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 $4.78{\mu}g/kg$, and the average was $0.11{\mu}g/kg$. 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 $4.26{\times}10^{-3}ng/kg$ b.w./day for total population group and $7.64{\times}10^{-3}ng/kg$ 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 $7.28{\times}10^7{\sim}1.74{\times}10^8$ and $3.95{\times}10^7{\sim}9.42{\times}10^7$, respectively. Accordingly, the health risk from benzo(a)pyrene caused by the intake of edible oils was considered as a very low level.

식용유지류의 섭취로 인해 발생하는 PAHs의 대표적인 발암물질인 벤조피렌의 안전성을 판단하기 위해 시중에 유통되는 288건의 식용유지제품에 함유된 벤조피렌 함량을 분석한 후 위해성을 평가하였다. 사용된 제품은 옥수수기름, 포도씨유, 올리브유, 들기름, 미강유, 참기름, 콩기름, 해바라기유 등이며 벤조피렌의 검출 범위는 불검출 ${\sim}4.78{\mu}g/kg$이었고 평균 농도는 $0.11{\mu}g/kg$로 나타났다. 국민건강영양조사 5기 2차년도(2011) 자료를 이용하여 전체인구집단과 섭취군의 식용유지류 섭취량을 산출하여 만성 1일 인체노출량을 평가한 결과 식용유지류 섭취로 인한 벤조피렌 노출량은 전체인구집단의 경우 $4.26{\times}10^{-3}ng/kg$ b.w./day, 식용유지류 섭취군의 경우 $7.64{\times}10^{-3}ng/kg$ b.w./day로 나타났다. 인체 위해정도를 파악하기 위해 벤조피렌의 mouse 위상부암에 대한 $BMDL_{10}$값인 0.31~0.74 mg/kg b.w./day와 만성 1일 인체노출량을 이용하여 산출한 MOE 값은 전체인구집단에서는 $7.28{\times}10^7{\sim}1.74{\times}10^8$, 섭취자군에서는 $3.95{\times}10^7{\sim}9.42{\times}10^7$ 수준이었다. 따라서 식용유지류 섭취로 인한 벤조피렌 인체노출의 위해정도는 매우 낮은 것으로 판단된다.
