Research Abstract |
Concentrations and structural characteristics of humic-like substances in atmospheric aerosols, which are fractionated into water-soluble, humic acid-like, and fulvic acid-like fractions, are analyzed. Molecular size distributions and proportions of carbon species of the humic-like substances are similar to those of humic substances isolated from soil and water. However, chemical compositions of the humic-like substances are differed from those of the humic substances, suggesting the different origins and generation pathways of these substances.
