Abstract

This study developed a new method for analysing 6-ClBaP and 7-ClBaA in six oil samples using liquid-liquid extraction and solid-phase extraction followed by GC-QQQ-MS. The recoveries of 6-ClBaP and 7-ClBaA were 44.26 ± 2.81% and 92.61 ± 4.09%, respectively. Both the instrument and method LODs were lower than 0.2 μg kg^-1, while the intra-day and inter-day RSD were less than 5%. Five waste frying oils and one peanut oil were tested with the validated determination method. The concentrations of 6-ClBaP and 7-ClBaA in the tested samples ranged from no detection to 0.29 μg kg^-1 and no detection to 0.20 μg kg^-1, respectively. The data of 6-ClBaP and 7-ClBaA detected in this study suggest that a large scale of investigation on Cl-PAHs in foods is necessary.
