철도차량 내장재에서의 VOCs 방출 특성

Emission Characteristics of Volatile Organic Compounds from the Interior Materials of Railroad Rolling Stocks

The aim of this study is to investigate the emission characteristics of volatile organic compounds from the interior materials of railroad rolling stock. Samples for VOCs were collected using a environmental chamber and the samples were analyzed for 35 individual compounds. 6 different types of materials, seat cover and flour material of Mugunghwaho, Saemaeulho and electric rolling stock were analysed. The results were expressed as concentrations over 12, 18, 24, 36 and 48 hours. VOCs concentrations were measured to be higher in the 12 hours than in the 48 hours. Floor material of Mugunghwaho showed the highest concentration of all studied materials. Followed by floor materials of Saemaeulho and electric rolling stock.
