| Outline of Final Research Achievements |
Emission and transfer of diethylhexyl phthalate (DEHP) from PVC sheet to air and house dust were determined for 1, 3, 7, and 14 days using passive flux sampler (PFS). The diffusion distances were set as 0.9, 1.85, 2.75, 3.8, 5.75 mm. As the house dust, 0.3, 1, 3, and 12 mg/cm2 of JIS standard dust 15, polyethylene particle, and soda lime glass particle were used.
DEHP transfer to dust increase until 14 days. The transfer rate to dust from PVC sheet were not different among the different diffusion distanses.The transfer rates to dust were several tens times to several hundreds times higher than the emission rates to indoor air.

| Academic Significance and Societal Importance of the Research Achievements |
フタル酸エステル類の建材等からハウスダストへの移行や空気中から浮遊粒子・壁面
等への吸脱着については分かっていないことが多く、暴露推定モデルの構築にお
いて不確実性が大きい。本研究で得られたダストへの移行のデータを用いることで、室内における挙動のモデル化が可能となり、暴露評価や対策につながると考えられる。
