“…The following parameters were determined: humidity, pH, organic matter content, basic biogenic elements (phosphorus, potassium, nitrogen), as well as trace elements and heavy metals. The detailed results of the analysis are presented in (Shkvirko et al, 2018), it was reported that sludge contains a significant amount of basic biogenic elements (N -3.56; P -1.6; K -0.3%), macroand microelements, as well as the available content of the organic component (23,8%), which can provide nutrients to most plants; the content of available heavy metals forms in the test samples did not exceed the MPC; neutral acidity of the medium should not have an inhibitory effect on plant growth and development.…”

The article deals with the main methods of nutrient removal from wastewater, as well as presents promising technologies and techniques. Struvite was characterized by a complex phosphorus fertilizer. The influence of struvite on the processes of germination of cultivated plants was investigated. The possibility of creating a growth substrate as an inexpensive and effective alternative to the disposal of the man-made wastes that contain an organic component was identified. The composition of the growth substrate was selected to ensure its functional properties. The growth substrate was tested by bioindication. Subsequently, the modification of the substrate by adding natural sorbents.

“…The planned investigation of variations in the bioavailable forms of heavy metals in argillites separately from argillites that have been affected by thermal effects will provide deeper insight into the processes of the geochemical transformations of such rocks and extend the results to other coal-mining dumps by making appropriate recalculations based on the ratios between the main dump rocks. The exploration of changes in heavy metal contents and bioavailability before and after rock combustion will create a scientific basis for utilizing waste heap rocks, recultivating disturbed areas [21][22][23], and optimizing coal mining and coal preparation [24][25][26][27].…”

For effective waste management of mining industries is important to investigate their physical and mineralogical changes. For this purpose, X-raydiffraction (XRD), thermogravimetry (TG), derivative thermogravimetry (DTG), and differential thermal analysis (DTA) methods were used. Changes in the contents of mobile forms of heavy metals in rocks were investigated using an acetate-ammonium buffer solution with a pH of 4.8 after burning rocks at a temperature of 800–850°C. The obtained data indicated the significant role of the mineral composition in the thermal behavior of the rock samples and the subsequent influence of the thermal processes on the changes in the bioavailability of heavy metals.

“…У наш час загальновизнано, що природні та штучні деревні насадження відіграють надважливу роль у гармонізації екологічного середовища промислових регіонів Світу та України (Banov et al, 2019;Ignatyeva, 2020). Зокрема, деревні насадження: зменшують рівні забруднення об'єктів довкілля; формують сприятливий для людини мікроклімат та створюють комфортні психологічні умови життя (Добровольський, 1979;Savosko et al, 2018;Shkvirko et al, 2019).…”

The actuality of the research is caused by the importance of understanding the laws of natural distribution of woody and shrub plant species on devastated lands of iron ore dumps of Kryviy Rih as a theoretical prerequisite for harmonizing the ecological environment of industrial regions. The aim of the research is to assess the current vital condition of woody and shrub plant species that naturally grow on devastated lands of the iron ore dump from the standpoint of the ecosystem approach. The materials of the work were the results of our own research, which were carried out according to generally accepted methods during 2020–2021 on the territory of Petrovsky waste rock dump of Kryviy Rih iron ore basin. The assessment of the current vital condition was carried out according to the method of V. A. Alekseyev. Presently, the vegetation on Petrovsky waste rock dump, which is a model for the region, is represented by natural groups, has a fragmented character and is a sparse forest. It has been established that 32 species of woody and shrub plant species (25 genera and 15 families) naturally grow within Petrovsky waste rock dump. The current vital condition of woody and shrub plant species in the dump was assessed as «weakened» (65–71 conventional points by V. A. Alekseyev’s scale). Such numerical values of the vitality of the forest stand are 21–28% lower than the control indicators (natural groupings of Gurivka forest). Our results indicate that the ecological conditions of the devastated lands of Petrovsky waste rock dump are relatively favourable for the growth and development of woody and shrub plant species. It was found that European birch (Betula pendula Roth.), ash-leaved maple (Acer negundo L.) and acacia (Robinia pseudoacacia L.) are quite adapted to the habitat conditions of the dump. The vital condition of these species was assessed as «healthy»: 90–95 conventional points by V. A. Alekseyev’s scale.
