A secondary pollutant is not directly emitted as such, but Digestive gases: Methane and other gases generated by the digestion of food and emitted by animals such as cattle. The methane is produced by their normal digestive process. Short-lived VOCs interact with NOx to produce high ground-level ozone in polluted environments. Try to commute a little earlier because air pollution builds up during rush hour. Major anthropogenic sources of methane include natural gas production and use, coal mining, livestock, and rice paddies.
