目的:了解长沙市儿童血铅水平。方法:采用日本日立公司Z-2700石墨炉原子吸收光谱仪对1755例0～12岁健康体检儿童进行血铅检测。结果:1755名儿童中高铅血症检出率为10.6%,血铅平均值66.6μg/L,其中男童检出率为11.0%,女童检出率为10.2%;城市儿童检出率为8.0%,农村儿童检出率为13.9%,农村明显高于城市,差异有统计学意义(P<0.05);各年龄组中幼儿组高铅血症检出率最高14.2%,学龄前组次之12.5%,学龄组8.4%及婴儿组7.2%检出率相对较低。结论:应加强铅中毒危害知识的宣传教育,尤其应针对农村地区及婴幼儿的家长开展相关健康宣教,预防儿童铅中毒发生。
Objective: To understand the level of blood lead in children in Changsha. Methods: Blood samples were collected from 1755 healthy children aged 0-12 years by Japan Hitachi Z-2700 graphite furnace atomic absorption spectrometer. Results: Among 1755 children, the detection rate of hyperlipidemia was 10.6% and the average blood lead was 66.6μg / L, of which the detection rate was 11.0% for boys and 10.2% for girls; the detection rate for urban children was 8.0 %, The detection rate of rural children was 13.9%, and the rural area was significantly higher than that of the urban areas (P <0.05). The detection rate of hypercholesterolemia was 14.2% 12.5%, 8.4% in the school-age group and 7.2% in the infant group. Conclusion: Publicity and education on the knowledge of lead poisoning should be strengthened. In particular, health education should be conducted for parents in rural areas and infants and young children to prevent lead poisoning in children.
