Determination of 16 polycyclic aromatic hydrocarbons in marine sediments by gas chromatography-tandem mass spectrometry with accelerated solvent extraction

A method based on gas chromatography-tandem mass spectrometry (GC-MS/MS) with accelerated solvent extraction (ASE) was developed for the determination of 16 polycyclic aromatic hydrocarbons (PAHs) in marine sediments. The sediment samples were extracted with hexane-acetone (1:1, v/v). The extracts were dehydrated with anhydrous sodium sulfate, and concentrated with a termovap sample concentrator. The concentrated solutions were further cleaned up with Si SPE columns. The purified solutions were then isolated by HP-5MS column (30 m×0.25 mm×0.25 μm). The analytes were detected using electron impact source under multiple reaction monitoring (MRM) mode. The results showed that the 16 PAHs had good linearities in the range of 0.01-1.00 mg/L with the correlation coefficients (R) greater than 0.997. The spiked recoveries of the 16 PAHs were in the range of 75.8%-97.8%, and the relative standard deviations (RSDs) were less than 10%. The method detection limits (MDLs) of the 16 PAHs ranged from 0.048-0.234 μg/kg with 20.0 g sampling weight. This method is suitable for the determination of trace PAHs in marine sediments.
