“…Studies have shown that magnesium chloride-based agents have less effect on higher plants and soil microorganisms compared to calcium and sodium chlorides. [1,2] Due to incomplete purification of sodium chloride from impurities, the arsenic contained in the technical salt enters the soil. As a carcinogen, arsenic can have an extremely negative impact on soil microflora in the long term.…”

The problem of the influence of de-icing chemicals on the geological environment of urban landscapes is raised. In connection with the increase in passenger traffic and the load on the road network, the problem of using a deicing chemical (DIC) is acute. DICs adversely affect the environment, getting into the soil and groundwater, increasing their aggressiveness. In particular, chemicals affect the rocks of the base structures, which are represented by minerals of the carbonate class. The impact leads to leaching and dissolution of carbonates and the formation of karst cavities, which, when enlarged, can lead to subsidence of the surface, often to failures and, as a result, to deformations of structures. They cope well with the task of ensuring road safety by melting ice at low temperatures, but this decision also has a number of negative consequences for urban areas. It is important that these salt mixtures, in addition to their primary task of chemical melting of ice, continue to enter into chemical reactions with environmental components: soils, base rocks, groundwater, which causes significant harm to the urban environment. The general ecological situation of the city is deteriorating, and there is a risk of developing dangerous geological processes.

“…In winter, roads, pavements, and adjacent areas maintenance to ensure practicability and safety involves snow removal by means of various de-icing agents. Two main ways are used globally for de-icing: mechanical way (sand, crushed stone, rock crumbs) to increase friction, and chemical way (reagents containing Na, K, Mg salts with various additives) [GERASIMOV, CHUGUNOVA 2015;XU et al 2021]. In Canada only, about 5000.00 Gg of road salt are used annually in China -600.00 Gg in year, in Sweden -150.00 Gg in year [ANTONSON et al 2021;RØDLAND et al 2020].…”

“…In Russian cities, excessive use of de-icing agents on pavements and pedestrian paths, as well as storage of contaminated snow from roadways and residential parking lots on lawns, has been widespread in recent years [GERASIMOV, CHUGUNOVA 2015;MALYSHEVA et al 2018]. In Perm, snow and soil cover of roadside lawns and squares contain significant concentrations of Ni, As, Zn, Cu, Co, Pb, W, Cr, and Sb [VORONCHIKHINA et al 2014].…”

Atmospheric deposition, vehicular transportation and de-icing agents are major sources polluted snow in urban. This study investigates the current trace elements concentrations of snow and de-icing using ICP-MS, and phytotoxicity using three vascular plants in snow. The study assesses the contamination, classification and phytotoxicity of snow quality removed from roads of residential areas and piled on children's playgrounds in residential territories. The research found that according to Russian environmental quality standard for water has been identified the exceeding trace elements in snow by W, Se, Mn, Cu, V, Mo, Ni and Zn. The pollution indices (PLI, CF and Zc) were identified pollution level of snow piles from moderate contamination to very high contamination. Based on average germination index values for Sinapis alba L., Lepidium sativum L., and Triticum aestivum L., the degree of inhibition in snow piles varied from no inhibition to strong inhibition. The trace elements content in de-icing "Galit А" and salt sand mix are defined in the following descending order: Zn > Mn > Ba > V > Rb > Sr and Mn > Ba > Cr > V > Sr > Ni, respectively. High concentrations of trace elements in snow piles are a source of environmental pollution. To prevent snow storage and disposal in residential areas should be involved in future studies of environmental pollution and circular economy, so that environmental managers can reduce threats to the environment and public health, as well as initiate circular economy projects in urban areas.
