人体中除常见的碳、氢、氧、钙、磷、镁、钾、钠、氯、硫、氮等11种元素外,还存在一些含量甚微,以往用一般分析方法不能精确检测出来的微量元素。随着科学技术的发展,目前可以很精确测定这些微量元素的含量。据认为,凡存在于机体内,具有一定的功能,其浓度可用μg/g 或μg/dl 来表示的元素,都可列入微量元素的范围。通过大量研究表明,微量元素对人体具有十分重要的作用,为人体健康所必需,因而越来越为国内外医学界所重视。目前已知有14种微
In addition to the common elements of carbon, hydrogen, oxygen, calcium, phosphorus, magnesium, potassium, sodium, chlorine, sulfur, nitrogen and other 11 kinds of elements in the human body, there are still some minor contents that can not be accurately detected by conventional analytical methods element. With the development of science and technology, the content of these trace elements can be accurately measured at present. It is believed that those who exist in the body, has a certain function, the concentration can be expressed in μg / g or μg / dl elements, can be included in the range of trace elements. Through a large number of studies have shown that trace elements on the human body has a very important role, necessary for human health, which is increasingly valued by the medical profession at home and abroad. Currently there are 14 kinds of micro
