微量元素与健康研究

目的:探讨该地区儿童血铅增高的原因和血铅增高对儿童的危害性及预防措施。方法:近几年门诊儿童1500例血铅化验,由西安市微量元素检验所提供帮助,1500例均采集静脉血液检测铅含量。结果:在1500例化验的儿童中血铅大于或等于100μg/L共566例;超标率达37.7%,其中男童362例血铅超标,超标率达24.1%;女童204例超标,超标率13.6%;而且年幼儿血铅超标较年长儿低。结论:铅超标的儿童中大部分都存在不同程度的微量元素缺乏,例如:锌、铁、钙、硒,而且与年龄、性别、家庭、环境、生活习惯、喂养习惯、疾病等因素有关,高铅儿童都存在不同程度的各种临床表现。高铅已经严重影响了儿童的生长发育,应予以重视。

Purpose: This paper discusses the root cause of blood Pb exceeding,critical effect and preventive actions.Method: Based on the assay result of 1500 samples from clinic infants,with the help of Trace Elements Study Bureau of Xi'an City and all samples are vein blood.Result: there are 566 samples' blood Pb no less than 100 μg/L.In the other word,it's 37.7% over standard.Among them,there are 362 samples from boy with 24.1%;204 samples from girl with 13.6%.Moreover,the older,the higher of blood Pb.Conclusion: most of these infants are also short of trace elements more or less,such as Zn,Fe,Ca,Se.Furthermore,The high blood Pb is also related with the age,gender,family,environment,life style,feed habit,disease and other factors.There is different level of clinic symptom for infants with high blood Pb level.High blood Pb has already been one critical factor to affect the growth of infants at this region and we need pay more attention.
