“…Phytoextraction with hyperaccumulating plants has been suggested to be a promising technique to remediate soils contaminated with trace metals (Hammer and Keller 2003;Koopmans et al 2008;Maxted et al 2007;McGrath et al 2006;Robinson et al 1998;Schwartz et al 2003;Zhao et al 2003). Hyperaccumulating plants accumulate metals in shoots at concentrations above defined thresholds when grown in their natural habitats, i.e., 100 μg g −1 for Cd, 1000 μg g −1 for Ni, or 3000 μg g −1 for Zn, on a dry weight basis (Krämer 2010;van der Ent et al 2013).…”

“…caerulescens (Brassicaceae, formerly Thlaspi caerulescens) is one of the most promising candidate species for Cd and Zn phytoextraction (Koopmans et al 2008;Maxted et al 2007;McGrath et al 2006;Zhao et al 2003). Three ecotypes of N. caerulescens have been described: metallicolous plants grow in soils enriched in Cd-Zn-Pb (calamine, CAL) and in serpentine sites (mostly enriched in Ni), whereas non-metallicolous (NMET) grow in uncontaminated soils (Escarré et al 2000;Meerts and van Isacker 1997;Molitor et al 2005;Reeves et al 2001).…”

“…Despite the need of field experiments on a range of soil conditions to assess the actual phytoextraction efficiency, the number of field trials reported in the literature is surprisingly still very scarce (Hammer and Keller 2003;Maxted et al 2007;McGrath et al 2006;Schwartz et al 2003;Simmons et al 2015;Tlustoš et al 2016), in comparison to pot experiments (see 14 references in Li et al 2012). So far, the limits of the method and the biggest lack of knowledge that still need to be field tested concern the adequate agricultural practices, e.g., fertilization, weed and pest control, irrigation and resistance to hot weather, and optimal length of growth (Koopmans et al 2008;Li et al 2012;Maxted et al 2007;McGrath et al 2006;Vangronsveld et al 2009). …”

“…It would however be relevant to confirm this by performing a field trial in a growth cycle following the dominant natural cycle of the plant (germination in autumn, vernalization, flowering and harvest in late spring/ early summer). In sum, while most studies focus on the use of CAL populations (Koopmans et al 2008;Maxted et al 2007;McGrath et al 2006), the relative advantage of NMET populations for biomass production and resistance to herbivory should be taken into account and further studied.…”

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.

“…The reactive fraction represents sorbed metals reacting with binding sites located on surfaces of soil organic matter (SOM), amorphous metal oxides, and clay and is believed to control the metal concentration in the soil solution (Weng et al 2001;Tipping et al 2003). Adsorption-desorption equilibria between the reactive metal pool in the soil-solid phase and the metal concentration in soil solution have been described with empirical solid-solution partitioning models in which pH and cation exchange capacity (CEC) were included to account for differences between soils (Römkens et al 2004;Ingwersen and Streck 2006;Meers et al 2007;Koopmans et al 2008a). Various extracts are used to determine the size of the reactive metal pools including dilute acids like 0.43 M HNO 3 (Houba et al 1997;Weng et al 2001;Tipping et al 2003), 0.1 M HCl (Colombo and van den Berg 1998), and EDTA (Clayton and Tiller 1979).…”

Characterization of soil heavy metal pools in paddy fields in Taiwan: chemical extraction and solid-solution partitioning

et al. 2009

Background, aim, and scope Ongoing industrialization has resulted in an accumulation of metals like Cd, Cu, Cr, Ni, Zn, and Pb in paddy fields across Southeast Asia. Risks of metals in soils depend on soil properties and the availability of metals in soil. At present, however, limited information is available on how to measure or predict the directly available fraction of metals in paddy soils. Here, the distribution of Cd, Cu, Cr, Ni, Zn, and Pb in 19 paddy fields among the total, reactive, and directly available pools was measured using recently developed concepts for aerated soils. Solid-solution partitioning models have been derived to predict the directly available metal pool. Such models are proven to be useful for risk assessment and to derive soil quality standards for aerated soils. , and directly available metal pools (0.01 M CaCl 2 ) were determined. Solid-solution partitioning models were derived by multiple linear regressions using an extended Freundlich equation using the reactive metal pool, pH, and the cation exchange capacity (CEC). The influence of Zn on metal partitioning and differences between both sampling events (May/November) were evaluated. Results Total metals contents range from background levels to levels in excess of current soil quality standards for arable land. Between 3% (Cr) and 30% (Cd) of all samples exceed present soil quality standards based on extraction with AR. Total metal levels decreased with an increasing distance from the irrigation water inlet. The reactive metal pool relative to the total metal content is increased in the order Cr << Ni = Zn < Pb < Cu < Cd and ranged from less than 10% for Cr to more than 70% for Cd. Despite frequent redox cycles, Cd, Pb, and Cu appear to remain rather reactive. The methods to determine the reactive metal pool in soils yield comparable results, although the 0.43 M HNO 3 extraction is slightly stronger than HCl and EDTA. The close correlation between these methods suggests that they release similar fractions from soils, probably those reversibly sorbed to soil organic matter (SOM) and clay. The average directly available pool ranged from less than 1% for Cu, Pb, and Cr to 10% for Ni, Zn, and Cd when compared to the reactive metal pool. For Cd, Ni, Zn, and to a lesser extent for Cu and Pb, solid-solution partitioning models were able to explain up to 93% (Cd) of the observed variation in the directly available metal pool. CaCl 2 extractable Zn increased the directly available pool for Ni, Cd, and Cu but not that of Pb and Cr. In the polluted soils, the directly available pool was higher in November compared to that in May. Differences in temperature, rainfall, and changes in soil properties such as pH are likely to contribute to the differences observed within the year. The solid-solution partitioning model failed to explain the variation in the directly available Cr pool, probably because Cr is present in precipitates rather than being adsorbed onto SOM and clay. Despite obvious differences in parent material, source of pollu...
