The isotope dilution technique was applied for the analysis of new polybrominated diphenylethers (PBDEs) calibration standard (both labeled and non-labeled) using high-resolution gas chromatography-high-resolution mass spectrometry (HRGC-HRMS). The relative response factor (RRF) and relative standard deviation (RSD) for new calibration standard in Finnigan Thermo Electron (MAT-95XL) and Micromass (Autospec Ultima) were more or less identical with mean RRF (0.9882), RSD (0.0865) and CV% of (8.75). The results also revealed for DeBDE-209 quantification; labeled DeBDE-209 is essential. Furthermore, we recommend on column injection technique with a thin film instead of splitless injection in order to reduce the thermal degradation of DeBDE-209 and formation of octabromodibenzofurans (OBDF). Besides, analysis of human blood (n = 156) of FEBRA-intake and non-FEBRA-intake individuals elucidated frequent detection of eighteen PBDE congeners. The average PBDE concentrations in non-FEBRA intake and FEBRA-intake humans were 6000-11,000 (mean: 8400) and 5400-15,000 (mean: 9900) respectively on pg/g fat basis. Although FEBRA-intake individuals showed slightly greater PBDEs, computer-normalized concentrations of TeBDE-47 corroborate FEBRA-intake individual from four family showed reduced concentrations. The contamination profiles of PBDEs varied in between family, gender as well as geography. International comparison with predominant PBDE congener (TeBDE-47) prevailed lower levels in Japan when compared to Korea, Germany and USA nevertheless, congener specific profiles were different which is in accordance with different technical PBDE usage in between countries.
