【摘要】 目的：探讨我市儿童铅中毒状况及血铅水平与钙、铁、锌、之间的相互关系。方法对480名儿童进行血铅、钙、铁、锌测定，将铅中毒组218人(血铅≥100ug/l)血钙、铁、锌缺乏的比例与非铅中毒组262人(血铅≤100ug/l)血钙、铁、锌缺乏的比例进行相互对比分析。结果①儿童铅中毒发病率达45.4%。②铅中毒组缺钙、缺锌发病率较高，与对照组比较差异性有统计学意义(c2＝19.51，P0.05)。结论儿童铅中毒可影响血锌、血钙的吸收。

    Investigate of correlation between blood levels of Pb and Ca,Fe,Zn in children

    Abstract Objective To investigate the current status of lead poisoning of children and the correlation between the level of Pb and that of Ca, Fe, Zn in blood . Methods The level of each element of Pb, Ca, Fe, Zn in blood were measured and analysed for each of the 480 children. Results The lead poisoning of children was 45.4%. In comparison with the contrast group, the lead poisoning group has remarkable difference of decrease in blood levels of Ca and Zn. Conclusion Lead poisoning may cause decrease in blood levels of Zn and Ca in blood.
