Short summary
The terrestrial environment has been affected by tritium contamination. There is a need to assess the dynamics of organic hydrogen in soils in order to predict the fate of tritium. In the present study we traced carbon and hydrogen from plant-derived molecules and hydrogen from water in different soil types. The main findings of the work are that water is the main donor of organic hydrogen and the long-term fate of hydrogen (and tritium) will depend on the status of soil carbon dynamics.
