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.

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.

The paper is devoted to the problems of soils contamination of some regions of the Republic ofArmenia and a city of Yerevan with heavy metals. The results of analyses of the selected soil tests for the purpose ofdefinition of their contamination degree with heavy metals are listed. The statistical data on the background concentration of heavy metals in various soil-climatic zones of the Republic of Armenia, not influenced with appreciable anthropogenous impact is also given. The comparative analysis on presence of polluting chemical elements in soil is carried out for the approved norms of maximum permissible concentration and background indicators. The authors consider possible negative influences on environment as a result of soils contamination, in particular on biological activity of soil and processes of its self-cleaning. It’s noticed that maximum permissible concentrations are mainly developed only from hygienic positions which do not consider the variety ofsoils, in particular, their properties. As an example there are described the results of soils researches of some regions of the Republic of Armenia and there is noticed that a paradoxical situation arises when background contents toxic elements in soils exceed the established values of maximum permissible concentration. In the paper there is arisen the question on necessity of working out and introducing in practice ecological monitoring of the system of tentatively permissible quantity of chemical elements in soil, taking into account background concentration of heavy metals in various soil-climatic zones. Introduction of the specified system will allow reasonably and, what very important, reliably to estimate an ecological condition of soils and to define the influence of contamination on qualitative characteristics of soil as a result of anthropogenous influence.

The intensive industrial and technological development results in an appearance of a large amount of pollutants and toxic substances in the biosphere including large quantities of heavy metals. Some heavy metals are biogenic (Cu, Zn, Se etc.) and essential for proper maintaining of the metabolism in the human body. The main dangers to the human health are associated with the exposure to toxic elements such as Pb, Cd, Hg and As. Emission of Cd in the environment has increased during the 20th century mainly due to the recycling of the products containing this element. Cadmium accumulates in the human body with a biological half-life from 10 to 30 years and could cause very serious toxic effects. Cosmetic products are potentially a source of cadmium as well as some other heavy metals mostly due to the frequent and uncontrolled usage of cosmetics of poor аnd/or suspicious quality. The goal of the study is to determine the cadmium content in various cosmetic products (lipsticks, eyeshadows and blushes) present in the markets of the Republic of Srpska. The content of Cd was determined with atomic absorption spectrophotometry (AAS) after the extraction with diluted HCl and aqua regia. The results of the research show that the cadmium concentrations in the investigated products are in accordance with the regulations of the Republic of Srpska (Regulations on safety of consumer goods; „Official Gazette RS“ – No.17/15).

Background: The paper presents the results of studies conducted on the basis of the former Smolensk branch of Pryanishnikov Institute of Agrochemistry, in the village of Olsha, Smolensk district, Smolensk region. In a long field experiment, various fertilizer systems were studied, their effect and aftereffect on the qualitative and quantitative crop yield, soil properties.Methods: A stationary field experiment was established in 1978. The aftereffect of fertilization systems on oats has been studied since 2009. The aftereffect was studied in 2015-2016 and 2017. With one dose of organic fertilizer (compost based on cattle manure - cattle), over 30 years of experience, 17.4 tons of organic matter, 435 kg of total nitrogen, 198 kg of phosphorus (P2O5), 621 kg of potassium (K2O) entered the soil. A single calculated dose of nitrogen, phosphorus and potassium corresponded to 25.5 kg of active ingredient per ha-1. Result: With prolonged use of fertilizers, the content of heavy metals in the soil did not exceed the calculated permissible concentration. However, at a fivefold norm (N150P150K150 + 15 t ha-1), the cadmium content was overestimated. An ecologically justified dose of aftereffect in the Smolensk region on sod-podzolic soil should be considered a fourfold dose of mineral components and compost (N120P120K120 + 12 t ha-1).

По инструментальным данным сетей сейсмических станций NOGSR, OBGSR, DAGSR получено следующее решение параметров землетрясения: 43,27N, 44,92E, h12 км, КР11,5. Приведены сведения по истории сейсмичности очаговой зоны исследуемого землетрясения за последние 150 лет. Очаг землетрясения приурочен к активному Сунженскому разлому. Рассмотрены форшоковая активность и немногочисленная серия афтершоков. Для землетрясения был рассчитан механизм очага по знакам первых вступлений продольных Pволн на 48 станциях, хорошо окружавших эпицентр и расположенных на расстояниях 0,3 50,5 км. Согласно полученному решению землетрясение возникло под действием преобладающих сжимающих напряжений. Тип подвижки в очаге соответствовал взбросу с правосторонним сдвигом по плоскости NP2 с юговосточным простиранием и левостороннему сдвигу с компонентами взброса по плоскости NP1 с субширотным простиранием. Для сбора макросейсмических данных сотрудниками СевероОсетинского филиала ФИЦ ЕГС РАН был осуществлен выезд в эпицентральную зону и близлежащие районы. Оценка интенсивности проводилась на основе шкалы ШСИ 17. Землетрясение с интенсивностью 5 баллов проявилось в населенных пунктах Яндаре, Троицкое, Карабулак. Колебания ощущались в Сунже, Барсуках и Плиево силой 4 балла, Назрани 34 балла. В населенных пунктах Магас, АлиЮрт, Средние Ачалуки ощутимость землетрясения составила 3 балла. В семи населенных пунктах колебания проявились интенсивностью в 2 балла. Во Владикавказе землетрясение ощущалось на верхних этажах многоэтажных зданий. Данные о проявлениях Яндарского землетрясения интересны с точки зрения анализа распределения интенсивности сотрясений, изучения сейсмичности региона в целом, а также связи с геологическим строением территории The article analyzes and presents the data on the earthquake on October 17 at 15h55m GMT, which occurred on the outskirts of the village of Yandare of the Republic of Ingushetia. Intensity of the shok equaled 5 in the epicenter. According to instrumental data of networks of seismic stations NOGSR, OBGSR, DAGSR the following solution of parameters of an earthquake is received: 43,27N, 44,92E, h12 km, KР11,5. The history of seismicity of the focal zone of the investigated earthquake for the last 150 years is studied. The earthquake is confined to the active Sunzha fault. The forshock activity and a few series of aftershocks are considered. For the earthquake, the mechanism of the focus was calculated according to the signs of the first arrivals of longitudinal Pwaves at 48 stations well surrounding the epicenter and located at distances 0,3 50,5 km. According to the received decision, the earthquake appeared under the influence of prevailing compression stresses, the type of movement the reverse fault. For collecting macroseismic data departure in an epicentralny zone and nearby areas was carried out. Evaluation of intensity was carried out on the basis of theSeismic intensity scale (SHSI17). The earthquake with an intensity of 5 points was manifested in the settlements of Yandare, Troitskoye, Karabulak. Fluctuations were felt in Sunzha, Barsuki and Plievo force 4 points, Nazran 34 points. In the settlements of Magas, AliYurt, Middle Achaluki, the sensitivity of the earthquake was 3 points. In seven settlements, the fluctuations showed an intensity of 2 points. In Vladikavkaz earthquake was felt on the upper floors of multistorey buildings. Data on the manifestations of the Yandaryearthquake are interesting from the point of view of the analysis of the distribution of the intensity of concussions, the study of the seismicity of the region as a whole, as well as the connection with the geological structure of the territory.

Dietary exposure to several heavy metals such as Cd, Cr, Pb, As represents a risk to human health through the consumption of vegetables. Due to the possible risks for the human body, contamination of soils as well as drinking and irrigation water has been the subject of many researches. In this study, the analysis of heavy metals content from soil, water and vegetable samples from households in Ilfov County it was carried out. As a result, no contamination of soil and water with heavy metals was observed. Cadmium content is above the maximum allowable limit for all analyzed vegetables, excepting cabbage and green onion. Two lettuce samples have an alarmingly high content of lead, the values being even 10 times higher than the maximum admissible limit of 0.3 mg/kg. The high values obtained for chromium content in lettuce and radish samples raise serious questions about possible contamination. Arsenic content values ranged between 0.87 and 7.69 mg/kg, which also represents high values. Based on the transfer factor (TF) calculated the strongest accumulation of the metals was in lettuce.

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.

Purpose: to determine the ecological and toxicological state of various types of chernozems in Rostov region by the content of mobile forms of heavy metals. Materials and methods. The studies were carried out on irrigated areas of Semikarakorsky, Matveevo-Kurgansky, Neklinovsky, Salsky, Veselovsky districts of Rostov region. The soils were sampled in layers of 0–20, 20–40 cm and analyzed using the method of measuring the mass fraction of mobile forms of metals by atomic absorption. Results. The content of mobile forms of the determined metals (zinc, lead, cadmium, nickel, copper) was not found to be higher than the maximum permissible concentration (MPC). The rows of the determined metals were constructed according to their share of the MPC in the 0–20 cm layer, which showed that cadmium (from 0.2 to 0.4 MPC), lead (from 0.05 to 0.12 MPC) and nickel (from 0.04 to 0.17 MPC) are closer to MPC in all chernozems of the studied regions of Rostov region. Pollutants were found in the chernozems of Salsk region in the smallest amount, except for copper (0.09 MPC). The content of copper in soils 0.04–0.35 mg/kg indicates its low and stable distribution in the studied soils, except for Veselovsky district, where the analysis showed values below the detection limit, which may indicate a lack of copper as a trace element. According to the soil grouping for ecological and toxicological assessment by the content of mobile forms of heavy metals, they belong to the 1st group, i.e. the soils contain pollutants below the MPC and are suitable for the cultivation of all agricultural crops. Conclusions. The ecological and toxicological state of soils of the surveyed areas by the content of mobile forms of zinc, lead, nickel, cadmium and copper is assessed as satisfactory.

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.
