摘要：This study assessed the lifetime cancer and non-cancer risk of aldehydes and volatile organic compounds exposure of young children at child- care facilities and indoor playgrounds in Korea. The samples were ollcted at various children' s facilities (40 day-care houses,42 child. care centers,44 kindergartens,and 42 indoor play- grounds) in summer (Jul ~ Sep,2007),winter (Jan ~ Feb,2008) and Spring (Mar ~ Apr,2008) periods,and ana- lyzed by GC-MS. We estimated the lifetime excess cancer risks (ECRs) of formaldehyde,acetaldehyde,benzene, chloroform,CCI4 and tetrachloroethylene,and the hazard quotients (HQs) of Non-carcinogens (toluene,xylene, benzaldehyde and formaldehyde). Formaldehyde evaluated both cancer and non-cancer risk. The average ECRs of formaldehyde for young children were 1x 10-+~ 1x 10~5 level in all facilities. HQs of four non-carcinogens did not exceed 1.0 for all subjects in all facilities.
