| Outline of Final Research Achievements |
Atmospheric concentration of molecular hydrogen (H2) is predicted to increase because of its use as energy source. However, the effect of human-induced hydrogen increase on the future atmospheric environment is difficult to evaluate because current global budget of hydrogen is not fully understood. This study aimed at development of rapid and concise procedure for measuring hydrogen isotope ratio, and isotopic characterization of hydrogen emitted from or consumed by several processes occurring in the biosphere.
