目的 :了解太原市幼儿血铅水平及环境铅污染状况。方法 :用原子吸收法在质控条件下测定末稍血铅、空气、土壤及学习用品中铅的含量。结果 :幼儿血铅均值为 (0 .637～ 1 .388) μmol/L(几何均值 0 .498～ 0 .982 μmol/L) ,63 %～ 92 %的幼儿血铅≥ 0 .483μmol/L ,两项皆以电池厂与煤气公司第一幼儿园为最高。 3所幼儿园空气铅超标。土壤铅全部超标 ,也以上述两园为最高。学习用品中浅绿色桌面漆层含铅量为 4 0 94.5μg/g,超标 1 5 .4倍。 结论 :太原市幼儿血铅水平高、超标人数众多 ,应予以重视。土壤已被铅污染 ,可能是幼儿血铅高的主要原因
Objective: To understand the level of lead in children in Taiyuan and environmental lead pollution. Methods: Atomic absorption method was used to determine the content of lead in the final blood lead, air, soil and school supplies under the control of quality control. Results: The average blood lead level in young children was (0.637-1.388) μmol / L (geometric mean 0.498-0.982 μmol / L), and the levels of lead in children were higher than 0.483μmol / L in 63% -92% Both the battery factory and the first kindergarten gas company for the highest. 3 kindergarten air lead exceeded. Soil lead exceeded all of the above, but also the above two parks for the highest. Learning supplies in the light green tabletop lead content of 4 0 94.5μg / g, exceeding the standard 1.54 times. Conclusion: The level of blood lead in Taiyuan infants is too high. The soil has been contaminated with lead, which may be the main cause of high blood lead levels in young children
