| Abstract: | An analytical method for polycyclic aromatic hydrocarbons in marine organisms from coastal waters by chromatography-mass spectrometry was developed.The effects of scan type on method detection limit were studied.Meanwhilet,he correlation between the scale of intensity of qualitative ions and the qualitative result was evaluated.The detection limits for ten PAHs were 0.10-0.61 μg/kgt,he linear relations was goodt,he most of recoveries for PAHs ranged from 63.1% to 98.1%t,he relative standard deviations（RSDs）ranged from 3.9% to 15.2%.Finallyt,he developed analytical method has been successfully applied to the determination of PAHs in organism samples. |
