estimate the daily dietary intake of PCDDs and PCDFs in Korean adults residing in different regions. Subjects
were recruited and divided into three groups according to the districts where they lived: rural (n=213), coastal
(n=193), and urban district (n=187). Subjects were interviewed using a general questionnaire and 24-hour recall
for dietary intake. The daily intake of dioxins was estimated through the use of the database of dioxins contents
in 35 Korean foods. The average age of the subjects were 61.5 years for coastal district, 57.6 years for rural
district, and 49.4 years for urban district. Daily energy intake was 1707.7 kcal for rural district, 1596.5 kcal
for urban district, and 1493.8 kcal for coastal district. There was no significant difference in total food intake
by regions. The intakes from fishes of coastal district, those from cereals, vegetables, meats, and seasonings
of rural district, and those from sugars, pulses, eggs, seaweeds, milks, oils of urban area were higher than
those of the other two districts. The daily dioxins intake of coastal district (0.70 pgTEQ/kg/day) was
significantly higher than those of rural district (0.32 pgTEQ/kg/day) and urban district (0.46 pgTEQ/kg/day).
The dioxins intake from cereals, pulses, vegetables, fishes of coastal district and those from eggs and milks
of urban area were the highest among the districts. The daily dioxins intake was positively correlated with
the intakes of meats, eggs, fishes, oils, and seasonings. Therefore, it could be concluded that the daily dioxins
intake of coastal district is higher than that in other districts and the fish is one of the main sources in dioxin
intakes. However, daily dioxins intakes of the three regions were below the level of tolerable daily intake
(TDI).
