The objective of this study was to understand the content characteristic of polybrominated biphenyl ethers in indoor household dust. Polybrominated diphenyl ethers (PBDEs) are widely used as additive brominated flame retardants (BFR) in electrical and electronic equipment, and insulation in the indoor environment, and may be released indoors via volatilization or as dusts. The indoor household dust samples were collected from January to December in 2011 and measured for the concentrations, congener profiles and possible sources of PBDEs. The concentrations of 22 congeners of PBDEs (the sum of PBDEs 47, 49, 66, 71, 77, 85, 99, 100, 119, 126, 138, 153, 154, 156, 183, 184, 191, 196, 197, 206, 207 and 209) were 35.22~575.88 ng/g for apartment dust samples and 524.44 ng/g for laboratory dust sample. The eight congeners of BDE-47, 153, 183, 196, 197, 206, 207, and 209 are detected in the more than 1 ng/g. The three congeners of BDE-206, 207 and 209 in all dust samples were detected.
