外文摘要：Emerging ecological risks of Per - and polyfluoroalkyl substances (PFASs) in terrestrial environments have received extensive attention. Yet, their impact on microbially-mediated nitrification processes in soils remains insufficiently investigated. Through a 42-day microcosm incubation experiment, we examined how two representative PFASs exposure, i.e., perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic (PFOS), influence nitrification potential (PNR) and the community dynamics of ammonia-oxidizing archaea (AOA), bacteria (AOB), and complete ammonia oxidization (comammox) in calcareous soil. Both PFOA and PFOS exposure significantly enhanced PNR and the Chao1 index of AOA and comammox (P 4+, DON, and MBC/MBN as critical determinants of community assembly. Network analysis uncovered intensified cross-domain synergies between AOA and comammox, with Candidatus Nitrosocosmicus, Nitrososphaera, and Nitrosospira emerging as keystone taxa governing nitrification. Random forest and structural equation modeling indicated that PFASs exposure altered the nitrification by directly changing soil pH, NH4+, DON, and MBC/MBN and indirectly shifting AOA and comammox co-occurrence patterns. Our results underscored that PFASs contamination accelerates nitrogen cycling through reinforced AOA-comammox cooperation, potentially exacerbating nitrogen depletion in agroecosystems. ? 2025 Elsevier B.V.
