Resumo
Reference materials are important tools in the quality assurance of analytical results as they
may be used in method validation, calibration of instruments and in the realization of the
traceability of analytical results to stated references. This study aims to be a contribution to
metrology in chemistry in Brazil and describes the preparation of a mussel reference material
using the Perna perna species. This mussel species is abundant in most part of the Brazilian
seashore and is currently being used in biomonitoring studies in our laboratory. It also has
economical importance due to its growing cultivation in aquaculture farms for human
consumption. In a previous communication, various aspects of the preparation of the mussel
reference material such as sampling, sample pretreatments and freeze-drying were described. In
the present paper further developments are presented, comprising grinding and sieving,
homogenization and gamma ray sterilization. Physical and chemical characterization following
internationally agreed recommendations are being performed, with emphasis on the assessment
of the stability of the material, its homogeneity status and the layout for certified values
assignment via an interlaboratorial measurement program. Preliminary results for the
concentration of elements such as As, Br, Co, Cr, Fe, K, Na, Se and Zn determined by
instrumental neutron activation analysis and Cd, Hg and Pb determined by atomic absorption
spectrometry, are also presented with corresponding measurement uncertainties.
