In recent years, indoor air pollution due to phthalate esters has gained increasing attention. In particular, phthalate esters present in house dust have been reported to have a considerable impact on infant health. This study was investigated the concentration of phthalate esters in indoor air and house dusts in residential houses (n=21). Collected indoor air and house dust were analyzed for 11 substances. As a result, phthalate esters concentrations in indoor air were 0.7~29.3 g /m3 for 2E1H, 0.1~2.0 g /m3 for D6, 0.1~0.9 g /m3 for DBP and 0.1~1.2 g /m3 for DEHP. The concentrations of DEP, TBP, D6, BHT and DBA in house dust were less than detection limit. But, these were detected for TCEP (20~40 g/g), DOA (2~70 g/g), DBP (15~200), DEHP (50P:810( g/g) 95P:4660( g/g)). Assuming that an infant intakes 10.3 mg/kg/day of house dust in 95 percentile, infants would intake 47.9 g /kg/day DEHP which exceeds the guidelines for tolerable daily intake (TDI) and reference dose (RfD).
