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.

Opis:
Effects of the stored dust-like zinc and iron containing wastes of the mining and processing industry consist of the loss of valuable components and environmental pollution. Thus, the goals of the research were to analyse ecological conditions under the technogenic impact at the waste storage site and to study transformations of the stored dust-like zinc and iron containing wastes in the active supergene zone. Materials are based on the physical laboratory-modelled infiltration of the atmospheric precipitation waters through the zinc and iron containing wastes. Methods include systematically- structured analysis of wastes and disposal site and laboratory techniques (X-ray fluorescence and atomic emission spectrometry). On the basis of laboratory research and field observations of the environmental components in the impact area of the storage of dust-like zinc and iron containing wastes, the article describes regularities of formation of hydrogeochemical halos of contamination by heavy metals and iron. The results also include the description of changes in physico-chemical groundwater composition under the storage area.
