Abstract:

The results of 1998-2002 studies of the chemical composition of atmospheric precipitation sampled at monitoring sites in the Baikal region (Irkutsk, Listvyanka, and Mondy) are considered. It is shown that wet precipitation in Listvyanka is most acidified. Atmospheric fluxes of major ions on the underlying surface of the territory studied are calculated. In the southern region of Lake Baikal, the atmospheric fluxes of sulfates and nitrates are calculated using a mathematical model based on numerical solution of the spatial nonlinear non-steady-state semi-empirical equation of turbulent diffusion of admixtures. At the Irkutsk and Listvyanka sites, the order of magnitude of the computer-simulated flux estimate corresponds to that calculated from the experimental data.
