For the design foundation, it is important to know not only the structure and load of the building, but also soils properties in the subsoil. Ignoring soil properties may result in an incorrect design of foundation, which may later cause a failure in building structure, because generally known foundations function is to transfer load effects into the ground. In smaller buildings, an engineeringgeological survey is not usually carried out, but basic data on the territory is obtained from archive reports.
The problem of permanent and prolonged pollution of soils by various kinds of pollutants, in particular heavy metals, was analyzed. Experimental investigations of penetration of copper sulfate into a vertical soil profile have been carried out. The adsorption capacity of the sandy environment of copper sulfate
was experimentally determined.
The paper is focused on the research of migration process of heavy metals in the soil environment in the area of phosphogypsum storage in Sumy region. In the profile of the gray forest soils the corresponding genetic horizons were identified. The various structures of compounds containing heavy metals were detected in the samples by the diffractometric analysis. The increased gross content of lead in comparison with the background concentration in allocated humus and illuvial horizons has been determined.
The paper presents assessment of the impact of Sumy CHP when pollutants come into soils with atmospheric precipitation and filtration from the area of the ash and slug dump. Samples of snow were tested for the content of heavy metals and ash particles. Soil samples were tested for the content of heavy metals. The conducted research showed a high degree of soil contamination in the area of Sumy CHP influence.
The problem of penetration of nitrogen fertilizers in the soil is analyzed. The influence of adsorption process on the rate of transfer of fertilizers in the vertical profile of the soil is determined. Experimental researches of adsorption properties of soil environment on the base of absorption of calcium nitrate by soil are done. Проаналізовано проблему проникнення азотних добрив вглиб ґрунту. Визначено вплив процесу адсорбції на швидкість перенесення добрив по вертикальному профілю ґрунту.
The temperature impact on the rocks is the cause of additional stress and strain on them and also phase transformations (freezing and thawing) of the pore fluid. In writing this article aim was to develop the experimental data needed for the development of methodic, directed at determining the temperature fields in rocks, in which are arranged the collectors of heat pumps. Identified and analyzed, and the impact of additional load on the ground bases and foundations, which are reservoirs of groundwater heat pumps.
Purpose. At this stage of our research we study the information content of soil magnetism addressing the environmental, soil science and exploration objectives. This requires the magnetic properties data of unmodified soils at the territories of hydrocarbons prospecting, soil erosion, environmental pollution. We have collected significant soil magnetism data bank in Ukraine. At the same time the mountain-forest soils were generally not studied and poorly understood. Methods.
The analysis and genetic-morphological evaluation of existing classifications reconstruction soil, which will allow to significantly improve their future in the light of modern teaching approaches. This should draw attention to the terminology of certain taxonomic units used in the classification of industrial soil.
There are analyzed the current problems of monitoring soil Ukraine and outlined specific measures for its improvement taking into account domestic and foreign experience.
This review covers the main agents used for in situ and ex situ chemical oxidation of organic contaminants particularly oil products, in soil and water environments. Among them there are hydrogen peroxide, permanganate salts, ozone and sodium persulfate. The fields of application, as well as benefits and disadvantages of the mentioned agents use were described.
