摘要
研究了鱼体中２－５环多环芳烃的分析方法．方法包括皂化、萃取、氧化铝柱色谱分组、ＳｅｐｈａｄｅｘＬＨ－２０凝胶色谱净化，以及气相色谱和高效液相色谱方法分离测定，其方法对多环芳烃的添加回收率在６０％到９８％之间，检测限为０．ｌｐｐｂ．应用本方法测定了北京地区两个鱼样体内多环芳烃的含量．
A method is described for the determination of polycyclic aromatic hy-drocarbons(PAHs with 2-5 rings in fish tissue. The analytical procedure includes following steps:saponification,extraction,column chromato-graphy on alumina,clean-up with gel permeation chromatography,gas chromatography and high performance liquid chromatography with UV and fluorescence detectors.The recoveries ranged from 60% to 98% for PAHs and the detection limit is 0.1 ppb.Results of fish samples are presen-ted. One of the samples comes from a reservoir and the other comes from afishing ground.
