Abstract
The 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.
