    It is complicated to detect Polycyclic Aromatic Hydrocarbons (PAHs) contamination soil by High Performance Liquid Chromatography (HPLC) with the conventional method. the Laser-induced Fluorescence (LIF) is used to on-site detect anthracene, one of the PAHs in soil, and it is shown that the Laser-induced Fluorescence can facilitate the monitoring of the soil pollution. According to the fluorescence properties of anthracene, the optical path and sample holder are designed to directly excite the fluorescence of the mixture of anthracene and the soil sample by using Nd: YAG laser at 355 nm, and the fluorescence spectra are recorded by the fiber spectrometer. It is shown that there are obvious emission fluorescence peaks at 375 nm, 391 nm, 419 nm and 445 nm, and different mass fractions exhibit good linearity to the fluorescence intensities with the correlation coefficients up to 0.999. The effects of the changes in experimental conditions on the fluorescence properties of anthracene are studied, and it is demonstrated by experiment that it is feasible to on-site quantitatively detect anthracene in the soil by using Laser-induced Fluorescence.
