Description
The general term used for any of the nitrogen oxide gases (Nitric oxide, Nitrous oxide, Nitrogen dioxide, and others) that occur as atmospheric pollutants. Nitrogen oxides are produced by the incomplete combustion of Petroleum and Coal. They are also produced by passing air through an electric arc. Nitrogen oxides are strong nitrating and oxidizing agents that attack many types of materials, such as metals, stones, Cellulose, proteins, and dyes. Nitrogen oxides react with volatile organic compounds to form Ozone. Over 23,000 tons of nitrogen oxides were emitted as pollutants in the United States in 1994.
