Objectives: This study aimed to assess the environmental factors that affect particulate matters (PM10) and tocompare with outdoor PM10 concentrations in an underground subway stations.Methods: The PM10 level was determined from May 2013 to September 2013 in the Seoul subway stations infour lines. PM mini-vol portable sampler sampler was used to collect PM10 for 6 hrs. Arithmetic means of PM10concentrations with standard deviation (SD) were calculated. Paired -test was used to compare the differencestbetween indoor PM10 and outdoor PM10 concentrations with correlation analysis which was used to identifythe association between indoor PM10 concentrations and environmental factors. Results: There were no different PM10 concentrations significantly between line 1, 2, 3 and 4 in an undergroundsubway stations. Passenger number was positively associated with PM10 concentration while construction yearwas negatively associated with PM10 concentrations. Indoor PM10 concentrations were significantly higher thanthose in outdoor PM10 concentrations. PM10 concentrations were higher in the stations which were constructedbefore 1990s rather than the stations constructed after 1990s.Conclusion: PM10 levels in the underground subway stations varied greatly depending on the constructionyear. Therefore, it might need to be more careful management to the stations which constructed in before1990s.
