Non-methane volatile organic compound

[1] NMVOCs include a large variety of chemically different compounds, such as benzene, ethanol, formaldehyde, cyclohexane, 1,1,1-trichloroethane and acetone.

[2] Essentially, NMVOCs are identical to volatile organic compounds (VOCs), but with methane excluded.

[1] NMVOCs is an umbrella term which encompasses all speciated and oxygenated biogenic, anthropogenic, and pyrogenic organic molecules present in the atmosphere, minus the contribution of methane.

[6] The aggregation of these compounds and their collective properties are easier to study than the individual components.

[8] These atmospherically important NMVOCs include compounds such as terpenoids, hexenals, alkenes, aldehydes, organic acids, alcohols, ketones, and alkanes).

[8] Major geogenic sources of NMVOCs include volcanism and seepage resulting from natural gas.

[9] In the European Database for Global Atmospheric Research (EDGAR), anthropogenic sources of NMVOCs are divided into the following categories:[4] EDGAR measures that in 2015, the amount of NMVOCS from the six most contributing sectors (agriculture, power industry, waste, buildings, transport, and other industrial combustion) was 1.2*108 tons.
