Project NameRIHN Center Laboratory and Analysis Division
Project LeaderTAYASU, Ichiro

 

○Research Subject and Objectives

The Laboratory and Analysis Division organizes three types of collaborative study in the Phase III Medium-Term Plan.

(1) Research collaboration with research projects: The division manages eighteen basement laboratories dedicated to various analytical needs. The division is responsible for maintaining state-of-the-art facilities, especially stable isotope mass spectrometers, and collaborates with research projects. 

(2) Research collaboration with core projects: A core project FR entitled “Proposal and verification of the validity of isotope environmental traceability methodology in environmental studies (FY2017-2019)” seeks to establish a methodology for how to use the concept of environmental traceability using multiple isotope ratios. The division collaborates with the project in an analytical viewpoint.

(3) Research collaboration with universities via “Environmental Isotope Study”: The division provides “Joint Research Grant for the Environmental Isotope Study” for universities and affiliated institutions throughout Japan, allowing them to use the facilities and exchanging research information. From the FY2016, the division has started the two types of collaborations, “Collaborative research with the Division” or “General collaborative research”.

○Progress and Results in 2019

The division installed or maintained various analytical instruments in the laboratories.

The division accepted 56 proposals of “(A) General collaborative research”, 11proposals of “(B) Collaborative research with the Division”, 4 proposals of “(C) Collaborative research with Environmental Traceability Project” and 10 proposals of “(D) Collaborative research with Ecosystem Traceability Project” in FY2019, under “Joint Research Grant for the Environmental Isotope Study”.

The division organized a session in JpGU2019 entitled “H-TT18: Development and application of environmental traceability methods” on 28 May 2019. 17 oral and 11 poster papers were presented in the session. We invited Prof. Gabriel J. Bowen(University of Utah)to our session and asked him to present a talk “Establishing, quantifying and monitoring connectivity in hydrological systems using stable isotopes” in RIHN on 30 May, 2019.

The division organized a short course of Environmental Isotope Study: Course 1 for light elements (27 - 30 August) and Course 2 for heavy elements (3-6 September). 13 researchers and students attended the course.

The division organized the sixth annual symposium of Environmental Isotope Study on 20 December. 102 researchers and students attended the symposium.

○Future Themes

The division considers that “Environmental Isotope Study” is one of the most important function of RIHN as an Inter-University Research Institute Corporation. Toward the Phase IV Medium-Term Plan of the institute, the division continuously develops analytical techniques to collect various environmental information in order to solve environmental issues.
