Abstract A simple and accurate analytical method for determination of polycyclic aromatic hydrocarbons (PAHs) in fish and shellfish is presented, which is considered to be useful for routine analyses and for screening purposes. The procedure involves alkaline digestion, extraction with n-hexane, silica gel column chromatography, and liquid chromatographic (LC) determination with fluorometric detection. During development of the analytical method for determination of PAHs, it was found that benzo[a]pyrene, a representative PAH, was decomposed easily by the analytical procedure, and this tendency was investigated for the experimental conditions used. Benzo[a]pyrene was decomposed by the coexistence of alkaline conditions, light, and oxygen; by peroxides in aged ethyl ether; and by oxygen when adsorbed on silica gel. Thus, to obtain good recoveries and precise analytical results, these decomposition conditions must be avoided. The following precautions are recommended: protection from light through all analytical steps; addition of Na2S to alkaline digestion mixture as an antioxidant; complete removal of peroxides from ethyl ether just before use; quick column chromatography on silica gel; and prevention of air from contact with adsorbent. When this simple method was applied to fish and shellfish samples, very good recoveries of PAHs from fortified fish samples were obtained, and no serious interferences were observed in fish and shellfish extracts

The analytical method for the determination of trace polycyclic aromatic hydrocarbons (PAHs) in environmental soil by ultrasonic assisted soxhlet extraction coupled with constant energy synchronous fluorescence spectrometry was described.The results indicated that were taken in Longyan City XinLuo District of soil containing 9 components: Benzo(k)fluorathene, Anthracene, Fluorathene, 1,12-benzoperylene, 2,3-benzanthracene, 1,2,5,6-dibenzo-anthracene, Fluorene, 2,3-Benzofluorene, Coronene and that the concentrations of PA Hs are in the range of 9.344~372.986 ng.g-1. Industrial area around the PAHs were relatively higher in concentration in the soil, non-industrial area around the PAHs increased with the increase of human activity increased.
