Determination of Polycyclic Aromatic Hydrocarbons in Seafood

The aim of this project is to determine polycyclic aromatic hydrocarbons (PAHs) in several seafood matrices, i.e., fish, and mussel, by the use of comprehensive two-dimensional gas chromatography-quadrupole mass spectrometry (GCXGC-MS). The procedure involves a simple extraction of PAHs, a filtration and concentration step followed by GCXGC-MS analysis. PAHs were determined in fish tissue samples by GCXGC-MS and by a standard high-pressure liquid chromatography fluorescence detector method. A Bland–Altman analysis of the two methods was performed. It indicated equivalence between the two methods. Analysis of mussel tissue (National Institute of Standards and Technology (NIST)-SRM 2974a) was performed. The results were in line with the official results of NIST.
