چکیده

The article explores the potential use of Aesculus hippocastanum (horse chestnut) as a phytoremediator under conditions of artificial soil contamination by heavy metals in an urban environment. The research was conducted in Almaty City, where a significant excess of the maximum permissible concentrations of heavy metals, particularly lead has been detected. The study involved growing horse chestnut seeds in soils with varying contamination levels and treating them with solutions of toxic metals (Pb, Cd, Hg, etc.). Morphological and anatomical changes in the plants were analyzed, and levels of physiological stress were assessed. The results confirmed the high ability of A. hippocastanum to accumulate heavy metals, making it a promising bioindicator and a practical tool for ecological restoration of urban areas.
