Eduion and Outreach

Nitrous oxide (N 2 O) is a colorless, nonflammable gas with a sweetish odor, commonly known as "laughing gas", and sometimes used as an anesthetic. Nitrous oxide is naturally produced in the oceans and in rainforests. Manmade sources of nitrous oxide include the use of fertilizers in agriculture, nylon and nitric acid production, cars with alytic converters and the burning of organic matter.

Climate Program Office NOAA Nitrogen As a Pollutant in the Atmosphere. Nitrogen dioxide (NO2) is a gas that occurs naturally in our atmosphere, but in concentrations very low as compared to oxygen (O2) and nitrogen (N2). NO2 is also common pollutant produced primarily during the combustion of gasoline in vehicle engines and coal in power plants.
