Assessment of phytoremediation potential of some cereals under the action of mine wastewater of a mining enterprise

The article presents data on the accumulation of pollutants in the green vegetative mass of four cereal species, Festuca arundinacea Schreb., F. rubra L., Lolium perenne L. and Poa pratensis L. under regular exposure to mine wastewater of a mining enterprise. The changes in the morphological and physiological parameters of plant development were assessed using the PlantEye F500 installation. The most informative parameters were: digital biomass and normalized chlorophyll index (NPCI). It was noted that at the initial stages of exposure to wastewater, growth processes are activated, which decreases after 21 days of plant cultivation. Photosynthetic activity was maintained at a high level throughout the experiment. The most promising species with a high ability to accumulate pollutants and resistance to technogenic impacts were identified, which can be recommended for the creation of phytopurification systems.
