This study was carried out to investigate contents of 8 polycyclic aromatic hydrocarbons (PAHs) from frequently consumed seafood and dairy products and to evaluate their chemical analysis methods. Samples were collected from markets of 9 cities in Korea chosen as the population reference and evaluated. The methodology involved saponification, extraction with n-hexane, clean-up on Sep-Pak silica cartridges and gas chromatograph-mass spectrometry analysis. Validation proceeded on 2 matrices. Recoveries for 8 PAHs ranged from 86.87 to 103.57%. The limit of detection (LOD) 8 PAHs was 0.040.20 µg/kg, and limit of quantification (LOQ) of 8 PAHs was 0.120.60 µg/kg. The mean concentration of benzo[a]pyrene (BaP) was 0.34 µg/kg from seafood and 0.34 µg/kg from dairy products. The total PAHs concentration was 1.06 µg/kg in seafood and 1.52 µg/kg in dairy products.
本研究旨在调查常见食用海鲜和乳制品中8种多环芳烃（PAHs）的含量，并评估其化学分析方法。样本从韩国9个城市的市场采集，这些城市被选为总体参考并进行评估。该方法包括皂化、正己烷萃取、Sep-Pak硅胶柱净化和气相色谱-质谱分析。在2种基质上进行了方法验证。8种PAHs的回收率在86.87%至103.57%之间。8种PAHs的检测限（LOD）为0.040.20μg/kg，定量限（LOQ）为0.120.60μg/kg。海鲜中苯并[a]芘（BaP）的平均浓度为0.34μg/kg，乳制品中为0.34μg/kg。海鲜中PAHs的总浓度为1.06μg/kg，乳制品中为1.52μg/kg。
