What are Nitrogen Oxides?

Nitrogen Oxides are gases that are composed of nitrogen and oxygen. Two of the most toxicologically significant of the nitrogen oxides are nitric oxide and nitrogen dioxide. Nitrogen oxides are released into the air from the exhaust of motor vehicles, the burning of coal, oil or natural gas, and during processes such as arc welding, electroplating, engraving, and dynamite blasting. Concentrations also increase by burning wood or kerosene, cigarettes, and gas stoves. They are produced commercially by reacting nitric acid with metals or cellulose. Nitrogen oxides are used in the production of nitric acid, lacquers, dyes, and rocket fuels.

Health Risks

Exposure to high levels of nitrogen oxides can damage the airways, causing irritation, coughing, shortness of breath, and even fluid buildup in the lungs. Inhalation can also cause tiredness and nausea. Contact with the skin and eyes causes irritation and burns. Exposure to high levels of nitrogen oxides can cause rapid burning, spasms, and swelling of throat and upper respiratory tract. Extreme cases can lead to reduced oxygenation, buildup of fluid in the lungs, and death.
