아산지역 도로변 구두 수선대의 이산화질수 농도 = Indoor and Outdoor NO2 level of Shoe-stall near road in Asan

다국어 초록 (Multilingual Abstract)

Workers who work at indoor and outdoor environment near busy road are suspected to be exposed to high-elevated air pollutant levels for workers (repairmen and polishers) pf shoe-stalls. Since shoe-stalls have particularly been located near busy road in Korea, workers might be high exposure to NO2 from traffic exhaust as well as indoor sources of shoe-stall such as portable gas range (butane gas) during working hours. In this study, we measured the ontdoor and out door NO2 concentrations of shoe-stall. Simultaneously, outdoor NO2 concentration of building though sidewalk from shoe-stall were measured. High NO2 exposure for workers of shoe-stalls was considered to be inflow of outdoor source of exhausted emission from vehicles and indoor source from usage of gas range to polish the shoe. Indoor/outdoor NO2 concentration ratio 1.06±0.34 in Asan, because usage of gas range was prevalent in Asan.
