This article discusses the results of studies of selected areas, using bio-indication, namely the level of asymmetry of morphological systems of the black poplar (Populus nigra) tree. In assessing the state of the soil components in the environment, the study has used vegetarian objects of which the soil is a substrate. The document adds that soil contamination affects the state of green plants, so the various plant indicators could also be used to determine the degree of contamination of the overall ecological environment in the study area. The paper promotes bio-indication as a morphological method for examining the integrated biological characteristics of the state of the environment. It adds that the level of asymmetry fluctuation (measurements of the sheet) is sensitive to the action of chemical contamination and increases in response to anthropogenic pressure. To make the review more objective, the blueprint recommends the application of various bio-indicative methods in combination with other methods of determining the environment’s current condition. As an added element, the chemical analysis covers the soil and green space, while at the same time it examines the levels of heavy metals in the ’soil-plant’ system. The objective of the analysis is to enable the reader to assess the nature of soil-plant migration and redistribution, and its accumulation in specific organs of plants and soil horizons. In parallel, it identifies the structural and functional features of different types of soils and plant species as participants in the development and self-purification of the urbo-ecosystems.
