摘要：Objectives: This survey was designed to conduct the first nationwide dietary exposure assessment on hazardous substances including the intakes of functional food and herbal medicine. In this paper,we introduced the survey design and the results of the dietary exposure status and internal exposure levels of lead (Pb),cadmium (Cd),and mercury (Hg). Methods: We selected 4867 subjects of all ages throughout Korea. We conducted a food survey,dietary survey,biomonitoring,and health survey. Results: Pb and Cd were the highest (median value) in the seaweed (94.2 μg/kg for Pb;594 μg/kg for Cd),and Hg was the highest in the fish (46.4 μg/kg). The dietary exposure level (median value) of Pb was 0.14 μg/kg body weight (bw)/d,0.18 μg/kg bw/d for Cd,and 0.07 μg/kg bw/d for Hg. Those with a blood Pb level of less than 5.00 μg/dL (US Centers for Disease Control and Prevention,reference value for those 1 to 5 years of age) were 99.0% of all the subjects. Those with a blood Cd level with less than 0.30 μg/L (German Federal Environmental Agency,reference value for non-smoking children) were 24.5%. For those with a blood Hg level with less than 5.00 μg/L (human biomonitoring I,references value for children and adults,German Federal Environmental Agency) was 81.0 % of all the subjects. Conclusions: The main dietary exposure of heavy metals occurs through food consumed in a large quantity and high frequency. The blood Hg level and dietary exposure level of Hg were both higher than those in the European Union.
