Peculiarities of Vertical Distribution of Aerosols and Gas Impurities in the Lake Baikal Region

V. L. Potemkin, I. V. Latysheva, V. L. Makukhin, T. G. Potemkina

With the help of a nonlinear nonstationary spatial Euler model, the processes of propagation and transformation of solid suspensions, sulfur compounds and nitrogen compounds in the Angara valley and above Baikal were investigated. Calculations were made to assess the impact of meteorological conditions on the dynamics of smoke plumes from anthropogenic sources. Strong convection of heated gases during ejection creates a large variety of aerosol cloud forms, which, when lifted, stratify, are drawn into the general wind flow and can be transported over long distances, covering the basin of Lake Baikal. Constructed maps of the distribution of pollutants near the surface of the earth and at altitude levels. Estimates of sedimentation of suspended solids on the underlying surface were made. It was found that 95 % of the coarse fraction particles (1–20 µm) are deposited on an area of 200×200 km2. The contributions of the enterprises of the Priangarie, the Baikal and Transbaikalia to the pollution of Lake Baikal by sulphates and nitrates through the atmospheric channel are calculated. The cities of Slyudyanka and Baikalsk have the greatest influence (53 and 64 %, respectively). Less impact from Irkutsk and Cheremkhovo (18 and 25 %). Transbaikalia enterprises make 29 and 21 % of the contribution. The obtained data can be used when conducting monitoring observations and making forecasts for the development of territories, taking into account local topography and climatic factors. The use of mathematical models of varying degrees of detail is promising and can simplify the preparation and conduct of fairly expensive and complex sampling of air, soil or snow when studying the effect of atmospheric emissions on the environment.
