| Research Abstract |
This study aims to apply multiple stable isotope methods to the aquatic and terrestrial ecosystem based on the isotopic information of geological and atmospheric studies, since material in biota are derived essentially from the atmosphere and lithosphere through water. We collected a set of water, biota, sediment, soil, and rock at most sites and analyzed their elemental and stable isotopic data. New findings based on multiple stable-isotopes demonstrate the usefulness of the environmental traceability method as an environmental diagnosis in elucidating interactions of geology, water, and atmosphere. To appeal this method to general society, the research results have been opened on seminars for citizens and published books.
