| Outline of Final Research Achievements |
In the present study, the concentrations of trace elements in each organ in reef-building coral were multielemently measured by inductively coupled plasma mass spectrometry (ICP-MS). As a result, it was elucidated that the concentrations of Fe, Zn, and Cd in the symbiotic zooxanthellae were remarkably over 100000-fold larger than those in seawater. Furthermore, the breeding experiment using seawater tanks, in which enriched stable isotopes were added, were carried out to investigate the intake processes of trace elements from seawater to each organ in the coral. As the results, it was suggested that Zn and Fe were intaken in zooxanthellae from seawater after 24-48 hours and provided into soft tissues, and Zn and Pb were stored in skeleton via soft tissues.
