Abstract

The first H₂ data from a landfill leachate plume are presented, and an alternative partial equilibrium approach is used to relate the H₂ concentrations to specific redox processes. The approach implies that terminal electron-accepting processes (TEAP) occur at negative ΔG_r values near the thermodynamic equilibrium, and that the fermentative H₂ production is overall rate limiting. ΔG_r values of TEAPs were calculated, assuming partial equilibrium, using H₂ concentrations and redox process reactants and products from the Grindsted Landfill. Combined with a threshold value, the calculated values predict which TEAPs can occur via H₂ oxidation.
