Methods] The 5 trace elements were measured in peripheral blood of 2288 children by atomic absorption spectrometer. Resulls] Except for the copper and magnesium ; zinc （36.28%）, calcium （ 57.87% ） and iron （ 5.86% ） were all in deficient status. Concentrations of zinc, calcium, iron in children of 0 - 1 year group were lower than that in children of other groups. Conclusion] The lack of trace elements in peripheral whole blood of children is prevalent; the younger the less.
