Meteorological Elements

Meteorological elements affecting radioactive contamination of the environment, each indicator has a different weight in the formation of the radioactive background. The strongest influence on the spread of radioactive contamination have winds. Influenced also different rainfall and the permeability of the atmospheric layer to solar radiation reaching us. The other meteorological components have a negligible impact on the spread of radioactive rays, particles and isotopes and therefore in further research we will ignore them and will not recognize their influence on climate radioactive background. In the analysis of meteorological elements that influence the spread of radioactive particles and radioactive isotopes in Bulgaria are mainly analyzed winds and air currents that form in the airspace over Bulgaria. These are the main weather elements that most influence the climate of the radioactive background. Another element that influences is precipitation in its various manifestations - horizontal and vertical type and depending on the physical condition of the water. The other meteorological elements because of their vile influence of the radiation situation will exclude them from the factors shaping the natural indicators of the state of the atmosphere, water and pochvata.Analizat is made on the basis of detailed statistics on the direction and strength of the wind and air currents over the territory of Bulgaria in the last 30 years. In addition to daily data for the period after 2009 have used aggregated figures on the direction and strength of winds, and near the concerned areas and over throughout our country and in adjacent border areas. This data is used for a period of 20 years, which is enough to capture the trends of change of atmospheric masses and neighboring aquatic and terrestrial surfaces. I must point out that monitoring of air masses over the past 25 years gives us only the main trends and directions, but as we all know, these processes are too dynamic and not subject to cyclic steady repetition and prediction. So at the same time made extensive research and data processing should not disable the constant monitoring of our environment and its parametri.Kato main potential sources of radioactive contamination are discussed nuclear power in Europe. In analyzing the results of the forecast movements of air masses and spreading radioactive particles consequently observed that apart from the NPP "Kozloduy" and adjacent to Bulgaria Kozloduy "Black Water" at different intervals of time radioactive contamination may occur and result of an accident in other NPPs in Europe.

Visual Testing

A test method for the determination of phosphates in environmental objects has been developed, the determination of phosphate ions can be carried out in the field, the analysis of one sample is carried out for 10-15 minutes. Color characteristics can be monitored both visually and using color processing programs for smartphones such as ON Color Measure or Light Analyzer. Variants of compositions of a series of placers are proposed for visually blister colorimetric determination of phosphate ion concentrations in a blister cell (tablet for tablets) containing a mixture of reagents. The placers allow the quantitative determination of phosphates in various objects without preliminary preparation of reagent solutions. The application of reagents to the surface of silica gel makes it possible to isolate all reagents until a chemical reaction occurs. Each component in a separate placer is isolated, stable for 6 months. Test systems are recommended for semi-quantitative visual testing and for the quantitative determination of the content of phosphate ions in solutions. The composition and application conditions of crystalline substances - reagents capable of providing a sufficiently high acidity with the addition of a few drops of a solution and a reducing agent suitable under blister conditions have been optimized. Visual-colorimetric reaction is carried out under conditions when the volume of the added solution is 2-3 drops. In the environmental objects of the Belogorsky district of the Republic of Crimea, the concentrations of phosphate ions in water samples, soil of carbonate chernozem, biomass of cellulose-containing waste of lavender after extraction of lavender essential oil grown by organic farming were determined. The phosphate content was estimated by the visual blister method in the samples and standard methods, and good convergence of the analysis results was shown.

Well Waters

The work is devoted to the study of the chemical composition of well waters located on the territory of the mausoleum complex of Khoja Ahmed Yasavi. On the basis of experimental studies, the salinity of well waters increases every year. It is especially different in 2019 when, compared to the previous 10 years (2009-2018), there was a sharp increase in the total salt content by 1,5 times in the inner well and about 2,3 times in the outer well. The reason for this is the intense pollution of atmospheric air, soil, plants and other environmental objects due to an increase in the volume of construction work resulting from this waste, the number of servicing vehicles and the emergence of a number of new anthropogenic factors. The article also considers data from the Kazhydromet of the Republic of Kazakhstan that characterize changes in natural and climatic conditions, exactly, the amount of precipitation by month. Based on the calculated data, we have shown that water evaporation is 4-5 times higher than the amount of precipitation in the region. As a result of evaporation, moisture rises through the capillaries and is further saturated with salts found in building materials. Further, the formed saturated salt solution, undergoing various transformations, such as crystallization, contributes to the formation of salt deposits on the surface of the foundation materials and further walls. This negative phenomenon is one of the factors that lead to a decrease in the stability and safety of the architectural monument.

The purpose of the article is to describe monitoring studies on the radiation state of air in populated and working areas near the uranium processing enterprise in the Republic of Uzbekistan. Ac-cording to the analytical measurement, the exposure dose of gamma radiation is equivalent to the equilibrium volume activity of radon, specific activity of long-lived alpha-emitting nuclides in the zone of influence of the enterprise, the working area, premises for storing uranium materials and manufacturing dumps, tailings dams and areas of underground uranium leaching. It was shown that the measurement results do not exceed the regional background and regulatory levels of radioactive radiation by all indicators. The dependence of the volume activity of radon at production facilities on the density of the radon flux from the soil was studied. The most intensive radioactive objects – uranium dumps – were identified. It was found out that there is no excess radioactive impact of the uranium enterprise on the environmental objects.

Epidemiological Situation

The study presents a characteristic of the current epidemiological situation on leptospirosis in the Republic of Tatarstan, investigation of the circulation of leptospirosis agents among the population of small mammals, and the species composition of Leptospira that caused diseases in humans.Materials and methods. The paper contains the data on the incidence of leptospirosis among the population in the Russian Federation (RF) for the period between 2000 and 2018, in the Republic of Tatarstan – since 1998, submitted by the Rospotrebnadzor Administrations in the constituent entities of the Russian Federation, materials of the Center for Hygiene and Epidemiology in the Republic of Tatarstan and the Main Veterinary Administration of the Republic of Tatarstan.Results and discussion. We have carried out the analysis of the epidemiological situation in the Republic of Tatarstan for the period of 1998–2018, by the administrative territories of the republic. The incidence of human leptospirosis caused by various leptospira serogroups has been assessed. In total, 112 people got infected with leptospirosis during the analyzed period. Also the data of epizootiological survey of small mammals inhabiting the natural foci of leptospirosis in the republic are presented. Laboratory tests of 1565 samples from mouse-like rodents for the presence of leptospirosis pathogens have been performed. 1.9 % of the tests gave a positive result. Dominant in the Republic of Tatarstan are the serogroups of Leptospira – Leptospira grippotyphosa and L. hebdomadis. The results of laboratory studies on the carriage of leptospira among small mammals and contamination of environmental objects indicate the circulation of pathogens of leptospirosis in the population of small mammals, habitant in forest shrub, near-water and meadow field stations of the republic. The red vole prevails in this community, the average index of its dominance is 66.7 %. Epizootiological monitoring point to a latent epizootic process in the community of mouse-like rodents.

Aim. To investigate the possible relationship between content of selenium in environmental objects (soil and foods) and prevalence of tumors in the Republic of Azerbaijan. Methods. Atomic absorption spectroscopy was used for quantitative determination of selenium in soil of some economical regions of the country and in foods of every day’s local diet that are the natural nutritional sources of selenium. Serum selenium level in patients with tumors was assessed using X-ray fluorescence spectroscopy. Results. Soil and food analysis revealed low contents of selenium in them. Difference in selenium concentrations in soils from studied economic regions and in food products farmed in these regions was discovered. The serum selenium level of patients with malignancies was 37.3 μg/l (38.6 μg/l - females, 34.3 μg/l - males). There was a reverse relationship found between selenium concentrations in soils and food of the region and prevalence of tumors, as well as with serum selenium level in patients with tumors and tumor stage and malignant potential. Conclusion. The territory of Azerbaijan Republic may be considered as the region with selenium deficiency. Our research supposes that selenium deficiency can be associated with increased prevalence of malignancies in the region.
