The article presents the results of laboratory studies of the effect of volume concentration of suspended particles in contrast to the luminous slits image obtained by smartphone cameras of SAMSUNG Galaxy A3 and Honor 8 Lite. Experimentally it was found that a pattern of change in contrast to the luminous slits image from the volumetric concentration of suspended particles appears under ambient light. The pattern of contrast change can be expressed by an exponential function. The correlation coefficient is 0.97. Cigarette smoke was used as suspended particles.

Introduction. A promising direction of nature management, which allows avoiding the degradation of the biosphere, is the implementation of economic and other activities with minimal impact on nature. The state of health of the population is influenced by a complex of environmental factors. The load of atmospheric air is perceived by the respiratory organs, vision, and the skin. Water influences in the form of precipitation, both drinking and recreational. The direct effect of soil on human health occurs through direct contact with the skin, inhalation and oral intake into the body. Green spaces have a significant impact on the quality of urbanized soil, water and air, as well as the health of residents. The main aspect of environmental protection and maintaining a favorable microclimate in settlements is the preservation and recreation of the “green” fund. Materials and methods. Systematic analysis of scientific literature, statistical data, regulatory documents. Results. The dependence of Russians on the influence of sanitary and hygienic factors of the environment is shown. The dynamics of the indicator “green spaces” in the urban environment quality index for the group “largest cities” is considered. On the example of St. Petersburg, the satisfaction of residents with the sphere of landscaping the territories of city districts is shown. It is proposed to conditionally divide the main problems of the development of “green” infrastructure into groups. The conceptual principles that constitute the methodological basis for the creation of a “green” frame of a settlement have been determined. Formed a group of criteria for assessing the “green” infrastructure, which are indicators of technical progressivity and social significance, with predictive ability and consistency. Conclusions. The necessary and sufficient amount of green spaces, normalizing the quality of the urban environment, can have a positive impact on the physical and mental health of residents. Strategic planning for the development of the “green” infrastructure of the settlement, ensuring the viability of the green frame, should take into account all its elements and include landscaping of land plots adjacent to the territories of multi-family dwelling.

Introduction. The analysis of practical and theoretical experience shows a significant impact of “green” roofs to reduce the concentration of PM2.5, but the existing methods do not allow in calculating the concentration of pollutants to take into account the dust absorption capacity of the plantations in respect of PM2.5 particles. The aim of this work is to create a method to justify the effectiveness of “green” roofs to reduce fine PM2.5 particles to increase the environmental safety of the urban environment (as applied to the RF) according to the proposed typology based on the developed mathematical model. Materials and methods. Analytical generalization and systematization of scientific research, mathematical methods were applied. Results. The developed method represents a sequence of 29 actions, the implementation of which will lead to a conclusion about whether to green the existing building roof, and whether it will be effective in terms of reducing the concentration of fine particles PM2.5 in the air environment. Performing the actions involves performing a calculation in accordance with a mathematical model. The final numerical result of this methodology will be the average for the summer period of time daily accumulation of dust on the surface of the “green” roof in grams. The greater the value, the more effective the device “green” roof in the selected location in terms of improving the environmental safety of the city. Conclusions. The developed method has practical significance and can be used in various urban planning scenarios, when it is necessary to evaluate numerically the effectiveness of the “green” roof on a particular building, which is carried out at the design stage by comparing different options for placement of “green” roofs and choose the best of them (for which, other things being equal, the average daily dust accumulation PM2.5 for the summer period in grams on the surface of the “green” roof will be the greatest) in terms of ensuring environmental safety.
