Abstract
This study was carried out to estimate intake level of Pb, Fe, Cu in rural area of Korea(12 males and 18 females). Analyses for the nutritional status of the record, duplicated diet collections, 24-hour urine collections, and venous blood sampling before measuring of blood pressure. The mean age and blood pressure of the subjects were 45.8$\pm$11.1years and 117.5$\pm$22.2/80.8$\pm$15.6mmHe in males, and 41.9$\pm$11.0years, 110.0$\pm$ 11.9/73.9$\pm$8.5mmHg in females, respectively. In respect to both males and females, mean BMI were 22.0$\pm$2.3, 23.1$\pm$3.0, mean Rohrer index were 131.8$\pm$14.8, 142.4$\pm$20.2 and mean skinfold thickness were 12.4$\pm$5.9mm, 25.3$\pm$7.4mm, respectively. The daily mean intakes of Pb, Fe, and Cu estimated for 3 days were 277.2$\pm$111.2$\mu\textrm{g}$/day, 12.7$\mu\textrm{g}$ 7.6mg/day, and 3.0$\pm$1.4mg/day in males and 192.0$\pm$72.4$\mu\textrm{g}$/day, 13.3$\pm$5.8mg/day, and 3.7 $\pm$1.7mg/day in females, respectively. The mean concentrations of serum Pb, Fe, Cu were 11.0$\pm$2.0$\mu\textrm{g}$/dl, 131.1$\pm$42.6$\mu\textrm{g}$/dl, 120.3$\pm$25.7$\mu\textrm{g}$/dl in males and 9.0$\pm$1.2$\mu\textrm{g}$/dl, 112.2$\pm$ 35.9$\mu\textrm{g}$/dl, 117.3$\pm$17.9$\mu\textrm{g}$/dl in females, respectively. The mean levels of Hb and Hct were 15.1$\pm$1.1g/dl, 45.2$\pm$3.3% in males and 13.1$\pm$0.8g/dl, 39.8$\pm$2.6% in females, respectively. The 24-hour urinary excretions of Pb, Fe, Cu were 35.5$\pm$10.0$\mu\textrm{g}$/day, 0.16$\pm$0.12mg/day, 60.12$\pm$0.02$\mu\textrm{g}$/day in males, and 25.3$\pm$11.0$\mu\textrm{g}$/day, 0.24$\pm$0.20mg/day, 70.07$\pm$0.03$\mu\textrm{g}$/day in females, respectively. In conclusion, the Pb intake in self selected diet of this subjects was not in the level that antagonized to Fe and Cu metabolism seriously.
