摘要
用等离子发射光谱法检测了3 73位5 0岁以上老人头发中8种无机盐含量。结果表明,有71 2 %的男性及48 5 %的女性发钙含量低于正常参考值,有3 2 2 %的男性及3 9 8%的女性发铁含量低于正常参考值;镁、铜、锌、磷含量低于参考值的人数均在1 0 %以内。男、女发铅含量的均值分别是4 2 μg/g和2 1 μg/g ,差异有统计学意义。提示钙、铁缺乏是老年营养的主要问题。
minerals in hairs of 373 agers who are older than 50 were examined by ICP-AES. The results show that the amount of calcium in hairs of 71.2% males and 48.5% females are below the normal reference and the amount of iron in hairs of 32.2% males and 39.8% females are also below normal reference. The amount of lead in hairs of males and females are 4.2 μg/g and 2.1 μg/g, which have the statistic significance. All above show that the deficiencies of calcium and iron are still the main nutritional problems and the amount of lead in male hairs is higher than that in females.
