英文摘要	Phthalates (PAEs) are pervasive in indoor environments. In this study, two migration pathways of di-n-octyl phthalate (DNOP) from a source to dust were investigated using microchambers in a thermostatic incubator: (1) mass transfer through direct contact with source surfaces; (2) mass transfer through air. A 20-day emission experiment with settled dust was performed at 30 °C. Significantly higher concentrations were observed in dust that was in direct contact than in dust that was not, which indicated that direct contact enhanced the sorption of the dust on DNOP. The difference between source and non-source surface was low of the migration of the DNOP in the dust. In addition, the temperature and dust loading and diffusion distance were considered. The results suggested that the temperature did not considerably influence the difference between source and non-source surface; however, the difference increased with an increase in dust loading. These results can help understand the mass transfer mechanism of PAEs to implement effective control measures and reduce the human exposure to PAEs in indoor environments. © 2021 Elsevier Ltd
