Objectives: Subway is one of the most common transportation modes in Seoul, Korea. The objectives of this study were to determine characteristics of in-cabin PM 2.5 concentration in Seoul Metro Line Number 2 and to identify factors of the PM 2.5 concentration. Methods: In-cabin PM2.5 concentrations in Seoul Metro Line Number 2 were measured using real-time monitors and the factors affecting PM 2.5 concentration in cabin were observed. Linear regression analysis of in-cabin PM 2.5 concentration and indoor/outdoor (I/O) ratio were performed. Results: In-cabin PM2.5 concentration was associated with the in-cabin PM2.5 concentration in previous station. In-cabin PM2.5 concentration was correlated with ambient PM2.5 concentration and associated with undergroundstation with control of the in-cabin PM2.5 concentration in previous station. I/O ratio increased as the number of passengers increased and when passing through the underground station with control of I/O ratio in previous station. Conclusion: In-cabin PM2.5 concentration was affected by ambient PM2.5 concentration. Therefore, managementof in-cabin PM2.5 concentrations should be based on outdoor air quality.
