摘　　要：以高效液相色谱（ＨＰＬＣ）为分离手段，偏振同步荧光法为检测手段，实现了环境样 品中茐、苊、　、苯并[a]荧蒽（Ｂ［ａ］Ａ）的同时检测。所建方法对茐、苊、　、Ｂ[a]Ａ的检测限分 别为 ０．０３９，０．０４６，０．０１６和 ０．０４２（ｍｇ／Ｌ）。该法用于大气、海洋沉积物中的茐、苊、　、Ｂ[a] Ａ的同时测定，结果满意。An analytical method has been established for simultaneous determination of fluorene and acenaphthene, chrysene and benz [a] anthracene (B [a] A ) by polarization syn- chronous fluorometry coupled with high performance liquid chromatography (HPLC). The detection limits are: 0.039, 0.046, 0.016 and 0.042 mg/L for fluorene and acenaphthene, chrysene and B[a]A, respectively. The proposed method has been successfully applied to si- multaneous determination of fluorene and acenaphthene, chrysene and B[a]A in environmen- tal air and marine sediment samples.
