Survey Analysis on Blood Lead Level of Children in Jinchang City of Gansu Province
【摘要】 目的了解甘肃省金昌市2~7岁儿童血铅水平。方法随机抽取2004年10月~2005年6月金昌市部分幼儿园256名儿童。男133名,女123名;用石墨炉原子吸收分光光度仪测定血铅水平。结果儿童血铅水平为(126.30±52.98)μg/L。血铅水平最低值为28.3μg/L,最高值为268.0μg/L,超过100μg/L者160例,占62.54%。血铅水平随年龄增加有上升趋势,2~3岁组明显低于5~6岁组、6~7岁组,差异有统计学意义(P<0.05,0.01);性别间血铅水平差异无统计学意义(P>0.05)。结论甘肃金昌市儿童血铅水平较高,铅中毒现象不容忽视。
