    Monitoring the state of environmental safety using phytoindication methods to ensure sustainable development of a technologically loaded city Kremenchuk

    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.

    Condition and quality of the air of the Chernivtsi region

    The question of rating of the condition of the air in the regions of Ukraine is very relevant. An important component is the choice of the optimal rating method. The purpose of the work is to review methodological approaches to the rating of the condition of atmospheric air (on the example of the city of Chernivtsi). The results of the calculation of CAPI and I5 showed that the maximum was noted in 2017 due to abnormally high concentrations of phenol, the minimum was in 2018. The value of I5 is fully correlated with the value of CAPI, which means the expediency of using I5 in particular for rating. According to the value of I5, the quality of the air is characterized by the level of "slightly polluted". Nitrogen dioxide, hydrogen fluoride and formaldehyde were included in the "three" priority pollutants. The value of In changes similarly to CAPI. In comparative analysis for individual regions, it can be used as an alternative indicator. The dynamics of changes in the index AQI for individual pollutants are similar to their time course. At index values of 100%, the air quality is characterized as "poor", although this corresponds to the level of the MRS. According to indicators of sustainable development in the "Ecological systems" category, a significant deterioration of circumstances is noted, for the "Environmental load" category - a significant improvement in circumstances is noted. The condition of the air underwent positive changes until 2018. Since 2019, indicators have deteriorated.
