The problem of air pollution with environmentally hazardous dust with a particle size of up to 10 microns at plants for the production of thermal insulation materials is considered. The purpose of this work is to study the dispersed composition of dust in the production of insulation materials (such as mineral wool), and to determine the effectiveness of the existing gas cleaning equipment, which traps pollutants. The dispersed composition of the dust generated at the plant for the production of thermal insulation materials, and the dispersed composition of the dust collected by the dust-cleaning equipment was investigated. Experimentally and with the use of computer programs, it has been established that the efficiency of extracting fine dust from dust- cleaning equipment does not exceed 78%. It is established that the dust of mineral wool entering the aspiration system is dominated by particles with a size from 2.5 microns to 25 microns. Dust with a SiO2 content of up to 70%, which is released during unloading and transportation of raw materials (dolomite, basalt), enters the atmospheric air without purification. At the same time, particles with a size of up to 60 microns and up to 72 microns dominate in atmospheric air, respectively. The main characteristics of the dust necessary for the objective selection of dust-cleaning equipment are determined.

Industrial development has brought about not only rapid economic growth, but also serious environmental pollution in China, which has led to serious health problems and heavy economic burdens on healthcare. Therefore, the relationship between the industrial air pollution and health care expenditure (HCE) has attracted the attention of researchers, most of which used the traditional empirical methods, such as ordinary least squares (OLS), logistic and so on. By collecting the panel data of 30 provinces of China during 2005–2016, this paper attempts to use the Bayesian quantile regression (BQR) to reveal the impact of industrial air pollution represented by industrial waste gas emission (IWGE) on HCE in high-, middle-, low-income regions. It was found that double heterogeneity in the influence of IWGE on HCE was obvious, which revealed that people in high-, middle-, low-income regions have significantly different understandings of environmental pollution and health problems. In addition, the BQR method provided more information than the traditional empirical methods, which verified that the BQR method, as a new empirical method for previous studies, was applicable in this topic and expanded the discussion space of this research field.

The aim of the study was to develop a promising filtering device for cleaning industrial premises from fine dust of aerosol particles, providing increased cleaning efficiency and safety. A high degree of purification is guaranteed by electrostatic filters of the order of 90-95%. However, they also have a number of disadvantages that require improvements in the operating principle and design. In connection with the development of "clean" technologies in medicine, in the electronic and food industries, this direction of research is relevant.

Abstract Background: China's industrial parks are areas where energy consumption is relatively concentrated and air pollution is relatively serious. Air pollution threatens the living environment, health and even life of the residents around the industrial park. Therefore, the measurement of air pollution loss and its application have been raised, and gradually become an important problem to be solved.Results: In order to explore the measurement method of environmental pollution loss from energy consumption waste gas emission in industrial parks, this paper, based on literature review, draws lessons from the latest research results at home and abroad, fully considers the actual situation of energy consumption waste gas emission and environmental pollution control in China's industrial parks, and constructs the shadow price measurement model of environmental pollution loss from energy consumption waste gas emission. Taking Nanjing MV industrial park as an example, the application test of environmental pollution loss of energy consumption waste gas emission is carried out by using the relevant statistical data of the park, and the validity of the model is verified.Conclusions: The results show that the shadow price model is more effective for the Measurement of environmental pollution loss of exhaust gas emissions from energy consumption in industrial parks. The research results are of great significance to guide exhaust emission enterprises to strengthen environmental pollution loss control and support local governments to formulate energy consumption and exhaust emission standards and relevant policies for industrial parks

Fine dust: (PM2.5, PM10) is a priority pollutant that contributes to the development of numerous dis-eases in urban areas. The purpose of this scientific work is to study the dispersed composition of dust parti-cles on the leaves of apricot trees (Prúnus armeníaca) in the residential zone of Volgograd. The novelty of the work lies in the study of the dispersed composition of dust particles on the leaves of apricot trees (Prúnus armeníaca) in the residential zone in the city of Volgograd near the construction industry enterprise, me-chanical engineering, leather production and railway transport line in comparison with the conditionally clean (control) zone of the SNT “Orocenets” ”(Sovetsky District, Volgograd) from the standpoint of random functions expressed by integral distribution curves of the mass of particles over their equivalent diameters. As a result of the research, the dispersed composition of dust on the leaves of apricot trees (Prúnus ar-meníaca) in the residential area of Volgograd was revealed. Fine particles were found: PM2.5, PM10 in each of the studied points, which by their values, both in their number and mass fraction, significantly exceed the data on fine dust in a conditionally clean area (control) in the SNT “Oroshanets” (Sovetsky district Volgo-grad), which creates certain environmental risks for local residents. The dispersed analysis of particles from the standpoint of random functions in the future will allow with a sufficiently high degree of accuracy to pre-dict the dust content of urban atmospheric air in the range of monthly and / or seasonal average values compared to the traditional measurement of fine dust concentration in atmospheric air of the urban environ-ment as the maximum single or daily average. At the same time, further studies of dust on the leaves of plants in an urban environment, namely, the study of the density of its sedimentation, will also reveal a group of ur-ban plants that are best suited to retain PM2.5 and PM10 on leaf plates in this region, which can significantly increase the quality of the atmospheric air of the urban environment and be of a recommendatory nature for the state-owned landscaping services of the city of Volgograd when improving the green areas of a megacity.

The paper presents the composition of atmospheric air as a mixture of gases that make up the solid and variable components, and the definitions of air pollutants are referenced. Gaseous and solid pollutants (dust) of the atmospheric air have been defined. Dusts were divided according to various criteria and their properties were given. Exemplary courses of immission of the fraction of solid particles are given, indicating a strong dependence of the immission on the seasons, days of the week and day and night. The sources and characteristics of artificial and natural pollutants in the atmospheric air are presented. It has been shown that the main sources of anthropogenic pollution in addition to industry and the automotive industry. Cars are a source of gaseous and particulate pollutants PM, and they also emit pollution from brake and clutch lining wear, as well as from tire and road wear. The main sources of natural air pollution were discussed, including volcanic eruptions, fires in landfills, forests, steppes and sand storms, as well as mineral dust (road dust) carried from the ground by vehicles. The properties of road dust are discussed: chemical and fractional composition, density, dust concentration in the air. It has been shown that the two basic components of the dust, silica and corundum, whose share in dust reaches 95%, also have the highest hardness, which may have a decisive influence on the wear of engine components. Various valuesof dust concentration in the air were presented depending on the type and condition of the ground and the conditions of use of vehicles.
