This study was aimed to develop mercury database for commonly consumed food by Koreans and assess dietary exposure to mercury among the Korean population linking mercury database with the dietary survey data from Korean National Health and Nutritional Examination Survey (KNHANES). Target foods for mercury database were selected from KNHANES dietary survey data based on 2007‐2009. The mercury contents of foods were collected through the literature review. The developed mercury database covered 50.7% of all kind of foods and 95.1% of food intake as reported by 2007‐2009 KNHANES. The estimated average daily intake of mercury of Korean people was 3.3μg, 0.057µg/kg․bw/day (10% of Provisional Tolerable Weekly Intake (PTWI)), 0.54% of subjects had mercury intake more than PTWI, and 92% of subjects consumed less than 25% of PTWI. Among food groups, fishes and shellfishes was the most dominant source of dietary mercury exposure whose contribution rate was 73.4%. The more people eat fishes and shellfishes, the more mercury exposures per body weight are. The developed mercury database can be used to estimate the dietary exposure to mercury of Korean people, and the method for developing mercury database would help researcher to develop database of other hazardous substances exposed to food.
