Underanaerobic conditions, microbial reduction of NO3 to N2(g) to oxidize dissolved organic carbon (DOC) is the principal NO3 attenuation process in groundwater aquifers (Matchett et al., 2019).2 p.application/pdfeng(c) Abu, A. et al., 2021DesnitrificacióCicles biogeoquímicsContaminació de l'aiguaIsòtops estables en ecologiaDenitrificationBiogeochemical cyclesWater pollutionStable isotopes in ecological researchinfo:eu-repo/semantics/article7074192021-03-01info:eu-repo/semantics/openAccess
