宝鸡市儿童血铅、血镉含量测定的分析

目的了解宝鸡地区儿童血铅、血镉水平及其影响因素。方法选择2008年4月至2008年9月来宝鸡市中心医院就诊的318名儿童,按年龄分成婴幼儿、学龄前、学龄期3组,采集指血,使用BH2100型多通道原子吸收光谱仪检测血中铅、镉水平。结果318例儿童平均血铅水平52.8μg/L,血镉水平0.616μg/L。不同性别血铅、血镉水平比较差异无统计学意义(P>0.05),不同年龄血铅含量比较差异有统计学意义(P<0.05);而不同年龄血镉含量比较差异无统计学意义(P>0.05)。血铅水平≥100μg/L的儿童有35例,占总调查人数的11.0%。结论宝鸡市儿童血铅水平和铅中毒流行率较高;儿童血镉水平正常,应继续关注本地区儿童血铅、血镉水平的变化。

Analysis of Children's Blood Lead,Blood Cadmium Assay in Baoji City

Objective Understand the level of children＇s blood lead and cadmium, as well as their influencing factors in Baoji. Methods Select 318 children in our hospital from April to September of 2008, deride them into three groups including infant, preschool and school-age, and collect their blood of finger, use multi-channel BH2100 atomic absorption spectrometry to measure the level of lead and cadmium in blood. Results The average level of children＇s blood lead in 318 eases is 52.8μg/L, the average level of blood cadmium is 0. 616μg,/L. There is no obvious difference （P〉0.05） of children blood lead and cadmium level in different sex,there is obvious differenee（P〈0.05） of blood lead content in different age,and no obvious difference （P〉0.05） of cadmium content in different age. Children of blood lead levels ≥100ug/L have 35 cases, about 11.0% in the total investigated number. Conclusion The prevalence of children＇s blood lead level and lead poisoning in baoji city is higher; and the level of children＇s blood cadmium is normal. We should continue to pay attention to children＇s blood lead and cadmium levels in this region.
