Nitrogen Oxides (NOx) is a generic term for any of a number of different Oxygen compounds (known as Oxides) of Nitrogen that are given off during combustion, including Nitrogen Monoxide (NO) and Nitrogen Dioxide (NO2).


It is extremely rare for Nitrogen Monoxide (NO) or Nitrogen Dioxide (NO2) to be present without the other. Nitrogen Dioxide is toxic and, in high concentrations, strongly irritates eyes, nose, and throat, causing a cough or even pharyngalgia at times, dizziness, headaches, or nausea at times.

If a large quantity is inhaled, the lips turn blue 5-10 hours later, and cyanosis may occur in addition to pulmonary oedema. Even low concentrations generally becomes a problem and raises chronic bronchitis, gastrointestinal dysfunctions, teeth problems and sleep disturbance as chronic symptoms. In addition, it weakens the body’s immune system.

Where is it found

Today, their primary sources include automobile exhaust and factory emissions; although heating and cooking fumes do their part as well. Similar to Sulphur Dioxide, it is primarily measured continuously as part of air pollution and monitoring controls. Furthermore, it is also frequently measured at the source of industrial emissions or automobile exhaust.
