CO
Carbon monoxide is formed from the incomplete combustion of coal, gasoline, and other hydrocarbons.
In the atmosphere, it has a lifetime of a few weeks, limited by its reaction with OH; consequently, it can be transported to long distances from its source regions, which are areas of high (particularly gasoline powered) motor vehicle usage.
The introduction of catalytic converters has greatly reduced CO levels in many nations; typical levels range from 40 ppb (remote polar regions), 1oo ppb (midlatitude marine/continental background) to 1-10 ppm in highly polluted en, such as Mexico City.
