| Outline of Final Research Achievements |
Accumulation of REEs into radular teeth of chiton was investigated with material scientific technique. Two dimensional distributions of elements in a tooth of chiton, especially Sr, a key element of environmental monitoring, were indicated with micro PIXE and laser ablation MS. Quantitative analyses with atomic absorption spectroscopy and ICP-MS were examined to the teeth of chiton and elucidated that the teeth of chiton accumulated REEs at high concentration in hundred thousand times of those of seawater.
