- <p class="MsoNormal"><span>A comprehensive study was conducted to examine the influence of various types of anti-icing agents (sand-salt mixture and the commercial product "Aquais Econom") on the physicochemical properties of soils in the Vladimir urban ecosystem with varying levels of anthropogenic load. It was found that the use of anti-icing agents leads to a significant chemical load on the snow cover, expressed in a multiple excess of background concentrations of chlorides, calcium, and magnesium. The soils showed the development of technogenic salinization of the chloride-sodium type with a total toxic salt content of 10.25–14.76 mg-eq/kg, which corresponds to the category of highly saline soils, and a sharp alkalization (pH 8.01–8.61). Degradation of the physical properties of urban soils, manifested in sandification and deterioration of the aggregate composition, was proven. Despite an increase in the content of mobile forms of phosphorus and potassium, a decrease in the content of organic matter was noted. Bioassays using garden cress (Lepidium sativum L.) revealed moderate to high phytotoxicity of meltwater, most pronounced with the "Akvays Econom" reagent. The study results demonstrate the complex degradation of urban soils under the influence of deicing agents and substantiate the need to revise winter maintenance practices in urban areas.</span></p>
