| Research Abstract |
The major-to-ultratrace elements in soft tissue of Tridacna crocea and coral with symbiotic zooxanthellae in unique seawater in coral reefs and Lucinoma annulatun chemosynthetic bacteria living in sea floor were determened by an inductively coupled plasma mass spectrometry(ICP-MS), an inductively coupled plasma atomic emission spectrometry(ICP-AES), and a CHN corder. Then, the characteristics for metallomics of their symbiotic animals were investigated from various points based on multielemental data. Furthermore, the zooxanthellae could successfully be isolated from Tridacna crocea and they were analysed after acid-digestion. Simple methods for determination of trace elements and chemical speciation analysis of phosphorus were developed and applied to minitoring of seawater in coral reefs.
