Abstract
This study assessed the health risks of elementary school students' exposure to PBDEs via different possible pathways in children's facilities. After PBDE contamination was measured, exposure was demonstrated to occur through multiple routes, including inhalation of indoor dust, dermal contact with products' surfaces and children's hands, and incidental dust ingestion. Samples were collected from various children's facilities (30 elementary schools, 31 private academies, 12 living rooms and bedrooms in houses, 5 public libraries of children's literature, and 3 large hypermalls) in summer (Jul–Sep, 2008) and winter (Jan–Feb, 2009). The hazard index (HI) was estimated for non-carcinogens and PBDEs, such as TeBDE, PeBDE, HxBDE, OcBDE, and DeBDE. PBDEs were detected in all floor dust samples, 99% of indoor air samples, 94% of product-wipe samples, and 86% of hand wipe samples. The average levels of PBDEs ranged from 0.19 to 1.06 ng/m3 in indoor air, 4623 to 6650 ng/g-dust in floor dust, 0.012 to 0.103 ng/cm2 on product surfaces, and 7.89 to 25.38 ng/hand on the surface of children's hands. The HI for school children via multimedia and multipathway exposure to PBDEs did not exceed 1.0. The exposure to PBDEs at home (approximately 80%) was dominant. The contribution rates of PBDE risk were 77% and 15% via dust ingestion at home and at elementary school, respectively; thus, intake of floor dust was determined to be the primary route of exposure.
