[H-TT18] Development and application of environmental traceability methods

Fri. May 27, 2022 3:30 PM - 5:00 PM 201B (International Conference Hall, Makuhari Messe)

convener:Ichiro Tayasu(Research Institute for Humanity and Nature), convener:Ki-Cheol Shin(Research Institute for Humanity and Nature), Katsuyuki Yamashita(Graduate School of Natural Science and Technology, Okayama University), Chairperson:Ichiro Tayasu(Research Institute for Humanity and Nature), Ki-Cheol Shin(Research Institute for Humanity and Nature)

Modern society uses almost all the elements present in the natural world. Although there have long been calls for the sustainable use of the resources that provide these elements and the building of human societies that are in harmony with the environment, the survival of the human race is increasingly at risk as a result of qualitative changes to the environment as a whole. Implementation by the society of methodologies for diagnosing and tracking these various elements of the natural environment and their relationships with humans are now required.
Elements cycle within and among the Earth system spheres, human society, and the human body. Information on the concentrations and stable isotopes of elements is a powerful tool for tracing this cycling and has been applied in studies of atmosphere-hydrosphere circulation, ecological systems, and the life, health, and history of humans. We propose a session to discuss the development and applications of environmental traceability methods toward the goal of establishing traceability in natural and human systems.
We encourage the presentation of research integrating isotopic information in various disciplines, such as geochemistry, hydrology, ecology, geology, mineralogy, anthropology, food science, and forensics. We call the research Environmental Isotope Study.
