%X The analytical methods of polycyclic aromatic hydrocarbons(PAHs) in different samples,e.g.,vegetable oils,waters and soils,have been reviewed.The sample pretreatment steps play a key role during the analysis due to the very low PAHs contents.The pretreatment methods for water samples include liquid-liquid extraction,solid phase extraction,etc.The pretreatment methods for soil samples include Soxhlet extraction,ultrasonic extraction,microwave assisted extraction,accelerated solvent extraction,and supercritical fluid extraction,etc.The pretreatment methods for vegetable oils include saponification,liquid-liquid partitioning,caffeine complexation,solid phase extraction,and supercritical fluid extraction,etc.Gas(chromatography) with mass spectrometry and high performance liquid chromatography(HPLC) with fluorescence detection are mainly used for separation and detection.The novel on-line(determination) method,e.g., the coupling of liquid(chromatography) with high performance(liquid) chromatography,or with gas chromatography may obtain ideal results.Fifty-two references(are cited.)
