    【摘要】目的：探讨儿童必需元素与毒性元素血铅水平的关系。方法：应用原子吸收法检测必需元素铜、锌、钙、镁、铁含量，阳极溶出伏安法检测毒性元素血铅含量，并与正常对照组进行比较分析。结果：血铅偏高组，各年龄段儿童锌、铁、钙必需元素的含量偏低，差异有显著性，铜、镁含量差异无显著性。结论：儿童血铅水平升高是引起儿童必需元素锌、钙、铁吸收减少的重要因素。

    【Abstract】Objectivel: Discusses the child essential element and the toxic element blood lead level relations. Method: Using the atomic absorption law examination essential element copper, the zinc, the calcium, the magnesium, the hard content, the anode dissolves the voltammetry examination toxic element blood lead content, and carries on the comparative analysis with the normal comparison group.Finally: The blood lead high group, various ages section child zinc, hard, the calcium essential element content is somewhat low, the difference has apparent nature, copper, the magnesium content difference does not have apparent nature. Conclusion: The child blood lead level elevates causes the important attribute which the child essential element zinc, the calcium, the hard absorption reduces. ......
