Basic physical and chemical parameters of snow cover the territory of the Ile river delta

Abstract

In this work, for the first time, a physicochemical assessment of the parameters of snow cover based on their chemical composition for the territory of the Ile River delta is given. The physicochemical properties of the snow cover from the moment of its occurrence under the influence of air temperature, humidity, own weight, wind, solar radiation, as well as technogenic impact are constantly changing. Hydrometeorological conditions and orographic features of the location play a significant role, contributing to the accumulation of pollutants in the snow cover. Chemical analyzes were performed for the following parameters: pH, organic substances by permanganate oxidizability, suspended matter and mineralization. According to the preliminary results of the assessment of the physicochemical parameters of the snow cover, some pollution was found in the central zone, which are characterized by the maximum content of solid particles and the mineralization of the snow cover.
