Abstract
A critical analysis of the approaches to the development of a model for determining the concentration of hazardous chemicals (HC) in the atmosphere, which are the basis of computeraided environmental monitoring systems (CEMS) has been carried out. It has been established that the lack of effective functioning of the existing CEMS is determined by the imperfection of the models used to determine the concentration of atmospheric chemical concentration in the atmosphere. In addition, the organic disadvantage of such systems is their departmental affiliation and, as a result, the limited number of potential users. To improve the efficiency of the discussed class of systems, a concept of integrated use has been proposed, within the CEMS framework, elements of information and analytical systems for environmental monitoring, satellite image processing tools, geoinformation technologies, and also mathematical software for calculating the concentration of various types of atmospheric HCs. Building a CEMS based on this concept will provide an opportunity to significantly improve the efficiency of their functioning in the aspects of reducing the time for making decisions, as well as reducing the risk of making wrong decisions. The mathematical support of the CEMS is based on the “Gaussian” statistical model of HC emission, and is intended, along with geographic information technologies, to synthesize a geomodel of groundlevel atmosphere pollution by HCs. As an illustrative example, the situation of the release of chemical waste in the area of Bila Tserkva (Kyiv region, Ukraine) is considered. Theoretical results form the methodological basis for the implementation of the applied information technology for the creation, deployment and operation of a decision support system for eliminating the consequences of an emergency situation caused by the proliferation of chemical water in the atmosphere

The aim of research is increasing the efficiency of the process of determining the hazardous chemicals (HC) concentration in the atmosphere based on the improvement of the computer system for environmental monitoring
Summary
The negative impact of the environment on the state of human health, due to anthropogenic stress, has increased many times in recent years. CEMS are focused on a comprehensive assessment of the current state of potentially hazardous objects (PHO) [1] and emergency situations at these facilities related to environmental pollution by chemical waste [2, 3]. The currently used computer systems for monitoring air pollution have a number of drawbacks, which significantly reduce their effectiveness These disadvantages include, first of all, the focus on decision-making support only in extreme conditions, and, by virtue of departmental affiliation, the limited number of potential users of such systems. Access to the information of many users would allow to adequately assess the collective and the individual level of vulnerability, as well as significantly reduce the cost of operating atmospheric monitoring systems
