GC: n
CT: NOx is a generic term for the various nitrogen oxides produced during combustion.
They are believed to aggravate asthmatic conditions, react with the oxygen in the air to produce ozone, which is also an irritant and eventually form nitric acid when dissolved in water.
When dissolved in atmospheric moisture the result can be acid rain which can damage both trees and entire forest ecosystems.

N: 1. nitrogen (n): From French nitrogène. Coined in by French chemist Jean Antoine Chaptal (1756-1832), from the combination form of Greek nitron (sodium carbonate) and French gène (producing). The gas was identified in part by analysis of nitre.
oxide (n): From French oxide (1787), coined by G. de Morveau and A. Lavoisier from ox(ygène) and (ac)ide (acid). Compound of oxygen with another element.
2. Generic term for the various nitrogen oxides produced during combustion.
3. Any of several oxides of nitrogen most of which are produced in combustion and are considered to be atmospheric pollutants: as nitric oxide, nitrogen dioxide and nitrous oxide.
4. Two of the most common nitrogen oxides are nitric oxide and nitrogen dioxide. The chemical formula for nitric oxide is NO; for nitrogen dioxide, it is NO2. Nitrous oxide, N2O, is a greenhouse gas that contributes to climate change.
5. You can be exposed to nitrogen oxides outdoors by breathing air that contains it, especially if you live near a coal-burning electric power plant or areas with heavy motor vehicle traffic. You can be exposed to higher levels if air pollution and smog levels are high.
- You can be exposed at home if you burn wood or use a kerosene heater or gas stove.
- You can be exposed at home or at work, indoors or outdoors, through smoking cigarettes or breathing second-hand cigarette smoke.
- You can be exposed at work if you work in a facility that produces nitric acid, explosives such as dynamite and TNT, or welded metals.
