A pilot study for the preparation of a new reference material based on Antarctic krill
The preparation of new Certified Reference Materials (CRM's) in antarctic matrices forms the backbone of an ongoing project in the framework of the Italian National Programme for Antarctic Research. The first CRM of this kind (MURST-ISS-AI Antarctic Marine Sediment) is already available. The second phase of this undertaking, in turn, focuses on the certification of antarctic krill, a small shrimp extremely abundant in the Southern Ocean. This crustacean plays a key role in the food web and is also of potential interest as an environmental bioindicator. A CRM especially designed to check the accuracy of analyses in this matrix is deemed necessary and timely. The project aims at certifying a number of elements and organics, namely As, Cd, Cr, Cu, Fe, Hg, Mn, Ni, Pb and Zn. The quantification of these elements in the raw mass appears to be affordable by current analytical techniques with the average values ascertained in freeze-dried krill, as a rule being one order of magnitude higher. Information on the pretreatment of krill and details on the planned certification campaign are also given.
