“…The absence of increased Fe solubility in the rhizosphere may be explained, in part, by the relatively high uptake rates of the Fe–PS complex related to the preferential uptake mechanism for this complex (Römheld & Marschner, ; Gries et al ., ). It can therefore be expected that other unidentified DOC components also contributed to the observed increase in metal solubility, with Cu being known to show a particularly high affinity for soil organic matter (Oorts, ).…”

Root exudation of phytosiderophores from soil‐grown wheat

For the first time, phytosiderophore (PS) release of wheat (Triticum aestivum cv Tamaro) grown on a calcareous soil was repeatedly and nondestructively sampled using rhizoboxes combined with a recently developed root exudate collecting tool. As in nutrient solution culture, we observed a distinct diurnal release rhythm; however, the measured PS efflux was c. 50 times lower than PS exudation from the same cultivar grown in zero iron (Fe)-hydroponic culture.Phytosiderophore rhizosphere soil solution concentrations and PS release of the Tamaro cultivar were soil-dependent, suggesting complex interactions of soil characteristics (salinity, trace metal availability) and the physiological status of the plant and the related regulation (amount and timing) of PS release.Our results demonstrate that carbon and energy investment into Fe acquisition under natural growth conditions is significantly smaller than previously derived from zero Fe-hydroponic studies. Based on experimental data, we calculated that during the investigated period (21–47 d after germination), PS release initially exceeded Fe plant uptake 10-fold, but significantly declined after c. 5 wk after germination.Phytosiderophore exudation observed under natural growth conditions is a prerequisite for a more accurate and realistic assessment of Fe mobilization processes in the rhizosphere using both experimental and modeling approaches.

“…According to Oorts [39], copper is found in soil mainly as Cu 2+ and tends to bind with organic matter. Most soil-soluble Cu (even as much as over 90%) is found in complexes with dissolved organic matter.…”

This study aimed to determine the possibility to increase the the effect of different amendments (compost, bentonite and zeolite) on the shoot yield and the concentration of trace elements in shoots of maize (Zea mays L.) on soil contaminated with Cu. The yield of shoots and concentration of the trace elements in shoots of maize depended on Cu dose and amendment incorporation into the sandy soil. Cu-spiked soil caused an increase the yield of shoots (only to 100 mg Cu/kg of soil), in the concentration of Cu, Co, Mn, Ni and Fe in shoots of maize and, to a smaller degree, in the concentration of Zn and bioconcentration factor (BCF) of all elements except copper, compared to the control soil without Cu. Under the influence of 150 and 200 mg Cu per kg of soil, a decrease in yield of shoots of maize was observed. Compost, bentonite and zeolite increased the yield of shoots and reduced the concentration of Cu, Co, Mn, Fe and Zn in shoots of maize. Bentonite had a more positive effect than compost and zeolite on the yield of shoots and the concentration of Co, Mn and Zn in shoots of maize. The effect of these amendments on the Cu and Fe concentration in shoots of maize was reverse. A reverse effect of these amendments (especially bentonite and zeolite) on the Ni concentration in plants was observed. The amendments applied to soil, especially compost, increased the BCF of Ni and, to a small degree, BCF of Cu in shoots of maize, compared to the control series. Compost, zeolite and especially bentonite are very good amendments in the restoration of maize growth in polluted areas.

“…Lead concentrations in roadside soils are typically 50 to 2000 mg kg −1 within a 30‐m distance of roads resulting from past use of leaded gasoline (Davidson and Rabinowitz, 1992). Elevated Cu concentrations up to >100 mg kg −1 have been reported in the vicinity of roads resulting from brake and tire wear (Marino et al, 1992; Dierkes and Geiger, 1999; Garcia et al, 1996; Oorts, 2010). Tire‐wear particles are also recognized as a source of Zn to the environment (Councell et al, 2004).…”

Source identification is an important step towards predictive models of urban heavy metal (HM) contamination. This study assesses the spatial distribution of enrichment of eight HMs (As, Cd, Cr, Cu, Hg, Ni, Pb and Zn) in the city of Ghent (156.18 km 2 ; Belgium). A database with HM concentrations measured in the topsoil at 2138 point observations was collected from the Public Waste Agency of Flanders. The degree of anthropogenic HM enrichment was quantified using an urban pollution index (PI). Enrichment of HMs showed high variations throughout the study area due to manifold anthropogenic sources. Topsoil in Ghent was especially enriched with Cu, Ni, Pb and Zn, with median PI's of 1.91, 1.74, 2.12 and 2.02 respectively. Contrastingly, As, Cd, Hg, Cr generally did not exceed expected background concentrations, with median PI values < 1. Stratification of the PI based on land use (agriculture, park and recreation, residential zones, harbor and industry) generally revealed high enrichment of Cu, Ni, Pb and Zn in residential areas linked to housing and traffic, but proved unsatisfactory to capture major trends in urban spatial HM distributions. Moreover, an important control of industrial and traffic emissions is suggested for Ni, Cu, Pb and Zn. Industrial non-airborne point source contaminations were mainly historical, rather than linked to current industrial activities. Results indicated that urban-rural gradients or current land use stratification approaches are inadequate to predict spatial HM distributions in cities with a long history of industrialization.
