Objectives : Arsenic (As) is ubiquitously distributed in the environment and has been known as a human carcinogen. The main source of arsenic exposure in general population is an oral route through As-contaminated water and foods. This study was performed to estimate the daily intake of As from diet and associated factors in Korean adults. Methods : We investigated 590 adults, 249 males and 341 females, with age of 20 years and older, who had not been exposed to the As occupationally. Study subjects were interviewed for demographic characteristics, lifestyles and diets during the last 24 hours. The estimation of As intake daily was based on amount of food consumption and As concentration in each food by using database of As concentrations in 117 food species. Results : Daily As intake was estimated as 56.46 ㎍/day, 56.60 ㎍/day in male and 56.36 ㎍/day in female. As intake was not significant from sex, age group, smoking and alcoholic habits, while was by occupation with the most intake of As in fishery. The daily As intakes was positively correlated with the total food consumption, specifically related with fishes and shellfishes, seaweeds, oils, grains and flavors. About 75% of As intake from diet was contributed by seafoods, such as 32.07 ㎍/day from fishes & shellfishes and 10.05 ㎍/day from seaweeds. However, it is necessary to evaluate if the dietary As intake affects on the levels of As in the body. Conclusions : The amount of As intake daily in Korean adults was estimated as 56.46 ㎍/day, and is determined mainly by diet behavior. The seafoods, such as fishes & shellfishes and seaweeds, is major source of As exposure from diet in Korean.

본 연구에서는 식생활 양상이 서로 다를 것으로 생각되는 어촌, 농촌, 도시 지역별 각각 213명, 193명, 187명을 대상으로 직접면담과 24시간 회상법에 의한 식사섭취조사를 실시한 후 35가지 식품 중 다이옥신 함량 자료를 이용하여 추정한 다이옥신 섭취상태를 비교·평가하였다. 지역별 조사대상자의 평균 연령은 어촌 61.5세, 농촌 57.6세, 도시 49.4세순으로 유의하게 높았으며, 신장은 도시 대상자가 160.0 ㎝로 어촌의 158.1 ㎝나 농촌의 157.7 ㎝보다 유의하게 높았다. 지역별 남녀 성별 분포는 유의한 차이가 없었다. 1일 에너지 섭취량은 농촌 1707.7 ㎉, 도시 1596.5 ㎉, 어촌 1493.8 ㎉로 농촌이 어촌보다 유의하게 높았다. 1일 총 식품섭취량은 지역별 유의한 차이가 없었으나 어패류는 어촌지역이, 곡류, 채소류, 육류, 조미료류는 농촌지역이, 당류, 두류, 난류, 해조류, 우유류, 유지류는 도시지역이 가장 높았다. 35종 식품의 다이옥신 함량자료를 이용하여 평가한 어촌, 농촌, 도시 대상자의 1일 다이옥신 섭취량은 어촌이 0.70 pgTEQ/㎏/day로 농촌의 0.32 pgTEQ/㎏/day나 도시의 0.46 pgTEQ/㎏/day보다 유의하게 높았다. 곡류, 두류, 채소류, 어패류를 통한 다이옥신 섭취량은 어촌이, 난류와 우유류를 통한 다이옥신 섭취량은 도시가 가장 높았다. 전체 대상자의 다이옥신 섭취량은 육류, 난류, 어패류, 유지류, 조미료류 및 총 식품섭취량과 각각 유의한 정의 상관관계를 보였다. 이상의 연구결과를 종합할 때 식품을 통한 다이옥신 섭취량은 어촌 지역이 농촌이나 도시보다 높고 어패류나 동물성식품을 통한 섭취가 높았으나, 세 지역 모두 우리나라 내용(耐容) 1일 섭취량보다 낮아 안전한 수준이었다. The human population is mainly exposed to dioxins through the diet. The purpose of this study was to 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 ㎉ for rural district, 1596.5 ㎉ for urban district, and 1493.8 ㎉ 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/㎏/day) was significantly higher than those of rural district (0.32 pgTEQ/㎏/day) and urban district (0.46 pgTEQ/㎏/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).
