Distribution of Polycyclic Aromatic Hydrocarbons in River Sediments by Isotope Dilution-Tandem Mass Spectrometry

Abstract: Determination of polycyclic aromatic hydrocarbons in river sediments was established by isotope dilution-tandem mass spectrometry. The samples were extracted by accelerated solvent extraction, cleaned by florisil and determined by GC/MS. This method is sensitive ,accurate and suitable to determine PAHs in river sediments.
