摘　　要：采用低温干灰化法制备样品，ICP—AES同时分析毛皮动物貉被毛组织中多种微量元素。Ba、Be、Cd、Si、Y和zn的测定下限为1．0～9．0ng·g-1级，B、Fe、La、Mg、Mo、M、n、Co、cr、Cu、Sr、V和Zr为0．01～0．09μg·g11级，In、Th、P和为0．13～0．23μg·g。级，大于1的只有Nb是1．08μg·g。级。该方法经国家人发标准物质GBW07601验证，测得方法相对误差在0．83％～9．59％之间，相对标准偏差在0．81％～5．20％之间，各项检测指标均能满足生物样品检测要求，分别测得健康种貉、自咬症轻重病貉被毛中的22种微量元素，健康貉的B、Co、Cr和Ni微量元素含量明显高于病貉，而Al、Ba、Be、Cd、Mo、Pb、Sr、Ti和Zr元素含量较低。该方法可以满足生物样品元素分析的要求。The sample was prepared by low temperature dry ashing method. Trace elements of fur tissue on fur-bearing an- imal raccoon dog were analyzed by inductively coupled plasma-atomic emission spectrometry （ICP-AES）. The lowest quanti- tatively determinable concentration were between 1.0 N 9, 0 ng · g- 1 grade for trace elements Ba, Be, Cd, Si, Y and Zn, and were between 0. 01 -0. 09 μg · g-1 grade for microelement B, Fe, La, Mg, Mo, Ni, Ti, Co, Cr, Cu, Sr, V and Zr, and were between O. 13 -0.23 μg · g-1 grade for In, Th, P and Pb. Only one of greater than 1 on the lowest quantitatively determinable concentration for Nb was 1.08 μg · g-1 This method was verified by national hairs standards GBW07601. The relative error was between O. 83% - 9.59%. The relative standard deviation was between O. 81% - 5.20%. These 22 elements were analyzed for fur of health and illness raccoon dog. In health raccoon dogs, the content of elements B, Co, Cr and Ni were apparently higher than that in illness ones, while the content of elements Al, Ba, Be, Cd, Mo, Pb, Sr, Ti and Zr were lower than that in illness ones. The determination data were competent for standards of biological sample analysis.
