Phthalates are widely used as plasticizer and associated with various health issues. Recently, non-phthalate plasticizers replacing phthalates; however, the exposure to these substances risk in Japan is unclear. In this study, we assessed concentrations of phthalates, plasticizers, phthalate degradation products house dust determined their respective risks via oral dermal routes. Twelve seven two were obtained from 100 Japanese homes. The median concentration di(2-ethylhexyl) (DEHP), accounting for 85 % total phthalates detected was 2.1 × 10
