英文摘要	A simultaneous analytical procedure for mono-ortho-polychlorinated biphenyls (PCBs), non-ortho-PCBs, polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs) in environmental samples was developed. After Soxhlet extraction, extracts were preliminary purified by a multi-layer silica gel column, then one activated carbon/celite (18%, w/w) column was used for the separation of mono-ortho-PCBs, non-ortho-PCBs and PCDD/Fs from matrix interferences. Each collected fraction was finally analyzed by high resolution gas chromatography coupled with high resolution mass chromatography (HRGC/HRMS). The procedure provided advantages of complete separation of these three groups from each other compared to the authorized methods or most of the currently available methods. The entire procedure was validated by the analysis of certified reference sediment sample (DX-3).; CPCI-S(ISTP); 18-26
