The article describes an X-ray fluorescence method for quantitative analysis of sulfate and total sulfur in bottom sediments of watercourses and reservoirs located in the area of industrial enterprises impact. The quantitative determination of sulfur forms was carried out by analyzing the characteristic curves SKα1,2 and SKβ1,3, as well as the satellite line SKβ′ on X-ray emission spectra measured by an X-ray fluorescence spectrometer with wavelength dispersion. The study shows that these characteristic curves allow not only to determine the predominant form of sulfur, but also to separately conduct quantitative analyses of sulfates and total sulfur after fitting peaks and to separately analyze overlapping spectral lines. The results of quantitative analysis of the chemical state of sulfur by the proposed X-ray fluorescence method were compared with the results of inductively coupled plasma atomic emission spectroscopy and elemental analysis, as well as certified standard samples of soils and sediments. The results are in good agreement with each other.

Halotrichite has been identified in geothermal fields of the Kambalny-Pauzhetka-Koshelev region, the Bolshoi Semiachik complex, and the Mutnovsky volcano (Kamchatka, Russia). Halotrichite forms efflorescence on soils heated up to 70°C, around steam-gas vents and boiling springs. Tschermigite, rozenite, szomolnokite, gypsum, alunogen, barite, melanterite, hexahydrite, and minerals of the copiapite, alunite and voltaite groups were found in close association with halotrichite. The chemical composition of halotrichite samples from different geothermal fields is similar and characterized by Mg substitution in the Fe2+ position, with Fe2+:Mg ratio ranging from 90:10 to 50:50, and also by Fe3+ substitution in the Al position in some samples, with Al:Fe3+ reaching up to 85:15. Halotrichite is a typical mineral of low-temperature volcanic setting, formed as a result of alteration of parent minerals by hydrothermal fluid and represents an intermediate form of crystallization of leached elements. At the same time, the local conditions of mineral formation — such as variations in Eh, pH, surface temperature, and elemental composition — do not reflect in the chemical composition or other thin typomorphic features of halotrichite. The mechanism of halotrichite formation is probably identical in both geothermal fields and zones of oxidation of sulfide deposits.

The article presents the physical and geographical characteristics of the Synychan water intake section of the Izium water intake, which is located 8 km southeast of the city of Izium, Kharkiv region. Hydrogeological features of aquifers operated by 4 wells are considered. Geomorphological features of the studied territory are analyzed. Aspects of the geological structure of the site are also reflected. The analysis of indicators of chemical composition of underground waters of the Synychan water intake site since 2003 is presented. Among the most relevant to the task of chemical compounds, the values of nitrates, chlorides and sulfates content, as well as data on total hardness and mineralization were selected. An increase in performance is observed in all wells. The intensity of the increase is different for each production well and the corresponding chemical compound. This indicates at least the heterogeneity of influencing factors and processes occurring in the aquifers of this water intake area. Among such factors and processes, taking into account the shallow depths of wells, we can consider the technogenesis. Since Synychan water intake is used to supply a significant number of residential areas of Izyum, a detailed analysis of the dynamics of the presented data is appropriate. The study of the dynamics of the distribution of chemical indicators of groundwater composition over different periods using mathematical and graphical methods will not only allow to inductively study the dynamics in previous years, but also quantitatively predict future trends in water composition of interstratal aquifers in the region. Considering the growing and growing shortage of quality water resources in Ukraine, the analysis of data from water intake areas of Izyum can give a representative picture of the real local situation in the field of water management, hydrogeology and hydrogeochemistry of Izyum district in general and town of Izyum in particular.

The effect of quinazolines on the monoamineoxidase MAO – (EC 1,4,3,4). of rat brain tissue have been studied in vitro. Serotonin (5-OT) creatinine sulfate has been taken as substrate. Studies have shown that some quinazoline compounds as 4’ amino-5’, 8’ dimetil -1H-spiro [ciclopentan 1,2’-naftalin]-3 carbonacid in concentration of quinazolines are conditionally divided into three groups, according to the effictiency of serotonin demination (strong, moderate, weak).

Objective: To identify features of development of adaptive protective reactions when applying drinking sulfate mineral water (MW) and low-intensity electromagnetic radiation of extremely high frequency (EMR EHF) against the background of a high-calorie diet and after its elimination at an early stage of development of experimental metabolic syndrome., Material and Methods: Experiments were conducted on 40 non-linear male rats with 200-220 g. weight. The model of metabolic syndrome was reproduced for 60 days. All animals were divided into 5 groups: 2 study groups, 2 control groups and 1 intact one. Rats of the 1st study group were given sulfate MW in combination with EMR EHF against the background of a high-calorie diet, controlled by rats receiving only a high-energy diet. Rats of the 2nd study group also received sulfate MW in combination with EMR EHF but when the metabolic syndrome simulation was finished and the high-calorie diet was eliminated, control was done by rats that were given standard food after eliminating the high-energy diet. Liver, testes and blood were objects of the study. Light-optical, morphometric methods of examination and electron microscopy were used., Results and Discussion: The use of sulfate MW in combination with EMR EHF against the background of the high-calorie diet was the most cause of increased activity of the antioxidant system and the plastic processes were weaker; the activation of natural adaptive reactions was noted after the elimination of the diet that in combination with actions of MW and EMR EHF led to the further intensification of protein synthesis (RNA, DNA, total protein), intensification of cellular and intracellular regeneration processes. The identified adaptive shifts during the action of the studied factors were caused by their antioxidant, membrane stabilizing and detoxifying actions., Conclusion: The results of the study can be used to develop the problem of regulating adaptive reactions with the application of therapeutic physical factors and to create new highly effective methods of preventing and treating metabolic syndrome.

Purpose of the Study: To reveal the features of adaptive metabolic development, light-optical and ultrastructural reactions under the combined action of drinking mineral water (MW) and low-intensity electromagnetic radiation (EMR) of ultrahigh frequency (UHF) at an early stage of development of the experimental metabolic syndrome., Material and Methods: The study was performed on 28 non-linear male rats weighing 180-200 g. Animals of the experimental group on the background of a high-calorie diet received at first (from the 8th day of the experiment) a course of drinking sulfate MW (24 procedures), and after its completion - a course of low-intensity EMR UHF (12 procedures), daily, 2 minutes per lumbar region in the zone projections of the adrenal glands using the Aquaton-2 device (power flux density 1 μW/cm 2 , frequency 1000 MHz). Animals fed only a high-calorie diet served as controls; intact animals were also used. The objects of study were the liver, blood, thymus. Biochemical, histological, electron microscopic and morphometric research methods were used., Results and Discussion: The combined use of drinking MW and low-intensity UHF EMR contributed to the development of adaptive metabolic and regenerative processes: the level of glucose and high-density lipoproteins decreased in the blood, antioxidant activity clearly increased in the liver, the content of RNA, DNA and total protein increased, and the number of dystrophic and necrobiotic cells decreased. Strengthening of the processes of intracellular regeneration was manifested in an increase in the number of mitochondria, peroxisomes, as well as protein-synthesizing organelles - ribosomes and polysomes. Functional activity of the lysosomal system increased. The number of nuclei increased In thymus and specific activity of the thymocyte genome increased as well. The revealed effects were mainly due to the antioxidant, membrane stabilizing, detoxifying, and immunomodulatory effects of MW and UHF EMR., Conclusion: Based on the data obtained, it can be concluded that the combined use of drinking MW and low-intensity UHF EMR can be very promising in the light of the development of new approaches to the treatment and prevention of metabolic syndrome in the early stages of its development. To optimize the adaptive-protective and compensatory processes, more adequate modes of combined exposure to MW and UHF EMR should be used.
