Analysis and Risk Assessment of Benzo(a)pyrene in Edible Oils

Abstract

To assess the health risk for benzo(a)pyrene by the intake of edible oils, 288 cases of edible oils collected from food markets were analysed using the high performance liquid chromatography with fluorescence detector. The levels of benzo(a)pyrene were from non-detection to 4.78 µg/kg, and the average was 0.11 µg/kg. The chronic daily exposures of benzo(a)pyrene for total population group and consumer-only group were estimated using the food consumption data in the fifth Korea National Health and Nutrition Examination Survey in 2011. The estimated daily intake of benzo(a)pyrene was 4.26 × 10 −3 ng/kg b.w./day for total population group and 7.64 × 10 −3 ng/kg b.w./day for consumer-only group. The MOE (margin of exposure) of benzo(a)pyrene for total population group and consumer-only group was 7.28 × 10 7~1 .74 × 10 8 and 3.95 × 10 7~9 .42 × 10 7 , respectively. Accordingly, the health risk from benzo(a)pyrene caused by the intake of edible oils was considered as a very low level.

“…Their results indicated a widespread PAH contamination among the samples. Jang et al [16] estimated the chronic daily exposure to BaP for the total population group and the consumer-only group using food consumption data from the fifth Korean National Health and Nutrition Examination Survey in 2011.
