摘要: 多环芳烃是一种有毒、致癌、难降解的持久性有机污染物,环境中90%的PAHs最后都富集到土壤中,土壤PAHs污染问题尤为突出。因此,实现土壤中PAHs快速、现场检测对土壤污染调查、环境治理、生产生活有着重要现实意义。相比传统检测方法,荧光光谱法有选择性好、灵敏度高、检测限低等诸多优点,已被广泛应用于土壤中PAHs的检测。文章综述了近年来常规荧光光谱、三维荧光光谱、二维荧光相关谱、激光诱导荧光光谱直接检测土壤中PAHs的应用与研究进展,分析上述荧光光谱检测技术的各自特点与适用情况,重点论述了荧光光谱技术在PAHs特征信息提取、定量分析、土壤理化性质对PAHs荧光强度影响及校正等方面的应用,并进行了展望,为进一步实现荧光光谱技术直接检测土壤中PAHs提供参考。

Abstract: Polycyclic aromatic hydrocarbons(PAHs)are a kind of toxic, carcinogenic, hard-to-degrade persistent organic pollutants, 90% of PAHs in the environment are finally enriched in the soil, and soil PAHs pollution is particularly prominent. Therefore, the realization of rapid and on-site detection of PAHs in soil is practically significant for soil pollution investigation, environmental management, production and life. Compared with traditional detection methods, fluorescence spectrometry has many advantages such as good selectivity, high sensitivity and low detection limit, and has been widely used for the detection of PAHs in soil. The article reviewd the application and research progress of conventional fluorescence spectroscopy, three- dimensional fluorescence spectroscopy, two-dimensional fluorescence correlation spectroscopy and laser-induced fluorescence spectroscopy for the direct detection of PAHs in soil in recent years. The application of fluorescence spectroscopy is discussed in the extraction of PAHs characteristic information, quantitative analysis, the influence of soil physical and chemical properties on PAHs fluorescence intensity and correction, etc. and the prospect were discussed to provide reference for further realization of fluorescence spectroscopy technique for direct deaction of PAHs in soil.

Key words: fluorescence spectroscopy, polycyclic aromatic hydrocarbons, soil, development trends
