| Abstract: | Several methods are applied in the detection of PCBs in fish sample, including the national stand- ard gas chromatography, GC-MS （Gas-Chromatography-Mass-Spectrometry）, a mixed method discussed in this pa- per, which is ultrasonic extraction in conjunction with gas chromatography, microwave assisted extraction, solid- phase extraction and GC-MS. The results showed that mixed method is more efficient in the detection of PCBs and can facilitate food inspectors for quick testing of residue of PCBs. |
