Opis:: On the basis of the analysis of wide temporal monitoring data, a forecast of the integrated hydrochemical indicators of the waters of the Inhul river (Ukraine) was carried out. The performed analysis was also the basis for the determination of a mathematical model of natural fluctuations of the indicators studied. The determined sinusoidal dependence of the integrated water quality indicators allowed determining the average time of fluctuations concerning the processes of self-organisation of river waters. In practice, the developed mathematical models may constitute a valuable support and supplement to the existing models in the field of prediction of self-organization processes of river waters. They may also contribute to even more effective minimization of undesirable effects of anthropogenic impact on aquatic ecosystems.

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:: The dynamics of hydrochemical parameters of surface waters from the upper, middle and lower reaches of the river was analyzed. On the basis of the analysis of temporal and spatial monitoring data, a comprehensive assessment of the environmental status of the Inhulets river (Ukraine) waters by hydrochemical indicators was carried out. The study performed a comparative analysis of the river water quality assessment using different methods: an integrated assessment based on the calculation of water pollution indexes, pollution rate. A result of the evaluation of water quality in certain classes: in terms of ammonium ions and BOD5 – III quality class, the water is slightly polluted; phosphate content – V quality class, water is very low in the bottom; according to the content of suspended solids, in phosphates and BOD5 – III class of water quality, water is polluted; by a concentration of chlorides – V class of quality, degree of purity – very dirty; the value of suspended solids and chlorides – III class; in terms of the sulfate content – IV class. In general, the very excessive concentration of substances in the middle course remains stable, the environmental state is poor (quality class IV).

Opis:: The principles of sustainable development and green chemistry are priorities in the development of new technologies for the extraction of useful biologically active substances, for example, in the manufacture of medicines. The processes of extracting substances from plant raw materials have many applications. Intensification of such processes, reducing their duration, energy consumption and consumption of the extractant is urgent. The object of the reseach is the green approach to intensify the extraction processes of polysaccharide substances from plant materials. The research methodology was experimental with statistical data processing. In the field of experimental research was the process of the influence of pulsed, alternating and direct current on the intensity of aqueous extraction of polysaccharides from plant materials. The high efficiency of intensification of extraction by a pulsed electric field was studied. The process can reduce the time for obtaining water-soluble polysaccharides by 3 times in comparison with traditional pharmacopoeial convection methods and reduce energy consumption by 20 times. The significance of the pulse current parameters for effective extraction was determined: the referred pulse shape, the frequency of the pulse current for extracting the maximum amount of water-soluble polysaccharides, the pulse duration, and the optimal processing time. The green approach to the use of a moderate electric field of pulsed current to accelerate the extraction of biologically active substances is the basis of the method of intensification of other traditional mass transfer processes for the sustainable development of technology.

Opis:: It is necessary to find innovative ways to improve the environmental performance of production processes and products. The technology of extracting valuable components from raw materials of plant origin is often used in technological processes of the food, pharmaceutical, chemical and other industries. Extraction is the most energy intensive step. The factors contributing to the extraction of humic acids from plant substrates under the action of electric discharge were studied. The purpose of the work was to study the efficiency of humic acids extraction from the biosubstrate under the action of electric discharges. The physical experiment showed that the main factor influencing the intensity of extraction is the degree of grinding of the solid phase of the biosubstrate-water suspension. The efficiency of electric discharge grinding depends on the pressure amplitude at the distance of the inner radius of the chamber and the number of discharge pulses. It was established that the number of chemical reagents (alkalis), usually used in the process of extracting humic acids from peat, can be reduced many times due to the appearance of radicals and peroxide compounds in the peat-water suspension resulting from the action of an electric discharge. The prospects of the non-thermal electric discharge method of intensification of the extraction of humic acids from biosubstrates were determined.

Opis:: The influence of SAS of different chemical nature on aggregate stability and bactericidal action of nano silver colloidal solutions is investigated. Colloidal solutions of silver were obtained by restoring the argentum nitrate agent in a neutral medium. With the help of spectrophotometric method, it has been proved that such solutions are characterized by high aggregate stability compared with the use of other traditional reducing agents. Anionic SAS (sodium dodecylsulfate and sulfanol) and nonionic SAS (OS-20) increase aggregate stability of nano silver solutions, while cationogenic SAS − alcamone promotes rapid coagulation and aggregation of nano silver particles. The study of bactericidal action of the solutions to the E.coli are showed that the nano silve colloidal solution with or without presence of OS-20 and alcamone completely inhibit the growth of colonies of E.coli, that is, it’s have high bactericidal properties.

Opis:: The performed studies allowed determining the peculiarities of heavy metals accumulation in the sediments, as well as the nature of their distribution in the hydroecosystem Southern Bug (Ukraine). Geochemical anomalies are formed in the zones of influence of industrial and urban agglomerations. Technogenic pollutions of bottom sediments with heavy metals affects the qualitative state of the water environment and can cause cumulative toxicosis on the hydrobiont population in the zones of geochemical anomalies formation, namely in the area of influence of the Nova Odessa and Mykolaiv cities. The mechanism of the cumulative toxicosis emergence is accompanied by chronic effects of low concentrations on hydrobionts with an excess of permissible fluctuations on a regional background, which ultimately contributes to the development of intoxication.

Opis:: The bottom sediments of river hydroecosystems were studied for the gross content of heavy metals (K, Ti Cr, Fe, Ni, Cu, Zn, Rb, Sr and Hg). The environmental and geochemical processes of bottom-sediment formation in aqua landscapes were analyzed, allowing us to stress the need to determine the methodological basis for the correlation-regression dependence of the heavy metal accumulation processes in bottom sediments, as well as total content of organic carbon. The ranking of pairwise correlation coefficients arranged in decreasing order is: TOC:Cu (0.87) >TOC:K (0.82) >TOC: Ni (0.75) > TOC:Sr (0.73) > TOC:Fe, (0.7) >TOC:Ti (0.67) > TOC:Hg (0.63) > TOC: Cr (0.58) >TOC:Rb (0.56) > and TOC:Zn (0.51). The proposed methodological approach determines the environmental and geochemical aspects of the sedimentation processes heavy metals, while also identifying the general trends in hydroecosystems prone to the anthropogenic impact.
