Examine the contents of the elements of the group of heavy metals in samples 18 meadow plant species and soil basal space. In soils root space is determined by significant fluctuations of total concentrations of heavy metals. Identified accumulative opportunities meadow species relative to the TM in natural meadows in the conditions of high technogenic load. Based on the coefficients of accumulation established types of «indicators» and «exclusive», which can be recommended as effective phytoremediation. For grassland species confirmed the species specificity of accumulative opportunities plants relative to the TM: Filipendula ulmaria, Scirpus sylvaticus (гигрофитные виды), Agrostis tenuis и Helichrysum arenarium. Hygrophytic species of floodplain meadows, xerophytic species in dry accumulate chemical elements the same, regardless of the geographical location of meadow ecosystems. For these plants is characterized by the accumulation of mobile essential elements strontium, copper, manganese.
