Remediation potential of forest-forming species in the reclamation planting.

The aim of the research was to study the features of the accumulation of heavy metals elements group by assimilation apparatus of coniferous and deciduous woody plants. We registered low bioaccumulative coefficients of Black locust regards chromium, antimony, and tin. We also determined that the Robinia leaves could accumulate Sb and Sn while in small concentrations and the Crimean pine needles could accumulate Sb and As in in the lowest concentration. The Mangan fraction that translocated to the was high for both tree species and more higher concentration was fixed in the Crimean pine. The average content of Lead was 209.11 kg·ha-1 for Crimean pine in all age groups, while for the Black locust is was only 15.52 kg·ha- 1 that was by 13.5 times less. We determined large concentrations of Zinc in the Robinia leaves that was gradually decreasing with tree age. We revealed small contamination of Zinc in the Crimean pine with peak values of accumulation in the second age group of this species. We did not fix the definite trend of redistribution and accumulation of copper towards the tree species and age. For the Black locust the minimum content in green mass was determined for Cr and Sn. In general, the leaves fraction of the aboveground phytomass per unit area is able to accumulate the inorganic contaminants, which is ranged from 1.46 to 2134.35 kg·ha-1 for the Crimean pine and from 4.42 to 441.08 for the Black locust.
