摘　　要：目的了解湛江市区学龄前儿童血铅、锌、铜、钙、铁、血红蛋白的水平.方法对湛江市区 440名3～6岁的儿童进行静脉血铅、锌、铜、钙、铁测定,同时取末梢血测定血红蛋白含量.结果 440名儿童血铅为0.625±0.319 μmol/L,其中铅中毒(血铅值≥0.483 μmol/L)流行率为56.4%.铅中毒儿童的血锌、钙、血红蛋白水平均低于非铅中毒儿童的血锌、钙、血红蛋白水平(P<0.01),而且血钙、血红蛋白水平随着铅中毒的程度加重而逐渐降低;血铜、铁水平在非铅中毒及不同程度的铅中毒儿童中差异无显著性(P均>0.05).结论湛江市区的儿童铅中毒流行率明显高于全国儿童的平均值(29.91%),铅中毒儿童存在缺锌、缺钙及血红蛋白水平下降等状况.Objective To observe the level of blood lead, zinc, iron, calcium, copper and hemoglobin in preschool children of urban area in Zhanjiang.Methods The levels of vein blood lead, zinc, copper, calcium, iron and the content of hemoglobin of 440 children were determined. Results The average level of blood lead among 440 children was 0.625±0.319 μmol/L, the prevailing rate of plumbism was 56.4% according to the level of plumbism ( 0. 483 μmol/L). The levels of blood zinc, calcium, hemoglobin in plumbism children were lower than those in non-plumbism children (P <0. 01). And blood calcium, hemoglobin level were reduced gradually as the degree of the lead poisoning was aggravated. Blood copper, iron level had no difference among all children. Conclusion The prevailing rate of plumbism in children of urban area of Zhanjiang is higher than that in national children, the states of zinc deficiency, calciprivia, and low hemoglobin level exist in plumbism children. 【
