A different behaviour characterized the two arable soils under investigation as regards the content of copper, being one of them sampled under orchards. Since many years, treatments with fungicides based on copper salts have been widely applied, resulting in a considerable build-up of water and LMWOAs extractable Cu. Therefore, largest standard deviations caused a lack of significance between copper means. In the lower horizon highest metal concentrations were observed in city park soils, except for Cd. LMWOAs extraction showed a different mobilization of metals compared to water extraction. Table 3 - Average water and LMWOAs extractable metals from city park (CP) and arable (AR) soils (g kg -1 ).

plants. Besides metal chemical speciation, chemical properties of the soil, such as texture, organic matter content, cation exchange capacity, salinity, pH and redox potential are the main parameters controlling plant uptake of heavy metals (Sauerbeck and Hein, 1991, Davies, 1992). Significant effects of soil texture and particle-size distribution on mobility of heavy metals in soils have been reported (Qian et al., 1996; Meers et al., 2007). In order to give an insight into the potentiality of the two single extraction procedures to reflect some measure of the pseudo-total soil content, data sets were divided into soils with sandy texture (pinewood soils) and sandy loam and silty loam texture (city park plus arable soils). In table 4 are displayed Spearman correlation coefficients () between the extracted metals by water and LMWOAs and pseudo-total soil content of heavy metals as determined by aqua regia (data shown in Vittori Antisari et al., this conference). Based on the weaker extraction procedure, a higher relative positive correlation of pseudo-total concentrations of Cu, Zn, and Cd of pinewood soils can be derived compared to the city park plus arable soils. For Pb, the correlation was found to be positive for pinewood soils but at a lesser probability level than for Cu, Zn and Cd. No Pb correlation was achieved for city park plus arable soils because over than 60% of the samples were below the detection limit of the method.
