    Ecological aspects of sustainable development have recently attracted the attention of scientists. The article is devoted to the control of ecological safety based on the study of the state of plantations in the city of Kremenchuk using the method of fluctuating leaf asymmetry as an indicator. The research was conducted in recreational, residential, transport and industrial areas. It was found that the condition of green areasin the city of Kremenchuk is heterogeneous and depends on the level of anthropogenic pressure. Plants growing near traffic routes and in industrial areas are much weaker than those growing in recreational areas.. The main indicator of plant condition in the study was the fluctuating asymmetry of the leaf blade of pyramidal poplar and hanging birch. It was found that the integral values of this indicator differ in different parts of the city with different intensities of anthropogenic impact, with the maximum values observed in industrial and traffic zones where there is an intense impact of pollutants. The results of the study confirm the unfavourable ecological condition of certain areas of the technologically loaded city of Kremenchuk, and also indicate the importance of environmental monitoring of pollution and development of measures to improve the condition of green areas. The results of the study can be used to improve the methodology and theory of ecological safety and urban environmental protection in order to preserve and restore plant populations in cities.

    Modeling and forecasting of the state of the environment in the waste management and management system consumption of Kremenchuk urban territorial community in Wartim

    We consider waste management and management as an area of ​​ecological safety. As a result of the study, the ecological aspects of this branch of activity were analyzed on the example of the operation of the operating MSW landfill in the city of Kremenchuk. The prospective direction of the field of waste management in the region, as well as the state of its financing, are taken into account. Such dangerous factors in the operation of the municipal landfill for the environment as: pollution of groundwater and open dumps of the landfill have been identified. The chemical composition of the leachate formed in the body of the landfill was evaluated and the concentrations of pollutants were compared with the permissible values ​​in wastewater discharged to the city sewer. Priority measures for landfill reclamation were proposed. We analyzed solid household waste landfills from the point of view of resource-energy saving, as an alternative source of energy thanks to the use of generated biogas, as well as extracted secondary resources.
