钼矿区1～7岁儿童血清钙、铁、锌、铅含量分析

Analysis of Serum Level of Calcium,Iron,Zinc,Lead among children in a molybdenum mining area

目的了解陕某钼矿区1～7岁儿童血清钙、铁、锌、铅元素水平。方法采用美国varian Spectr AA/240FS型原子吸收分光光度计对348例1～7岁儿童血清中元素钙(Ca)、铁(Fe)、锌(Zn)、铅(Pb)进行测定并对结果进行统计分析。结果 锌缺乏90例(占25.86%)、铁缺乏16例(占4.60%)、钙缺乏47例(占13.51%)、铅中毒65例(占18.68%)。结论 该矿区1～7岁儿童锌、铁、钙等元素缺乏率较高,铅超标率亦较高。

Objective To understand the serum level of Ca,Fe,Zn and Pb of children aged 1 to 7 at a mining area of Molybdenum in Huayin County,Shanxi Province. Methods Samples of blood serum of 348 preschool children were collected,and the serum level of calcium（Ca）,iron（Fe）,zinc（Zn） and lead（Pb） were tested by atom absorption spectrophotometer（Varian Spectr AA/240FS,made in USA）. Results The proportion of microelement deficiency for zinc,iron and calcium were 25.86%,4.6%,and 13.51% respectively.Serum level of lead in 65 children（18.68 %） exceeded the poisoning level. Conclusion There were significant deficiency in Zn,Fe and Ca among children in the mining area of Molybdenum in Huayin County,and lead poisoning was also a serious problem.
