Resumo

THE ATMOSPHERE.A general overview about the ambient levels of low molecular weight carboxylic acids and their possible emission sources, as well as the implication of them in the atmosphere is presented.Carboxylic acids are considered to be one of the dominant classes of organic compounds found in the atmosphere in a variety of phases, such as in rainwater, snow and ice, on aerosol particles and gas phase.They may be originated from biogenic and anthropogenic direct emissions and by photochemical reaction in situ.Emission sources and formation mechanisms of organic acids in the atmosphere are discussed.
