Trace element characterization by INAA of three sediments to be certified as standard reference materials

摘要

Three environmental matrices proposed as Certified Reference Materials, issued by the EU Standards, Measurement and Testing Programme (SMTP) formerly Bureau Communautaire de Reference (BCR) have been characterized for their trace element contents. The materials are: BCR 277 R Estuarine Sediment, BCR 280 R Lake Sediment and BCR 320 R Channel Sediment. Several trace elements, including As, Co, Cr, Fe, Mn, Ni, Sb, Sc, Th, U and Zn have been determined by our laboratory using Instrumental Neutron Activation Analysis (INAA). Our contributed values are being considered for the final certification. (C) 2004 Published by Elsevier B.V.
