The article presents the results of studying the composition of road dust in Tyumen, a large city in Western Siberia. On roads with different traffic intensities, 50 dust samples were taken, in which the particle size distribution, pH, and organic carbon content were determined. The content of 62 major and trace elements was studied using atomic emission spectrometry (AES-MS) и inductively coupled plasma spectrometry (ICP-MS). It was revealed that the dust has an alkaline reaction pH = 7.4 - 10.2, low organic carbon content (0.07 - 2.9%). The particle size distribution is dominated by particles PM = 100-250. The content of small particles (PM Sb (1.5) > Cr (1.3) > Zn (0.4) > Co (0.4) > Cu (0.2). The contamination evaluation through enrichment factor (EF) calculation showed that road dust is highly enriched in Ni and significantly in Cr and Sb. More than 80% of Zn, Co, Cu and more than 90% of Ni, Sb, Cr come from anthropogenic sources. By the content of Ni and Cr, Tyumen surpasses all cities of the Earth where similar studies were carried out. The high Ni content is associated with the composition of local soils and roadways, increased content in vehicle exhaust gases, and abrasion of metal parts. Calculations of the total pollution indices (IPI and Zc) showed that the level of road dust pollution in most of Tyumen's territory is average, moderately hazardous.

A study on the composition of snow allowed for a quantitative determination of pollutants deposited from the atmosphere. Concentrations of dissolved ( 100 were emitted from anthropogenic sources. According to the potential ecological risk index (RI), the worst ecological conditions were identified in Tyumen’s historical center, industrial zone and along roads with the heaviest traffic. The data obtained in the present study allowed us to identify the most polluted parts of the city, which are located in the center and along the roads with the most intensive traffic. This research could offer a reference for the atmospheric pollution prevention and control in Tyumen.

According to the World Health Organization, more than 80% of urban residents are at risk due to unsatisfactory air quality and air pollution, which causes approximately 4.2 million deaths per year. The purpose of the work is to give an overview of scientific articles related to the dustiness of the city’s natural environments. The articles of foreign and Russian researchers were analyzed - the definition of urban road dust was given; the primary technogenic and natural sources of dust particle generation in the city, thephysical and chemical properties of road dust, their dependence on climate, the type of roads and city architecture, the effect of photolysis on physicalchemical characteristics of dust particles are reviewed as well. Particular attention is paid to the negative impact of dust particles PM2.5 and PM10 on human health and the environment. The question of the absence in Russian scientific practice an officially recognized methodology for the settled dust sampling with updating the regulatory documentation on the methodology for the sampling of fine particles suspended in the air is considered. Recommendations are given on the creation of the regulatory framework governing the sampling and analysis of road dust, which is confirmed by the numerous conclusions of both foreign and some domestic researchers as an environmental geo-indicator.

In order to evaluate the chemical composition of natural background environments of Pur-Taz interfluve (Western Siberia), the mineral components of soils, peats, lichens, and sphagnum mosses have been analyzed. The samples were tested using X-ray fluorescence technology. The average contents of hazardous metals in the soils of the Pur-Taz interfluve are either lower (for Cu, Pb, Zn, Ni, Sr) or equal to (for Hg, Co) the average values of these elements in the Earth's crust. This finding corresponds to the commonly held view that the contents of elements in the soils located in the north of Western Siberia are lower than the world averages. Additionally, in our samples low concentrations of copper and zinc have been observed. Since these microelements are important for soil physiology, this finding indicates unfavorable biochemical conditions in the research area. On the other hand, high concentrations are observed for inactive elements such as Mo, Sn and Zr. The significant differences have been identified in the composition of mineral and organic soil horizons. For instance, the average concentrations of P, Zn and S in organic horizons are 7.1, 8.1 and 18 times greater than in the illuvial mineral horizons, respectively. The intense accumulation of Zn, Cu, Cd, Hg has been recorded, all of them are chalcophiles in the ombrotrophic peat. This means that the chemical composition of soil is largely determined by biological accumulation of chalcophile elements. The content of lithophilic Al, Si, Ti and Zr, coming with dust precipitation from the atmosphere increases in the peat of dwarf shrub-moss-lichen tundras and larch woodlands. The revealed values of the elemental composition of soils can be recommended as background in the course of the environmental monitoring.

Water quality in the Agan River catchment (West Siberia, Russia) was assessed based on data obtained between 1993 and 2017 at 25 monitoring stations. The purpose of the research was to assess the impact of oil field development on the quality of surface waters. Monitoring stations were located in the oil fields characterized by various levels of impact, from “moderate” (number of wells < 0.5 per 1 km2) to “extreme” (number of wells > 1 per 1 km2). Comparisons with the thresholds indicated that metal (Ni, Hg Pb, Zn, Cu, Mn and Fe) concentrations exceeded the standard limits for fisheries in 10.8%, 14.5%, 22.3%, 24.7%, 54.7%, 88.6% and 99.2% of samples, respectively. The high contents of Mn, Fe and Cu can be generally regarded as the natural results of intensive leaching of elements from acid soils. The total petroleum hydrocarbons (TPH) value exceeds the threshold in 34.6% of samples. The water quality was estimated using the Canadian Council of Ministers of the Environment Water Quality Index (CCME WQI). The water quality of the Agan River catchment was classified as “poor” and “marginal”. The TPH values displayed a significant positive correlation with the density of wells and with the percentage of oil-contaminated lands. Positive correlations were found between Cl− and the density of wells, the frequency of accidents and the area of contaminated lands. Trends of pollution are sensitive to changes of accident rate. The decrease in accident rate for the last decade resulted in declines in TPH and Cl concentrations.

The total concentrations of metals (Fe, Mn, Cu, Ni, Cr, Sr) and their mobile forms extracted by an ammonium acetate buffer (pH = 4,8) were studied in soils samples collected from Nadym-Pur interfluve (West Siberia), near the northern limit of the taiga zone. The heavy metal content was determined in 55 background soil samples and in 25 pyrogenic ones. Gross content was determined on a spectrometer "SPECTROSCAN MAX-GV" using X-ray fluorescence analysis. Mobile forms of metals were determined on a ContrAA 700 atomic absorption spectrometer by flame and electrothermal methods. The statistics are calculated using the Excel software package. The study confirmed the weak accumulation of metals in the soils of the northern regions of Western Siberia. The total content below the soil world average for Fe is 5 times, Mn – 3 times, Sr – 2 times, Cr – 1,4 times. The content of mobile forms varies widely depending on the amount of organic matter. The percentage of mobile forms of metals from the total content was: Cr – 0.84%, Fe – 1,2%, Sr – 3,8%, Mn – 8,7%, Ni – 15%. In the profile of podzols, the distribution of mobile forms of metals has an eluvial-illuvial character. Mn and Sr accumulate intensively in the surface organogenic horizons, and the Fe content increases in the BF horizon. Minimum values are marked in horizon E. In pyrogenic soils, there is an increase in the content of mobile forms of metals due to the intake of ash. Metal content usually not exceeded the maximal permissible concentrations for soils.

The Numto Natural Park, Khanty-Mansi Autonomous Okrug – Yugra, Russia, has recently attracted the attention of environmental organizations due to oil extraction operations in its territory. This paper presents the study of the vegetation cover dynamics and the assessment of natural and anthropogenic disturbances of Numto’s ecosystems. Due to the development of oil deposits, more than 60 adventitious plant species arrived to the park, and the synanthropization index reached 26.4%. Tree rings showed the predominant influence of the climatic and pyrogenic components on the growth of trees. The technogenic impact that had occurred in the 1990s gave a spasmodic increase in cedar growth in the disturbed areas in the form of abnormal hard streaks. Later on, the impact of technogenic factors on the wood growth waned. Satellite imagery helped to determine changes in the vegetation cover. From 2011 to 2018, the area of disturbed sites doubled while the length of infield roads and pipelines increased by 5.7 times. The area of burnt fire sites increased manifold; how-ever, fires occurred at a considerable distance from the oil extraction sites and were of natural origin. Currently, the disturbed ecosystems, including burnt fire sites and fire-damaged ecosystems, occupy 2.1% of the oil deposits area, and the area of pyrogenic disturbances is larger than the area of technogenic ones. Compared to the oil and gas fields in the adjacent areas, the level of disturbance in the Numto Natural Park can be considered low. Since deer pastures were not disturbed by the oil extraction opera-tions, the traditional nature management remains possible. Further oil field development requires ongoing monitoring of the ecosystem condition.

В условиях промышленного освоения и эксплуатации объектов нефтегазового комплекса ранее нетронутые ландшафты Крайнего Севера подвергаются значительному негативному воздействию. В связи с этим необходимо проводить экологический мониторинг различных природных сред, данные которого, позволяют изучить масштабы антропогенного влияния и оценить экологическую обстановку полярных регионов. Цель работы заключается в определении интенсивности атмосферных выпадений микроэлементов и оценке экологической ситуации в Пур-Тазовском междуречье, на участках с различной техногенной нагрузкой (фоновая территория, пос. Тазовский, Заполярное газовое месторождение). Для экологической оценки атмосферных выпадений выполнен отбор проб торфяных отложений верхового типа. В пробах методом атомно-абсорбционной спектрофотометрии (ААС) определено содержание микроэлементов (Cd, Cu, Pb, Zn, Ni, Cr, Mn) и железа. Выявлены высокие значения показателя зольности, что свидетельствует о значительной пылевой нагрузке для обследуемой местности. В районе пос. Тазовский в отдельных пробах отмечено превышение содержания элементов-загрязнителей над фоновым уровнем в 2–5 раз, в районе Заполярного месторождения – в 3–7 раз. Средние значения коэффициента концентрации Кс < 1,5 для всех элементов, кроме Cd, в связи, с чем он считается приоритетным загрязнителем. По результатам подсчета суммарного показателя загрязнения Zc на Заполярном месторождении отмечен один участок с умеренно опасным уровнем загрязнения, которое в целом в районе исследований носит умеренный характер.

The concentrations of several trace elements and iron were determined in 26 soil samples from Belyi Island in the Kara Sea (West Siberian sector of Russian Arctic). The major types of soils predominating in the soil cover were sampled. The concentrations of trace elements (mg kg−1) varied within the following ranges: 119–561 for Mn, 9.5–126 for Zn, 0.082–2.5 for Cd, <0.5–19.2 for Cu, <0.5–132 for Pb, 0.011–0.081 for Hg, <0.5–10.3 for Co, and 7.6–108 for Cr; the concentration of Fe varied from 3943 to 37,899 mg kg−1. The impact of particular soil properties (pH, carbon and nitrogen contents, particle-size distribution) on metal concentrations was analyzed by the methods of correlation, cluster, and factor analyses. The correlation analysis showed that metal concentrations are negatively correlated with the sand content and positively correlated with the contents of silt and clay fractions. The cluster analysis allowed separation of the soils into three clusters. Cluster I included the soils with the high organic matter content formed under conditions of poor drainage; cluster II, the low-humus sandy soils of the divides and slopes; and cluster III, saline soils of coastal marshes. It was concluded that the geomorphic position largely controls the soil properties. The obtained data were compared with data on metal concentrations in other regions of the Russian Arctic. In general, the concentrations of trace elements in the studied soils were within the ranges typical of the background Arctic territories. However, some soils of Belyi Island contained elevated concentrations of Pb and Cd.

В статье проведена оценка экологического состояния водно-болотных угодий международного значения «Верхнее Двуобье». Расположенное на р. Обь ниже впадения в нее Иртыша, «Верхнее Двуобье» является одним из крупнейших водно-болотных угодий России. Угрозу для его экосистем несут расположенные в пойме объекты нефтедобычи. Проведен анализ химического состава двух водных объектов — главного русла р. Обь и прот. Ендырская за период 2003-2016 гг. Обработка результатов мониторинга показала, что воды пресные, маломинерализованые, имеют нейтральную или слабощелочную реакцию. Содержание аммонийного азота повышено во все гидрологические сезоны. Воды содержат большое количество железа и марганца, превышающее рыбохозяйственные нормативы, что типично для таежной зоны Западной Сибири. В особенности велико содержание марганца, которое в 3-10 раз выше среднерегиональных значений. Содержание свинца, хрома, фенолов низкое, более чем в 50% проб ниже предела обнаружения. Воды прот. Ендырская, по сравнению с главным руслом Оби, отличаются более высоким содержанием практически всех компонентов. Проведена оценка интенсивности техногенного воздействия в разные периоды освоения нефтяных месторождений. Максимальный уровень нефтяного загрязнения поверхностных вод и донных отложений наблюдался в 2007-2008 гг. В 2007 г. превышение предельно-допустимых концентраций было выявлено в 75% проб из главного русла Оби и в 61% из прот. Ендырская. В 2008 г. превышение ПДК было отмечено в 25% проб главного русла Оби и 44% — прот. Ендырская. Максимальный уровень загрязнения совпал с наибольшим объемом буровых работ и наивысшей аварийностью на объектах нефтедобычи. В последующие годы случаи загрязнения были единичны, эколого-геохимическое состояние водных объектов стабилизировалось.
