Product of combustion from transportation and stationary sources and a major contributor to acid deposition and the formation of ground level ozone in the troposphere. 

Oxydes de l’azote

one of many chemical compounds made of different combinations of nitrogen and oxygen.

The result of photochemical reactions of nitric oxide in ambient air. It is a major component of photochemical smog, a product of combustion from transportation and stationary sources, and a major con [..]

Nitrogen oxide is formed during incineration as the nitrogen in the incineration air is oxidised. Emissions of nitrogen oxide contribute to acidification, eutrophication and "smog", and can cause direct damage to vegetation.

A criteria air pollutant. Nitrogen oxides are produced from burning fuels, including gasoline and coal. Nitrogen oxides react with volatile organic compounds (VOCs) to form ozone, the main component of urban smog. Nitrogen oxides are also a precursor pollutant that contributes to the formation of acid rain.
