The drainage basin is spatially and functionally clearly defined and relevant hydrologic, geomorphologic and ecologic landscape totality. Therefore, it mostly represents basic geo-spatial unit of generation, monitoring, and studying numerous physical-geographical and geo-ecologic occurrences and processes. One of the most important components of geo-space, on the level of basin, is manifested through the state and quality of surface waters. So, the acceptance of systematic approach in studying mineralization of the surface waters would contribute to the deeper understanding of the process in complex systematic surroundings which drainage basin represents. The Visocica Drainage Basin was chosen as proving ground of this kind of the research approach for several reasons. The highest specific runoff on the territory of Eastern Serbia, heterogeneous geologic structure of terrain, almost complete absence of the influence of the anthropogenic factor on the state of the environment, as well as the existence of water accumulation enabled perception of the values of dissolved mineral substances of surface waters as landscape-ecologic component of geo-space.

The work examines modern methodological approaches to assessing the quality of life using environmental indicators. Analysis of the existing methods in Ukraine for determining the environmental component when measuring the quality of life showed the need to develop a new method for a comprehensive assessment of the state of the environment. This is due to the fact that the existing methodology for assessing the quality of life does not take into account the ecological component as a separate block of indicators, and also contains some inaccuracies in the formulas for calculating the final indicator. In this regard, a new method is proposed for determining the ecological component in the general system for assessing the quality of life of the population, which is the scientific novelty of the work. Based on the analysis of monitoring data on the quality of air, surface waters and soils of Ukraine, statistical reporting on environmental indicators of the development of regions of Ukraine, intermediate indicator indicators are calculated, and then the final complex indicator of the state of the environment is determined. Calculation formulas and assessment scales in points of the state of environmental components are proposed. The proposed method is based on the processing of data from official state statistics and environmental monitoring, which determines the reliability of the initial data. The proposed technique can easily be used as an algorithm for computerized calculations of the indicator of a comprehensive assessment of the state of the environment. The calculation of the indicator of the ecological state was made on the basis of current statistical data, which showed the need for immediate environmental protection measures in the industrially developed regions of Ukraine: Donetsk, Zaporozhye, Dnepropetrovsk and Lugansk regions.

The article analyzes the flaws of the classical measures of economic growth. It is based on the assumption that, while not questioning the quality of the GDP indicator as a tool for measuring economic activity, it points out that the way this indicator is constructed influences the actions of governments, citizens and other actors, affecting also non-productive areas. What we measure affects what we do - if production is measured, then the criterion determining the success of the state and society will be the growth of production, and not the level of education, health or state of the environment. Gross domestic product in many cases includes production that, from the point of view of the community, indicates unfavorable processes. These are the so-called anti-goods, i.e., phenomena that increase GDP, although they worsen well-being and are socially undesirable).

In the urban environment, the main sources of pollutants entering the atmosphere are industrial enterprises and vehicles, which leads to a significant change in the composition of the air. Various monitoring methods are used to analyze the state of the atmospheric air. On their basis, methods have been developed to monitor the state of the natural environment of the technosphere. Most often, gas analyzers and various chemical methods for determining aerosol pollution are used. The creation of a methodology that makes it possible to quickly and efficiently assess the state of the environment is urgent. The described method of rapid assessment of the state of atmospheric air by bioindication and biotesting of dendroforms makes it possible not only to quickly and qualitatively assess the quality of atmospheric air, but also to take appropriate environmental measures in a timely manner. The developed rapid assessment includes several stages of the assessment of the objects under study, carried out depending on the goals of the study. To test the methodology, the objects of the study were the most anthropogenically loaded public green spaces (PGS) - public gardens of Sevastopol, located in different administrative districts of the city. The obtained results showed the possibility of using the developed methodology both in stages and in a complex manner.

The aim of this article is to present the results of multidimensional comparative analysis methods used to assess the state of the environment in Dolnośląskie voivodship in the cross-section of powiats. The research was conducted on the basis of data from the CSO of Poland for 2015 concerning the state and environmental protection in 30 powiats of Dolnośląskie voivodship. The method of linear ordering of objects based on a pattern object (or an anti- -pattern object) was used in the research. Many of them described in the subject literature usually lead to differing results (rankings of objects are not the same). It results from i.a. the adopted methods of normalization and weighing of variables and aggregations (creation of synthetic variables). The article is an attempt to compare the results of linear ordering of powiats due the environmental state with the use of method based on a pattern object (or an anti-pattern object). In the rankings correctness analysis, quality indicators were used to evaluate the quality of linear ordering methods.


Purpose. To assess the level of pollution of the atmospheric air and the surface waters of the Zaporozhye region, as well as assessing the technogenic loading on the natural environment of the region. Methods. Statistical. Results. The obtained results indicate that the highest values of the atmospheric pollution index are defined in such substances as formaldehyde, phenol, nitrogen dioxide and nitrogen oxide. The surface waters quality of the Zaporozhye region was characterized as "poorly polluted", class I – "polluted", class II. The assessment of the loading on the air basin showed a gradual decrease in the level of loading. The contribution of mobile sources is about 50 % of the total emissions. For the surface water, there is also a significant decrease in a loading module index. With the amount of accumulated waste, a loading level increases. For a generated waste amount, a maximum amount is solid household waste. The overall assessment of a technogenic loading on the region shows that in 2010 – 2012, the maximum values of a man-caused load module were characterized. A slight decrease in an anthropogenic pressure level is noted. This is due to the reduction of pollutants emissions into the atmosphere and the generation of waste in 2013 – 2015. Conclusion. Zaporozhye region belongs to the technogenically stressed regions. Priorities for improving the state of the environment are activities related to reducing the amount of pollutant emissions into the atmosphere and the generation of waste.

Introduction .With a significant number of water bodies in Ukraine (only 2,000 small rivers), the descriptive characteristics of the ecological situation occupy a significant amount, which requires unification and encryption. Dr.Ph. Klymenko M.O, Dr. Ph. Gryb J.V. made the unification of research materials by blocks: type of basin-morphometric of the catchment surface, floodplains and riverbeds - quality of the aquatic environment - production characteristics - socio-demographic - block of economic analysis of profitability in river basins and cluster costs analysis of the state of the components of the ecosystem and assessment of the basin as a whole. The study of individual elements of the water basin (composition and quality of the aquatic environment, the state of the catchment surface, ichthyofauna, forage base of aboriginal ichthyofauna, the impact of economic activity) provides some information. There is a significant array of surface water monitoring data (hydrochemistry, ecology, hydrobiology, ichthyology, etc.), attributed to the middle and end of the twentieth century. Here it should be noted the works of Kononenko G.D., Gryb J.V., Alekseevsky V.E, Baranovsky V.A, Klymenko M.O, Tsvetova O.V, Sondaka V.V, Chernyavskaya A. P., Zhukinsky V.N and others. They established the regional features of the chemical regime of surface waters, developed a methodology for assessing the quality of surface waters and the state of transformation of the catchment surface, the peculiarities of the formation of crisis situations. Dr.Ph. Gryb J.V. researches of a chemical mode of surface waters on phases of a hydrological mode for the period from 1970 to 2000 are carried out. Kononenko G.D. conducted mapping of the territory of Ukraine by the main ions of the mineral composition of water. The State Institute of Eastern and Northern Europe (Germany) together with the Institute of Geography of the National Academy of Sciences of Ukraine on the basis of applied research of Ukrainian scientists: Rudenko L.G., Chernyavska A.P., Gryb J.V. with the participation of scientists G. Friedline, G.A. Vernichenko, T.P .Balashova, I.P. Semenova conducted a study of the state of rivers in Ukraine and drew up a map of water quality and suitability for use (1995). A map of soils of Ukraine, stock-forming and underlying rocks was also issued. Purpose . Among the important scientific results of the study is the need for unification and unification of river basins. Methodology According to the EU framework directive, the river basin and its elements are accepted as a unit of spatial research of water bodies: channel, floodplain, accessory network (number of intermediate ecotones). These include the following elements of the basin: first-order currents, second-order tributaries, floodplain. Old villages, floodplain lakes, swamps, meadows, springs, as well as subsystems of the catchment area: forest, water mirror, plowed and barren lands, urban areas and infrastructure. Assessment of the condition is carried out on three levels: good, satisfactory, bad. Collectively, the water basin is accepted as a biome that shapes the quality of surface waters, their productivity, diversity of flora and fauna. The hydrographic network itself forms the landscape and connects its elements through hydro-ecological corridors - river systems. The following mathematical dependences are used in the creation of the bio-skeleton framework of the water basin, with the increase of the values of the characteristics the value of the golden root r1 is 1.68 with the decrease of r2 - 0.68. In the pentosystem series of characteristics (classes) the numbers of phyto-swings for biological processes 1,2,3,5,8,13,21,34,55 are used. Results. An example of encryption of field research materials of the Lviv River (a tributary of the first order of the Pryt River) is presented in formula (1) АП; R1; Z3; Z42; E1; L; Ie; b5 5; R3; Ke5; St 3,0. (1) Plain part of Ukraine, Western Polissya region, Dnieper river basin, main canal, regulated, one intermediate Eco tone (channel reservoir), water is weakly mineralized, channel is straight , water quality class one, fish productivity is weak, the state of the basin is over drying, stability is low (low water, segmentation of the channel by locks, protective sand from unaligned slopes of the shore). Similarly, other blocks can be coded. In the perspective owe will obtain the results of the correlation with the conclusions of other scientists, in particular Klymenko M.O., Gryba J.V. and others. Thanks to encrypting the data by blocks of pool structure, we can unify the methods of research, facilitating the work of researchers and students. Conclusions 1. The economic and ecological framework of the water basin is one of the leading blocks for assessing the ecological situation. And the main indicator is the ecological and economic potential of the territory and the cost of the basin. 2. To assess the transformation of the state of the basin, reference values of the state of the enterprise are needed. 3. In assessing the situation, the final block is the economy and demographic situation - the cost of living and its duration.

The use of robots to perform tasks traditionally assigned to people leads to an improvement in the quality of their implementation, a reduction in the costs and risks associated with them. A typical example of this is the task of monitoring and examining hard-to-reach areas. The introduction of robots to solve such problems could bring a significant economic and social effect, allowing the automation of a number of complex, time-consuming and potentially dangerous tasks, such as the compilation and updating of maps and three-dimensional models of emergency sites, the collection of data on the state of the environment in areas, exposed to biological or radiation contamination, continuous monitoring of the state of the environment and sampling of air and soil. The paper considers one of the possible designs of such robots: a wheeled jumping robot, which consists of an acceleration module for jumping(used to for overcome obstacles), and a wheel platform, which allows the robot to use wheeled locomotion when moving over the surfaces with small irregularities. The advantages of such a combined system include higher maneuverability and higher speeds of movement, as well as a wider functionality in terms of the range of terrains suitable for movement. For this robot, a design scheme has been developed and two critical positions of the device are identified, which allows to formulate conditions that impose limitations on the geometric parameters of the body, the acceleration module and the wheels, and their mutual arrangement, in order to ensure operation of the robot in two modes: wheeled and jumping. The results of modeling are presented in the form of permissible ranges for the length and height of the body, as well as the maximum length of the acceleration module from the radius of the wheels and the location of their installation point, taking into account the capability of the acceleration module to do a complete rotation within the robot’s frame .

The main sources of chemical pollution of surface water bodies of Ukraine are shown and it is noted that the ecosystem of the environment and water resources, being under constant man-caused load, tend to steadily deteriorate the ecological condition. Methods for assessing the quality of surface waters using the maximum allowable concentrations of harmful substances in water and a comprehensive assessment of the ecological status of surface water by integrated hydrochemical parameters are described. International approaches to the assessment of the state of surface water bodies are considered. It is noted that the most complete information on the state of the aquatic ecosystem can be obtained using a set of physicochemical and biological parameters. There are shortcomings in the monitoring of organic micro-pollutants in surface waters. The analysis of the international experience of determination of water quality and parameters of toxicological action of organic micro-pollutants with application of chemo-informative methods for modeling of an ecological condition of water systems is carried out.
