초록
Indoor air quality in public transportation such as railway, subway and bus is hard to control because of spatial restrict and variation of passenger's number. On January 2007, The Ministry of Environment announced "the guideline of indoor air quality in public transportation" for the concentration managements of particulate matter and carbon dioxide. In this study, we measured the PM10 concentration inside the Mugunghwa-ho passenger cabin and outdoor air and counted passengers. By the statistical analysis using SigmaPlot 2001 and SPSS 13.0, we found that indoor PM10 concentration is significantly affected by outdoor air. It is suggested that the air quality of inflow to the passenger cabin for air exchange must be controlled to support the indoor environment comfortably.
