A total of 139 vegetable oils and 48 frying oils produced in China were tested for the levels of 15 Environmental Protection Agency-regulated polycyclic aromatic hydrocarbons (PAHs). The analysis was completed by high-performance liquid chromatography-fluorescence detection (HPLC-FLD). The limit of detection and limit of quantitation were ranged between 0.2-0.3 and 0.6-1 μg/kg, respectively. The average recovery was 58.6-90.6%. The highest mean of total PAHs was found in peanut oil (3.31 μg/kg), while the lowest content was found in olive oil (0.39 μg/kg). In brief, 32.4% of vegetable oils exceeded the European Union maximum levels in China. The detected level of total PAHs in vegetable oils was lower than the frying oils. The mean dietary exposure to PAH15 ranged from 0.197 to 2.051 ng BaPeq/kg bw/day. The margin of exposure values was greater than 10,000, and the cumulative probabilities of the incremental lifetime cancer risk of different age groups were less than the priority risk level (10). Therefore, there was no potential health concern for specific populations.
对中国生产的139种植物油和48种煎炸油进行了15种美国环境保护局规定的多环芳烃（PAHs）含量检测。分析通过高效液相色谱-荧光检测（HPLC-FLD）完成。检测限和定量限分别在0.2 - 0.3和0.6 - 1 μg/kg之间。平均回收率为58.6 - 90.6%。总PAHs的最高平均值在花生油中（3.31 μg/kg），而最低含量在橄榄油中（0.39 μg/kg）。简而言之，在中国32.4%的植物油超过了欧盟的最高限量。植物油中PAHs的检测水平低于煎炸油。PAH15的平均膳食暴露量为0.197至2.051 ng BaPeq/kg体重/天。暴露边际值大于10,000，不同年龄组的终生癌症风险增量的累积概率低于优先风险水平（10）。因此，特定人群不存在潜在健康问题。
