|Abstract:||The Italian Nat. programme for research in Antarctica has recently launched a project for preparation of CRMs to be used for QC of analyses performed on environmentally significant materials. The suitability of CRMs to verify the accuracy of experimental measurements acknowledgedly depends, among others, on the degree of similarity of their matrix composition and analyse levels to those expected for real samples. therefore, three CRMs to be certified for elements are planned; marine sediment, ocean water and krill. Regarding the first two matrices, amounts of ca. 100 kg and ca. 100 litres, respect., habe been collected during the IX (1993-1994) antarctic expedition, while krill was taken in the course of the X (1994-1995) campaign. The sediment has been processed into 500 bottles, each containing 75 g of material and is now ready for distribution to interested laboratories involved in chemical measurements of antarctic matrices.|
