Abstract

This study assessed the health risk of trace elements in indoor children-facilities by multi-pathwaymeasurements (Air, Dust, Wipe, Hand washing). The samples of indoor place were collected at various children'sfacilities (40 day-care houses, 42 child-care centers, 44 kindergartens, and 42 indoor playgrounds) in summer(Jul~Sep, 2007) and winter (Jan~Feb, 2008) periods, and analyzed by ICP-MS. The lifetime Excess Cancer Risks(ECRs) were estimated for carcinogen trace elements such as As, Cd, Cr and Ni. For carcinogens, the ExcessCancer Risk (ECR) was calculated by considering the process of deciding Cancer Potency Factor (CPF) and AgeDependent Adjust Factor (ADAF) of the data of adults. Both Hazard Quotients (HQs) and Hazard Index (HI) wereestimated for the non-carcinogens and children sensitivity trace elements like Cd, Cu, and Cr. The average ECRsfor young children were 1×10-10~1×10-6 (50%th percentile) level in all facilities. Non-carcinogens and Children'ssensitivity materials did not exceed 1.0 (HQs, HI) for all subjects in all facilities. For trace elements theirdetection rates through multi-pathways were not high and their risk based on health risk assessment was alsoobserved to be acceptable. In addition, through education on the risk of multi-pathway exposure of traceelements for managers of facilities as well as for users the risk control of exposure of children.
