음식점 실내 이산화질소 노출에 관해 연구

Nitrogen dioxide (NO2) has been demonstrated to produce many adverse health effects on human. NO2, as important air pollution, has received more and more considerable attention in recent years. The purpose of this study was to investigate NO2 exposure levels in roadside restaurants. This study used multiple measurement method to investigated indoor and outdoor NO2 concentrations. The mass balance model was used to estimate the indoor and outdoor contributions to indoor NO2 concentrations. Indoor NO2 concentrations in restaurant 3 exceeded the Korean Environment Standards, and indoor NO2 concentrations in all restaurants exceeded the Korean Indoor Air Quality Standards in spring. Indoor NO2 concentrations in restaurant 3 only exceeded the Korean Indoor Air Quality Standards in summer. The I/O ratios of restaurants were all higher than 1 both in spring and summer. And the indoor contributions in all restaurants also were dominant in indoor NO2 concentrations both in spring and summer.
