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.

The contents of benzo(a)pyrene (Bap.), Pyrene(Py) and Perylene(Pery) were determined by one-dimensional dual band thinlayer chromatogragphy and spectrofluorophotometer in soil samples from road at 36 places of Ulsan and 6 places of Seoul from April to May, 1984. The concents were as follows: 1. Ulsan city : Bap. 0.05-3.66 $\mu$g/g ; mean 1.07 $\mu$g/g Py. 0.60-11.01 $\mu$g/g ; mean 4.34 $\mu$g/g Pery. 0.94-5.48 $\mu$g/g ; mean 1.83 $\mu$g/g 1) Industrial area : Bap. 0.03-3.66 $\mu$g/g ; mean 5.28 $\mu$g/g Py. 2.34-9.07 $\mu$g/g ; mean 5.28 $\mu$g/g Pery. 1.01-3.69 $\mu$g/g ; mean 2.09 $\mu$g/g 2) Commercial area : Bap. 0.15-2.27 $\mu$g/g ; mean 0.29 $\mu$g/g Py. 0.06-11.0 $\mu$g/g ; mean 4.04 $\mu$g/g Pery. 1.03-5.48 $\mu$g/g ; mean 1.84 $\mu$g/g 3) Residential area : Bap. 0.05-0.05 $\mu$g/g ; mean 0.29 $\mu$g/g Py. 1.34-5.53 $\mu$g/g ; mean 2.74 $\mu$g/g Pery. 0.94-2.15 $\mu$g/g ; mean 1.18 $\mu$g/g 2. Commerical area in Seoul : Bap. 0.35-1.01 $\mu$g/g ; mean 0.74 $\mu$g/g Py. 9.37-24,44 $\mu$g/g ; mean 18.64 $\mu$g/g Peay. 1.47-2.24 $\mu$g/g ; mean 1.87 $\mu$g/g 3. The areas that had high contents of Benzo(a)pyrene had also high contents of Pyrene and Perylene. 4. The industrial area had the highest contents of polynuclear aromatic hydrocarbons, followed by commercial area and residential area. 5. The contents of Bap. and Pery. in the commercial area were similar in Seoul and Ulsan, while the content of Py. in Seoul was 4 times higher than in Ulsan.
