Application of the nitrogen-to-argon ratio to understand nitrogen transformation pathways in landfills under in-situ stabilization
The goal was to apply the ratio of N2 to argon to investigate the nitrogen transformation in aerobic and anaerobic landfills. The results showed N2-generating and N2-consuming processes occurred during landfill stabilization. Microorganisms responsible for nitrification, ammonification, denitrification, and anammox were assesed to further understand the nitrogen transformation in landfills.
