Assessment of the Influence of Aluminum, Iron, and Manganese Forms on the Phytocenoses of Post-Mining Lands in the Lengerskoye Brown Coal Mine Akmaral Issayeva, Waldemar Spychalski, Elźbieta Wilk-Woźniak, Dariusz Kayzer, Radosław Pankiewicz, Wojciech Antkowiak, Bogusława Łeska, Akmaral Alikhan, Assel Tleukeyeva, Zbigniew Rozwadowski Sustainability Switzerland, 2025 Post-mining land in areas where mineral extraction has occurred may constitute a significant portion of the land used for various purposes. Such land serves as soil-forming parent material for developing anthropogenic soils, which sometimes exhibit unfavorable physicochemical properties. The toxicity of the waste generated during lignite mining is due to a number of factors, whose determination permits the identification of its origin for the subsequent design of technologies for the waste reclamation. The purpose of the study, in consistence with sustainable development, is to identify the causes of the toxicity of brown coal waste from the Lengerskoye deposit, in southern Kazakhstan. These studies have provided the results essential for planning remedial actions necessary to improve the well-being of the local population, in accordance with the principles of sustainable development. The studies were performed using single extraction; forms of Al, Fe, and Mn; soil texture; elemental analysis; phytocoenosis analysis; and diffractometric, IR spectroscopic, SEM, route reconnaissance, and comparative statistical methods. A decrease in the biodiversity of plant species was noted, with a gradual increase with distance from the waste storage sites. The most resistant plant species in the vicinity of the waste dump were Cynodon dactylon (L.) Pers and Alhagi pseudalhagi (M. Bieb.) Desv. ex B. Keller & Shap., while Dodartia orientalis (L.) was the only plant species found at the edge of the waste dump. The high toxicity of lignite waste is determined by such factors as low pH values, about 3.0; high content of active forms of aluminum, iron, and manganese (344.0, 0.90, and 20 mg/kg); high electrical conductivity—2835 µS/cm; waste composition poor in nutrients; and climate aridity. It has been observed that a content of exchangeable aluminum above 100 mg/kg resulted in an almost complete lack of vegetation.
Study of the Possibility of Biorecultivation of Soils Contaminated with Brown Coal Waste Akmaral Issayeva, Akmaral Alikhan, Kulaisha Tlegenova, Gulzhaina Alpamyssova, Yerzhan Issayev, Assel Tleukeyeva Journal of Ecological Engineering, 2024 Environmental pollution by industrial waste, including brown coal mining, is one of the environmental problems of many countries. To improve the ecological situation in the region, it is necessary to recultivate soils contaminated with brown coal waste. The goal of the study was to study the possibility of biorecultivation of soils polluted with brown coal waste from the Lenger deposit located in the south of Kazakhstan. It was found that the inorganic part of the brown coal waste is represented by minerals: Quartz SiO2, Gypsum CaSO4×2H2O, Kaolinite Al2Si2O5(OH)4, Cronstedtite- Fe3((Si0.74 Fe0.26)2O5)(OH)4, Margarite- CaAl2(Si2Al2)O10(OH)2, Muscovite H2KAl3(SiO4)3, Calcite CaCO3, Laumontite CaAl2Si4O12(H2O)2, Lead Aluminium Sulfate Hydroxide Pb0.5Al3(SO4)2(OH)6, with quartz content in samples in the range of 61.5 - 92.9%. The organic part of the waste is 90.0% made up of humic acids and fulvic acids. It has been established that heterotrophic, cellulolytic microflora and micromycetes are represented by the genera Rhodococcus, Bacillus, Pseudomonas, Penicillium; Trichoderma, Dietzia, promising for biorecultivation purposes. The phytocenosis of coal waste dumps is composed of toxicotolerant ruderal plant species of the local flora: Centaurea scabiosa L., Centaurea iberica Trev., Cichorium intybus Linn., Cousinia cyrdariensis Kult., Achilleamille folium L., Thlaspiar vense L., Arctiumto mentosum Mill., Onopórduma cánthium L., Agropyron cristatum L., Phlum pratense L., Erytrigia repens L., Nevski / Agropyron repens L.,Cynodon dactylon L., Capparis spinosa L., Polygonum aviculare L., Dodartia orientalis L., Althaea officinales L., Alhagipseud alhagi (Bieb.)Desv., Peganum harmala L. For biorecultivation of soils contaminated with brown coal waste, an algorithm of work has been developed, including the use of soil blocks with integrated seeds of toxicotolerant plants inoculated with microorganisms.
Selection of the composition of the fertilizer and optimal factors for the cultivation of green microalgae on phosphorus—Containing waste in the south of Kazakhstan Issayeva Akmaral, Alpamyssova Gulzhaina, Tleukeyeva Assel, Ospanova Zhanna, Akhmet Ainagul, Tleukeyev Zhanbolat Journal of Infrastructure Policy and Development, 2024 Modern agricultural production technologies based on the widespread use of pesticides and mineral fertilizers have largely solved the problem of providing the population with food, and at the same time have generated multiple ecological, medical and environmental problems, problems of environmentally friendly and biologically valuable food products, land rehabilitation, restoration of their fertility, etc. Therefore, the emergence of new classes of pesticides with different mechanisms of action, high selectivity and low toxicity for warm-blooded animals is very modern. Currently, the development and application of new plant protection products that are not toxic to humans and animals is of global importance. Priority is given to research aimed at creating plant protection products based on microorganisms and their metabolites, as well as the search for plant substances with potential pesticide activity. In this regard, the question arose of finding new safe fertilizers that can also be economically profitable for production on an industrial scale. One of the current trends in this industry is the use of green microalgae. In this regard, the purpose of our research is the possibility of cultivating green microalgae on phosphorus production waste. During the work, traditional and modern research methods in biology were used. As a result of the work, several problems can be solved, such as the disposal of industrial waste and the production of safe biological fertilizer.
Study of the Properties of New Strains of Green Microalgae Cultivated on Residual Phosphorus-Containing Waters Assel Tleukeyeva, Akmaral Issayeva, Talgat Ibragimov, Yerzhan Issayev, Gulzhaina Alpamysova, Kulaisha Tlegenova, Radosław Pankiewicz Polish Journal of Environmental Studies, 2024 Rational use of natural resources implies waste-free production without a negative impact on the environment. Biotechnological methods are often the most effective in solving the problems of waste disposal due to the fact that they are based on natural mechanisms of self-healing in disturbed ecosystems. The aim of the study was to isolate and study the properties of new strains of green microalgae cultivated on residual phosphorus-containing waters, which are promising for the production of biofertilizer. Based on the study of algaeflora from natural reservoirs and wastewater in the south of Kazakhstan, strains of green microalgae <i>Chlorella vulgaris</i> ASLI-1, <i>Chlorella vulgaris</i> ASLI-2, and <i>Oocystis borgei</i> AТР were isolated, capable of consuming phosphate phosphorus and ammonium nitrogen from residual waters in places of storage of solid phosphorus-containing waste.
Microorganisms of solid waste as an opportunity for waste disposal and increasing environmental sustainability in the south of Kazakhstan Ainagul Akhmet, Saulet Karimova, Alisa Zhumadullayeva, Saltanat Ashirbayeva, Kulaisha Tlegenova, Akmaral Alikhan, Akmaral Issayeva, Assel Tleukeyeva, Bakhytzhan Kedelbayev Journal of Infrastructure Policy and Development, 2024 The study is devoted to the problem of processing the organic waste that is generated as a result of paper, textiles and other industries production as well as food waste. The growth of economic activity in Kazakhstan has resulted in a significant challenge with regard to industrial waste management. The accumulation of waste on the territory of the country has reached 31.72 billion tonnes, comprising approximately 2.5 billion tonnes of hazardous waste, 50 million tonnes of phosphorus-containing waste, over 2.5 million tonnes of lead-zinc waste and more than 120 million tonnes of solid domestic waste. The study object was the Shymkent-Kokys polygons. According to the research carried out, it was determined that the titer of microorganisms of the studied groups is 1–10 CFU/g in the soils selected around the garbage in the area of the Shymkent landfill. The titer of microorganisms in the soil horizons was high at a depth of 20–30 cm and the titer were 109 cells/mL. The structure of the soil microbiome obtained around the Shymkent Waste Landfill consists of actinomycetes, micromycetes, heterotrophic bacteria, nitrifying, nitrogen-fixing bacteria, enterobacteria, as well as algae and protozoa. It was found that strains KPA1, KPA2 Pseudomonas sp. strains KPA3, KPA4, KPA5 Bacillus sp. isolated from the soils of the Shymkent-Kokys landfill are able to recycle domestic waste with a high content of cellulose and organic substances up to 95%–97%. The findings can be used to develop more effective organic cellulosic waste management strategies and improve the environmental sustainability of various industries.
Soil Pollution with Heavy Metals in the Turkestan Region Yerbol Salim, Aizhan Yerimbetova, Togzhan Baiduisenova, Aigul Uspabayeva, Roza Abildayeva, Aigerim Balgabekova, Saltanat Ashirbayeva, Assel Tleukeyeva Journal of Ecological Engineering, 2023 Toxic pollutants of industrial origin can be dangerous for professionals who come into contact with them at work, and also for the people who live near the sources of environmental hazards. There is a known relationship between the soil pollution with heavy metals and the morbidity of the population. This paper reports a study of the soil pollution with ions of heavy metals in the Turkestan region, Kazakhstan. The study found technogenic geochemical anomalies of various size, intensity and origin in the soils of the Turkestan region. The distribution of lead, copper, barium, zinc, molybdenum, phosphorus and arsenic was mapped based on the ecological and geochemical survey of the upper soil layer. The most polluted city is Kentau, where concentrations of Pb, Mo, Cu, Zn, As, Cd, Mn, Cr, Ni in the soil exceed the allowable level. The cause of pollution is erosion that occurs in the areas of technogenic waste storage. In some communities, the concentration of only one metal exceeded its MAC or the Clarke number, for example, only scandium exceeded its Clarke number by 1.1 in Lenger and only exceeded its Clarke number by 2.75 in Sholakkorgan.
Possibilities of Using Medicinal Plant Extracts and Salt-Containing Raw Materials from the Aral Region for Cosmetic Purposes Izabela Nowak, Akmaral Issayeva, Marta Dąbrowska, Agata Wawrzyńczak, Henryk Jeleń, Bogusława Łęska, Azhar Abubakirova, Assel Tleukeyeva Molecules, 2022 The aim of this work was to study the possibility of using medicinal plants in combination with salt-containing raw materials from the Aral Sea region for cosmetic purposes. The chemical and mineralogical compositions of salts occurring in this region were studied for pharmacological and cosmetic purposes. The salt-containing raw materials were studied by X-ray diffraction (XRD), thermogravimetric analysis (TGA) and scanning electron microscopy (SEM). The microflora of saline-containing raw materials and flora of the Zhaksy-Klych lake were studied. Fifty-six plant species were identified, of which 25% belong to the Asteraceae family, 32% were Poaceae, 22% were Amaranthaceae, and 21% were Tamaricaceae. Using the solid-phase microextraction (SPME) method and comprehensive two-dimensional gas chromatography–mass spectrometry, the composition of volatile compounds in such plant species as Artemisia alba L., Achilleamillifolium L., Eleagus commutate Bernh. Ex Rydb., Psoraleadrupacea Bunge, Artemisia cipa O. Vegd., Thymus vulgaris L., Morus alba L., Salvia pratensis L., Glycyrhizaglabra L., Tanacetum vulgare L., Polygonumaviculare L., Alhagipseudoalhagi Gagnebin and Peganumharmala L., chosen on the basis of their herbal components for future cosmetic products, was determined. In total, 187 different volatile compounds were found in the endemic plant species Glycyrrhizaglabra L., of which the following were dominant: 1,7-octadiene-3-, 2,6-dimethyl- with a peak area of 4.71%; caryophyllenes; bicyclo[7.2.0]4,11,11-trimethyl-8-methylene-, [1R-(1R*,4E,9S*)]—3.70%; bicyclo[2.2.1] heptane-2-1,7,7-trimethyl-,(1S)—3.46%; cyclohexanone, 5-methyl-2-(1-methylethyledene)-; 2-isopropyledene-5—2.97%; menthol; cyclohexanol, 5-methyl-2-(1-methylethyl)-; p-menthane-3-ol; menthol alcohol; and 2-isopropyl-5—2.08%. The remaining compounds were detected in amounts of less than 2.0%. Tests of seven cosmetic compositions developed on the basis of plant extracts and salt-containing raw materials revealed that three samples had a moisturizing effect. Launching the production of cosmetic products in the Aral region will not only reduce social tensions but also significantly improve the environmental situation in the region.
The Use of Phosphorus-Containing Waste and Algae to Produce Biofertilizer for Tomatoes Assel Tleukeyeva, Nuradin Alibayev, Akmaral Issayeva, Lyazzat Mambetova, Aygul Sattarova, Yerzhan Issayev Journal of Ecological Engineering, 2022 The current state of phosphorus-containing waste and the methods of its disposal remain relevant. The storage of phosphorus-containing waste sludge is carried out in sludge collectors, which occupy large areas. With the disposal of slags and sludge, as well as the elimination of sludge collectors, the harmful effect of waste on the soil will cease, and the possibility of using these areas for economic land use will appear. Many studies show the movement of phosphorus in soil and water, thus proving the difficulty of disposing of this waste. Of course, phosphorus slags and sludge are used in small quantities in the production of building materials, but this does not solve all the problems. In the south of Kazakhstan, there are warehouses for the waste from the production of phosphorus-containing fertilizers, which also require disposal. One of the ways of modern utilization of these wastes is their use in fertilizers for agriculture. However, since the phosphorus-containing waste has a high content of phosphorus, compared to nitrogen and potassium, this ratio can be changed with the addition of chlorella biomass. The purpose of the conducted study was to investigate the possibility of using a complex of phosphorus waste and algae, that is, the cultivation of chlorella at various concentrations of phosphorus-containing waste for further use of the suspension in watering the test plant. In the form of a test plant, tomato seeds were chosen, the cultivation of which in agriculture is economically profitable. When cultivated in closed ground, tomatoes lose their taste, which can be restored with the use of organic fertilizers. This article shows the results of the influence of various concentrations of phosphorus waste and green microalgae on the growth and development of Solanum lycopersicum.
Reaction of Aquatic Plants of Small Rivers of the Turkestan Region of Kazakhstan to Heavy Metal Ions Akmaral Issayeva, Zhanar Myrzabayeva, K. Kidirbayeva, Talgat Ibragimov, G. Baitasheva, Assel Tleukeyeva Journal of Ecological Engineering, 2022 Heavy metals are some of the environmental pollutants that have a serious impact on the environment. The analysis of hydromacrophytes growing in small rivers of the south of Kazakhstan with different contents of heavy metal salts revealed that the morphometric indicators of the same plant species differ significantly, depending on the level of total mineralization of the aquatic environment in different rivers of the Turkestan region. It has been established that two plant species can be used to bioindicate the content of lead ions in the aquatic environment: Azolla caroliniana Willd. and Veronica beccabunga L., which must be introduced into the tested aqueous solutions in the amount of 1.0 kg/m 3 and 1.5-2.0 kg/m 3 , respectively, to fully cover the water column at different depths. The first morphological changes in plants, in the form of destruction of the structure of chloroplasts along the edges of unfolded leaves in A. caroliniana Willd. and slight withering of the lower underwater leaves in V. beccabunga L., occur already at a 1.5 mg/l Pb 2+ content in water, and a further increase in the content of lead ions in water to 600.0-800.0 mg/l leads to the death of plants.
Green Algae as a Way to Utilize Phosphorus Waste Assel Tleukeyeva, Radoslaw Pankiewicz, Akmaral Issayeva, Nuradin Alibayev, Zhanbolat Tleukeyev Journal of Ecological Engineering, 2021 The possibility of using phosphorus-containing wastewater as a raw material for the cultivation of the green algae strain Chlorella vulgaris ASLI-1 can represent an effective processing of phosphorus-containing by-products. A laboratory experiment was made to study the effect of the concentration of phosphorus-containing wastewater on the biomass density of the green alga strain Chlorella vulgaris ASLI-1. Three weeks after sowing, we measured the biomass density of algae in various components of the phosphorus-containing wastewater. Compared to the control (distilled water), the addition of phosphorus-containing wastes did not adversely affect the culture of green algae, with the exception of a 20% medium where algal cells were discolored and had a low biomass density, 104 CFU. However, more research is needed to better study the response of green algae to phosphorus-containing waste, to determine the amount of phosphorus in cells and solution. In addition, evaluate the agronomic efficiency of the Chlorella vulgaris ASLI-1 strain, cultivated on phosphorus-containing waste, when applying fertilizers for growing vegetables.
