Nitrogen oxides (NO x = NO + NO2) are a primary component of air pollutiona leading cause of premature death in humans and biodiversity declines worldwide. Although regulatory policies in California have successfully limited transportation sources of NO x pollution, several of the United States worstair quality districts remain in rural regions of the state.United States Office of Air Quality EPA 456/F-99-006R China Nitrogen Concentrator with CeWHAT IS A NITROGEN OXIDE? Diatomic molecular nitrogen (N2) is a relatively inert gas that makes up about 80% of the air we breathe. However, the chemical element nitrogen (N), as a single atom, can be reactive and have ionization levels (referred to as valence states) from plus one to plus five. Thus nitrogen can form several different oxides.
