The influence of past metallurgical activity on the concentration of heavy metals in the soil/grass system in Sibenik (Croatia)
Degree of heavy metal pollution in soil caused by a former Ferromanganese Plant (FMP) and aluminium factory was investigated and the potential of metal mobility and bioavailability was estimated. Elemental concentrations in soil, vegetation and soil extracts were determined by EDXRF. In the nearest vicinity of the factory, soil concentrations ranged as follows: Mn 12,700-342,000 ppm, Zn 200-1090, Cu 50-440, Ni 60-330, V 60-410 and Pb 24-320 ppm. Significantly higher concentrations of V, Ni, Cu, Zn and Pb compared with control samples were also found in the soil samples taken in the vicinity of aluminium plant.
