人发中含有多种微量元素,其含量与人的每日摄入量及其在体内的代谢情况有密切关系,可以利用它作为衡量人对微量元素接触、吸收、代谢程度以及其对机体危害程度的一种指标。因而自六十年代以来,发样中微量元素的分析,在临床营养、环境污染及实验室的研究中已相当普遍。人发中微量金属元素的测定方法有原子吸收法、皑化波极谱法,电感耦合高频法,等离子发射光谱法及荧光光度法等。我们于一九八六年用火焰原子吸收分光光度法测定人
Human hair contains a variety of trace elements, its content and the daily intake of human and its metabolism in the body are closely related, you can use it as a measure of human exposure to trace elements, absorption, metabolism and its harm to the body An indicator of the degree. Therefore, since the 1960s, the analysis of trace elements in hair samples has been quite common in clinical nutrition, environmental pollution and laboratory research. Determination of human hair trace metal elements are atomic absorption spectrometry, decay Polarography, inductively coupled high-frequency method, plasma emission spectrometry and fluorescence spectrometry. We measured human by flame atomic absorption spectrophotometry in 1986
