About Non-Methane Hydrocarbons
- These are trace atmospheric constituents which includes ethane, ethene, propane, propene, and isoprene
- These are a group of reactive gases emitted from fuel use, vehicles, and other human activities that play a key role in forming ozone and secondary aerosols.
- Production: They are primarily produced from terrestrial sources, with some contribution from marine environments, and exhibit distinct production processes influenced by environmental factors.
- They play a significant role in controlling ozone concentrations and serving as a sink for hydroxyl radicals.
- They are vital precursors for the photochemical formation of tropospheric ozone and secondary organic aerosols (SOA)
- Impact: It is important to trace them and evaluate their implications for regional air quality and potential impacts on human health.
