一白族长寿地区岩石土壤和泉水的元素分析

Analysis of inorganic elements in rock,soil and spring water from a area of longlived Bai nationality

用电感偶合等离子体发射光谱法（ＩＣＰ－ＡＥＳ），对一白族长寿地区的岩石、土壤和泉水进行了无机元素分析。结果表明，岩石、土壤和泉水中均含有人体必需的Ｃａ、Ｍｇ、Ｎａ（Ｋ）、Ｐ、Ｓ５种宏量元素及Ｆｅ、Ｚｎ、Ｃｕ、Ｍｎ、Ｍｏ、Ｃｒ、Ｓｒ、Ｓｅ８种微量元素。

Inorganic elements in rock,soil and spring water from a area of longlived Bai nationality in Yunlong country of Yunnan provine have been analyzed by ICPAES.The results show there are five macroelements such as Ca,Mg,Na(K),P,S and eight trace elements such as Fe,Zn,Cu,Mn,Mo,Cr,Sr,Se,which are necessary to human,in all of rock,soil and spring water.It is suggested that such environment with a good trace element system would closely associate with the phenomenon of longevity and low incidence of the people in the area.
