An effective method was established for the simultaneous determination of 18 banned polycyclic aromatic hydrocarbons（PAHs) in paper packaging materials contacting with foodstuffs by gas chromatography-mass spectrometry/selected ion monitor technique（GC/MS-SIM) coupled with microwave assisted extraction（MAE).PAHs in samples were extracted by MAE at 90 ℃ using dichloromethane-hexane（1∶1) as extraction solvent.The extract was firstly extracted with dimethyl sulfoxide,then reversely extracted with cyclohexane,followed by purification of silica solid phase extraction column.The analysis of targeted compounds was performed by GC-MS/SIM with the external standard method.The calibration curves were linear in the certain concentration with correlation coefficients more than 0.997.The detection limits varied from 0.1 μg/kg to 1.0 μg/kg.The average spiked recoveries ranged from 56.3% to 95.4% with relative standard deviations（RSDs) all less than 7%.The proposed method was simple,rapid,sensitive and accurate,and was suitable for the analysis of PAHs in paper packaging materials contacting with foodstuffs.
