Abstract In order to investigate the contaminant status of PBDEs in indoor air from Hangzhou, 54samples were collected by PUF-PAS from 17indoor public places from May to August and September to December in 2016, after pretreatment and GC-ECD analysis of samples, the results revealed that the geometric means of 14PBDE congeners in air samples from five typical indoor public places were in the order of netcafes (2470.43pg/m³) > building materials markets (1119.87pg/m³) > electronic markets (660.84pg/m³) > shopping malls (478.37pg/m³) > libraries (182.18pg/m³). BDE-209 was the dominant congener of PBDEs that accounting for 36.79%~56.21%, and BDE-47, BDE-99, BDE-153, BDE-183also made a significant contribution with their highest concentration of 7.77%, 7.56%, 6.32%, 7.73% of the total PBDEs, respectively. The calculation inhalation exposure revealed that the exposure level of PBDEs in netcafes was the highest and in library was the lowest, with the value of 570.10pg/(kg·d) and 44.79pg/(kg·d), respectively. Moreover, BDE-209 contributed of the total intake of PBDEs was the highest with the value of 18.44~323.70pg/(kg×d) while the value of BDE-183 was the lowest with the value of 1.75~20.05pg/(kg×d), the exposure level of PBDEs in the studied indoor public places were lower than the reference dose of EPA.
