“…That suggests that the high pH and C provided by the organic amendments reduced Cu mobility in the mine soil. All soils had most of Cu in the F5 and F6, indicating that this metal can be strongly bound to organic matter and it can form both soluble and insoluble complexes with organic compounds ( Pérez-Esteban et al 2013). Moreover, the plants grown in the 20 % amended soils had the highest total Cu concentrations, and the higher amendment rate, the lower the total Cu concentration in plant tissues (Table 4).…”

“…The soil samples with both treatments (waste amendment and B. juncea) had generally equal or lower pseudototal concentrations of Cu, Ni, Pb and Zn than the soils only amended (Table 3), which indicates that the use of both wastes, biochar and mustard plants provided a little additional benefit for remediating a metal-polluted soil compared with only the incorporation of wastes. B. juncea plants are suitable for revegetating mine soils because they can tolerate high levels of metals, and previous studies have shown that these plants are useful for phytostabilisation purposes in soils polluted by metals ( Pérez-Esteban et al 2013). …”

Purpose Soil metal pollution is a widespread problem around the world and remediation of these soils is difficult. The objective of this study was to investigate the effect of two different strategies on the chemical fractions of metals in a soil of a depleted copper mine: (1) amending with a mixture of a technosol made of wastes and biochar and (2) amending combined with planting vegetation (Brassica juncea). Materials and methods A 3-month greenhouse experiment was carried out to evaluate the effects of organic amendments and vegetation on the metal fractionation of Cu, Ni, Pb and Zn in a mine soil of the depleted copper mine at Touro (Spain). We compared the influence of organic amendments alone (technosol + biochar) and combined with mustard plants (Brassica juncea L.). Results and discussionThe results showed that amending with a technosol made of wastes promoted plant growth (from 0.7 to 2.9 g of biomass produced) and reduced the CaCl 2 -extractable metal concentration in soil, reduced the mobility factor of Cu from 18.3 to 1.6, Ni from 47.5 to 2.3 and Pb from 17.9 to 2.1, and also reduced the concentration of metals in the mobile soil fractions. It was not possible to grow up Brassica juncea plants in the untreated settling pond soil due to the extremely degraded conditions of that soil. However, the application of the used technosol increased the Pb and Zn pseudototal concentrations in the amended soils. Conclusions We conclude that the combination of amending with wastes and planting B. juncea provides little additional benefit for remediating a metal-polluted soil compared with incorporation of wastes alone.

“…There are large-scale and diversified mineral sources in China, and proven reserves of mineral resources constitute 12 % of the total mineral resources in the world . Soils in these areas often show bad fertility conditions, limited vegetation, and intensive erosion by rain and wind (Pérez-Esteban et al 2014).…”

“…Compost produced from different green waste sources (plant leftovers, pine bark, etc.) has been used as a nutrient source and soil conditioner to improve plant growth (Farrell and Jones 2010;Pérez-Esteban et al 2014). However, studies about organic amendments not only focus on being a way to improve soil fertility but also are proposed for the remediation of heavy metal contaminated soils.…”

The application of organic amendments into heavy metal contaminated soil is considered as an environmentally friendly technique to promote the potential of phytoremediation. A pot experiment was carried out to evaluate the effect of humic substances on growth, cadmium (Cd) accumulation and phytostabilization potential of the mining ecotype (ME) and the corresponding non-mining ecotype (NME) of Athyrium wardii (Hook.) grown in Cd-contaminated soils. The addition of the humic substances demonstrated great promotion for the growth and Cd uptake of ME. Both plant biomass and Cd concentration significantly increased with the increasing application of the humic substances up to 100 g kg(-1), beyond which no significant change of underground part biomass and Cd concentrations in underground part of A. wardii was observed. The maximum Cd concentration in underground part of ME was 180 mg kg(-1) when 150 g kg(-1) humic substances were applied. The ME showed greater Cd accumulation capability in underground part (0.47-0.68 mg plant(-1)) than that of NME (0.27-0.45 mg plant(-1)). Increasing bioaccumulation coefficient (BCF) values of A. wardii was observed with increasing application of the humic substances. The BCF values of ME were higher than those of NME. However, the use of the humic substances exhibited little impact on translocation factors (TFs) of ME, and the TF values of ME were less than NME. Furthermore, the application of the humic substances improved the remediation factors (RFs) of A. wardii. The RF values in underground part of ME ranging from 0.73 to 0.91 % were apparently higher than those of NME. These results indicated that the humic substances can be a potential candidate for enhancing the phytostabilization of A. wardii grown in Cd-contaminated soils.

Phytostabilization has been proposed as a promising tool for long-term management of polluted sites. Optimization of the process efficiency involves choosing suitable amendments to allow both efficient plant growth and the immobilization of contaminants. The objectives of this study are to evaluate the effect of amendments on (i) the physicochemical properties of technosol and (ii) the mobility and phyto-availability of metal(loid)s. A dwarf bean growth test is conducted on technosols amended with compost, garden soil, slag, and biochar. The physicochemical properties of soil pore water (SPW) are determined as well as the phyto-available concentrations of metal(loid)s by simple extraction tests. All amendments used are able to increase SPW pH and electrical conductivity, allowing a decrease in the lead concentration in SPW by 90% and the lead phytoavailable part by 93%. However, for all amendments, SPW As concentration increased. Lastly, the amendments improve bean growth and tend to decrease the metal(oid) concentrations in aerial organs. As concentration in roots did not decrease whereas Pb concentration decreased. Metal(loid) concentrations of Pb accumulated in the aerial parts of beans and their extractable concentrations show a significant positive correlation with the extraction procedures. In contrast, the phytoavailable As shows a weak correlation with As concentrations in the aerial parts. The 1-M NH 4 NO 3 extraction procedure is the most appropriate and provides the most useful indications of the phytoavailability for the studied elements.
