摘要
目的探讨铅中毒儿童体内锌、铜、铁、钙等元素含量变化。方法采用分层随机抽样方法进行抽样。在市区、农村、海岛共抽取540名儿童。对这些儿童进行血铅及其他元素(锌、铜、铁、钙等)含量测定,并分析这些元素含量在儿童铅中毒情况下有无变化。结果铅中毒组血锌水平(4.93±1.12)mg/L,明显低于非铅中毒组(t=2.282 P<0.05),其他元素含量两组无差异。多元逐步回归分析结果显示儿童体内血锌、血铜含量对儿童血铅水平有显著意义。结论补充适量锌制剂或通过膳食补锌可预防儿童铅中毒,减少铅对机体的毒性作用。
Objective To discuss the variety of blood zinc,copper,iron,calcium level in children of lead poisoning Methods The stratified - random sampling method was used. Five hundred and forty children were selected in the urban areas, the rural areas and the islands. We examined blood lead level and other elements levels of these children, and analyzed the changes of these elements levels on condition of lead poisoning. Results The blood zinc level of children with lead poisoning was (4. 93 ± 1 12) mg/L, it was significantly lower than that of children without lead poisoning( t = 2.282 P < 0 05). The contents of other elements were no differences between two groups. The results of multiple stepwise regression analysis showed that blood zinc level,blood copper level had statistical significance to the blood lead level. Conclusion To supply proper zinc by preparation or meal can prevent children from lead poisoning, and to reduce the toxicity of lead.
