dc.description.abstract | Understanding characteristics of diurnal particle concentration variation in an underground subway tunnel is important to reduce subway passengers' exposure to high levels of toxic particle pollution. In this study, real-time particle monitoring for eight consecutive days was done at a shelter located in the middle of a one-way underground subway tunnel in Seoul, Republic of Korea, during the summer of 2015. Particle mass concentration was measured using a dust monitor and particle number concentration using an optical particle counter. From the diurnal variations in PM10, PM2.5, and PM1, concentrations of particles larger than 0.54 mu m optical particle diameter were affected by train frequency whereas those of particles smaller than 0.54 mu m optical particle diameter were not changed by train frequency. Number concentration of particles smaller than 1.15 mu m optical particle diameter was dependent on outdoor ambient air particle concentration level, whereas that of particles larger than 1.15 mu m optical particle diameter was independent of outdoor ambient air due to low ventilation system transmission efficiency of micrometer-sized particles. In addition, an equation was suggested to predict the diurnal particle concentration in an underground tunnel by considering emission, ventilation, and deposition effects. | en_US |
