This study was carried out to estimate the daily intake of lead and the relationship among dietary intake, serum level, and urinary excretion of calcium in 30 healthy adults living in rural area of Korea(12 males and 18 females). Analyses for the nutritional status of the subjects were performed by 3-day dietary intake record, duplicated diet collection, 24-hour urine collection, and venous blood sampling. The results were as follows : The mean daily intake of energy was 2, 176.3㎉ and l, 613.9㎉ in males and females of 20∼49years, and l, 914.8㎉ and l, 517.9㎉ in males and females of 50∼59years, respectively. The ratio of carbohydrate: fat: protein was 73.4:13.6:13.0 in males and 76.4:10.3:13.3 in females. The mean daily intake of lead was 277.2㎍ in males and 192.0㎍ in females. The mean daily intake, serum level, and urinary excretion of calcium were 491.1㎎, 8.9㎎/㎗, and 80.7㎎ in males and 426.7㎎, 8.8㎎/㎗, and 80.3㎎ in females, respectively. No significant correlation was found between the daily lead intake and the dietary intake, serum level, and urinary excretion of calcium. It was concluded that the daily lead intake was lower than the acceptable daily lead intake of FAO/WHO but a little higher than that of other investigations. And the daily lead intake was not level that relate to calcium status seriously.
