초록

This study measured the particulate matter (PM) in a subway tunnel using a dust spectrometer and estimated thePM10 and PM2.5 using a Kriging method. For the hourly measurement, a probe was attached inside the cabin andput through the window to collect data from the outside. The Kriging method is a spatial analysis method, andtime and spatial data were applied in the subway tunnel along with a PM concentration map. The result of themeasurement shows that PM10 is 31.9~271.3 μg/m3 and PM2.5 is 30.9~209.5 μg/m3. In addition, The pollutant mapshows that some sections have a higher concentration than other sections because of the depth and curvature oftunnel and traffic volume on the section and local construction. Also, the results show that differences concentrationat different times of sampling could be distinguished. The highest concentration was found at 3 pm while the lowestwas at 12 pm. We expect to use the pollutant map in planning air quality improvements for the tunnel.
