Vehicles, especially diesel-using, are a major source of airborne particulate matter(PM), nitrogen dioxide($NO_2$) and so on in metropolitan cities such as Seoul. Therefore workers, who are mainly merchants, near roadside may be highly exposed to air pollutants from exhausted emissions of vehicles. This means that occupational type and location can affect the workers＇health by exposure to outdoor pollutions of ambient as well as indoor pollutions of working condition, respectively. In this study, we simultaneously measured the PM3.5 and $NO_2$concentrations in indoor and outdoor of shoes repair shops in Seoul, which were generally located at roadside in Korea. Shoes repairmen were highly exposed to PM3.5 and $NO_2$ both indoor and outdoor of repair shops comparing with other sub-population groups. High exposure to air pollutants for shoes repairmen was considered to be outdoor source from exhausted emission of vehicles and indoor source from working condition. The $PM3.5/NO_2$ concentration ratio was $1.17{\pm}$0.59 in roadside, of which ratio was higher 7han ratios of other studies. This result suggested that major air pollutant in Seoul was fine particle. Also, this PM3.5 to $NO_2$ ratio will be used in environmental exposure and risk assessment by estimation of PM3.5 concentration as measuring the only $NO_2$ concentration with small and accurate $NO_2$ passive sampler.

세계 여러 나라에서는 구두를 닦거나 수선하는 직업에 종사하는 사람들이 있고 우리 나라 역시 그렇다. 그러나 우리 나라 구두기능 미화원들의 작업환경은 독특한 형태로서, 우리 나라는 1991년 8월부터 서울시내 도로변(人道)에 구두수선대라는 명칭으로 구두수선박스가 곳곳에 점유하고 있다. 본 연구는 도시지역 대기오염의 주 요인이 차량임을 고려하여 도로변 구두수선대 실내 및 실외의 PM3.5와 이산화질소(NO$_2$)를 측정하였고, PM3.5/NO$_2$ 농도비를 계산하였다. (중략)
