食用油如椰子、花生、氢化蔬菜、亚麻籽、芥末、橄榄、棕榈、精制蔬菜、米糠、红花、芝麻、大豆和向日葵，通过液-液萃取、硅胶柱净化、使用荧光检测器的HPLC分离和测定，分析其是否存在轻和重多环芳烃（PAH）残留物。监测了10种多环芳烃，即苊、蒽、苯并（a）芘、苯并（e）芘、苯并（ghi）芘、苯并（ghi）对296个油样的分析表明，88.5%（262）的样品被不同的PAH污染。在262个受污染的食用油样品中，66.4%的样品显示PAH含量超过德国脂肪科学学会推荐的25 μg/kg。初榨橄榄油中PAH总含量最高（624 μg/kg），精炼植物油中最低（40.2 μg/kg）。橄榄油中重质多环芳烃含量最高（265 μg/kg），米糠油中最低（4.6 μg/kg）。菲存在于58.3%的油样分析，其次是蒽（53%）。在重度PAH中，苯并（e）芘在31.2%的样品中观察到，其次是苯并（a）芘（25.5%）。多环芳烃的摄入量最高的是橄榄油（20.8 μg/天），其次是大豆油（5.0 μg/天），最低的是精制植物油（1.3 μg/天）。根据这些监测研究，可以制定多环芳烃允许水平的国际和国家准则，以限制这些有毒污染物的摄入。
Edible oils such as coconut, groundnut, hydrogenated vegetable, linseed, mustard, olive, palm, refined vegetable, rice bran, safflower, sesame, soybean, and sunflower were analyzed for the presence of light and heavy polycyclic aromatic hydrocarbon (PAH) residues using liquid‐liquid extraction, cleanup on a silica gel column, and resolution and determination by HPLC using a fluorescence detector. Ten PAH viz. acenaphthene, anthracene, benzo(a)pyrene, benzo(e)pyrene, benz(ghi)perylene, chrysene, coronene, cyclopenta(def)phenanthrene, phenanthrene, and pyrene were monitored. Analysis of 296 oil samples showed that 88.5% (262) samples were contaminated with different PAH. Of 262 contaminated edible oil samples, 66.4% of the samples showed PAH content of more than the 25 μg/kg recommended by the German Society for Fat Science. The total PAH content was highest in virgin olive oil (624 μg/kg) and lowest in refined vegetable oils (40.2 μg/kg). The maximum content (265 μg/kg) of heavy PAH was found in olive oil and the minimum (4.6 μg/kg) in rice bran oil. Phenanthrene was present in 58.3% of the oil samples analyzed, followed by anthracene (53%). Among the heavy PAH, benzo(e)pyrene was observed in 31.2% of the samples followed by benzo(a)pyrene (25.5%). The intake of PAH was highest through olive oil (20.8 μg/day) followed by soybean oil (5.0 μg/day) and lowest through refined vegetable oil (1.3 μg/day). Based on these monitoring studies, international and national guidelines for permissible levels of PAH can be prepared so as to restrict the intake of these toxic contaminants.
