Abstract: The article provides an analysis of the state of the problem of soil pollution with ecotoxicants. According to chemical and biological characteristics, all pollution is divided into four main types: inorganic, organic, radioactive, and bioorganic. The physical cause of the formation of anomalies in the specific electrical resistance (SER) in the zones of pollution with acid (alkali) solutions and oil products is theoretically substantiated. The analysis of the electrically conductive properties of sandy-clayey soils as a three-phase medium (solid particles – air – pore-filling liquid) made it possible to establish that highly conductive ecotoxicants based on inorganic substances and low-conductive ones, including oil and its products, are electrically contrasting. Direct calculation of the pollution factor kз is complicated by the need to know the porosity and moisture content of the soil, as well as structural and textural parameters. A set of laboratory studies was conducted on soil samples artificially polluted with ecotoxicants. A sample of clean soil (loam) of room dryness was mixed with a fixed amount of pollutant (solutions of H2SO4 acid, NaOH alkali, used motor oil) using a mixer, then placed in a measuring cell and compacted. The pollution coefficient kз was determined by the ratio of the masses of the ecotoxicant and soil. An approximate estimate of the kз value for soil samples in laboratory and natural (production) conditions, including in remote and automated modes, based on the results of electrical soundings is provided using regression dependencies for the ratio of the effective resistivity to the initial value.
