Organophosphates esters(OPEs) in dust collected from the classrooms of university and residencial sites were determined using GC-MS. Concentrations and profiles of seven OPEs including Tri-n-butyl phosphate(Tn BP), Tris(2-ethylhexyl) phosphate(TEHP), Tributoxyethyl Phosphate(TBEP), Triphenyl Phosphate(TPh P), tri(2-chloroethyl) phosphate(TCEP), Trichloropropyl phosphate(TCPP) and Tridichloropropyl phosphate(TDCPP) were discussed in this work. The concentration of Σ7OPEs varied from 317.44 to 2566.97ng/g, which is lower than those reported in the developed countries. Tn BP, TCPP and TPh P exhibited high detection rates in all the dust samples. Particularly, the detection rate of OPEs was 100% for air-conditioning dust, while it was zero for the supermaket dust. The Σ7OPEs with high concentration(1836.85~2566.97ng/g) were observed in the samples related to strong human activities, such as gymnasium, dormitories, classrooms and copy shop, while it was relatively low in the parking lot(317.44ng/g). Phenylphosphate, with mean concentration of 937.26ng/g, dominated the TPh P profile(56%) in the dust from classroom, while the chloro phosphates with mean concentration of 448.12ng/g dominated the TCPP profile in the residential dust(60%). The average exposure of OPEs for adults was estimated to be 0.60ng/(kg·d). It was lower than that of children(2.51ng/(kg·d)) due to the prominent exposure path through mouth for children.
