| nitrous oxide |
Colorless gas, formula N 2 O, released by bacterial activity at the earth's surface. It has an atmospheric lifetime of about 160 years and is currently present at a level of about 330 ppb. Its atmospheric significance is that it is transported into the stratosphere, where its reaction with excited oxygen atoms (O 1 D) is the major source of active nitrogen; it is also a major greenhouse gas. In large amounts, it has anesthetic properties (laughing gas).
