Ecological risks of soil pollution in the zone of influence of the Volodymyr solid waste landfill

The article is devoted to a comprehensive study of soil pollution in the area affected by a solid waste landfill. The aim of the work is to conduct a geospatial analysis of soil pollution in the area of the Volodymyr landfill and the environmental risks of its operation. During the study, test pits were dug at three control points at different distances from the landfill and soil samples were taken at depths of 0.2, 0.4 and 0.6 m. A comprehensive assessment of the morphological and ecological-agrochemical properties of the soil was carried out, and the acidity and macroelement content at different depths were determined. Using 3D relief modelling, the main migration routes of pollutants were identified and the territory was zoned according to the degree of environmental risk. Elevated levels of phosphorus (227.7 mg/kg) and potassium (168.3 mg/kg) were found in the immediate vicinity of the landfill, with their concentrations gradually decreasing with distance from it. Hydrochemical analysis of the filtrate revealed a critical exceedance of the MPC for ammonium nitrogen (523 times), phosphate phosphorus (56.5 times) and chlorides (7.8 times). Based on the results of the study, recommendations were developed to minimise the impact of the landfill on the environment.
