In this study, simple GC-MS methods for analysising sixteen PAHs and seven PAEs were individually established. The LOQs for PAHs and PAEs were ranging from 0.18 to 0.42 μg/kg and 0.19 to 1.50 μg/kg, respectively. The recoveries for DD samples were in the range of 84.8-115.5% and 84.2-109.3% for PAHs and PAEs, respectively. Furthermore, PAHs and PAEs concentrations in soybean, rapeseed, corn and rice bran oil distillates were evaluated. PAHs were found in all the DD samples and the concentrations of BaP, PAH4 and total PAHs were 0.89-55.58, 8.11-326.07 and 115.77-966.40 μg/kg, respectively. Correspondingly, total PAEs concentrations ranged from 2.45 to 24.52 mg/kg, and the mean value was 7.76 mg/kg. The results illustrated that the contents of PAHs and PAEs in the DDs were extremely higher than those in the edible oils, thus indicating that specific issues should be considered in the vegetable oil DDs and DD-based products.
本研究分别建立了分析十六种多环芳烃和七种邻苯二甲酸酯的简单 GC-MS 方法。多环芳烃和邻苯二甲酸酯的 LOQs 范围分别为 0.18-0.42μg/kg 和 0.19-1.50μg/kg。DD 样品中多环芳烃和邻苯二甲酸酯的回收率分别在 84.8-115.5%和 84.2-109.3%范围内。此外，还评估了大豆、油菜籽、玉米和米糠油馏分中的多环芳烃和邻苯二甲酸酯浓度。所有 DD 样品中均发现多环芳烃，BaP、PAH4 和总多环芳烃的浓度分别为 0.89-55.58、8.11-326.07 和 115.77-966.40μg/kg。相应地，总邻苯二甲酸酯浓度范围为 2.45-24.52mg/kg，平均值为 7.76mg/kg。结果表明，DD 中多环芳烃和邻苯二甲酸酯的含量远高于食用油脂，因此在植物油 DD 和基于 DD 的产品中应考虑一些具体问题。
