The chemical composition of coral skeleton and clamshell is closely linked to the composition of surface sea water in which skeletal or shell calcium carbonate is precipitated. For this reason, several chemical components in coral and clam have been determined to be indicatrs of sea surface environmental conditions. However, there is no reference material having the same chemical composition as coral or clam. Therefore, GSJ/AIST has issued the reference materials JCp-1 (Coral Porites sp.) and JCt-1 (Giant Clam Tridacna), for the determination and evaluation of elements in coral, clam and other biogenic carbonates. In this study, collaborative analysis for the certification of reference materials JCp-1 and JCt-1 was carried out in ten laboratories. The analytical data were compiled for 9 components (CaO, Ba, Fe, K, Mg, Mn, Na, P and Sr). The ICP-AES and AAS were mainly used, and the analytical results agreed relatively well. In the statistical analysis, the reference values were mainly decided using the robust method. ISO typically recommends that data should be submitted from no fewer than 15 laboratories for deciding the certified values; the reference values given in this paper could be considered as preliminary certified values.
