Content analysis of salts and suspended substances in snow and thawed water

Abstract

Abstract The research article discusses the chemical composition of the anti-icing reagents, and presents the results of studies to determine the content of suspended solids and salts in the snow at different intervals from the edge of the roadside on the main streets of Izhevsk. The following dependence was revealed – a decrease in the concentration of salts and suspended substances in snow samples with distance from the edge of the roadway. The concentration of salts in the samples at different distances from the edge of the roads reached 5822 mg/l. The concentration of suspended solids in snow samples reached 13470 mg/l. It was found that when taking samples of snow at a distance of 25 meters from the edge of the roadway, there is an excess of the concentrations of salts and suspended solids in the snow, the values of the maximum permissible concentration for admission to surface water bodies.
