Nitrogen Oxides

Nitrogen oxides are a group of highly reactive gases that are composed of nitrogen and oxygen molecules. This group of gases includes nitric oxide (NO) and nitrogen dioxide (NO2), which are considered to be the two main pollutants of nitrogen oxides. Nitrogen oxides are mainly produced by high temperature combustion processes, such as those occurring in vehicles, power plants, and industrial facilities. Additionally, some natural processes, such as lightning and volcanic eruptions, also contribute to the emission of nitrogen oxides into the atmosphere. Nitrogen oxides can have significant environmental impacts, including the formation of acid rain, depletion of the ozone layer, and the production of fine particulate matter, which can have negative effects on human health. To mitigate these impacts, efforts are being made to reduce nitrogen oxide emissions through the use of cleaner fuels, improved engine technology, and other measures.
