TY - JOUR N2 - The aim of the study was to estimate the influence of metallurgical slag on heavy metal concentration in tree species. The research included pH-reaction and conductivity of slag samples, heavy metal content (Pb, Zn, Cd, Cu, Ni) in slag, needles and leaves samples. The waste material is covered by vegetation and fulfils a soil function. The vegetation is self-sending. The plant cover being a result of natural succession consists of weeds, grasses, perennials, bushes and trees. Dominant tree species are birches and willows as well as poplar and pine. In slag samples are observed the raised concentration of cadmium, lead and copper. The low content of zinc is surprising. In tree material observed excessive heavy metal concentration especially lead and cadmium. Their accumulation is undoubtedly depended on tree species, but in this case heavy metal content in plant samples is a result of their presence in slag material. The higher heavy metal content in slag results the higher concentration in needles and leaves (probes S1 and S2, T1 and T2). Exception to this rule is the birch - probe B,, but in this case the pH is crucial. In samples with pH over 6.8 heavy metal mobility, their solubility and phytoavailability decrease. pH below 7 results in higher trace element uptake in plants.
