Abstract
The comparative analysis of the chemical composition of water- and acid-soluble fractions in dry deposits is performed; the ratio of submicron and coarse phases in surface aerosols is assessed and their mineral and material composition are studied for the background region of Tom-Ob interfluve with use of the scanning submicroscopy. Distinctions in the ratios of metals in the water- and acid-soluble fractions are revealed. It is suggested that water-soluble compounds generally form the submicron fraction, and acid-soluble compounds, the coarse fraction.
