采用电感耦合等离子体发射光谱法（ＩＣＰ－ＡＥＳ），对云南省白族长寿区的大米、玉米和 黄豆中的１９种元素进行了测定。结果显示，在３种谷类粮食中，均含有人体必需的３种常量元 素 Ｍｇ、 Ｐ、Ｓ及４种微量元素 Ｃｒ、 Ｍｎ、 Ｆｅ、 Ｚｎ，其中 Ｐ、Ｓ、Ｍｇ、Ｆｅ、 Ｚｎ的含量最高，其次是 Ｍｎ、Ｃｒ。这７种人体必需元素在３种谷类粮食中的含量分布不一，以黄豆中含量为最高。该地区 人能健康长寿与其粮食中富含这些生命元素密切相关。
Inductively coupled plasma atomic emission spectrometry (ICP-AES) was used to determine the 19 elements in rice, corn and soybean in Changshou of Bai nationality. The results showed that the three kinds of cereal grains contained three kinds of essential elements Mg, P, S and four kinds of trace elements Cr, Mn, Fe, Zn, among which P, S, Mg, Fe and Zn were the highest , Followed by Mn, Cr. The seven kinds of human essential elements in the distribution of three kinds of cereal grains in different levels, the highest content of soybeans. The health and longevity of people in the region are closely linked to the abundance of these elements of life in their food.
