摘要 目的:探讨电子垃圾拆解区铅暴露对儿童外周血红细胞平均指数的影响。方法:采集143名8-14岁儿童(暴露组70名,对照组73名)肘静脉血2 m L,用石墨炉原子吸收光谱法检测血铅浓度,半自动血细胞分析仪测定红细胞相关指数。结果:暴露组(80.5μg/L)血铅中位数水平高于对照组(73.4μg/L),暴露组血铅中位数水平≥100.0μg/L的占20.0%;暴露组男童红细胞计数(RBC)、血红蛋白(HGB)含量及红细胞比容(HCT)水平均低于同性别对照组(P〈0.05),而红细胞体积分布宽度(RDW)水平高于同性别对照组(P〈0.05);暴露组女童RBC、HGB、HCT及平均红细胞容积(MCV)水平均低于同性别对照组(P〈0.01);MCV、平均HGB和RDW改变与血铅暴露相关。结论:电子垃圾拆解区铅暴露对学龄儿童造血功能有一定影响。
