We investigated the concentrations, congener distributions, and characteristics of polybrominated diphenyl ethers (PBDEs) in house dust samples collected from general houses of an industrial area in Korea. The mean concentration of ΣPBDEs in indoor dust samples from 20 houses was 1900 ng/g, while deca-BDE (BDE-#209) was the predominant congener accounting for 85% of ΣPBDEs. The concentration of PBDEs increased with the presence of electrical/electronic products in the indoor environment, except for the dust samples collected from the inside of TV. The congener distribution patterns were similar in nearly all samples. However, BDE- #99, BDE-#100 and BDE-#47, which belonged to Σlower-BDEs (38%), were dominant in the samples from the inside of TV, displaying a slightly different distribution from the other indoor environment conditions. Meanwhile, there was no relationship between the particle size of house dust and the PBDE concentration. The distribution patterns of congeners were also similar to those prior to re-classification (>150 μm). In this study, we concluded that the electrical/electronic products were an important factor for the concentration of PBDEs in the indoor environment, and deca-BDE was a major contaminant. Therefore, analytical methods for deca- BDE should be established for further regulatory monitoring of PBDEs from electrical/electronic products.
