Magnetic measurements of soil pollution in low urbanized environment
By O. MenshovSummaryThe environmental pollution by heavy metals and other dangerous to human health chemicals is one of the biggest threats and challenges for the sustainable functioning of the European cities. In our study we try to assess the general trends for the pollution level of slightly impacted urban environment based on energy-efficient technology. The implementation of this approach is proposed on the example of Truskavets (Ukraine). The ultimate goal is to produce data of the pollution with the magnetic measurements of soil. The results can be used by environmental management companies, centers of environmental monitoring of cities, or geophysical observatories. Low cost, non-destructive and rapid magnetic techniques are promising in monitoring soil and air pollution both at the highly anthropogenic impacted areas and at the slightly urbanized sites. The magnetic mineralogical analyzes such as thermomagnetic studies, hysteresis and remanence acquisition, ARM, and Sratio identified the magnetite-like phase as the main magnetic mineral responsible for the magnetic enchantments in polluted soils. At the same time non polluted soils may contain the small amount of the single domain particles and the high coercivity minerals such as haematite and goethite.

To the soil magnetic susceptibility application in modern soil science
Authors O. Kruglov and O. MenshovSummaryThe agricultural science has a big challenge in terms of the eligibility to sustainable agriculture. The separation of lands to the agroindustrial groups in this case doesn’t provide full information support. The main objective for achieving this goal is to account the internal structure of agricultural landscapes. The priority is to study the natural substructure at artificially restricted areas, crop rotation areas or pastures. The main factor of degradation of the southern forest-steppe and steppe of northern left bank of Ukraine is water erosion. At the same time the deflationary processes increase in the East of Ukraine. The purpose of the study is the consideration of the case study at the area of left bank Forest-Steppe. We study magnetic methods assessment in zoning the modern agricultural landscapes. We conclude the possibility to use the magnetic susceptibility as parameter which could replace the determination of humus content within large areas, large-scale soil survey, environmental studies, land surveying, creating sustainable agricultural landscapes. The magnetic susceptibility measurement is much lower cost than the humus content determination if the same sampling grid. The prospective of the soil magnetic susceptibility application in soil erosion study is the combination with other physical and chemical research.

Subsurface Geologic Structures Investigation using Geophysical Methods at Hydroelectric Power Plant (HPP) Territory
Authors S. Vyzhva, V. Onyshchuk, I. Onyshchuk and M. RevaSummaryThe article discusses the informativeness of advanced geophysical studies, according to which the small-block structure of the geological section of the territory was identified. At the base of the geological section, are lying the Precambrian crystalline rocks, which are significantly different in the magnitude of the resistivity, from 780 to 50000 Ohm, and by the values of the velocity of refraction waves from 2.7 to 7.0 km/s.
A wide range of changes in the geophysical characteristics of the basement rocks indicates significant changes in the degree of fracturing and weathering of crystalline rocks, which should be taken into account when drawing up a master plan for the location of HPP facilities.

Evaluation of atmospheric dust pollution in Kyiv, according to absorption spectral analysis and magnetic susceptibility measurements of air filters
Authors I. Tsiupa, K. Bondar, A. Korol and I. StakhivSummarySystematic studies of magnetic susceptibility of air filters Xf from the air-sampling stations of the Central Geophysical Observatory SSES revealed consistently high values on stations №№7, 11, 20, i.e., Peremogy av. 98/2, the Besarabian and Demiivska Squares. In the last two stations, as well as on №9 Kaunasska st.10a and №4 Borodin st. 2 we received significant correlation coefficients between Xf and content of Fe, Mn, Cu. These three elements form the basic anthropogenic geochemical association which pollutes the air in Kyiv. It is demonstrated that utilization of Xf for evaluating and modeling of air HM pollution is not possible in areas of anthropogenic geochemical anomalies for the corresponding elements, where high dispersion Xf and/or HM is observed.

Magnetic minerals and heavy metals content of industrial dusts and polluted topsoil of Zaporizhzhya (Ukraine)
Authors K.M. Bondar, I.V. Tsiupa, H.B. Kozhemiakin, I.V. Kuraieva and Yu.Yu. VoitiukSummaryThe anthropogenic ferromagnetic minerals and heavy metals (HM) content is considered in atmospheric particulate matter emissions (dusts) of Zaporizhzhya industrial complex and in city topsoil. The work cycle of Zaporizhzhya industries involves the processes of iron ore agglomeration, the production of cast iron and steel smelting in open-hearth and electric steelmaking furnaces. Measurements of χ, χfd(%), SIRM, MS, HC, HCR, content of Cd, Pb, Cu, Zn, Mn, Ni were performed on 4 dusts and 60 soil samples, series of selected samples undergo thermal experiments of χ behavior in low and high temperatures. The processes of iron ore agglomeration cause emission of dusts containing MD stoichiometric magnetite. Emission of high-temperature technological processes as production of cast iron and steel smelting cause emission of dusts containing PSD titanomaghemite and titanomagnetite. PMs containing industry-derived magnetic minerals are spread by air flow and cause magnetic and HM enhancement in soils.

The impact of geological environment on pipeline systems in the area of stray current
Authors Y.M. Hloba, R.M. Hloba and O.V. DanylovSummaryIt is proposed to apply a set of geophysical methods to engineering surveys when designing and operating linear underground constructions of pipeline transport. The study allows for identifying the area’s best fitting for laying and operating the pipeline transport system. The paper provides a complex of geophysical methods to guarantee safety standards on the pipeline transport systems when affected by natural and anthropogenic hazards.
Electrical methods, such as symmetrical electrical profiling, gradient potential method and self potential method, were used to identify possible areas of corrosion on the underground oil pipeline «Kremenchuk-Herson». Research the effect of stray current on steel pipe. The low apparent resistivity and high negative spontaneous potential values are indicated that the soil is very corrosive and there is the possibility of the pipeline failure in the future. Electrical geophysical investigations along buried pipelines should be undertaken for the early detection and prevention of pipeline failure with its negative environmental and economic consequences.

Geological sources of magnetic and radon anomalies on the territory of Kyiv
Authors P.I. Yatsevskyi and M.I. OrlyukSummaryThe report discusses geological sources of radon anomalies in Kyiv and its relationship with the magnetic field. Radon and other radioactive gases have dominant role in total level of the contamination inside buildings and in the air of soils. Identification and evaluation of radon areas is an urgent task to study its effects on human health. Magnetic survey can be used as indirect method to estimate radon levels in the surface part of the crust and in the airspace because measurements of radon concentration have point character. Acid igneous rocks of the basement (characterized by a weak magnetization ) are sources of radon anomalies. This connection is a physical and geological justification for such phenomenon. Consequently, the radon anomalies will correlate with the negative anomalies of the geomagnetic field near faults and fracture zones.
The result obtained can be used within the Ukrainian shield (acid or alkaline rocks, fractures zones and faults should be located in the investigation area) for building predictive models of radon hazard according to magnetic survey.
