Abstract:
Seventeen trace elements, including twelve essential trace element, and three normal elements in serum of 417 healthy students aged 7 to 20 in Shanghai were analysed. Except Se which was determined by catalytic pulse polarography, Zn, Cu, Fe, Mn, Cr, Mo, Si, Sn, Ni, V, Co, Cd, Pb, Al, Ti, Sr, Ca, Mg and P in serum were measured by ICP-AES. The result showed that the distribution curve of normal elements and Zn, Cu in serum was more concentrated than the other trace elements. There were significant positive correlation between serum Zn, Fe, Mn, Sr and age, and negative correlation between Cu, Cr, Se, Pb and age, respectively. The elements of males were the same as that of females in total population, but the majority of the elements in serum had sex difference in different age-groups. The serum Cr, Si, Pb contents were higher, and Cu, Fe, Mn, Sr were lower in the urban than in the rural adolescents.
