The subways play an important part in serious traffic problems. Almost seven million citizens a day are using subways as a means of traffic communication in the Seoul metropolitan city in 2012. However, the subway system is a semi-closed environment, so many serious problems occurred in subway stations and injured passengers’ health. Platform screen doors (PSD) are expected to prevent negligent accident such as injury or death from falling and improve the air quality of the subway station. Installation of PSD at stations in Seoul metropolitan subway had been completed in December 2009. Consequently, the underground transportation system became a closed environment, so the air quality has improved the platforms, but it has deteriorated in the tunnels. Especially, the subway cabin has many doors, 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 who work 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 study focused on the investigation of Indoor Air Quality (IAQ) and measurement target pollutants are PM<SUB>10</SUB>, CO, CO₂, NO₂, O₃. It was found that levels of PM<SUB>10</SUB>, CO₂, and NO₂ inside subway cabin line 2 exceeded the Korea IAQ standard. Concentrations of PM<SUB>10</SUB>, CO₂, and NO₂ inside of the cabin are higher than outside of the cabin (Indoor Outdoor ratio is higher than 1.). Concentrations of CO, O₃ inside of the cabin are lower than outside of the cabin (Indoor Outdoor ratio is lower than 1.). There is a high correlation between CO₂ and passengers inside of the cabin and PM<SUB>10</SUB> is 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.
