Corrigendum to “Anaerobic ammonium oxidation coupled to arsenate reduction, a novel biogeochemical process observed in arsenic-contaminated paddy soil” [Geochim. et Cosmochim. Ac., 335 (2022) 11–22, (S0016703722004008), (10.1016/j.gca.2022.08.020)]

The authors regret that on page 16, the last sentence in the 1st paragraph and the Equations 1-3 of Section 4.1, and on page S3 of the Supplementary Information, the authors have been made aware of an error in the free energy of formation for AsO₄^3- and AsO₂^-. A mistake in the Gibbs energy values of AsO₄^3- and AsO₂^- were -55 and -83.66 kJ/mol, which need to be corrected to be -155 and -83.66 kcal/mol, respectively. Unit conversions in the calculation of Equations 1-3 were not performed and produced wrong Δ [Formula presented] value. We present here corrected Δ [Formula presented] value of Equations 1-3 and attached a corrected Supplementary Information as below. Error: Accordingly, we predicted that anaerobic ammonium oxidation coupled to As(V) reduction would also generate N₂, NO₂^-, or NO₃^- similar to Feammox but would yield more energy through the following reactions (Equations 1-3) (see Supplementary Material for the calculation of Δ [Formula presented]): [Formula presented] [Formula presented] [Formula presented] Corrected: Accordingly, we predicted that anaerobic ammonium oxidation coupled to As(V) reduction would also generate N₂, NO₂^-, or NO₃^- similar to Feammox and would yield energy through the following reactions (Equations 1-3) (see Supplementary Material for the calculation of Δ[Formula presented]): [Formula presented] [Formula presented] [Formula presented] Though the Gibbs energy need to be corrected, our discussion and conclusion still works. All the three Asammox pathways were energetically favoured (Δ [Formula presented] < 0) and Asammox to N₂ stoichiometrically obtained most energy (minimum Δ [Formula presented]) among the three pathways.
