摘　　要：[目的]调查丹阳市3-6岁儿童血铅水平，并分析其相关因素，为科学预防提供依据。[方法]在位于不同区域的5所幼儿园，随机抽取316名儿童采集静脉血，采用石墨炉原子吸收光谱法测定血铅；采用SPSS软件统计分析。[结果]儿童血铅总体均值为（0．388±0．158）μmol／L，≥0．483μmol／L的占24．7％，其中丹化幼儿园有47．5％的儿童血铅≥0．483μmol／L。5所幼儿园儿童血铅均值差异有显著性，分别为（0．426±0．150）、（0．277±0．102）、（0．337±0．088）、（0．435±0．168）、（0．451±0．189）μmol／L．F=13．96，P〈0．01。男童血铅均值为0．413μmol／L，较女童的0．363μmol/L高（t=2．11，P=0．034）。[结论]丹阳市儿童血铅均值在全国处于中等水平，居住在工业区、市中心和交通干道的儿童血铅较其他地区高。[ Objective ] To investigate the blood lead level of 3-6 years old children and influence factors of lead in DanYang, for providing evidence of prevention. [ Methods ] 316 blood samples from children in 5 kindergartens （ located in different areas ） in DanYang were collected. GFAAS were used to determine blood lead level. Data were analyzed by SPSS software. [ Results ] Mean blood lead level was 0.388 ± 0.158 μmol/L among 3-6 years old children in DanYang. The blood lead level of 24.7% children was equal or more than 0.483 μmol/L The blood lead level of 47.5% children in DanHua kindergarten was equal or more than 0.483 μmol/L. Mean blood lead level of children in 5 kindergartens was 0.451 μmol/L -0.277 μmol/L respectively with statistical significance（ 0.426 ± 0.150 μmol/L, 0.277 ± 0.102 μmol/L, 0.337 ± 0.088 μmol/L, 0.435 ± 0.168 μmol/L, 0.451 ± 0.189 μmol/L ）. Mean blood lead level of boys （ 0.413 μmol/L ） was higher than that of girls （ 0.363 μmol/L ）. [ Conclusion ] Mean blood lead level of children in DanYang was in the middle level in China.
