PECULIARITIES OF SOME HEAVY METALS ABSORPTION BY WOODY PLANTS IN CONDITIONS OF URBAN ENVIRONMENT
The article presents the results of the research devoted to the accumulation of metals by woody plants in the urban environment conditions. Species specificity of zinc and chromium absorption is revealed. Accumulation factor and translocation quotient for each species have been calculated. Metals' accumulation by woody species has been observed according to the barrier type. The results of the research can be used for selection of the woody plants species during planting of greenery in cities. In July 2009, there have been selected 36 soil samples and 145 plant samples (leaf, root, bark of the stem) of woody plants species commonly used in urban greening: Populus balsamifera L., Сaragana arborescens Lam., Ulmus pumila L., Malus baccata (L.) Borkh.
