21347名儿童血铅水平的分析

Analysis on blood lead levels of 21 347 children

目的：分析0-14岁儿童血铅水平,进一步为行政部门采取预防儿童铅中毒的综合干预措施提供依据。方法：采用日立公司Z-2700石墨炉吸收光谱仪对21 347名0-14岁健康体检儿童进行血铅检测,血铅水平≥100μg/L定义为铅中毒。结果：本次体检的21 347名儿童中,平均血铅水平为（68.22±31.79）μg/L,铅中毒检出率为9.63%,血铅水平均数和铅中毒率男童明显高于女童,差异有统计学意义（P〈0.01）。0-5岁男童血铅水平均数呈现逐渐增加的趋势,不同年龄组儿童血铅水平差异有统计学意义（P〈0.01）。结论：铅中毒依然是影响儿童健康的重要公共卫生问题,政府行政部门应该进一步采取综合干预措施预防儿童铅中毒。

Objective： To analyze the blood lead levels of 0-14- year- old children,further provide a basis for administrative departments to take comprehensive interventional measures to prevent lead poisoning in children. Methods： Atomic absorption spectrometer was used to detect the blood lead levels of 21 347 children aged 0- 14 years old when they received physical examination in the hospital,blood lead level≥100 μg /L was designed as lead poisoning. Results： The average blood lead level was（ 68. 22 ± 31. 79） μg /L,the detection rate of lead poisoning was 9. 63%,the average blood lead level and the detection rate of lead poisoning in boys were statistically significantly higher than those in girls（ P〈0. 01）. The average blood lead level of boys aged 0- 5 years old showed gradual increasing trend,there was statistically significant difference in blood lead level among children in different age groups（ P〈0. 01）. Conclusion： Lead poisoning is still one of the important public health problems affecting childhood health,the government should take comprehensive intervention measures to prevent lead poisoning in children.
