<onlyinclude>'''Nitrogen''' ('''N''') is the 7th [[element]] on the [[periodic table of elements|periodic table]].

Nitrogen is used in a variety of ways in both its [[gas]]eous and [[liquid]] form, however nitrogen is also a major component of the group of [[pollutant]]s known collectively as [[nitrogen oxide]]s or NOx.

==Uses==
Nitrogen is used in almost all pharmacological drugs, and is found in nitrous oxide - an anesthetic. As well, liquid nitrogen is available as a relatively inexpensive cryogenic liquid used to preserve biological specimen and conduct low [[temperature]] scientific experiments.<ref name=uses>Uses Of. (August 4, 2015). ''Uses of Nitrogen'' [Online]. Available http://www.usesof.net/uses-of-nitrogen.html</ref>

As well, another major use of nitrogen is in the production of [[ammonia]] (NH3) in a process known as the Haber process. This ammonia is then used to create fertilizers, explosives, and nitric acid.<ref name=jeff/>

Finally, nitrogen gas is inert (meaning that it is largely unreactive) and thus it is used as a productive shield in the production of [[semiconductor]]s, as well as in some welding and soldering operations. Oil companies also use high [[pressure]] nitrogen to force [[crude oil]] out from the ground.<ref name=jeff/>

==Nitrogen Oxides==
:: [[NOx| ''main article'']]
Nitrogen oxides are poisonous, highly reactive, and generally brown in colour. They form when [[fuel]] is burned at high temperatures. Nitrogen oxides are emitted by vehicles as well as industrial sources such as [[power plant]]s, industrial boilers, cement kilns, and [[turbine]]s. Nitrogen oxides have problematic chemical reactions in the atmosphere with [[volatile organic compound]]s. These reactions produce [[smog]] on hot summer days.<ref name="RE1">US EPA. (July 21, 2015). ''Nitrogen Oxides'' [Online]. Available: http://www.epa.gov/region1/airquality/nox.html</ref> The two major nitrogen oxides that exist are NO and NO2

Nitrogen oxides are harmful to both people and the [[environment]]. To humans, exposure to nitrogen oxides can cause increased incidence of respiratory illness and infection. Longer-term exposure can lead to actual changes in the lungs.<ref name="RE3">Clean Air Trust. (July 21, 2015). ''Air Pollution - Nitrogen Oxides'' [Online]. Available: http://www.cleanairtrust.org/nitrogendioxide.html</ref> This is because nitrogen dioxide, a major nitrogen oxide, is an irritant that is a main component of smog. As well, in the atmosphere nitrogen oxides can be transformed into [[ozone]] - which has its own adverse health effects.
