摘　　要：介绍了橡胶制品中多环芳烃(PAH)的危害及来源,采用气质联用(GC/MS)结合内标法,建立了测定橡胶制品中18种PAH含量的方法。制品的超声波提取液经GC/MS选择离子监测模式采集数据后,根据内标法建立标准曲线,计算其中的PAH含量。经精密度和回收率验证,本方法灵敏、准确、可靠,适用于橡胶制品中PAH含量的测定。The hazards and sources of the polycyclic aromatic hydrocarbons （PAHs） in the rubber product were introduced, and a method of testing the content of 18 appointed PAHs in the rubber product was established by gas chromatography/mass spectra （GC/MS） combined with the internal standard method （ISTD）. The data of each sample ultrasonic extract was collected by selected ion mo- nitor （SIM） of GC/MS, and the content of 18 PAHs was calculated according to the standard curves established by ISTD. This method was sensitive, accurate, reliable and suitable for the determination of PAHs in the rubber products according to the data of precision and recovery.
