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 collected 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 analyzed 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 1 × 10?⁴ ~ 1 × 10?? level in all facilities. HQs of four non-carcinogens did not exceed 1.0 for all subjects in all facilities.
