The aim of research is to develop a methodology for assessing the properties and behavioral characteristics of toxic pollutants, that will allow to examine the nature of the change of stability, controlling it. We systematized property parameters and energy parameters of pollutants, investigated characteristics of their behavior in the conditions of urboecosystem. We proposed a method that allows to assess the behavior of the aerosol stability, controlling the behavior of toxic pollutants in order to reduce their stability and, ultimately, to reduce air pollution.
In the given article the authors offer an evidence-based technique for the solution of the problem of assessment and choice of the most ecologically effective and energetically economic technologies of air purification of toxic components of the departing and exhaust gases of objects in the conditions of urban environment. The technique development included consideration of a hydrodynamic method of flue gases purification of the toxic polluting substances on the basis of studying the physical features in course of the process, mathematical description of the method by criteria of ecological efficiency and energy efficiency parameter. At the final stage of the conducted research the technique of the assessment and choice of the most ecologically effective and energetically economic technologies of toxic components of the departing and exhaust gases of objects cleaning in the conditions of urban environment provided with algorithm for its realization has been developed.
Abstract. Sanitary city cleaning is one of the most important sanitary and hygiene events, promoting protection of human health and environment. Sanitary cleaning includes a complex of works on solid municipal wastes (SMW) collection, transportation, deactivation, processing and burial and urban territory cleaning. In order to improve the works on SMW handling and the ecological state of urban territories, enterprises of public and utility sphere operate, organizing all types of works listed above. However, processes of waste creation and accumulation are dynamic in their essence. Process of waste transportation depends on various factors. Management of this process often demands urgent correcting of earlier taken decisions or even cancellation of those decisions. Reasons of such changes could be of the most unpredictable nature, for example, traffic jams on motorways, vehicles breakage, repair works on the roads, etc. Thus, the enterprise (or, more precisely, the facilities serviced by it, the transport) acting with the purpose of providing ecological safety to urban territories, is the source of E pollution by itself. One of the main stages of SMW handling is waste transportation, where sources of E pollution with wastes (accumulation points) and enterprises on handling SMW are involved. That is why the solution of the pressing issue of increasing ecological safety of urban territories on the basis of ecologically efficient and energetically economic selection of engineering-ecological system of SMW transportation is represented in the article.
The article is devoted to solving the actual problem of creating a comfortable urban environment in the climatic conditions of the southern cities of Russia. The environmental safety of urban areas in the steppe zone can be ensured by forming belts of the «green belt» of the city, based on the use of specific functions of green spaces. The aim of the work was development of an integrated design method for the «green belt» of the city on the example of the territory of Rostov region, based on the analysis of the urban ecological situation, specificity of the regional range of perennial vegetation with the selection of plants that have environmental tolerance to man-made territory. The proposed technique can be used for other physiographic zones of the territory of the Russian Federation on the basis of selection and ranking of environmental and city-forming criteria for designing the «green belt».
Abstract. Each type of wastes of different aggregate states coming into the environment from various sources is characterized by certain set of parameters of qualities determining in the future the possibility of their secondary use. The article represents results of innovative research in the sphere of broadening of opportunities of use of construction wastes as secondary material resources. Parameters of qualities of construction wastes created in the process of technological processes at the enterprises of construction industry have been researched and classified. Construction wastes and their qualities are represented from the position of the theory of stability of disperse systems. Physical essence of processes and events was chosen as the main classification criteria in distribution of parameters of qualities of construction wastes by groups. Parameters of qualities of construction wastes are represented for disperse phase and dispersion medium.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
