EXTRACTION AND ESTIMATION OF SOME POLYCYCLIC AROMATIC HYDROCARBONS FROM SOME VEGETABLE OILS

This study was conducted for the purpose of extracting and estimating some PAHs of six vegetable oils selected They (ginger, cloves, bitter almonds, castor, mint and sesame) are used locally for medical, skin and skin treatments. High-performance liquid chromatography (HPLC) technique is used to estimate these PAHs in the vegetable oil samples under study and the standard solution for calculating the retention time for each compound and to identify the area of each peak for vegetable oil samples and the standard solution. The results showed that the concentrations of vegetable oil samples, calculated according to the time of detention between the sample and the standard solution, showed only two compounds, acenaphthylene, Benzo (g, h, i) perylene, with bitter almond oil and sesame oil. While the rest of the compounds did not appear in all study samples, the concentrations are very low and this indicates that these vegetable oils are free from the risk of PAHs. Most of the PHAs compounds were not included in all study samples except acenaphthylene and Benzo (g, h, i) perylene compounds in almond oil and sesame oil but with very few concentrations are not dangers to human health.
