Nitrous oxide (dinitrogen oxide or dinitrogen monoxide), ... Soils under natural vegetation are an important source of nitrous oxide, accounting for 60% of all ...
Though nitrous oxide is emitted during its application, it is then reacted in atmosphere to form nitrogen oxides. This third source is attributed to the reaction of atmospheric nitrogen, N 2, with radicals such as C, CH, and CH 2 fragments derived from fuel, [26] rather than thermal or fuel processes.
Some wetlands are a significant source of methane emissions [6] [7] and some are also emitters of nitrous oxide. [8] [9] Nitrous oxide is a greenhouse gas with a global warming potential 300 times that of carbon dioxide and is the dominant ozone-depleting substance emitted in the 21st century. [10] Wetlands can also act as a sink for greenhouse ...
The major anthropogenic (human origin) sources of greenhouse gases are carbon dioxide (CO 2), nitrous oxide (N 2 O ), methane and three groups of fluorinated gases ( sulfur hexafluoride ( SF 6 ), hydrofluorocarbons (HFCs) and perfluorocarbons (PFCs, sulphur hexafluoride (SF 6 ), and nitrogen trifluoride (NF 3 )).

Agricultural emissions of nitrous oxide make up 6% of the United States' greenhouse gas emissions; they have increased in concentration by 30% since 1980. [76] While 6% may appear to be a small contribution, nitrous oxide is 300 times more effective at trapping heat per pound than carbon dioxide and has a residence time of around 120 years. [76]
Dr. Arash Motamed, an anesthesiologist at USC's Keck Hospital, said nitrous oxide has historically been used to help get people unconscious but recreational use of the gas can lead to health problems.
Nitrous oxide (N 2 O), commonly referred to as laughing gas, along with various street names, is an inert gas which can induce euphoria, dissociation, hallucinogenic states of mind, and relaxation when inhaled. [1] Nitrous oxide has no acute biochemical or cellular toxicity and is not metabolized in humans or other mammals.
