Parameters of the distribution of fluorine, sulfur, and sodium in the Baikal region with the production of primary aluminum

Abstract

The parameters of the distribution of fluorine, sodium, and sulfate ions in the environment surrounding the Baikal region are considered using Bratsk as an example. Their contents in atmospheric precipitation (rain, snow, aerosol, and snow cover) and the intensity of load on the territory in 2008–2009 are determined. The results are obtained based on snow-chemical recording and sampling single specimens of atmospheric fallout and aerosols. A map of pollution of the snow cover with water-soluble fluorine is presented and the power of the source of emission of hydrogen fluoride is evaluated. It is suggested to decrease the emissions of HF by applying lithium additives in the form of fluorine-containing lithium salts obtained with the use of lithium brines of Eastern Siberia.
