Toyoda Lab
Machine-translated · View original
The lab tracks the movement of trace gases such as greenhouse gases using stable isotopes.
AboutAbout the lab
The environmental dynamics of trace gases, approached through chemistry.
The Toyoda Lab studies how trace gases, such as greenhouse gases and ozone-depleting gases, circulate at the Earth's surface.
The lab develops methods to measure, with high precision, the concentrations and stable isotope ratios of very minor components in environmental samples.
In addition to collecting and analyzing samples on land, in the atmosphere, and in the ocean, the lab simulates environments in the laboratory to investigate reaction mechanisms.
Undergraduate graduation research and graduate research supervision are carried out in cooperation with the Yamada Lab in the same Department of Chemical Science and Engineering.
Key terms
- Stable isotope ratio
- A value showing the proportions in which atoms of the same element but with different masses are mixed
- Nitrous oxide
- A gas, also known as dinitrogen monoxide, that contributes to global warming and also destroys the ozone layer in the stratosphere
- Ocean acidification
- The process in which carbon dioxide that has increased in the atmosphere dissolves into seawater, shifting the properties of the seawater toward the acidic side

Using chemistry as a tool, the lab analyzes how trace gases such as greenhouse gases and ozone-depleting gases, as well as related substances, circulate at the Earth's surface. It works on developing high-precision methods for measuring concentrations and isotope ratios, collecting and analyzing samples at various sites, and analyzing reaction mechanisms through simulation experiments.
*Illustrative imageThe cycle of nitrous oxide
For nitrous oxide produced by microbes in soil and aquatic environments, the lab collects samples at various sites to measure concentrations and stable isotope abundances, and also conducts simulation experiments in the laboratory. It aims to clarify how nitrous oxide is produced and decomposed in each source.
*Illustrative imageThe effects of ocean acidification
How ocean acidification, which progresses as carbon dioxide dissolves in seawater, affects the microbes responsible for producing and consuming trace gases is still not well understood. Using experiments that simulate acidification, the lab examines changes in production rates and production processes from concentrations and isotope ratios.
*Illustrative imageThe cycle of hydrogen in the atmosphere
If hydrogen is used more widely as an energy source, its atmospheric concentration may rise. Using stable isotope ratios as clues, the lab aims to clarify the characteristics of various sources and sinks, as well as long-term variations in the hydrogen isotope ratio of the atmosphere.
*Illustrative imageMaking isotope ratio reference materials
Measuring stable isotope ratios requires accurate, internationally accepted reference materials. In cooperation with research institutions in Japan and abroad, the lab works on preparing and developing isotope ratio reference gases for nitrous oxide and methane.
