Nitrous Oxide from Abiotic Processes of Hydroxylamine and Nitrite in Estuarine and Coastal Ecosystems: A Review

Abiotic processes of nitrogen (N) are suggested to contribute nitrous oxide (N2O) production; however, the important role these in N2O emissions is invariably ignored. This review synthesized main abiotic hydroxylamine and nitrite associated biogeochemical controls estuarine coastal ecosystems. availably detected environments. The more production than environments, suggesting that plays an production. isotopic fractionation effects N can occur during enriched with increasing rates reactions. In addition, highly dependent on pH, oxygen, Fe2+, Fe3+, Mn4+ also triggered by substrate contents.
