using the Midwest Research Institute (MRI) equation [19,29]
The similarity may vary according to the silt and moisture content of the earth, which are the major variables used in the calculation of emission factors
Summary
Damage caused by particulate matter accompanied by rapid economic growth in the East Asia region has emerged as a significant problem [1,2,3,4,5,6,7,8]. According to the study by Reff et al, unpaved roads and construction sites (dust from which significantly influences the generation of fugitive dust during construction work) were found to be respectively the first and eighth among a total of 84 particulate matter (PM) emission source categories in the United States, thereby implying that the generation of PM due to construction is significant [15]. This means that residents near construction sites and construction workers could be exposed to serious health risks associated with PM.
