The aim of this study was to evaluate the potentially toxic elements (PTEs) concentrations along the soil profiles in areas with different anthropogenic impact. The study area is in the Ravenna Municipality, a complex territorial system including natural zones, heavily industrialized areas and extensive agricultural land. Three zones with different environmental impact were identified: the San Vitale Pinewood, a natural reserve close to the industrial area (four soil profiles); a public garden within Ravenna city, mainly affected by traffic pollution (one soil profile); the farm "Luigi Perdisa" located immediately northwards of Ravenna was selected because of the use of fertilizers and also it is subjects to various types of atmospheric deposition (one soil profile). The total concentration of Ba, Cr, Cu, Cr, Ni, Pb, Zn was determined by X-ray fluorescence spectrometry (XRF) and the pseudo total concentration with aqua regia digestion (AR) and ICP-OES analysis, in order to evaluate the extractability of these elements in soil profiles. The data showed a significant increase of some PTEs (Cu, Pb, Zn) in the top soil compared to bedrock. In Ravenna urban park, Pb and Zn concentrations exceeded the threshold values established by current Italian laws for soils of "public, residential and private areas" (D. Lgs 152/2006). The correlation between the concentration values of top and subsoil highlighted that some PTEs, such as Cu, Pb and Zn, had an anthropogenic origin and were mainly linked to the deposition of airborne pollutants, while other elements (Cr and Ni) had a lithologic origin.

Abstract
The aim of this study was to evaluate the potentially toxic elements (PTEs) concentrations along the soil profiles in areas with different anthropogenic impact. The study area is in the Ravenna Municipality, a complex territorial system including natural zones, heavily industrialized areas and extensive agricultural land. Three zones with different environmental impact were identified: the San Vitale Pinewood, a natural reserve close to the industrial area (four soil profiles); a public garden within Ravenna city, mainly affected by traffic pollution (one soil profile); the farm "Luigi Perdisa" located immediately northwards of Ravenna was selected because of the use of fertilizers and also it is subjects to various types of atmospheric deposition (one soil profile). The total concentration of Ba, Cr, Cu, Cr, Ni, Pb, Zn was determined by X-ray fluorescence spectrometry (XRF) and the pseudo total concentration with aqua regia digestion (AR) and ICP-OES analysis, in order to evaluate the extractability of these elements in soil profiles. The data showed a significant increase of some PTEs (Cu, Pb, Zn) in the top soil compared to bedrock. In Ravenna urban park, Pb and Zn concentrations exceeded the threshold values established by current Italian laws for soils of "public, residential and private areas" (D. Lgs 152/2006). The correlation between the concentration values of top and subsoil highlighted that some PTEs, such as Cu, Pb and Zn, had an anthropogenic origin and were mainly linked to the deposition of airborne pollutants, while other elements (Cr and Ni) had a lithologic origin.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
