NO2 is primarily released into the air from the burning of fuel as a result of emissions from cars, trucks and buses, power plants, industrial boilers, incinerators, steel mills, cement plants, and petroleum refineries.  Nitrogen oxides are also produced naturally by forest fires, grass fires, lightning, trees, bushes, grasses, and yeasts.

A high concentration of NO2 in the air can cause irritation when breathing and have adverse effects on the human respiratory system. Children, the elderly, and those with asthma are at a higher risk of the health effects of NO2.

Elemental Instruments, a division of Ohio Lumex, offers a range of nitrogen oxide analyzers that provide online, real-time measurements to control and monitor emissions and processes.

Nitrogen Oxides (NOx) are composed of a group of seven compounds. Of those compounds, nitrogen dioxide (NO2) is the only one regulated by the U.S. EPA because of its prevalence in the atmosphere generated by manmade activities. Not only is NO2 a critical air pollutant, but it can also form ozone (O3) and acid rain as it reacts in the atmosphere. Additional nitrogen oxides include nitrous acid and nitric acid (NO).
