Poltoratskaya V. Environmental risk assessment of air pollution on the basis of measurements undertorch

The object of study - the risk associated with air pollution in the areas of influence of the industrial enterprises in their normal operation. The aim of the thesis are the patterns of distribution of ground-level concentrations of pollutants and the risk of human exposure. Methods: a stochastic approach to its research methods in probability theory, mathematical statistics and theory of reliability, as well as methods and deterministic laws of aerodynamics the surface layer of the atmosphere, describing the propagation of contaminants in it. Theoretical and practical results: environmental risk assessment model based on measurements undertorch implemented as an algorithm. The use of constructed models can use the results of research on the environmental risk assessment in the development of project documentation to assess the impact on the environment during the construction and reconstruction of enterprises, buildings and structures, including the organization of air monitoring, methods and means of control. Scientific novelty: first established using data undertorch measuring the patterns of distribution of surface concentrations of pollutants (during the normal operation of the enterprise) as a stochastic vector field, has been further developed a methodology to assess the level of danger from the point of emission of pollutants and groups of point sources on the basis of measurements of surface concentrations undertorch , developed a method for assessing the actual risk of air pollution in the zone of influence of the enterprises, which is characterized by taking into account the hygienic standards of short-term effects of air pollutants on human set of point sources of emissions, and taking into account the natural undertorch measurements of concentrations of pollutants using data undertorch measurements the actual risk of simultaneous displays human exposure to emissions of air pollutants from a point and a group of industrial point sources, depending on the concentrations of pollutants. The degree of implementation: risk assessment algorithms were tested on the example of a going concern; used to justify the improvement of the areas of air Dnepropetrovsk to adjust the "Program to reduce air pollution major pollutants by enterprises in 2008-2015", the methodology implemented by LLC "Geotechnology" in the learning process. Application areas: models can be used by the Ministry of Ecology and Natural Resources of Ukraine, in the environmental monitoring industry, to assess the impact on the environment in the design and construction of enterprises, buildings and facilities, research organizations in improving the environmental profile of methods of assessing environmental risk.
