The Ukrainian energy and fuel sector is highly dependent on mineral extraction. Hard coal accounts for 25-30% of mineral production in Ukraine. All processes, from coal mining to its use for energy, have a negative impact on the environment. One of these impacts is the accumulation of waste rock at an industrial facility, known as a coal dump. These dumps have a negative impact on all spheres of the environment. Coal dumps located in Western Donbas are characterized by a low pH level, a low level of specific electrical conductivity of the soil, a low level of nutrients and a high concentration of heavy metals. Among the main dangerous toxic elements are Pb and Cd, the concentration of which exceeds more than 2 times the maximum permissible concentration. According to the results of the study, it was established that Triticum aestivum has shown itself as a phytoremediator plant resistant to heavy metals such as Pb and Cd, which makes it available to further use for planting contaminated areas of coal dumps.
