A multiresidue method was developed for the de termination of 16 polycyclic aromatic hydrocarbons (PAHs) in unifloral and multifloral honeys. The analytical procedure is based on the matrix solid-phase dispersion of honey on a mixture of Florisil and anhydrous sodium sulfate in small glass columns and extraction with hexane-ethyl acetate (90 + 10, v/v) with assisted sonication. The PAH residues are determined by gas chromatography with mass spectrometric detection using selected-ion monitoring. Average recoveries for all the PAHs studied were in the range of almost 80 to 101%, with relative standard deviations of 6 to 15%. The limits of detection ranged from 0.04 to 2.9 microg/kg. The simultaneous extraction and cleanup of samples makes this method simple and rapid, with low consumption of organic solvents
开发了一种多残留方法，用于测定单花蜂蜜和多花蜂蜜中的16种多环芳烃（PAH）。分析程序基于将蜂蜜在小玻璃柱中的弗罗里硅土和无水硫酸钠混合物上进行基质固相分散，并用己烷 - 乙酸乙酯（90 + 10，v/v）辅助超声提取。通过气相色谱 - 质谱检测，采用选择离子监测来测定PAH残留量。所研究的所有PAH的平均回收率在近80%至101%的范围内，相对标准偏差为6%至15%。检测限范围为0.04至2.9微克/千克。样品的同时提取和净化使得该方法简单快速，有机溶剂消耗低。
