Determination of Polycyclic Aromatic Hydrocarbons in Baked Fillet by GC/MS

Determination of polycyclic aromatic hydrocarbons in baked fillet was established by gas chromatography-mass spectrometry. The samples were extracted with cyclohexane after KOH-MeOH saponification and cleaned up by the columns of neutral silica gel. 16 PAHs in the samples were separated and quantified by the proposed method. The recoveries of the method range from 88.1% to 95.0%， and the relative standard deviations are 2.2%-4.7%. This method is sensitive, accurate and suitable to determinate PAHs in baked fillet.
