• In order to evaluate the pollution degree of the dust in Hangzhou City, the indoor dust samples of 19 offices, families and students' dormitories were collected from August to March in 2013 at Hangzhou for evaluating the pollution level of polybrominated diphenyl ethers (PBDEs), to analyze concentrations of 14 PBDEs congeners and congener distribution as well as the possible influencing factors, and to estimate the PBDEs exposure levels of adults and children through the dust intake. The results showed that the average ∑ PBDEs of office was 9.28×10 ng·g , and the median was 1.03×10 ng·g ; the average ∑ PBDEs of family was 7.83×10 ng·g , and the median was 9.11×10 ng·g ; the average ∑ PBDEs of student dormitory was 4.07×10 ng·g , and the median was 4.03×10 ng·g . The pollution level of the office was higher than that of the living environment. BDE-209 was the largest monomer, and its contribution was 75.48%, followed by BDE-190, BDE-154 and BDE-71.PBDEs exposure levels of adults and children by dust intake wer
