微量元素与人体健康的问题,是国内外学者瞩目.人们普遍关心的问题.据研究在动植物体中所含元素有60多种. 人体内的元素,按其含量的多少,可分为常量元素(含量在万分之一以上)和微量元素(含量在万分之一以下).常量元素有C、H、O、N、S、P、Cl、Na、K、Ca、Mg等,约占人体总质量的99.95%,微量元素有Fe、Zn、Cu、Mn、Mo、Co、Ge、Ni,Cr、Se、F、Br、I、Si、Sr、Ba、Al、Ga、In、Pb、Sn、As、Sb、Ti、Zr、Hf、V、Nb、Ta、Cd、Hg等,约占人体总质量的0.05%.
The problem of trace elements and human health is a topic of concern among scholars at home and abroad. People are generally concerned about the problem. According to the research, there are more than 60 elements contained in animals and plants. The elements in the human body can be divided into constants according to their contents. Elements (above 10,000th of the content) and trace elements (contains less than one ten-thousandth). Constant elements include C, H, O, N, S, P, Cl, Na, K, Ca, Mg, etc. 99.95% of the total body mass, trace elements include Fe, Zn, Cu, Mn, Mo, Co, Ge, Ni, Cr, Se, F, Br, I, Si, Sr, Ba, Al, Ga, In, Pb , Sn, As, Sb, Ti, Zr, Hf, V, Nb, Ta, Cd, Hg, etc., accounting for about 0.05% of the total body mass.
