Edible oils such as palm, corn and sunflower oils were analyzed for the presence of light and heavy polycyclic aromatic hydrocarbons (PAHs) using liquid-liquid extraction, clean-up on a silica gel column, and determination by High Performance Liquid Chromatography (HPLC) using a fluorescene detector. In this study, 15 PAHs compounds induding Napthalene, Acenapthene, Fluorene, Phenanthrene, Anthracene, Fluoranthene, Pyrene, Benzo[a]anthracene, Chrysene, Benzo[b]fluoranthene, Benzo[k]fluoranthene, Benzo[a]pyrene, Dibenz[a,h]anthracene, Benzo[g,h,i]perylene and Ideno[1,2,3-cd]pyrene were studied. The linearity of the method was between 0.9996 to 1.0000. Limit of detection (LOD) was ranged from 0.01 to 1.17 ng/g, whereas limit of quantification (LOQ) was ranged from 0.02 to 3.51 ng/g. All PAHs were separated and analyzed in 31 minutes. Com oil sample did not show any concentration of Benzo[a]anthracene, Chrysene, Benzo[a]pyrene and Benzo[b]fluoranthene (PAH4), whereas palm oil and sunflower oil samples have exceeded the sum of four PAHs (PAH4) limit (10 ng/g), 100.35 ng/g and 116.76 ng/g respectively. Therefore, more studies need to be conduded to confirm this result due to limitation of the study.
