In the paper,on the basis of linear equation solving,the authors develop a rapid analytical method that can determine the PAHs in soil samples simultaneously by the coupled approach of multivariate methods and synchronous fluorescence scanning technique,which does not require pretreatment of data,solving of large amount of data and large amount of solution preparation for internal calibration.The method is fairly successful for analysis of 15 components in a mixture solution.The linear response of this method was in the range of 0~1000ng/mL（r ≥0.9981）,the standard deviations（SD）were in the range of 0.02~4.12（n=6）.The detection limits（S/N=3） were in the range of 0.42~8.57ng/mL,and the recoveries of this method were from75.46% to108.6%.The results indicated that this method is simple and fast,suitable for the determination of trace PAHs in environmental soil.
