摘要
目的探讨儿童血铅水平与钙、铁、锌的相互关系。方法采用钨舟法和火焰法,分别测定我院门诊1688名患儿的血铅和钙、铁、锌水平。结果1688名儿童中,平均血铅水平为48.35μg/L,铅中毒发生率为15.9%,统计分析显示,不同性别之间血铅、钙、铁、锌含量无显著性差异(P>0.05),儿童血铅与钙、锌水平差异有显著性(P<0.05),呈负相关关系。结论儿童铅中毒可导致血钙、锌水平下降。
Objective To investigate the correlation between calcium, iron, zinc and blood levels of lead. Methods A total Of 1,688 children aged 0-6 years old were selected from outpatient department. By using atomic absorption spectrophotometry, the blood levels of lead, calcium, iron, and zinc were measured and analyzed. . Results The mean blood lead level was 48. 35μg/L. The prevalence of lead poisoning was 15.9%. Regression and correlation analysis showed that there was significant difference between the blood lead level and calcium or zinc, and the blood lead level was negatively related to calcium or zinc. Conclusion Lead poisoning is associated with decreased blood levels of calcium and zinc.
