Food commodities reflecting in model diet were selected from the KHIDI report and were analysed in cooked or uncooked edible forms using HPLC-Fluorscence Detector. The PAHs dietary intake comparison between home-cooking and dining-out was based on one meal intake suggested in model diet and PAHs dietary intake was estimated by using food consumption rate and body weight of the Korean adult group. The daily PAHs dietary intake was calculated by permutation and combination method with assumption that a person consumed 2 meals from home-cooking menu and 1 meal from dining-out menu. The total PAHs levels in 36 food commodities with samples were ranged from 2.00 ug/kg to ug/kg and a food showing the highest PAHs level was the stir-fried anchovy. The TEQ BaP levels of PAHs were calculated using benzo(a)pyrene equivalents individual congener level and corresponding TEF value and the TEQ BaP level were ranged from 0.03 /kg to 1.31 /kg and a food showing the highest TEQ BaP level was the hamburger. The PAHs dietary intakes per one meal from home-cooking and diningout were /kg/meal and /kg/meal, respectively. This data showed the PAHs dietary intake from dining-out was about 1.7 times higher than from the home-cooking. The daily PAHs dietary intakes of general Korean adult having two meals from home-cooking and one meal from dining-out per a day were ranged between ~ /kg/day and mean value as /kg/day.
