The amount of prompt NO produced in combustion systems is relatively small compared with the total NO formation. However, prompt NO is still formed at low temperatures and is one of the features in producing ultra-low NO burners. The nitric oxide reacts with other species in the atmosphere to give various other nitrogen oxides, namely NO2 and nitrogen pollutants. 

Nitrogen pollution has received far more attention than that of phosphorus for two reasons. First, it has been considered as the nutrient-limiting primary production in estuaries and coastal waters. Second, its loading into the coastal zone has been far greater than that of phosphorus (Figure 24.21). It is also more efficiently exported into the ocean due in part to formation of iron phosphate minerals in anoxic estuarine sediments.

The failure to adequately control non-point source nitrogen pollution to date — in the few cases where such controls have been attempted — probably lies in structural problems with the apphcation of the control strategies (Boesch et ai, 2001 Boesch, 2002 Howarth, 2005 Howarth et al., 2005 NRC, 2000). An analysis of some problems with the Chesapeake Bay case is illustrative ...

In a few cases, nitrogen pollution affects humans directly. Nitrates pollute groundwater supplies in many farming areas. Nitrogen oxides in the air turn into ozone, harming both vulnerable humans and plant life. 

Nitrogen is a key element of many biogeochemical processes and can be both a nutrient limiting the productivity of terrestrial and aquatic ecosystems and a pollutant, which excessive accumulation in biogeochemical food chains leads to many environmental problems. The main anthropogenic sources of nitrogen pollution are related to fertilizer application, waste production and emission of gaseous species. 

Both sulphur and nitrogen pollutants are emitted into the air in the form of oxides, SO2 and NO respectively, which may then further be oxidized during the transport in the air. The processes of deposition of air pollutants are ...
