Abstract:
AbstractIncreasing interest in nanomaterials can be explained by their broad involvement in many fields of industry and medicine. It is known that carbon black and crysotile asbestos behave like nanosized objects. They are wide spread in environment and have close contact with living organisms. The aim of our study was to define the effects of carbon black and crysotile asbestos on structures of the developing organism.We used chicken embryos as a model for our study. Total amount of 77 eggs was divided in three groups: one control and two experimental with introduced carbon black and asbestos respectively. Researched materials were injected in the yolk on the third day of incubation and tissues for study were taken during early, middle and late stages of incubation. Histological and electron microscopy methods were used.Carbon black and asbestos introduction caused underdevelopment of embryos and vessels depletion in blood islands of the yolk sac. Asbestos slowed down angiogenesis. Soot particles caused integrity violation of vessels and led to extravasation. The manifestations of soot influence were damages to blood circulatory system and structural disorders on cellular level. Introduction of chrysotile asbestos mostly resulted in compensatoryadaptive reactions like increasing in hematopoiesis and transcytosis in endotheliocytes.

Abstract:
On the example of the Irkutsk oblast, the problem of air pollution with technogenic and natural fires is considered. The factual basis of the study was the statistics of the consequences of fires in residential, public, industrial and other objects of the technosphere and natural fires, also combustion of forest combustible materials in the residential, landscape-recreational, forest-park, suburban zones of cities and settlements for 2011-2016. On the basis of existing approaches, qualitative and quantitative indicators of burned materials are determined as a result of technogenic and natural fires, ignition, and specific indicators of toxicant emissions in the combustion of various types of materials, which allowed to comprehensively determine the gross emissions of pollutants in the Irkutsk oblast. It is established that as a result of technogenic and natural fires, ignitions, the annual gross emissions of pollutants averaged about 18.2% of the mass of stationary sources of pollution in the oblast.

Abstract:
Technogenesis is a process of environmental transformation under the influence of various types of technical human activity. Technogenesis - this transformation of the earth's crust occurs during the extraction and processing of mineral resources, engineering and geological activities. One of the technogenically transformed areas is the Pavlodar region of Kazakhstan. This scientific article presents the main sources of technogenic impact in the Pavlodar region. The research gives a description of the two main technogenic systems. There have been determined the main chemical contaminants of the components of the natural environment. The authors have calculated using modern methods of GIS technologies, the area of sludge collectors. The article describes a promising method for solving such non-trivial problems as identifying the spatial distribution of ecological risk zones, or the spatial display of the concentration distribution of pollutants. The article gives a description of the main industrial facilities of the Pavlodar region, the number of emissions, and also characterizes the climatic factors of the study area.

Abstract:
Plants of modern urban ecosystem suffer from negative effects of a series of technogenic pollution which leads to changes in their morphological and physiological state. The reason for this is the penetration of phytotoxicants into plant organs, primarily, into leaves, thus distorting the structural components of cells and their functioning. In various species the degree of this reaction is manifested differently, so this fact must be taken into consideration when creating environmentally effective plantations. For this purpose the integrated study of the impact of pollutants on the morpho-physiological state of deciduous trees was conducted. Some morphological, physiological and biochemical indicators of leaves of Tilia cordata Mill., Populus tremula L., Salix fragilis L., Salix alba L. from different urban areas, characterized by different levels of technogenic pollution, were also studied. It was found out that the increase of technogenic load led to the decrease in the size of leaves, the increase of their necrotization and the total ash content of the tissues of these organs as well as the reduction of the photosynthetic pigments concentration with increase of relative portion of carotenoids which is the most significantly revealed in the leaves of the lime-tree, brittle willow and, to a lesser extent, in the white willow. At the same time the increased relative portion of carotenoids in the photosynthetic organs in case of strong pollution by pollutants indicates an increase of the protective role of the yellow pigment. Besides, the increased ratio of chlorophyll a/b characteristic for the resistant plant species was established in the leaves of these trees, which is a sign of a higher potential photochemical activity of leaves and the rate of photosynthesis. All the studied morpho-physiological indicators characterize a greater resistance to pollutants of Tilia cordata, Salix fragilis, Salix alba, which can be recommended for the reconstruction of the sanitary and protective plantations of Arzamas. The studied tree species have a great capacity of gettering harmful technogenic substances with a further effective ability to accumulate them in the tissues of the leaves.

Abstract:
Results of the study about pollutants content in soils of urbanized landscapes are presented. Patterns of their migration and accumulation in main soil types of Brovary are grounded. Correlation relationships between the individual components of ecologicalgeochemical system of urbanized territory were analyzed. Dependences of landscape resistance to technogenic pollution on the level of conservation of natural geochemical parameters of soils, degree of their anthropogenic transformation and level of heavy metals were determined. According to geochemical criteria technogenic associations of heavy metalsin soils are determined, which are represented by the following elements: Cu>Pb>Zn>Co>Cr>V>Mo>Mn>Ni. Level of gross content of chemical elements compounds in soils of different zones of the city is heterogeneous. City zones with the highest polyelement contamination of soil have been identified. Maximum technogenic load is recorded in urban areas of transport infrastructure zone and zone of production and communal-warehouse facilities. Ecological and geochemical assessment on the total index of pollution by using methods of Y.E. Saeta, is shown. Value of this topsoil parameter in Brovary (0-10 cm) ranges from 30 to 106, the average is 65, which corresponds to hazardous level of soil pollution. According to the total indicator of technogenic pollution, Brovary belongs to cities with high pollution level. Soils in all parts of the city, except for residential areas, are classified as hazardous. Studied soils of the city are characterized by plumbum geochemical specialization. High levels of zinc, manganese, cobalt and chromium were also found (the maximal permissible concentrations in soil exceeds by 1.7-4.7 times). Especial attention is paid to the patterns, mechanisms of pollutants influence on the complex of soil properties and processes that determine the ecological condition of soils and their resistance to anthropogenic flows. Soil contamination by pollutants leads to changes in their physical and chemical properties (cation exchange capacity pH, organic matter content) which causes a low buffering capacity of soil cover of the city.

Abstract:
Results from laboratory experiments are presented on extraction of zinc available in waste from lead-zinc metallurgy, mixed with lead-zinc flotation tailings and some waste rock, by leaching it under atmospheric conditions with sulfuric acid (H2SO4) solutions (5 and 10 wt. %) and 30 % hydrogen peroxide in the temperature range of 25 - 80 °C, at leaching time 30 - 120 min. Material leaching with 10 % H2SO4 solution at 70 °C for one hour brings into pregnant leach solution (PLS) around 80 % of zinc available. Imposing an electrochemical impact during the leaching process increases the quantity of leached zinc by around 5 %. Direct electrowinning from the PLS obtains zinc metal of grade 75-76 %. The suggested treatment removes metals-pollutants from accumulated mixed technogenic waste therefore rendering it more environmentally friendly. Experiments showed that old mixed waste from mining, mineral processing and metallurgy activities merits further studies as secondary source of metals.

Abstract:
Consumption and pollution of natural resources must be constantly compensated by their conservation, saving and restoration to create a balance in the ecosystem between man and nature. To solve this problem any construction process must be accompanied by geoecoprotective measures. The authors of the article suggest to use silica sol in the soils stabilization and reinforcement technology. Silica sol is a pure mineral product that has binding properties and neutralizing properties against some pollutants. This makes it suitable for soils reinforcement and also soils neutralization from pollutants such as heavy metals ions. The stabilization technology using technogenic soils and silica sol will conserve natural resources, improves the soil strength properties and neutralize them from pollutants.

Abstract:
Radionuclide contamination poses serious hazards for terrestrial ecosystems. Beyond the readily apparent damage to the biota at high doses, low doses of ionizing radiation produce stochastic effects: mutation, carcinogenesis, and genomic instability. The proposed chapter is a review of the biological and ecological effects of radionuclides. The authors discuss, beyond the Chernobyl accident, other contamination events. The review includes the biological and ecological effects of the three principal technogenic contaminants in terrestrial ecosystems: Cs-137, Sr-90, and I-131. Ecological risks to terrestrial small mammals are assessed in detail. In addition, the chapter provides some of the lesser-known methods of remediation and detoxification, including the use of modified natural zeolites as environmental remedies and bio-sorbents. Presented herein is little-known information on environmental protection against radioactive contamination.

Abstract:
Несмотря на значительное количество публикаций по оценке состояния загрязнения водных объектов тяжелыми металлами, направление требует дальнейших исследований. В основу концептуальной модели положено предположение о том, что чаша водохранилищ речного бассейна, наряду с морем или озером, является конечной дреной материала, поступающего со склона и потенциальной ловушкой для тяжелых металлов - длительное время находящихся вблизи мест осадконакопления. Такие участки являются зонами распространения загрязнителей и создают негативное воздействие, как для водной фауны, так и в рекреационных зонах. В основу мониторинга загрязнения объектов исследования положено ранжирование исследуемых объектов от общего к частному: наиболее крупные участки - первой категории представляют территорию, ограниченную водоразделами по берегам реки и дамбами водохранилища - по течению. Обосновано выделение каждого из четырех таксонов районирования территории для мониторинга. Предложены временные принципы режимных наблюдений для каждого из выбранных природно-техногенных таксонов районирования. Приводятся элементы концепции системы поддержки принятия решений (СППР) и необходимые требования для создания соответствующей информационно-аналитической веб-системы. Данная система основывается на современных цифровых технологиях и включает следующие компоненты: реляционная база данных, подсистема авторизации пользователей, веб-приложение с поисковым механизмом, облачное хранилище данных, а также подсистема резервного копирования базы данных, мониторинговых данных и служебных файлов.Despite a significant number of publications on the assessment of water pollution by heavy metals, the direction requires further research. The conceptual model is based on the assumption that the reservoir basin of the river basin is the final drain of material coming from the slope and a potential trap for heavy metals that are located near sedimentation sites for a long time. These areas are areas where pollutants are distributed and have a negative impact on both aquatic life and recreational areas. The monitoring of pollution of research objects is based on the ranking of the studied objects from General to particular: the largest sections of the first category represent the territory limited by watersheds along the river banks and dams of the reservoir-downstream. The allocation of each of the four zoning taxa for monitoring is justified. Temporary principles of regime observations for each of the selected natural and technogenic zoning taxa are proposed. The elements of the decision support system (DSS) concept and the necessary requirements for creating an appropriate information and analytical Web system are presented. This system is based on modern digital technologies and includes the following components: a relational database, a user authorization subsystem, a Web application with a search engine, a cloud data storage, and a database backup subsystem, a monitoring data and service files.

Abstract:
Bottom sediments formed in the water bodies under the technogenic impact are important environmental factors affecting water quality and hydrobiota. Usually they consist of natural and technogenic material and differ from natural formations by their morphology, chemical and lithological composition, physicochemical and biochemical properties. In the present paper we use the term “sediment layer of anthropogenic impact” to define the sediment layer containing technogenic material and/or chemical pollutants. The determination of its location in the sediment cores, its thickness and accumulation chronology is an important scientific problem. In the paper the results of layer by layer study of Cs-137, Am-241, Pb-210 specific activities as well as concentrations of petroleum components, lead and mercury in 48 sediment cores of the Sea of Azov and the Don River are examined. The sediment core layers are dated by radiological methods. In all the sediment cores the peak of Cs-137 specific activity related to the Chernobyl accident was detected. In the Sea of Azov, this peak is located in the upper sediment layer up to 10 cm thick, however, in the delta and in the near-delta part of the Don River, where the sedimentation rates are more important, it is found at 20 to 40 cm depth. Also in certain sediment cores the second peak of Cs-137 related to the global nuclear fallout of the 1960s was found. The most of petroleum components, lead and mercury quantities are concentrated in the upper sediment layer formed in the last 50 to 70 years, i.e. in the period of the most important anthropogenic pressure. So, this complex approach based on the data on the vertical distribution of technogenic radionuclides and common pollutants in the sediment cores made it possible to identify and delineate the sediment layer of high anthropogenic impact as well as to assess the duration of this impact.

Abstract:
The growth of production zones in the city of Aksai in the West Kazakhstan region leads to contamination of the soil cover, which, in turn, causes a chain reaction of pollution. Due to soil contamination, soil moisture and the underground surface are polluted. As a result, the processes in the soil change, the vital activity of plants, animals and microorganisms are disrupted. The article presents data on the study of changes in soil cover under the influence of human activity. The results of the conducted studies on the determination of the humus content and pH level, the content of heavy metals in technogenically disturbed soils in the adjacent territory of the natural gas processing enterprise are presented. The obtained data on the gross content and mobile forms of heavy metals indicates that the maximum permissible concentration level for these pollutants is not exceeded.

Abstract:
The territories of industrial cities are objects of active human influence on various natural processes. One of the most acute problems of the present time is the contamination of soils with heavy metals (HM). The main carrier phase of TM in urban soils is technogenic magnetic particles. A common group of particles of technogenic origin are magnetic spherules. The origin of magnetic spherules is associated with the work of industrial enterprises of metallurgical profile, thermal power plants and motor transport. The study of the morphology and composition of the magnetic phase of the soil allows us to identify the sources of pollution. According to the results of magnetic susceptibility, the content of heavy metals and magnetic particles in soils, the level of contamination and their ability to resist it are evaluated. Forest soils are the most sensitive to pollution. Therefore, the study of the composition and properties of magnetic spherules as potential environmental pollutants in Perm is relevant. The composition and properties of magnetic spherules of forest soils in Perm remain poorly understood.

Abstract:
Gelendzhik is the resort town, there aren't a lot of industrial enterprises here. The main pollutant is transport. The work purpose is the assessment of a condition of the artificial landings of a pine located along the Federal highway "Don" and landings, which is nearly the sea coast. Researches were conducted to a standard technique of the General vital state (A. S. Bogolyubov). The assessment of a condition of pines was carried out during 6 years: from 2010 to 2015. For carrying out research we used 6 experimental grounds on the Markotkhsky spine and 2 control grounds within the town. We investigated 24 trees on each platform, middle age of the trees were 30 - 40 years. Results. 1. The condition of trees in the pine forests located in immediate proximity with the Federal highway "Don" (No. 1, 2, 3) is unsatisfactory. As even weak influences of the majority of atmospheric gaseous pollutants (sulphurous gas, nitrogen oxides, etc.) give effect of a necrosis and hloroz of pine needles, the condition of pines is connected with technogenic pollution. So near the Federal highway "Don" the air environment is strongly polluted by exhaust gases. Information of 2012 confirm that negative influence of the route on Markotkh's vegetation decreases at reduction of load of the route. 2. On the sites located above on a slope (No. 4,5,6) thanks to remoteness and the wind mode intensity of influence of pollutants is lower and a condition of pines the quite satisfactory. 3. Trees on the sites located near the sea (No. 7,8) are in a good shape. Small deterioration of a state is noted in very droughty years. Conclusion. Results of six years' research show that the condition of the plantings which are in close proximity with the road worsens. It is explained by increase in intensity of the movement on the road, especially during a resort season. Gelendzhik is the city with a good ecological shape, but the damage to environment is already caused. If not to take measures, we can lose a unique part of the nature in the future, recreate it will be impossible. Measures of reduction of negative impact of exhaust gases were offered. Results of researches are transferred to ecological department of the City administration of Gelendzhik.
