目的：探讨上海市儿童血铅水平及相关危险因素；探讨产业转型后儿童铅含量变化趋势，为上海市环境铅污染治理政策制定提供数据依据。采用分层聚类随机抽样方法。采用钨雾化吸收分光光度计测定血铅水平。上海市0 ~ 6岁儿童血铅的算术平均值、几何平均值和中位数分别为22.49µg/L、19.65µg/L和19.5µg/L，其中浓度≥100µg/L为0.26%(6/2291)，浓度≥50µg/L为2.7%（61/2291）。男孩的水平（23.57µg/L）高于女孩（21.2µg/L）。血铅水平随着年龄的增长而增加。本次调查结果显示，崇明区是最高的，杨浦区是最低的，这一结果与上海之前的调查结果完全相反。铅污染的危险因素包括居住环境、父母受教育程度、社会地位、爱好、儿童营养状况等。上海市儿童血铅水平低于上海市前期和国内已发表的研究数据，但高于发达国家的血铅水平。随着产业转型，城区血铅水平高于中心区。社会和政府应该积极关注城市儿童铅中毒问题。
To determine blood lead levels and to identify related risk factors among children in Shanghai; to explore the lead change trend of children after industrial transformation and to provide data for policy development to control environmental lead pollution in Shanghai. A stratified-clustered-random sampling method was used. A tungsten atomizer absorption spectrophotometer was employed to determine blood lead levels. The arithmetic mean, geometric mean and median of blood lead levels of 0- to 6-year-old children from Shanghai were 22.49 µg/L, 19.65 µg/L and 19.5 µg/L, including 0.26% (6/2291) with concentrations ≥100 µg/L and 2.7% (61/2291) with concentrations ≥50 µg/L. Boys' levels (23.57 µg/L) were greater than those of girls (21.2 µg/L). The blood lead levels increased with age. This survey showed that the Chongming district was the highest and Yangpu district was the lowest, this result is completely opposite with the earlier survey in Shanghai. Risk factors for lead contamination included housing environment, parents' education levels, social status, hobbies, and children's nutritional status. The blood lead levels of children in Shanghai were lower than the earlier data of Shanghai and those of published studies in China, but higher than the blood lead levels of developed countries. The blood lead levels of urban districts are higher than the central districts with the industrial transformation. Society and the government should take an active interest in childhood lead poisoning of urban areas.
