[Analysis of 209 PCB congeners by high separation gas chromatography/low resolution mass spectrometer]

All PCB congeners were analyzed by high separation gas chromatography/low resolution mass spectrometer, using 209 PCB congeners as standards. They were separated into 169 peaks, including 28 peaks containing 2 PCBs and 8 peaks containing 3 PCBs. The rice oil samples of Fukuoka and Taiwan Poisonings were analyzed for PCB congeners. They showed 115 separated peaks of PCB congeners. Total PCB concentrations were 879 and 769 ppm in 2 samples of Fukuoka rice oil and 57 and 83 ppm in 2 samples of Taiwan rice oil.
