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. 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.
Industrial processes such as metals processing and chemical manufacturing also emit carbon monoxide into the atmosphere [5]. : Nitrogen oxides are a group of gasses that include nitrogen dioxide, nitrous acid, and nitric acid.Nitrogen dioxide is the most notable, being extensively released by vehicles and other fossil fuel combustion in power plants and industrial processes. Sulfur dioxide is one area where the main emitters are industrial processes, with power plants (see: coal-burning) releasing 66% and other industrial processes releasing 29%. Sulfur dioxide is also linked to respiratory problems and plant damage and is one of the main components of smog.
