【摘要】 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。更多还原

【Abstract】 The content of 19 elements in the rice, corn and soybean for an "long-lived area" of Bai nationality in Yunnan province was determined by ICP-AES. The results showed there were three common elements such as Mg, P, S and four trace elements such as Cr, Mn, Fe, Zn that are necessary to humans in three kinds of the cereals. The content of P, S, Mg, Fe, Zn was ranked the highest, Mn and Cr less. The content of seven kinds of essential elements in the cereals was different and the content of these elements in soybean was the highest. It is suggested that the longvity of people in this area has a close relationship with these elements in the cereals.更多还原
