THE CERTIFICATION OF THE CONTENTS (MASS FRACTIONS) OF CD, PB, AS, HG, SE, CU, ZN, FE AND MN IN THREE LYOPHILIZED ANIMAL TISSUE REFERENCE MATERIALS
The report describes the preparation and certification of three lyophilized animal tissue reference materials (CRM 184 Bovine Muscle, CRM 185 Bovine Liver and CRM 186 Pig Kidney) for their contents (mass fractions) of elements of toxicological and nutritional importance: Cd, Pb, Hg, Se, Cu, Zn, Fe, and Mn. Indicative values are also given for Na, K, Cl, Mg, Ca, P, I, Ni and Cr. Details are given of a preliminary intercomparison of methods for these elements in a bovine liver sample, homogeneity and stability studies on the three reference materials and, the results and evaluation of the certification exercise which involved 28 Community Laboratories. Summaries of the certification methods are also presented. The report concludes with a comparison of results obtained by solid sampling Zeeman AAS with the certified values for Pb and Cd and a discussion of the most common sources of error in determining the elements of interest and the steps to be taken to control them.
