Response of Anammox Consortia to NPs

Anaerobic ammonium oxidation (anammox) is an efficient and environmentally friendly process for biological nitrogen removal.The widespread application of ferroferric oxide (Fe3O4) NPs leads to an enormous increase in their release into wastewaterTherefore, considering environmental accumulation and biological toxicity of Fe3O4 NPs, it is imperative to investigate potential risks by high Fe3O4 NPs concentration to anammox community.

厌氧氨氧化（Anaerobic ammonium oxidation，anammox）是一种高效且环境友好的生物脱氮工艺。当前，四氧化三铁（ferroferric oxide, Fe₃O₄）纳米颗粒（nanoparticles，NPs）的应用场景不断拓展，其向废水环境中的释放量显著增加。鉴于四氧化三铁纳米颗粒的环境累积特性与生物毒性，亟需探究高浓度四氧化三铁纳米颗粒对厌氧氨氧化菌群的潜在风险。
