Abstract
As the plants mostly determine the environment of ecosystems, the substantiation of phytotoxicological risk assessment is extremely relevant. The purpose of the study was to rank metals and plants by metals concentration in the phytomass in natural ecosystems of Goloseevo-Feofanivska and Koncha-Zaspivska green zones in Kyiv. The phytotoxicological classification of metals by their concentration in plants in natural ecosystems has been obtained. The algorithm of the metals ranking in four classes of danger is proposed. It was revealed that the highest level of concentration in plants was for copper, the smallest - for cadmium and cobalt. Zinc, which is an important physiologically necessary trace element, and lead, whose physiological role is not thoroughly investigated, relate to the middle phytotocosicological class. Plants with low and moderate metals concentration in phytomass were: Carpinus betulus L., Acer platanoides L., Quercus robur L., Prunus padus L., Salix caprea L., Tilia cordata Mill., Sambucus nigra L.. Plants with high metals concentration in phytomass were: Tussilago farfara L., Anemone ranunculoides L.. Assignment the metals and plants to phytotoxicological classes will allow not just only to characterize the hazard of metals for plants, but to forecast the reaction of plants to metals influence in nature ecosystems
