초록

The subways play an important part in serious traffic problems. Almost seven million citizens a day are using subwaysas a means of traffic communication in the Seoul metropolitan city in 2012. However, the subway system is asemi-closed environment, so many serious problems occurred in subway stations and injured passengers’ health. Platformscreen doors (PSD) are expected to prevent negligent accident such as injury or death from falling and improvethe air quality of the subway station. Installation of PSD at stations in Seoul metropolitan subway had been completedin December 2009. Consequently, the underground transportation system became a closed environment, so the airquality has improved the platforms, but it has deteriorated in the tunnels. Especially, the subway cabin has manydoors, and the doors are frequently opened and closed. For this reason, the effect of door opening on subway cabin,dust flow inside the subway cabin. In this process, the maintenance work may influence the health of people whowork underground, as well as that of subway users (passengers).
In this study, we measured air quality inside and outside of the subway cabin line 2 in Seoul, Korea. This studyfocused on the investigation of Indoor Air Quality (IAQ) and measurement target pollutants are PM10, CO, CO2,NO2, O3. It was found that levels of PM10, CO2, and NO2 inside subway cabin line 2 exceeded the Korea IAQ standard.
Concentrations of PM10, CO2, and NO2 inside of the cabin are higher than outside of the cabin (Indoor Outdoorratio is higher than 1.). Concentrations of CO, O3 inside of the cabin are lower than outside of the cabin (Indoor Outdoorratio is lower than 1.). There is a high correlation between CO2 and passengers inside of the cabin and PM10is only the weakest correlation with passengers. Therefore, it is important to find out the emission source of NO2.
The results of this study will be useful as fundamental data to study indoor air quality of a subway cabin.
