The article is devoted to the process of air pollution as a result of the production and application of paints and varnishes used in the construction industry. In the process of pollution in the air enters the polluting aerosol (toluene), which is a toxic substance. The whole process of pollution is considered step by step, where at each stage the contaminating aerosol changes its parameters of properties. The result of the analysis of the pollution process is a physical model and mathematical dependence describing the essence of this process.

The problem of negative impacts of various nature on the environment from the functioning of public facilities is currently particularly relevant. A special place among such objects is occuped by shopping and entertainment complexes representing a unique symbiosis of various zones. This makes them objects an extensive list of negative factors affecting the environment. At the first stage of the research to solve this problem we carried out a study of the existing scientific approaches to the assessment of the state of the environment and the selection of the scientific basis for subsequent research. The results obtained at the completed stage of the research can be used as the basis for improving the existing scientific base in order to minimize the shortcomings of the existing approaches.

The article is devoted to the analysis of the physical essence of the process of reducing air pollution for the woodworking shop of the enterprise serving the objects of urban construction, within the framework of the physical and energy approach. According to this approach, wood dust is considered from the position of the theory of dispersed systems, which changes its properties under the influence of external dispersed systems. The whole process is gradually illustrated by a physical model of the process of reducing air pollution, as well as a scheme of transformation of the dispersed system (dust aerosol) in the process of reducing air pollution.

The authors (of the research) suggest choosing the most eco- and energy-efficient engineering system in order to purify the air of the dyrer drums dust. The choice should be made on the basis of the analysis and evaluation of the dust properties and determination of the control methods of the dust aerosol stability, which, eventually will ensure its effective destruction as a dispersed system in the air purification process.

The authors propose to choose the system of air purification from grain dust, which has the maximum ecological efficiency and energy efficiency, based on the study of the properties of this pollutant. Investigation of the grain dust parameters of the properties of the dispersed phase and dispersion medium, as well as energy parameters will affect the stability of the aerosol, i.e. its ability to resist external influences. Changing the stability of the grain dust aerosol and, ultimately, its destruction due to the separation of the dispersed phase and the dispersion medium, is the purpose of the development of air purification system.

While the features of sources of acoustic impact as ground handling and flight operations. Assessment of acoustic impact on the adjoining residential zone under construction or reconstruction of airport complexes, according to the authors, involves several stages. The implementation proposed by the authors of the stages of the assessment of acoustic impact will allow to identify the zones of acoustic discomfort and plan a set of measures aimed at reducing noise in those areas and thus enhance environmental validity under construction or reconstruction of airport complexes.
