人体中若干微量元素含量的消长与某些疾病密切相关,因此检测人体中的微量元素对疾病的诊断、治疗和预防以及探索微量元素与疾病之间的关联,研究其生理和病理作用都有十分重要的意义。原子吸收光谱法(AAS)及感应耦合等离子体发射光谱法(ICP-AES)由于具有灵敏度高、进样量少、操作简便和快速的特点,已成为进行人体微量元素分析的有效方法之一。一、人体中的微量元素目前,至少已掌握人体中近50种元素的含量。通常人们把占人体总重量的1/10000以上者称为宏量元素,主要有O、C、H、N、P、S、Cl、Ca、K、Na和Mg等,共占人体总重量的99.95％。少于1/10000以下者称为微量元素,约有40余种,仅占人体总重量的0.05％。
The growth and decline of some trace elements in the human body are closely related to some diseases. Therefore, it is very important to detect the trace elements in the human body to diagnose, treat and prevent diseases and to explore the correlation between trace elements and diseases, and to study their physiological and pathological effects Significance. Atomic absorption spectroscopy (AAS) and inductively coupled plasma-atomic emission spectrometry (ICP-AES) have become one of the most effective methods for microelement analysis in the human body because of their high sensitivity, small injection volume, simple and quick operation. First, the trace elements in the human body At present, at least have mastered the content of nearly 50 kinds of elements in the human body. People usually weigh more than 1/10000 of the total body weight as macroelements, mainly O, C, H, N, P, S, Cl, Ca, K, Na and Mg, 99.95%. Less than 1/10000 The following are called trace elements, about 40 species, accounting for only 0.05% of the total body weight.
