目的:了解血铅水平对儿童智能发育的影响。方法:对儿童保健门诊的1043例3岁以下儿童,用0~6岁儿童神经心理量表进行智能发育水平的测试和原子吸收光谱仪测定血铅。结果:1043例儿童血铅水平最低26μg/L,最高239μg/L,平均(66.77±34.68)μg/L。其中铅中毒174例,铅中毒率为16.68%,铅中毒组儿童智能发育明显低于正常组。结论:儿童智能发育程度与血铅水平密切相关,应开展有效的健康教育和铅污染环境的干预。
Objective: To understand the impact of blood lead levels on the intellectual development of children. Methods: A total of 1043 children under 3 years of age undergoing child health clinics were tested for neurodevelopment by using the neuropsychological scale of children aged 0 ~ 6 years and blood lead level by atomic absorption spectrometry. Results: The blood lead level of the 1043 children was the lowest 26μg / L, the highest 239μg / L, the average (66.77 ± 34.68) μg / L. Among them, 174 cases of lead poisoning and 16.68% of lead poisoning were observed in children with lead poisoning. The intelligence development of children with lead poisoning was significantly lower than that of normal group. Conclusion: The level of intelligence development in children is closely related to the level of blood lead. Effective health education and environmental intervention with lead should be carried out.
