어린이 활동공간의 프탈레이트류 노출로 인한 건강 위해성 평가 : 초등학교와 학원을 중심으로

Abstract

The objective of the present study was to estimate the health risk level for children exposed to phthalate and identify the pathways including indoor floor dust, surface wipe and hand wipe in elementary-schools and institutes. The samples of indoor place were collected at children's facilities (50 elementary-schools and 46 academies) in summer (Aug ~ Sept, 2008), winter (Dec 2008 ~ Feb, 2009) and Spring (Mar ~ Apr, 2009) periods. Hazard Index (HI) were estimated for the non-carcinogens and the examined phthalate were diethylhexyl phthalate (DEHP), dibutyl-n-butyl phthalate (DnBP), butylbenzyl phthalate (BBzP). Risk analysis indicates that did not exceed 0.01 (HI) for all subjects in all facilities it's 50th% and 95th% value. For DEHP, DnBP and BBzP their detection rates through multi-pathways were high and their risk based on health risk assessment was also observed to be acceptable.
