Abstract:35 indoor dust samples were collected from Nankai University dormitory. Using CH2Cl2 and ultrasonic extraction for extraction and separation, gas chromatograph-mass spectrometry (GC-MS) method was applied to analyze DMP, DEP, DBP, BBP, DEHP and DOP. And then the pollution characteristics and assessment of human exposure to PAEs from indoor dust were studied. The results showed that DEHP and DBP were the main pollutants from indoor settled dust of Nankai University dormitory, their median concentrations were 126.916 and 123.591μg/g, respectively, the sum accounting for more than 99% of the Σ6PAEs concentration. The phthalate levels and major characteristics were affected by the quantities of phthalate products, cleaning habits, ventilation and the gender of members. The total exposures of PAEs (DBP, DEHP, DEP, BBP) for students through the mouth were higher than the skin. The exposures of DBP and DEHP which were accounted for a higher proportion of the total intake of PAEs were higher in Tianjin than those in USA. The importance of students’ exposure to PAEs in indoor environment should be paid more attention.
