A simple and fast method for the determination of PAHs in smoked meat samples was described. The QuEChERS (Z-Sep) procedure was used for sample preparation. Gas chromatograph-mass spectrometer with electron ionization (EI) was used to separate and detect the PAHs. All 16 common PAHs were analyzed successfully. Matrix-matched calibration was applied. Spiked samples were performed at 1 ng/g (=10) and 10 ng/g (=10) for two days. Overall recoveries of PAHs were within 74 to 117%, with RSDs within 1.15 to 37.57% and 1 and 10 ng/g wet weight for first and second day, respectively. In most of the analyzed smoked meat samples, there were no exceeded levels compared to the maximum levels declared by Commission Regulation (EU) number 835/2011. The method can be recommended for routine analysis for laboratories having a large number of samples.
描述了一种用于测定烟熏肉样品中多环芳烃的简单快速方法。采用QuEChERS（Z-Sep）方法进行样品前处理。使用带有电子电离（EI）的气相色谱-质谱联用仪分离和检测多环芳烃。成功分析了所有16种常见的多环芳烃。采用基质匹配校准。在两天内分别以1 ng/g（=10）和10 ng/g（=10）的加标量对样品进行加标。多环芳烃的总体回收率在74%至117%之间，第一天和第二天的相对标准偏差分别在1.15%至37.57%之间，加标量分别为1和10 ng/g湿重。在大多数分析的烟熏肉样品中，与欧盟委员会法规（EU）第835/2011号规定的最大限量相比，没有超标情况。该方法可推荐给有大量样品的实验室进行常规分析。
