Item Сontents "Environmental problems" Volume 1, number 1(Publishing House of Lviv Polytechnic National University, 2016)Item Pollution of soil environment with mineral fertilizers and ways of their migration deep into the soil(Publishing House of Lviv Polytechnic National University, 2016) Gumnytskiy, Jaroslav; Lyuta, OksanaOne of the major problems of pollution of soil environment, namely by components of mineral fertilizers due to their massive and continuous use in agriculture was analysed in the article. Possible ways of penetration of not absorbed mineral fertilizers deep into the soil as the main reason for getting fertilizers in the lower layers of the soil environment were investigated. A comparison of the impact of soil and climatic conditions on the rate of penetration of fertilizers deep into the soil was done.Item Adaptation of IUCN Сlassification schemes for environmental safety passports of species(Publishing House of Lviv Polytechnic National University, 2016) Kryvomaz, TetianaThis study aimed to improve the ways of risk assessment for environmental safety. The implementation of “Environmental safety passports of species” is of practical importance for effective risk assessment of individual species impact to the environment, humans and other living organisms. The classification schemes of International Union for Conservation of Nature for evaluating habitats, threats & stresses, use and trade, livelihoods of species were analyzed and adapted to the requirements of environmental safety. Some sections such as general information about species, their distribution, ecological classification, metabolism features, risks evaluation and beneficial use were itemized to be included into the structure of ESPS.Item Influence of Dobrotvir thermal power plant on environmental specifications(Publishing House of Lviv Polytechnic National University, 2016) Pohrebennyk, VolodymyrThe influence of the emissions of Dobrotvir TPP on the state of environmental pollution was evaluated: the state of air and soils and the state of waste management. The necessity to perform combined researches and ecological measures to reduce the negative impact of waste dumps on the environment was justified. It was established that the state of soils of ash and slag dumps was in crisis, the content of total forms of heavy metals in the soil is 2–10 times higher than TLV or a background concentration, large excesses of heavy metals of the I class of danger, namely Copper, Zinc and Lead were detected.Item Tritium and its place in the overall radiation Ukraine technogenesis(Publishing House of Lviv Polytechnic National University, 2016) Kotovenko, Olena; Miroshnychenko, Olena; Marchenko, IrynaThe problem of migration accumulation of tritium, as one of the radionuclides with low radiation doses, is of great value for Ukraine in our time. The current state analysis of the tritium migration accumulation in the components of eco – and biosystems taking into account its biological effect on living organisms is the aim of the study. The paper presents a general model of ecological system state changes under the influence of tritium migration flows.Item Mutation of the Drosophila melanogaster L. under the influence of the electromagnetic radiation(Publishing House of Lviv Polytechnic National University, 2016) Nykyforov, Volodymyr; Sakun, OksanaBrief results of the previous studies of the effect of electromagnetic radiation on the fruit flies are quoted. The influence of electromagnetic radiation of industrial frequency on the living organisms has been investigated. Correlative dependence between phenotype Drosophila melanogaster L., duration and intensity of harmful factors has been established. Phenotypic manifestations have been fixed and Drosophila melanogaster L. mutation under the constant influence of the magnetic field induction from 2,25 to 20 μТ in three generations of test objects have been characterized. The dependence of the increased frequency of mutations occurrence and the increase of their diversity caused by the increase of magnetic field induction has been revealed.Item Reduction of the environmental threat from uncontrolled development of cyanobacteria in the waters of the Dnieper reservoirs(Publishing House of Lviv Polytechnic National University, 2016) Malovanyy, Myroslav; Nykyforov, Volodymyr; Kharlamova, Olena; Synelnikov, Alexander; Dereyko, KhrystynaWe have analyzed the ecological hazard that has emerged as a result of the construction of hydropower plants on the Dnieper, which became the cause of uncontrolled development of cyanobacteria. The environmental risks that are caused by the uncontrolled development of cyanobacteria and their biodegradability were studied. The efficiency of application of the known methods of suppression of mass development of the blue-green algae was analyzed. The amount of biogas that can be synthesized from cyanobacteria biomass of Kremenchug reservoir was estimated. The strategy of avoiding the ecological disaster from the uncontrolled development of cyanobacteria and its negative impact on the environment was suggested.Item Development of mathematic model of gas-turbine unit combustion chamber functioning(Publishing House of Lviv Polytechnic National University, 2014) Mandryk, Oleh; Mykhailiuk, YuliyaThe article presents the basic issues of ecological safety improvement of present-day steady-state gas turbine units. A mathematic model of diagnostics of combustion chamber considering the basic parameters of gas-turbine unit (GTU) operation under different technological modes was developed. These modes include the intake air temperature of the axial-flow compressor, the intake temperature of the actuating medium of the directing set of the high pressure turbine as well as the temperature of the environment.Item Methodological principles of electromagnetic screens application for public protection from electromagnetic fields and radiation(Publishing House of Lviv Polytechnic National University, 2016) Glyva, Valentyn; Panova, Olena; Voloshkina, OlenaThe growing levels of electromagnetic fields require the improvement of protective shielding methods. Frequency and amplitude parameters of fields have been analyzed according to national and international standards of electromagnetic safety and guidelines on shielding application have been given. The methodological principles of choosing and applying electromagnetic screens depending on radiation parameters and the required protection efficiency have been developed.Item Ecological safety of visual environment and videoecological perception (VEP) of Vinnitsia(Publishing House of Lviv Polytechnic National University, 2016) Bondarchuk, Olga; Petruk, VasylThe object of the research is landscapes of the urban ecosystem of the town of Vinnytsia. The purpose of the work is to investigate and evaluate the level of videoecological perception and geopotential sustainability of Vinnytsia and set the main risks to natural and artificial visual environment of the city. The paper deals with the method of calculation for the evaluation of videcoecological favourableness of the urban environment and methods of visual pollution control in the urban environment. During the research videoecological perception of the town of Vinnytsia was analyzed, the main environmental risks of the technosphere were identified and an evaluation of the sustainability of the urban environment of the city was made; the ways to optimize visual sensitivity of natural and artificial environment in the city were reviewed. A map-scheme based on experimental data and patterns of the range of videoecologiacal perception was made and its distribution among the territory of Vinnytsia was shown.
