摘要
目的：了解北京市丰台区学龄儿童血铅水平及其影响因素。方法：2012年4～5月采用分层整群随机方法抽取丰台区3所小学三一五年级儿童进行问卷调查并采集血样，采用电感耦合等离子体质谱仪进行血铅测定。结果：265名9～12岁儿童血铅水平为（50．7±24．1）μg／L，铅中毒（血铅含量≥100μg/L）的检出率为45．3％，血铅含量≥100μg/L的检出率为3．4％。多因素Logistic回归分析表明，铅中毒的影响因素可能为居室燃煤取暖、住房附近有铅作业相关工厂。结论：北京市丰台区学龄儿童铅暴露不容忽视，需要政府和社会采取相应措施，为儿童创造一个安全的成长环境。
Objective： To understand the blood lead level and influencing factors among school - age children in Fengtai district of Beijing city.

Results ： The blood lead level of 265 chil- dren aged 9 -12 years old was （50.7 ±24.1）μg/L, the detection rate of lead poisoning （blood lead content ≥100μg/L） was 45.3% , the detection rate of children with blood lead content ≥100μg/L was 3.4%. The results of multivariate logistic regression analysis showed that the influencing factors of lead poisoning might include coal - fired heating, living near a lead operation factory.
