Opis:
The ecological situation in most mining regions of Ukraine is critical, and the closure of unprofitable mining enterprises, mines and cuts creates the environmental problems associated with significant changes in the geological and hydrological environment. The purpose of the work is the environmental monitoring of heavy metals in the soils in the territory of Rozdil State Mining and Chemical Enterprise (SMCE) "Sirka" at the stage of liquidation.The object of the study involves the heavy metals in soils in the territory of Rozdil SMCE "Sirka". The subject of the study is to evaluate the content of heavy metals and migration aspects in soils. In this work, the parameters of soil pollution with heavy metals were determined experimentally. On the example of Rozdil SMCE "Sirka", the main problems of the monitoring system of the territory of the mining and chemical enterprise at the stage of liquidation were proven. The influence of the mining and chemical enterprise on the state of environmental pollution (soil, water environment, and waste management status) was also assessed. The ecological balance of the territory is violated due to the fact that the elimination of negative technical manifestations of the enterprise activity was considered unprofitable for a long time. The development of monitoring techniques for man-made landscapes, along with the development of methods for diagnosing the specifics of their functioning and technologies for reclamation, is an integral part of multidisciplinary research on environmental imbalances, which is caused by the transformation of natural landscapes into man-made. The necessity of developing the information-analytical system for the monitoring of the Rozdil State Mining and Chemical Enterprise (SMCE) "Sirka" territory at the stage of liquidation was substantiated. It was established that the monitoring of the territory of the mining and chemical enterprise at the stage of liquidation will allow increasing the level of environmental safety of the territory of the enterprise and the surrounding settlements. Monitoring is one of the main stages of the liquidation and reclamation process and should be carried out at all stages of liquidation. In addition to the monitoring system in the process of liquidation and in the post-reclamation period, the liquidation project should include an environmental analysis of the enterprise activities and environmental forecasting.

Opis:
Presently, the highest level of waste generation is characterized by ferrous metallurgy enterprises, the large-tonnage wastes of which are slags of various industries. Taking into account the negative impact of slags on the environment, the limited opportunities for expanding dump volumes, as well as the depletion of sources of raw mineral raw materials, the aim of research was to develop an alternative method for the utilization of steel-smelting slags of the mining and metallurgical complex. Tthe steel smelting slag of the Novolipetsk metallurgical plant and the sewage sludge of the city water treatment station in Lipetsk were selected as the materials for the study. In the laboratory, the chemical composition of the waste was determined by means of a complex of modern analytical methods, including atomic emission spectrometry with inductively coupled plasma, X-ray fluorescence spectrometry, and atomic absorption spectrometry with electrothermal atomization. The results of the analysis enabled to assess the possibility of sharing waste as a soil additive to improve the quality of the soil. Then, under laboratory conditions, the grass mixture was grown on model soil samples with a soil additive consisting of the investigated waste with a different mass ratio. On the basis of the obtained data on seed germination, the growth of the aerial part of the biomass, the height of the leaves, and also the content of the accumulated metals in the plants, a formulation of an organomineral additive was proposed for poor soils of disturbed lands.
