Analyses of fish tissues are carried out routinely by a number of laboratories to monitor the levels of contamination of the marine environment and food by toxic elements, such as heavy metals. To improve and control the quality of such determinations, the Community Bureau of Reference (BCR) has organised a certification campaign which enabled the production of a reference material (cod muscle CRM 422) certified for its contents of As, Cd, Cu, Fe, Hg, I, Mn, Pb, Se and Zn. This material was collected in the southern part of the North Sea, carefully prepared (filleted and crushed under liquid nitrogen) and its homogeneity and long-term stability were verified. This paper presents the certification work performed.
