Hair samples of 655 children (3-6 yr of age) from metropolitan andsmall cities in Korea were analyzed to determine the content of 23 minorand trace elements with the aim of assessing reference values. Fifteenessential elements (Fe, Zn, Cu, Ca, Mg, Mn, P, Na, K, Cr, Se, Li, V, Co, Mo)and 8 harmful elements (Pb, Al, Hg, As, Cd, Ba, Bi, U) were taken intoaccount. Measurements were performed by inductively coupledplasma-mass spectrometry. The overall mean values were as follows(μ/g): Al, 8.78; As, 0.11; Ba, 0.32; Bi, 0.04; Ca, 212.47; Cd, 0.08; Co, 0.01; Cr,0.47; Cu, 15.51; Fe, 12.62; Hg, 0.49; K, 34.10; Li, 0.01; Mg, 12.29; Mn, 0.29;Mo, 0.07; Na; 27.14; P, 121.21; Pb, 1.68; Se, 0.75; U, 0.04; V, 0.08; Zn, 69.99.There was no significant difference in hair mineral content between childrenliving in metropolitan and small cities. There were positive correlationsbetween age and the level of Zn, Ca, Na, P, Mn, and Li, but negativecorrelations between age and the level of Cr, V, and U. The proposed referencevalues for hair Zn, Mg, Ca, As, and Cd of Korean children werelower than those of other countries, but the values for other elements ofhair were not significantly different from those of other countries.
