Pyruvic acid in the boreal forest : gas-phase mixing ratios and impact on radical chemistry [PDF]

open access: yesAtmospheric Chemistry and Physics, 2020
Pyruvic acid (CH3C(O)C(O)OH, 2-oxopropanoic acid) is an organic acid of biogenic origin that plays a crucial role in plant metabolism, is present in tropospheric air in both gas-phase and aerosol-phase, and is implicated in the formation of secondary ...
