- Ninety-five samples of 18 types of oilseeds used for edible oil production were collected from different origins of China. The occurrence of polycyclic aromatic hydrocarbons (PAHs) in these oilseeds was presented after the analysis by using a simplified gas chromatography–mass spectrometry method. The results indicated that some of these oilseeds were not found of indeno[1,2,3- cd ]pyrene, dibenz[ a,h ]anthracene, and benzo[ ghi ]perylene. Naphthalene and phenanthrene had higher concentration than other individual PAH in the same sample. The range of BaP, PAH4, and PAH16 concentration in these 95 samples was 0.1–14.1, 1.1–74.6, and 81.8–466.8 µg/kg, respectively. LPAH accounted for 87.1–99.5% of the total concentration of PAHs in all of studied oilseeds. The average concentrations of PAH16 in different types of oilseed were different. Meanwhile, the samples collected from different origins of China presented various levels of PAH16. The differences between herbaceous plant oilseeds and woody plant oilseeds in terms of PAH levels were not observed.
