چکیده انگلیسی
In this context, an interlaboratory comparison for trace elements in tuna fish matrix was organised in cooperation with the Institute for Reference Materials and Measurements (IRMM), Joint Research Centre, European Commission. Freeze-dried tuna fish samples were sent out to the NRLs for chemical elements in the Member States. Participants were requested to carry out at least three independent measurements of the elements As, Cd, Cr, Cu, Fe, Hg, Pb and Zn. The assessment of the proficiency was based on the z-score approach and a relative bias better than or equal to 10% of the target value was deemed to be an acceptable performance for this kind of measurements. On this basis, more than 50% of the laboratories returned accurate results for As, Cu, Fe, Hg and Zn, whereas the analysis of Cd, Cr and Pb appeared to be more problematic.
