Notes:
Reference materials of animal origin have been analyzed for Cd, Cu, and Pb contents by voltammetry using ECO-TRIBO Polarograph with pentype renewed Hg electrode after dry ashing in superoxidizing atmosphere (mixture of O3 + O2 + NOx). The contents of all metals mentioned were independently determined in aliquots of identical digests by atomic absorption spectrometry (AAS). Statistical evaluation showed good correlation between both methods. Moreover, dectrochemical results the obtained for biological certified reference material (CRM) 12-02-01 Bovine Liver are in very good agreement with certified values for Cd and Pb.
