Biogenic compounds
WebThe term biogenic volatile organic compounds (biogenic VOCs) includes organic atmospheric trace gases other than carbon dioxide and monoxide. Focusing on hy-drocarbons but excluding methane, the term nonmethane hydrocarbons (NMHCs) is used, while VOCs without methane are termed nonmethane VOCs (NMVOCs). WebThis overview compiles the actual knowledge of the biogenic emissions of some volatile organic compounds (VOCs), i.e., isoprene, terpenes, …
