| Abstract: | 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. |
