Annotation The paper presents some results of longitudinal research on iron, copper, zinc, nickel, mercury test in Populus balsamifera organs (leaf, root, bark) conducted in summer vegetative season in order to study some peculiar characteristics of the metals’ accumulation in urban environment conditions of Chita. The data on accumulation of heavy metals in above-ground and underground phytomass of P. balsamifera are analyzed. The comparison of metal content in organs of the species studied with maximum allowable concentration is presented. The study observed a barrier type accumulation of iron, copper, zinc, nickel, mercury. P. balsamifera is described as species concentrator of zinc. The analysis shows that the species studied absorbs heavy metals accumulating them in different organs. As a result, this promotes accidental metal excretion from the cycling of matter. The paper proves the role of this species in landscape gardening of Zabaikalsky krai cities and its use in biological environmental cleaning up from heavy metal pollution.
Key words environmental pollution, heavy metals, phytoremediation, species concentrator, maximum allowable concentrations.
