摘要
目的探讨婴幼儿发中铜锌铁含量的正常水平及营养状况。方法采集婴幼儿发样进行预处理后用火焰原子分光光度法测定其铜锌铁含量,并对测定结果进行统计学分析。结果 0~3月龄婴儿发中铜锌铁含量均处于较高水平,随着年龄的增长至4~12月龄其含量均呈下降趋势,且以锌下降为甚。随着年龄进一步增长至13~24月,其含量略呈回升趋势。结论婴幼儿应加强微量元素的营养补充。
[Objective]To study the normal levels and nutrition status of copper,zinc and iron in hair of infants.[Methods]The hair samples were collected from infants.After pretreatment,the contents of copper,zinc and iron were measured by flame atomic spectrophotography,and the results were analyzed statistically.[Results]The contents of copper,zinc and iron of infants aged 0~3 months remained at high level.The contents gradually decreased with increasing of age in 3~12 months old infants,especially zinc content.The contents increased slightly again in 13~24 months old infants.[Conclusion]The trace element supplement should be strengthened in infants.
