: 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.
