摘　　要：目的：调查：2006年门诊儿童血铅水平和铅中毒状况。方法：采用钨舟原子吸收光谱法测定5168例0～18岁儿童血铅水平，对各年龄段儿童血铅水平应用SPSS 12．0软件进行分析。结果：不同年龄、不同性别儿童血铅水平存在显著差异，门诊儿童血铅水平为（55．78±1．65）μg/L，男、女童血铅水平分别为（58．88±1．62）μg/L、（52．48±1．66）μg／L。血铅水平≥100μg／L者483例，占9．35％，其中男童350例，检出率10．98％，女童133例，检出率6．72％，两者比较P≤0．05。结论：儿童血铅水平随年龄的增长而增加，男童铅中毒检出率高于女童。Objective： To investigate blood lead levels （BLL） and lead poisoning of outpatients in 2006. Methods： The blood lead levels of 5 168 among 0 - 18 years old children were measured by atomic absorption spectrometry （AAS）, and the data were analyzed by SPSS 12. 0 software. Results： These children showed remarkable differences of BLL according to their age and gender. Mean blood Pb concentration was （55. 78 ±1. 65） μg/L, boys and girls respectively had a blood lead concentration （58. 88 ± 62） μg/L and （52. 48 ± 1. 66） μg/L. 483 children （9. 42% ） had a maximal blood lead concentration ≥100 μg/L, 350 were male with 10. 97% detection rate and 133 were female with 6. 7% detection rate. There was a statistically significant positive bias （P〈0. 05） for the blood lead concentration between the two groups. Conclusion： Children BLL increases with their age, and the detection rate of male children for lead poisoning is higher than that of female ones.
