微量元素营养作为生物和医学领域中的一个独立分支,可能是近50年才逐渐形成的。它的进展是与近代科技飞速发展分不开的。特别是尖端物理和化学分析手段的建立,为生物样品中含量极微的无机元素的生物学作用研究奠定了基础。自然界中天然存在的元素在生物体内几乎都可以找到。按其在体内的含量,以占体重1/万为界,分为常量元素和微量元素两类。已知常量元素有碳、
As an independent branch of biology and medicine, micronutrient nutrition may have evolved over the last 50 years. Its progress is inseparable from the rapid development of modern science and technology. In particular, the establishment of cutting-edge physical and chemical analysis methods has laid a foundation for the study of the biological effects of inorganic elements with extremely low content in biological samples. Naturally occurring elements in the body can be found almost everywhere. According to its content in the body, taking the body weight of 1 / million for the community, divided into two types of constant elements and trace elements. The known constant elements are carbon,
