“…Soil/water content (moisture) was measured after cultivation as the loss on drying at 105°C. Exchangeable cations (Ca 2+ , Mg 2+ , K + , Fe 3+ , Zn 2+ , Cd 2+ , Cu 2+ , Ni 2+ , Pb 2+ ) were extracted with ammonium acetate (0.5 M) and EDTA (0.02 M) at pH 7 (Cottenie et al 1979) and their concentrations were measured with inductively coupled plasma emission spectrometer (ICP-OES) (Varian Vista-MPX). Organic matter (OM) content was measured by loss on ignition at 500°C.…”

Urban soil contamination with trace metals is a major obstacle to the development of urban agriculture as crops grown in urban gardens are prone to accumulate trace metals up to toxic levels for human consumption. Phytoextraction is considered as a potentially cost-effective alternative to conventional methods such as excavation. Field trials of phytoextraction with Noccaea caerulescens were conducted on urban soils contaminated with Cd, Cu, Pb, and Zn (respectively around 2, 150-200, 400-500, and 400-700 μg g −1 of dry soil). Metallicolous (Ganges population) and non-metallicolous (NMET) populations were compared for biomass production and trace metal uptake. Moreover, we tested the effect of compost and fertilizer addition. Maximal biomass of 5 t ha −1 was obtained with NMET populations on some plots. Compared to Ganges-the high Cd-accumulating ecotype from South of France often used in phytoextraction trials-NMET populations have an advantage for biomass production and for Zn accumulation, with an average Zn uptake of 2.5 times higher. The addition of compost seems detrimental due to metal immobilization in the soil with little or no effect on plant growth.In addition to differences between populations, variations of growth and metal accumulation were mostly explained by soil Cd and Zn concentrations and texture. Our field trials confirm the potential of using N. caerulescens for both Cd and Zn remediation of moderately contaminated soils-with uptake values of up to 200 g Cd ha −1 and 47 kg Zn ha −1 -and show the interest of selecting the adequate population according to the targeted metal.

“…Single reagent extraction with 0.5 mol/L ammonium acetate, containing 0.02 mol/L EDTA at pH 4.65 is used for the determination of trace elements in soils (Cottenie et al, 1979;Cottenie and Verloo, 1984) and correlates well with plant concentrations (Kiekens et al, 1984). It could also be useful to identify mobile pollutant pools in sediments (Tack and Verloo, 1991).…”

The solid phase distribution of metals in a contaminated dredged sediment as affected by a single reagent extraction (0.5 mol/L NH 4 OAc + 0.02 mol/L EDTA) was studied. A sediment was dried and portions were heated at 250°C and 450°C. From each treatment, a portion was extracted with NH 4 OAc-EDTA. Both the extracted and the unextracted portions were then subjected to a sequential fractionation.NH 4 OAc-EDTA extraction decreased both the acid extractable and the reducible fractions. The oxidizable and residual fractions were not significantly affected. Larger portions of the acid extractable and reducible fractions were extracted with NH 4 OAc-EDTA when the sediment was previously heated at 250°C. After heating the sediment at 450°C the NH 4 OAc-EDTA-extractable portions decreased.Fractionation procedures can provide reliable information on the chemical associations of pollutants in sediments. To estimate short and medium term metal availability, single reagent leaching tests appear more appropriate.
