NMVOC

From Wikipedia, the free encyclopedia

NMVOC is the abbreviation for non-methane volatile organic compounds.

It is a generic term for a large variety of chemically different compounds, like for example, benzene, ethanol, formaldehyde, cyclohexane, 1,1,1-trichloroethane or acetone. Essentially, NMVOCs are identical to VOCs, but with methane excluded.

Sometimes NMVOC is also used as a sum parameter for emissions, where all NMVOC emissions are added up per weight into one figure. In absence of more detailed data, this can be a very coarse parameter for pollution, e.g. for summer smog or indoor air pollution.
