일부 도시지역 주민들의 혈중 미량금속 농도 분포 = The Concentration Distribution of Several Trace Metals in Whole Blood of Urban Inhabitants

다국어 초록 (Multilingual Abstract)

To have a fundamental knowledge of blood trace metal concentration in an urban population exposed to an artificially polluted environment, 232 healthy adults (122 male and 110 female) with no known possibilities of being exposed to trace metals or compounds, were sampled during the period of Sep. 2001 through Feb. 2002. Blood concentrations of trace metals were measured by Atomic Absorption Spectrophotometer and the following results were obtained. The mean blood concentration of Cu was higher in women[1.71 ㎍/㎖(0.53-5.60 ㎍/㎖)] than in men [1.34 ㎍/㎖ (0.08-4.32 ㎍/㎖)] with a significant statistical difference(P=0.013), The mean blood concentration of Fe was higher in men [503.7 ㎍/㎖(104.7-803.5㎍/㎖)] than in women [394.5㎍/㎖(64.0-855.0 ㎍/㎖)] with a significant statistical difference (P=0.000). The mean blood concentration of Mg was higher in men [48.37 ㎍/㎖(15.30-82.50 ㎍/㎖)] than in women [33.47 ㎍/㎖(20.32-71.16㎍/㎖)] with a significant statistical difference (P=0.000). The mean blood concentration of Zn was higher in women[11.27 ㎍/㎖(5.60-20.65 ㎍/㎖)] than in men[10.51 ㎍/㎖(4.33-19.80㎍/㎖)] with no statistical significance. Each blood trace metal concentration showed a log-normal distribution pattern. and Cu. Fe. Mg and Zn. all of which are known as essential trace metal. had a broad concentration width.
