What is Nitrogen Oxide?
The nitric oxide (NO) molecule is quite reactive and unstable. In ambient air, it reacts with oxygen to form the toxic nitrogen dioxide (NO2).
Where does Nitrogen Oxide come from?
Nitrogen oxide is mainly an unwanted by-product of fuel combustion at high temperatures. Cars and power plants are the main sources of nitrogen oxide.
What are the effects of Nitrogen Oxide?
Nitrogen oxide causes a multitude of symptoms, primarily in the lungs but also in other organs such as the spleen and liver. Additionally, nitrogen oxide is jointly responsible for acidification and over-fertilisation of soil and water. Gaseous nitrogen oxide may become particulate ammonium nitrate. This contributes to large-scale PM (PM2.5, PM10) pollution. During the summer, nitrogen oxide and hydrocarbons cause formation of ground-level ozone and destruction of the ozone layer.
