O článku:
The ecological risk caused by the potential migration of potentially toxic elements (PTEs) during the recultivation of the abandoned uranium mining deposit in Mecsek in Hungary was estimated by developing a sample strategy. To study the effectiveness of soil covering layer in retardation of migration of PTEs (Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, P, Pb, and Zn) on the covering soil of deposit No.1, sampling locations were selected based on the results of the running monitoring program at the deposit No.1, where erosion wounding occurred during the recultivation. Top to bottom soil core samples (0–25, 25–50, 50–75 and 75–100 cm depths) and covering plant (grass) samples were taken and analyzed using Inductively Coupled Plasma – Optical Emission Spectrometer. Overall the results of the soil samples collected indicated that there is a possibility of migration of PTEs as water infiltrates from the top to the bottom of the deposit. Transfer factor, TF ≥1 for Cu might be an indication of trace elements’ availability to be taken up by the plants. The fractionation by sequential extraction of PTEs is still in progress which should give more information on their migration.
