NOx is a generic term for the mono-nitrogen oxides NO and NO 2 (nitric oxide and nitrogen dioxide). They are produced from the reaction among nitrogen, oxygen and even hydrocarbons (during combustion), especially at high temperatures.In areas of high motor vehicle traffic, such as in large cities, the amount of nitrogen oxides emitted into the atmosphere as air pollution can be significant.hey are produced from the reaction among nitrogen, oxygen and even hydrocarbons (during combustion), especially at high temperatures.

Nitrogen oxides form when fuel is burned at high temperatures, as in a combustion process. The primary sources of NOx are motor vehicles, electric utilities, and other industrial, commercial, and residential sources that burn fuels.Sources Major sources of nitrogen oxides include: â¢ Fuel combustion in power plants and automobiles. â¢ Processes used in chemical plants.Health Effects NOx causes a wide variety of health and environmental impacts because of various compounds and derivatives in the family of nitrogen oxides, including nitrogen dioxide, nitric acid, nitrous oxide, nitrates, and nitric oxide.
