Abstract: | The levels of 16 US Environmental Protection Agency polycyclic aromatic hydrocarbons (16 EPA PAHs) in Syrian olive oils have been determined. Forty-two samples including commercial extra virgin and virgin olive oils, and virgin olive oils from olive mills were analyzed. Only naphthalene (NAP) was detected in all olive oil samples under investigation. Among the studied 16 EPA PAHs, the highest maximum concentration was also observed for NAP (120 μg kg?1). Moreover, three samples exceeded the European Union (EU) maximum level of 2 μg kg?1 for benzoa]pyrene (BaP) in oils and fats, and only one sample exceeded the EU maximum level of 10 μg kg?1 for the sum of benza]anthracene, chrysene, BaP, and benzob]fluoranthene (PAH4). The likely daily intakes of the total sum of 16 EPA PAHs, the sum of eight genotoxic PAHs, the sum of PAH4, the BaP, and the BaP equivalent through consumption of Syrian olive oils were estimated. |
