고속열차 객실의 휘발성유기화합물 및 부유미생물 분석 연구

The public interest on the indoor air quality of a high-speed train passenger cabin is drastically increasing due to the sealing of cabin. In this study, the concentration of volatile organic compounds and suspended microorganism in the high-speed train passenger cabin was investigated. There have been many studies on the indoor air quality of the high-speed passenger cabin, but the study on the indoor air quality without boarding of passengers were hardly carried out. As a result, it was very difficult to identify the exact source of air pollutants in the cabin. In this study, the indoor air quality of passenger cabin without any passengers was investigated so that the contribution of passengers as the source of various pollutants could be estimated.
