Abstract:
The main purpose of this investigation was the monitoring of Zn and Cu levels in soils of central Greece over three consecutive years (2005 to 2007). Soil samples were analysed for available forms (after extraction with DTPA) and for total concentrations (after digestion with Aqua Regia) of Zn and Cu. A temporal variability, from 2005 to 2007, was observed, as an increasing of 25.5% in available Zn, 25.1% in total Zn, 209% in available Cu and 19.6% in total Cu concentrations were recorded. A spatial variability was also observed and illustrated by the respective thematic maps created using geographic information systems (GIS). Significant correlations among metals concentrations and soil physicochemical parameters were obtained and discussed.
