Introduction. The population using waste man-made water reservoirs for recreation and providing household needs can be a potential health risk. Such pollutants as heavy metals do not undergo decomposition processes. They accumulate in the biotic and abiotic components of the reservoir. Subsequently, hazardous toxicants can enter the human body through food chains. An ecological and hygienic assessment of the state of the waste reverse reservoir of the Semyonov gold recovery plant has been carried out. Material and methods. The object of the study is located in the Zauralye of the Republic of Bashkortostan at the geographical coordinates 52° 30’20″ N, 58° 19′48″ E. The content of heavy metals (Zn, Cu, Pb, and Cd) in water, bottom sediments and biomass of aquatic macrophyte (Potamogeton perfoliatus L.) was studied. In the bottom sediments, mobile forms of metals have been detected. They are extracted by an acetate-ammonium buffer with pH = 4.8 Results. It has been revealed that in water the concentration of heavy metals is higher than the maximum permissible concentrations for fishery reservoirs: 19-27 times for copper, 10-24 times for zinc, 2.7-5.8 times for lead, 1-1.4 times for cadmium. Exceeding the standards for water bodies for drinking, domestic and cultural water use is recorded for cadmium (6 times) and lead (2.5 times). In bottom sediments, the zinc content of mobile forms is 372.00 ± 28.51 mg/kg, copper - 144.37 ± 4.08 mg/kg, lead - 14.09 ± 1.48 mg/kg, cadmium - 0.036 ± 0.002 mg/kg. The total index (ZC), reflecting the additive excess of the background, is 1686, which corresponds to an extremely high level of man-made pollution of bottom sediments. The concentrations of heavy metals in the aboveground and underground organs of Potamogeton perfoliatus L. are much higher than the background levels. Conclusion. The waste reverse reservoir of the Semenov gold extraction factory is potentially dangerous to the local population health when it is used for breeding poultry, watering cattle, and fishing. The activities aimed at improving the environmental and hygiene situation in the territory of the locality are imperative.

The features of the accumulation of heavy metals in medicinal plant raw materials Tanacetum vulgare L. in the conditions of the Trans-Urals region of the Republic of Bashkortostan are discussed. The variation-statistical indices of the content of heavy metals in soils and in plants are calculated. Soils and plants have high coefficients of heavy metals variation, with the exception of manganese in the soil, which is characterized by moderate variability. An increased level of heavy metals mobile forms, such as Cu, Zn, Mn, Fe, Pb, Cd, has been detected in all soil samples. All selected samples had an elevated level of mobile forms. According to the degree of contamination, the studied soils were classified as permissible. In tansy plants, the concentration of trace elements-biophiles exceeded the norm in Fe 1.7–6.24, in Cd 1.3–1.7 times, and the concentrations of Cu, Zn, Mn, Pb in the aboveground and underground parts of the species remained within the normal range. It is revealed that the root system of Tanacetum vulgare L. contains higher values of the studied elements than the aerial parts. According to the intensity of absorption, the elements are arranged in the following sequence: Zn → Cd → Cu → Fe → Mn → Pb. According to the coefficient of biological accumulation in tansy, ordinary zinc and iron belong to the elements of weak accumulation, copper, manganese, lead, cadmium –to the elements of weak capture.

Introduction. The article presents the results of the study of the quality of soil cover in the cities located in the mountainous areas of the Trans-Urals in the Republic of Bashkortostan. The object of the study was the soil of lands for various purposes in cities of Uchaly, Sibay, and Baymak. In the study of soils of industrial zones, there were taken samples adjacent to the dumps and tailing dumps of mining production at a distance of up to 500 m. In the recreational zone there were included the territories of parks, in the residential zone - all micro-districts where the population of the city resides. There were investigated territories of collective gardens located near sources of pollution. Material and methods. The gross content of heavy metals and their mobile forms extracted from the soil of ammonium acetate buffer at pH 4.8 were determined by atomic absorption. Generally accepted ecological values of maximum permissible concentrations (MPC) and regional geochemical background (RGF) were used to estimate the degree of soil pollution. To assess the degree of soil pollution, the total ZC index was calculated using the formula proposed by Yu. E. Saet. Results. As a result of the study, in all studied samples of the soil excess of MPC on gross forms on the content of Cu, Zn, in some cases, Mn, Cd, Co was revealed. Calculations of the General norm of Zc showed urban soil lands of all types of purpose by gross content to belong to the category of permissible pollution. The level of soil contamination with heavy metals in all the studied cities is higher in soils for industrial purposes. Increased level of mobile forms of Cu, Zn, Mn, Cd was revealed in all studied soil samples. The soils of the residential zone of Baymak according to the content of mobile forms belong to the moderately dangerous category of pollution, the rest of the studied soils had an acceptable category of pollution. In the cities of Sibay and Uchaly, the territories adjacent to the quarry dumps belong to a particularly dangerous category of pollution. Conclusion. The level of soil contamination with heavy metals in urban areas of the Mountainous region of the Republic of Bashkortostan is determined by the type of destination of urban land. The most polluted are the soils of industrial zones located in close proximity to mining enterprises. The ecological danger of pollution is that in this zone there is a part of residential neighborhoods with knots, as well as garden cooperatives, where potatoes, vegetables and fruit and berry crops are grown.

In the Republic of Bashkortostan, in the greenhouse of the year-round operation of the experimental farm of the state-run vocational training school "Ufa forestry-technical school" (Limonary in Ufa city), tropical and subtropical fruit crops have been cultivated for many years. The farm constantly monitors the agrochemical, physico-chemical, biochemical indicators of soil grounds. The agrochemical characteristics of soils during the cultivation of exotic fruit crops have been studied. For fertilizing all cultivated plants of the farm, organic and mineral macro- and micronutrient fertilizers are regularly added at regular intervals. When using fertilizers, the need for nutrient elements of crops is taken into account for successful growth and fruiting by periods of growth and agrochemical data. The study presents a comparative characteristic of soil grounds for 2016 and 2018, which shows: humus content, mobile forms of P2O5 and K2O, mineral forms of nitrogen, pH (salt). The results of agrochemical surveys allow you to adjust the dose of fertilizers for the cultivation of major crops, planting material and for the formation of the crop.

The One

This paper highlights the link between education status and cultural capital, on the one hand, and migration likelihood, on the other hand. The conclusions are based on two surveys of respondents living the Republic of Bashkortostan. The desire to continue one’s education and the dissatisfaction with one’s current education level are among the key factors that drive the local population to change their permanent place of residence. Cultural capital, in turn, is viewed through the prism of skills and knowledge, everyday leisure practices, and values. For instance, the greater a group’s computer and Internet literacy, the higher the share of people who are ready to permanently move to a different place. Those locals who express their readiness to migrate are generally younger; they tend to spend their free time online, acquire self-taught skills, pursue creative hobbies and sports etc. They value life-long learning, independence, initiative, and a desire for change, and plan their future a long way in advance. By contrast, respondents who do not plan to migrate tend to prefer traditional pastimes and practices: gardening, watching television, reading newspapers, going to church or mosque, performing home repairs etc.

The paper deals with the problem of ecotoxicants content: arsenic, mercury, lead, cadmium in the soils of Achkhoy-Martan District settlements of the Chechen Republic and their impact on human health. The presence of heavy metals in soils and plant samples of the studied area can be explained by the geological structure of the territory of the Republic, which is located on the rocks of the Jurassic and Paleogene periods. Studies have shown excessive concentrations of lead in some samples of soil settlements of the Achkhoi-Martan District: Samashki is 43,1 mg/kg and Janda - 42,1 mg/kg vs 30 mg/kg by the MPC. There is an excess of the maximum permissible concentration of cadmium in the village Zakan-Yurt - 1,93 mg/kg against 1,0 mg/kg MPC. As for mobile forms arsenic, mercury and cadmium are found in the greatest quantities. The arsenic content exceeds the permissible values by 2,03-3,36 times, the cadmium content exceeds the MPC by almost 2 times - 1,93 mg/kg against 1 mg/kg. According to the results of the studies, the relationship between the transformation of mobile forms of heavy metals from soil to plants is monitored. A direct correlation between cancer and the concentration of heavy metals in the soils of the study areas was revealed.

This paper studies the content of heavy metals (Cu, Zn, Pb, Cd - metals-toxicants and Fe) in the surface natural waters of small rivers on the western slope of the Irendik ridge in the Baimak District of the Republic of Bashkortostan. The western slope of the Irendik ridge from Lake Talkas to Lake Grafskoe is characterized by the absence of significant anthropogenic sources of environmental pollution in contrast to the eastern slope of the Irendik ridge at the same latitude. The studied rivers are located on this section of the western slope and are left tributaries of the upper reaches of the Tanalyk River. It is these small rivers that determine the chemical composition of the water in the upper section of the Tanalyk River. The content of heavy metals in the waters was determined by atomic absorption spectrometry. For the environmental assessment of waters, the multiplicity of exceeding the maximum permissible concentrations of heavy metals for fisheries reservoirs was used. The studies have shown that in the waters of small rivers on the western slope of the Irendik ridge there is an increased content of a number of heavy metals, namely copper, iron, zinc, lead and cadmium. Increased concentrations of heavy metals in the waters of the studied rivers are caused by geochemical factors.
