Abstract:

To study the processes of formation of acid aerosols in the atmosphere, we apply a complex approach, which combines the field measurements of the concentrations of reactive atmospheric admixtures with the laboratory modeling and numerical simulation of the photochemical mechanism of reactions and the aerosol-forming capability of some components (aldehydes, sulfur dioxide, ozone, alkanes). The data are obtained using high-sensitivity methods for analysis of secondary transformations of substances in the atmosphere and in the laboratory modeling. To interpret the results, we employ information databases on the kinetics of atmospheric reactions at the level of elementary chemical stages. The efficiency of this approach is demonstrated for the purpose of environmental forecast for the formation of acid components of atmospheric aerosol considered as an example.
