【摘要】 目的调查广西河池地区787例1~3岁幼儿静脉血中6种元素的含量。方法采用火焰原子吸收法检测787例幼儿锌、铜、铁、钙、镁、铅6种微量元素含量。结果血钙均值在正常参考值范围,其他5种元素的均值都低于正常值。男性幼儿血锌、铜、铁、钙、镁均值高于女性幼儿(P<0.01)。锌、铅在各民族的分布差异有统计学意义(P<0.01),其他4种元素分布的民族差异均无统计学意义(P>0.05)。结论河池地区1~3岁幼儿锌、铜、铁、镁含量偏低与饮食结构有关,铅含量偏高与居住环境相关。更多还原

【Abstract】 Objective To investigate the content of six element in vein blood of 787 children aged 1～3 in Hechi area.Methods The content of zinc(Zn),cuprum(Cu),ferret(Fe),calcium(Ca),magnesium(Mg),lead(Pb) were detected by flame atomic absorption spectrometry in 787 blood samples.Results Average value of the Ca was in normal reference range,while the other 5 elements were lower than normal value.Average value of boys’ Zn,Cu,Fe,Ca,Mg is higher than girls’(P<0.01).The difference of Content of Zn and Pb among all 6 ethnic groups showed statistic significance(P<0.01),while it wasn’t found in the other four elements(P>0.05).Conclusion In children aged 1～3 of Hechi area,There is a correlation between low content of Zn,Cu,Fe,Mg and dietary structure.And there is a correlation between high content of Pb and resdential environment.更多还原
