The results of permeability and compressibility tests of the fly ash from Skawina Power Plant were presented in the paper. These tests were carried out in the aspect of its usage in filtration barriers in municipal and industrial waste landfi lls. It was stated that the tested fly ash can not be used for fi ltration barriers, mainly because of granulation and fi ltration criteria. Although, the addition of another soil or a hydraulic binding agent would improve its granulation and would increase impermeability.

Spiraea van-houttei (Briot.) Zabel has often been used for urban landscaping and for the biological recultivation of ash deposits in Serbia. This study examines its photosynthetic efficiency, water balance, and trace element content in the ‘Stara Zvezdara’ park in the city of Belgrade, in the fly ash deposits of the ‘Nikola Tesla – A’ thermoelectric power plant in Obrenovac, and at the Arboretum of Belgrade’s Faculty of Forestry. Site-dependent variations were found in the water saturation deficit, photosynthetic efficiency, Cu and Mn concentrations, and leaf damage symptoms. The higher water saturation deficit measured in the city park showed some difficulties in maintaining water balance due to Pb accumulation in leaves and the chlorotic damage caused predominantly by car exhaust pollutants. A photosynthetic efficiency (0.787) within the optimum range indicated the capacity of this species to tolerate the elevated concentrations of pollutants in the city air. However, the low photosynthetic efficiency (0.588) and the deficiency of Cu (2.380μg/g) and Mn (9.550μg/g) that caused leaf wilting indicated that the spiraea would probably disappear from the fly ash deposits in spite of a favourable water balance.
