ABSTRACT

ABSTRACT: Diesel soot, an important contributor to atmospheric aerosols, consists of a complex mixture of compounds. However, a very limited knowledge on the organic composition of aerosol and the water soluble fraction exists. A considerable portion of polar (oxygenated) organic compounds remained unanalysed, and additional analyses are needed to identify the polar compounds. Column fractionation of a diesel soot results in the obtaining of a methanol-soluble polar fraction enriched in aromatic polycarboxylic acids. This analysis provides a comprehensive dataset and important clues for solving the chemical nature of the polar (oxygenated) aerosol fraction and for identifying the polar compounds deposited on the surfaces of historic monuments.
