title: [Compositions and distribution characteristics of polybrominated diphenyl ethers in serum of women from Sichuan province].
abstract: The serum concentrations of polybrominated diphenyl ethers (PBDEs) in women from Sichuan province were detected via gas chromatograph-mass spectrometry in selected ion monitoring mode (SIM). Based on the experimental data, the compositions and distribution characteristics of PBDEs as well as pollution resource were also explored. Among these 11 congeners of PBDEs detected, BDE-209 was the dominant congener accounting for 63.57% -90.34% in the total PBDEs, followed by BDE-66,-99 and-100. The concentrations of BDE-209 ranged from 0.12 to 2.38 microg x L(-1) and the mean concentration was 0.63 microg x L(-1). Other congeners of these 11 PBDEs could not be detected. The data indicated that the major pollution came from deca-BDE, followed by tetra-BDE and penta-BDE. At the mean time, this result also showed that the pollution of PBDEs in Sichuan province was still at a lower level for ordinary women when compared to the data from other countries.
