What is Nitrogen Dioxide?
Nitrogen Dioxide, or NO2, is a reddish-brown gas. In the environment, Nitrogen Dioxide can also react with oxygen, ammonia and moisture in the air to form particulate matter and ground-level ozone. Sometimes, Nitrogen Dioxide (NO2) and Nitric Oxide (NO) are referred to as Nitric Oxides (NOx).
Where does Nitrogen Dioxide come from?
Nitrogen Dioxide is most commonly produced by human activity, including motor vehicle exhaust, power generation and industrial combustion.
What are the health effects of Nitrogen Dioxide?
Nitrogen Dioxide is hazardous to human health in part because Nitrogen Dioxide can lead to the formation of other air pollutants, including particulate matter and ground-level ozone. Exposure to Nitrogen Dioxide is also hazardous to human health as inhalation of Nitrogen Dioxide may exacerbate asthma or other respiratory diseases, leading to wheezing and difficulty breathing. Longer-term exposure to Nitrogen Dioxide may contribute to increased susceptibility of respiratory infections as well as the development of asthma.
