Today, nitrogen pollution is one of the most pressing pollution issues facing humanity, threatening our environment, health, climate and ecosystems.In the urban atmosphere, nitrogen oxide (NO x ═NO + NO 2)-related reactions dominate the formation of nitrous acid (HONO).Other planets and . It is shown that lightning and subsequent atmospheric .Unlike carbon, which is stored primarily in sedimentary rock, most nitrogen occurs in the atmosphere as an inorganic compound .Another reason why nitrogen is abundant in the atmosphere is that nitrogen gas molecules are more stable than oxygen gas molecules. However, humans learned in the early 1900s to change N2 into reactive forms of N to create N-based fertilizers to increase plant growth. Slow geological processes, including the formation of sedimentary rock and fossil fuels, contribute to the .To summarize: NO 2: Nitrogen Dioxyde ; NO: Nitric Dioxyde ; NO x: Oxides of Nitrogen = {NO 2 +NO} .

Nitrogen from the Atmosphere

Despite the importance of nitrogen and its overwhelming abundance in the atmosphere, N 2 is virtually inert; hence, fixed inorganic nitrogen [most commonly nitrate (NO 3 –) and ammonium (NH 4 +) ions] often limits primary productivity in both marine and terrestrial ecosystems (2, 4, 5).Most atmospheric nitrogen enters the soil by nitrogen-fixing microorganisms. Under great pressure, at a temperature of 600°C (1112°F), and with the use of a catalyst (which facilitates chemical reactions), atmospheric nitrogen and hydrogen can be combined to form ammonia (NH 3).Atmospheric nitrogen thus holds roughly 90% of the nitrogen relevant to the global nitrogen cycle, with nearly all of that nitrogen in the form of N 2 (Chapin et al.Like carbon, nitrogen has its own biogeochemical cycle, circulating through the atmosphere, lithosphere, and hydrosphere (Figure 5). We determined the quantities of ON .
