A method of gas chromatography-tandem mass spectrometry（GC-MS/MS） was developed for the determination of 8 polyaromatic hydrocarbons（PAHs）,18 polychlorinated biphenyls（PCBs） and 16 organochlorine pesticides（OCPs） in geographical original soil of bamboo shoot.The samples were extracted with acetone-hexane（1∶1,by volume） in an superpower ultrasonic bath,then purified with a Florisil composite column.The eluant was concentrated by N2 blowing,finally detemined by GC-MS/MS.42 persistent organic pollutants（POPs） were efficiently separated within 35 min,and there were good linearities for the analytes in the concentration range of 2.0-2 000.0 μg/L with their correlation coefficients（r2） of 0.995 2-0.999 8.The spiked recoveries ranged from 62.3% to 128% with relative standard deviations of 0.5%-15.8%,and the limits of detection（S/N=3） were 0.070-6.902 μg/kg.With the characteristics of easy operation,high sensitivity and accuracy,the method could be applied in the simultaneous detection of 42 POPs in original soil of bamboo shoot.
