Selected-Ion Storage GC–MS Analysis of Polycyclic Aromatic Hydrocarbons in Palm Dates and Tuna Fish

A rapid analytical method based on Soxhlet extraction has been developed for determination of polycyclic aromatic hydrocarbons (PAH) in palm dates and tuna fish. The method is based on selected ion-storage gas chromatography–mass spectrometry. In the work discussed we were interested in the analysis of 16 polycyclic aromatic hydrocarbons (PAH) regarded by the EPA as priority pollutants. Soxhlet extraction of real, fortified, and blank samples, with hexane as solvent, was used to extract the analytes of interest. An excellent detection limit and good relative standard deviations (RSD) were obtained and analysis time was short. The linearity and sensitivity of the method for measurement of these analytes at trace levels are discussed.
