开发了一种灵敏且选择性的 GC-MS 方法，用于同时分析 2013 年加拿大总饮食研究的食品样品中己二酸二（2-乙基己基）酯 (DEHA) 和 20 种选定的邻苯二甲酸盐。在分析的 159 种不同食品复合样品中，有 141 种至少检测到了 21 种目标化学物质中的一种。然而，在 21 种目标化学物质中，仅检测到 7 种，其中邻苯二甲酸二(2-乙基己基)酯 (DEHP) 和 DEHA 的检测频率最高，分别在 111 种和 91 种不同的食品复合材料样本中检测到，其次是邻苯二甲酸二正丁酯 (DBP) (n = 44)、邻苯二甲酸正丁苄酯 (BBzP) (32)、邻苯二甲酸二异丁酯 (DiBP) (27)、邻苯二甲酸酯 (DEP) (3) 和邻苯二甲酸二环己酯 (DCHP) (1)。 DEP（邻苯二甲酸二乙酯）、DiBP、DBP、BBzP和DCHP的水平总体较低，平均浓度分别为9.63、8.26、23.2、12.4和64.9ngg(-1)。 DEHA和DEHP的含量差异很大，分别为1.4至6010ngg(-1)和14.4至714ngg(-1)。主要在复合材料样品中发现高含量的 DEHA，其中用于制备复合材料的各个食品可能用聚氯乙烯 (PVC) 包装膜包装，而蔬菜和水果样品中发现了最高的 DEHP 含量。
A sensitive and selective GC-MS method was developed and used for simultaneous analysis of di-(2-ethylhexyl) adipate (DEHA) and 20 selected phthalates in the food samples from the 2013 Canadian Total Diet Study. At least one of the 21 target chemicals was detected in 141 of the 159 different food composite samples analysed. However, only seven of the 21 target chemicals were detected, with di-(2-ethylhexyl) phthalate (DEHP) and DEHA being detected most frequently, in 111 and 91 different food composite samples, respectively, followed by di-n-butyl phthalate (DBP) (n = 44), n-butyl benzyl phthalate (BBzP) (32), di-iso-butyl phthalate (DiBP) (27), di-ethyl phthalate (DEP) (3), and di-cyclohexyl phthalate (DCHP) (1). Levels of DEP (di-ethyl phthalate), DiBP, DBP, BBzP and DCHP were low, in general, with average concentrations of 9.63, 8.26, 23.2, 12.4 and 64.9ngg(-1), respectively. Levels of DEHA and DEHP varied widely, ranging from 1.4 to 6010ngg(-1) and from 14.4 to 714ngg(-1), respectively. High levels of DEHA were found mainly in the composite samples where the individual food items used to prepare the composite were likely packaged in polyvinyl chloride (PVC) wrapping film, while the highest DEHP levels were found in the vegetable and fruit samples.
