The aim of this study was to investigate levels of polychlorinated biphenyls (marker and dioxin-like congeners), polycyclic aromatic hydrocarbons (EPA 15 + 1), polybrominated diphenyl ethers (14 predominant congeners) and pesticides (74 compounds) in various cold-pressed vegetable oils. Poppy seed oil, rapeseed oil, sesame seed oil, pumpkinseed oil, hempseed oil, linaire oil, borage oil and evening star oil were investigated. Results of this study revealed that concentrations of PCBs, PBDEs and PAHs were low in majority of the investigated samples. However, high concentrations of organophosphorus insecticides were found. Chlorpyrifos methyl and pirimiphos methyl were the pesticide residues most commonly found in the studied oils. Concentration of 15 + 1 EPA PAHs was within the 17.85-37.16 μg kg(-1) range, concentration of (marker) PCBs varied from 127 to 24,882 pg g(-1), dioxin-like TEQ values were below 0.1 pg TEQ g(-1). Concentration of PBDEs was below LOQ in most cases.
本研究的目的是调查各种冷榨植物油中多氯联苯（标记物和类二噁英同系物）、多环芳烃（EPA 15 + 1）、多溴二苯醚（14种主要同系物）和农药（74种化合物）的含量。对罂粟籽油、菜籽油、芝麻油、南瓜籽油、大麻籽油、亚麻籽油、琉璃苣油和月见草油进行了调查。本研究结果表明，大多数被调查样品中多氯联苯、多溴二苯醚和多环芳烃的浓度较低。然而，发现了高浓度的有机磷杀虫剂。甲基毒死蜱和甲基嘧啶磷是在所研究的油中最常发现的农药残留。15 + 1 EPA多环芳烃的浓度在17.85 - 37.16 μg kg(-1)范围内，（标记物）多氯联苯的浓度在127至24,882 pg g(-1)之间，类二噁英毒性当量值低于0.1 pg TEQ g(-1)。在大多数情况下，多溴二苯醚的浓度低于检测限。
