本研究的目的是确定无锡市1- 5岁儿童的平均血铅水平和血铅水平升高的患病率。1997年10月至12月对1117名1-5岁儿童进行了毛细血管血铅测定。无锡市1-5岁儿童血铅水平的几何平均值为8.2 pg/dL（0.40 pmol/L）; 27.3%的儿童血铅水平大于或等于10 pg/dL，1.0%的儿童血铅水平大于或等于20 μ g/dL。男性和生活在工业区的人，尤其是北塘、马山和新区的血铅水平明显较高。居住在这些地区和郊区工业区也增加了血铅水平升高的可能性，比值比范围为2.59至4.53。总之，无锡市儿童血铅水平很高，值得关注，特别是在工业区。需要进一步的研究来更好地确定中国儿童铅暴露的程度。此外，血铅采集和测量方法应在中国应用国家标准。(C)北京：科学出版社.
The objective of this study was to determine mean blood lead levels and prevalence of elevated blood lead levels among 1- to 5-year-old children in Wuxi City, China. By use of a representative cross-sectional survey that included measurements of capillary blood lead, 1117 children aged 1-5 years were examined from October through December, 1997. The geometric mean blood lead level for children 1-5 years of age in Wuxi City was 8.2 pg/dL (0.40 pmol/L); 27.3% had blood lead levels greater than or equal to 10 pg/dL and 1.0% had blood lead levels greater than or equal to 20 mug/dL. Blood lead levels were significantly higher for males and for those living in industrial areas, particularly the Beitang, Mashan, and Xinqu districts. Residence in these districts and in the Jiaoqu industrialized district also increased the likelihood of an elevated blood lead level, with odds ratios ranging from 2.59 to 4.53. In conclusion, blood lead levels among Wuxi City children are high enough to be of concern, particularly in industrial areas. Further studies are needed to better define the extent of lead exposure among children in China. In addition, national standards for blood lead collection and measurement methods should be applied in China. (C) 2001 Academic Press.
