Seven representative indoor air samples were collected using a medium volume sampler on a university campus. The species and concentrations of polybrominated diphenyl ethers(PBDEs)were analyzed using GC-ECD and GC/MS. The results showed that 14 PBDEs were detected in the samples. Among the detected PBDEs, detection of BDE-17, BDE-28, BDE-47, BDE-99, BDE-100, BDE-153, BDE-190 were 100%. The total concentration of PBDEs(∑14PBDEs)ranged from 78.1 to 414.0 pg/m3 with the mean concentration of 266.6 pg/m3, and BDE-100 was the dominant congener. The indoor air pollutants were mainly Penta-BDE, followed by Octa-BDE commercial products. It indicated that PBDEs concentration variations were large in different rooms. The number of electrical equipment, the number of furniture and the year of decoration were important factors to affect the concentration variations of PBDEs.
