Actuality. Studies of soil pollution assessment are based on scientific principles that define a complex system of environmental safety management in the context of increased exposure to sources of secondary dust pollution of the atmosphere. To ensure environmental safety under conditions of high levels of dust pollution, it is necessary to apply and improve the relevant models. Among the many types of environmental pollution, dust pollution of the atmospheric air and the deposition of harmful substances on the soil are particularly dangerous. This pollution can take two forms: direct emissions from industrial enterprises (primary) or the formation of secondary pollution through physical and chemical processes in places where dust-like waste is stored. Fine waste after air purification with dimensions of less than 100 microns is particularly hazardous. In modern environmental monitoring and assessment of soil pollution, special attention is paid to remote methods that allow for more effective monitoring of the impact of human activity and solving environmental problems. The use of unmanned aerial vehicles is one such method that has positive results. The purpose of the article is to solve the scientific problem of improving aerospace methods based on unmanned aerial vehicles (UAVs) for monitoring and assessing the quality of soil pollution. The object of the study is the use of aerospace tools for monitoring and assessing the condition of soil cover. To achieve this goal, the following tasks have been defined: to study the current state and ways to improve the efficiency of UAVs in the system of environmental monitoring of soils; to develop models of environmental assessment; to analyze existing approaches to the use of aerospace assets for monitoring and assessing the state of soil cover. Conclusions: a methodological approach based on a modified method of the comprehensive assessment of the level of technogenic hazard of industrial facilities is proposed to assess the state of environmental safety in conditions of intense dust pollution of the atmospheric air.

The article considers the possibilities of using geoinformation systems and remote land sensing systems in detecting the development of degradation processes of the soil cover. The use of satellite technologies for the detection of soil degradation and timely response to these processes requires timely information and the availability of a database. The environmental safety system is aimed at forecasting and preventing emergency situations of technogenic and ecological nature. It includes the development of forecasting models and algorithms, as well as the allocation of resources to take immediate action in the event of such situations, as well as information about potential hazards, risks and possible consequences. With the use of geodetic surveying and computer processing of the surveying results, the coordinates of land plot plans were obtained. Satellite images were used to obtain data on changes in soil cover over a large area and on a large scale. Aerial photographs reveal small changes in soil structure, indicating signs of erosion or other degradation processes. Digital electronic terrain maps provide geographic information about an area, including geological and geomorphological features. They are used to combine other data, such as satellite images or aerial photographs, and create a comprehensive picture of the state of the soil. In the course of research, the system of ecological monitoring of soil cover using the method of infrared spectrophotometry was improved. The method of physico-chemical analysis of soil samples is substantiated and the dependence between the state of soil contamination by individual chemical elements and their genesis is established. The creation of a computer database and the use of space images in combination with other geo-information technologies really allows for effective monitoring and analysis of soil degradation and other agricultural objects.
