目的了解合肥市儿童血铅水平现状,为防治铅危害提供依据。方法选择合肥市4个城区,采用随机整群原则对抽取的4个幼儿园1 018名2~7岁儿童进行了毛细血管血铅测定,对所有儿童的个人情况及家庭生活环境均进行了问卷调查。结果合肥市儿童铅中毒率为9.1%;男童血铅平均水平高于女童(t=3.011,P=0.003);男、女童铅中毒率无显著性差异;随年龄增长儿童血铅水平增高(F=7.738,P<0.001);不同年龄儿童铅中毒率差异有显著性(2χ=11.945,P=0.036)。结论合肥市儿童铅中毒发生率较低。但仍需要加强铅防护工作的宣传教育,提高群众的自我保护意识。
Objective To understand the status of blood lead levels in children in Hefei and provide the basis for the prevention and control of lead hazards. Methods Four urban districts of Hefei were selected. Blood lead levels were measured in 1 018 children aged 2 to 7 in 4 kindergartens by random cluster analysis. All children were assessed for their personal circumstances and family living environment by questionnaire . Results The lead poisoning rate of children in Hefei was 9.1%. The average level of blood lead in boys was higher than that in girls (t = 3.011, P = 0.003). There was no significant difference in the rate of lead poisoning among boys and girls. F = 7.738, P <0.001). There was a significant difference in lead poisoning rates among children of different ages (2χ = 11.945, P = 0.036). Conclusion Hefei children lead poisoning incidence is low. However, there is still a need to step up publicity and education on lead protection work and raise people’s awareness of self-protection.
