Principal Investigator: Tomasz Bajda

Project ID: N N525 461236
The aim of the project was to determine the form of lead, zinc, cadmium and arsenic in soils degraded by mining and zinc-lead metallurgy in Upper Silesia and to assess the determine of reclamation treatments on their mobility. Soil samples collected and used in experiments from the vicinity of Zakład Górniczo-Hutniczy „Bolesław” in Bukowno are samples of contaminated soils in which zinc, cadmium and lead are found, which are easily accessible to living organisms.
The results of the leaching and phytotoxicity tests allowed to determine the effectiveness of mineral sorbents and phosphate fertilizers used in the immobilization of metals in soils. Based on the ranking, it was determined that the highest effectiveness of the reduction of leachable and phytoability contents of Zn, Pb and Cd in soils showed: ammonium phosphate, Polifoska 15 and bog iron ore. The experiment of the influence of temperature on the effectiveness of immobilization of metals in soils proved that Zn, Pb and Cd leaching in winter conditions will not increase both in the soils treated with bog iron ore and phosphate ammonium. The conducted column test showed greater efficiency in the reduction of metals leaching from soils in the use of bog iron ore additives than ammonium phosphate. The performed experiments made it possible to choose optimal conditions for Zn, Pb and Cd immobilization in the studied soils. Two solutions are proposed. The first of these assumes the use of ammonium phosphate additions, while using As(V) phytoextraction. In this way, a high reduction in the leaching and phytoability of Zn, Pb and Cd will be ensured, and the treatment of soils from toxic arsenates will be possible. The second solution involves the use of bog iron ore additives in the process of immobilization of metals in soils. The tests confirmed that this sorbent is characterized by high the efficiency of reducing the leachability and phytoability of Zn, Pb and Cd. For applying this additive the results of the column experiment speak, in which its high efficiency is revealedlimiting the mobility of tested metals.
