摘　　要：无机元素与人体健康密不可分,虽然无机元素在体内的含量微乎其微,但是却起到了重要的生理作用。一般来说,无机元素在人体内有一个最适浓度范围,当其不足或浓度超过某一限度后就可能对人体健康造成不良影响。目前,用于测定人体无机元素含量的常用检材为血液和尿液,而头发具有易取材、易储存以及检测时限长等优势越来越被重视。近年来,许多学者发现头发中无机元素含量与人体健康有着密切的关系,头发作为无机元素分析的检材越来越受到人们的重视。因此,综述了近年来国内外关于头发中无机元素测定的发展动态,其内容主要包括头发的清洗方法的对比;头发中无机元素的提取方法和分析技术。Inorganic elements are closely related to human health. Although their concentrations are tiny, inorganic elements play an important role in human health. In general, inorganic elements have an optimum concentration range in human body. Lack or excess of inorganic elements may be harmful to human health. Although blood and urine are the most common biological materials used to determine the levels of many metals or metalloids, the analysis of hair has certain advantages, including the simple matrix, easy sampling, transfer and storage. Additionally, while metal concentrations in blood and urine decrease rapidly after exposure, hair appears to be of greater value in evaluating past and ongoing exposure to high levels of metals. Recently, many scholars have found that the content of inorganic elements in hair is closely related to human health. Therefore, hair, as a new type of sample for inorganic elements analysis, has been paid more and more attention. This article reviews the recent development at home and abroad on the determination of inorganic elements in hair, including comparison of washing approaches, extraction methods and analysis techniques.
