Certified reference materials are needed to ensure the quality of analysis of biological matrices in the aquatic environment both for the control of contamination and for the assessment of the quality of food following the requirements of national or Community legislation. Fish and plankton materials are used as indicators of pollution and to compare the levels of contamination of different areas. Fish is also analysed for nutritional studies and for assessing human exposure to toxic elements. Owing to the need of CRMs for the analytical quality control of trace element determination in these matrices, the BCR of the Commission of the European Communities has already produced a mussel tissue (CRM 278) certified for its content of As, Cd, Cr, Cu, Fe, Hg, Mn, Pb, Se and Zn. Two additional materials were recently certified for the following element contents: (i) CRM 414 (plankton) certified for As, Cd, Cr, Cu, Hg, Mn, Ni, Pb, Se, V and Zn; (ii) CRM 422 (cod muscle) certified for As, Cd, Cu, Fe, Hg, I, Mn, Pb, Se and Zn. This contribution presents the certification campaigns and the results obtained.
