Characteristics and assessment of phthalate esters in urban dusts in Guangzhou city, China

60 dust samples were collected from Guangzhou city, and analyzed for 16 phthalate esters (PAEs). The ∑16PAEs concentrations ranged from 121 to 3223 μg g-1 dust, with the median concentration of 840 μg g-1 dust. Of the 16 PAEs, diisobutyl phthalate (DiBP), di-n-butyl phthalate (DnBP), and di(2-ethylhexyl) phthalate (DEHP) dominated the PAE congeners in in- and outdoor dust samples. The median daily inhalation exposure of .16PAEs were 3.53 and 0.247 .g kg-1 body-weight day-1, and at the 95th percentile were 7.62 and 0.530 .g kg-1 body-weight day-1, up on the measured concentrations and estimated dust ingestion rates, respectively for toddles and adults.
