Beschreibung
Recent reports indicate that atmospheric levels of reactive nitrogen species (RNS) are rising globally, primarily due to increased fossil fuel combustion for energy production and agricultural activities. Fossil fuel usage is altering air composition by adding compounds like NH₃ and NOₓ, along with related species such as HNO₃, HONO, NO₃, N₂O₅, NO₃⁻, peroxyacetyl nitrate (PAN), NH₄⁺, and others. These RNS are negatively impacting terrestrial and aquatic ecosystems, with several of them being major contributors to climate change. Elevated concentrations of RNS in air and water are also harmful to human health. Additionally, managing nitrogen waste poses a significant economic challenge, with its global impact estimated to range between US$340 billion and US$3.4 trillion annually when considering effects on human health and ecosystems. Food waste exacerbates these issues by disrupting the nitrogen cycle.
An overview of Reactive Nitrogen to explain reactive nitrogen compounds (RNS) and their types Includes environmental consequences as climate impacts of RNS like N₂O and their role in global warming Presents trends in nitrogen emissions, consumption, and environmental consequences
