This study was performed to propose a new life style to reduce or simply eliminate dioxin exposure levels in high school students using known statistical data. In order to do that, the analytical results of dioxin concentrations in food and the environment were collected by KFDA and NIER. Additionally, a questionnaire (male=73, female=58) for students about dietary intake has been surveyed and the dioxin exposure levels in the students’ environments estimated. The dioxin intake amount has been estimated by using the questionnaire results of n=131. The average dietary intake of PCDD/Fs through food consumption and the environment (air and soil; detection in water has not been assumed) in Korea was estimated to be 0.530 pg-TEQ/kg body weight/day. The dietary intake of PCDD/Fs for the male and female Korean high school students has been calculated to be 0.526 and 0.536 pg TEQ/kg body weight/day, respectively. As a result of comparing dietary intakes with the tolerable daily intake of 4 pg TEQ/kg bw/day, the mean dioxin exposure levels for Korean high school students were 8 times lower than the present TDI level proposed by the KFDA. In this study, the dietary intake of dioxin has been estimated to account for 87 percent of human exposure. Especially following food types contributed to dioxin intake in decreasing order: fish (40%) > egg (21%) > milk & milk products (11%) > beef & pork (10%). This result is similar to those reported in other studies in Korea (KFDA, 2006~2009).
