Other Names

Nitrous oxide, N2O, Laughing gas


Nitrous oxide (N2O), a colorless gas, is a major greenhouse gas that absorbs infrared radiations.
Near the surface, it is naturally produced through bacteriological decomposition of organic matter. The main anthropogenic sources are from agriculture and number of industrial processes. From the troposphere it gets transported to the stratosphere. Nitrous oxide is removed mainly by the photolysis. It has a long lifetime of about 160 years. It is currently present at a level of about 330 ppb. In large amounts, it has anesthetic properties (laughing gas) and is used in the medicine.
