摘要 使用同步辐射 X 射线荧光 (SRXRF) 可以同时测定人体血液、头发和胎盘、动物毛发、骨和肌肉组织、胆结石以及食物链中的一些物体（浆果、冰岛苔藓、雪松仁、蜂蜜）的多元素成分。测定了以下元素的浓度：K、Ca、Ti、V、Cr、Mn、Fe、Co、Ni、Cu、Zn、Ga、Ge、As、Se、Br、Rb、Sr、Y、Zr、Nb、Mo、Hg、Pb、Bi、Th、U。已开发出通过 SRXRF 方法测定元素组成的生物样品制备技术。分析了薄片状和片状样品多元素成分测定的特点。结果表明，SRXRF 对于估计生物底物多元素组成的具体特征具有相当丰富的信息。
Abstract The results of the use of synchrotron radiation X-ray fluorescence (SRXRF) are demonstrated for simultaneous determination of the multielement composition of human blood, hair and placenta, animal hair, bony and muscular tissues, gallstones and some objects of a food chain (berries, iceland moss, cedar kernels, honey). Concentrations of the following elements were determined: K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, Ge, As, Se, Br, Rb, Sr, Y, Zr, Nb, Mo, Hg, Pb, Bi, Th, U. The technique for preparing biological samples has been developed for determining the element composition by the SRXRF method. The peculiarities of determination of the multielement composition of thin and in form of tablets samples are analyzed. It is shown that SRXRF is fairly informative for estimating the specific features of the multielement composition of biosubstrates.
