Abstract
Quantitative chemical analysis of snow for the concentrations of water-soluble forms of Zn, Pb, Cd, Cu was carried out by means of stripping voltammetry in snow water sampled in 2019. The content of organic carbon in the sediments collected on the filter was determined using titrimetry. Calculation of liquid and solid melt runoff during the snow flood of 2019 was carried out relying on the results of chemical and analytical monitoring. Based on the previous chemical and analytical studies of the solid particles in snow cores for the content of the sorbed forms of Zn, Pb, Cd, Cu, the amount of chemical load on the channel network of the upper reach of the Ob river in the area affected by Barnaul city was calculated.
