“…The BIO-1 and BCW-1 treatments were the most effective while FYM-1 failed to significantly (p < 0.05) immobilise Zn. In comparison, a 4-week pot incubation study involving FYM amendment (1, 2 and 3% w/w) of an alluvial clay soil led to reduced Zn bioavailability (up to 26%) in the 2% treatment through precipitation with phosphates and carbonates released from OM decomposition (Sabir et al 2014). On the other hand, Uzinger et al (2014) found that Zn sorption increased at higher BCW rates (0-10% w/w) in an acidic soil with a range of low and high concentrations (0-1500 mg kg −1 Zn).…”

Organic sorbents alter physicochemical soil properties and mitigate heavy metal (HM) bioavailability. However, some sorbents are labile and, therefore, introduce the risk of HM release into soil after mineralisation. Before field application, new stable organic sorbents such as woodchip biochar (BIO) and brown coal waste (BCW) need to be tested and compared with standard organic amendments like farmyard manure (FYM). An incubated pot experiment was conducted to investigate the efficacy of FYM, BIO and BCW (added to soil in pots at 5 and 10% w/w) to alter soil physicochemical properties and mitigate bioavailability of Cd, Pb and Zn spiked in treatments at different doses (in mg kg−1); 0 (not spiked), 1 (1 Cd, 70 Pb, 100 Zn) and 2 (3 Cd, 500 Pb, 700 Zn), and incubated for 9 weeks. At the end of the experiment, the EDTA-extractable HM fractions, pH, cation exchange capacity (CEC) and specific surface area (SSA, to check trends) were determined in all treated soils. Results showed that FYM, BCW and BIO generally improved all soil properties (except reduced pH from BCW and apparent SSA reduction from FYM) and accounted for respective maximum abatements of Cd (50.2, 69.9 and 25.5%), Pb (34.2, 64.3 and 17.4%) and Zn (14.9, 17.7 and 11.8%) bioavailability in soil. FYM and BCW were more effective at 10% w/w especially in the low contaminated soil, whereas the highest efficacy for BIO was at 5% w/w and in the high contaminated soil. The efficacies of sorption by the organic sorbents varied for different HMs and were in the orders: BCW > FYM > BIO for Cd, FYM > BCW > BIO for Pb and BIO > BCW > FYM for Zn. Soil pH and CEC were strongly correlated with HM bioavailability in all treatments and implied that immobilisation of HMs occurred via complex formation, ion exchange and pH-dependent specific adsorption. All three sorbents were beneficial as soil amendments, and in terms of HM mitigation, BCW had the highest efficacy, followed by FYM and then BIO. Considering the documented high soil stability of BCW and BIO, these results are promising for further trialling at field scale.

“…Higher RF indicates extraction efficiency of the metals from the soil due to increased solubilization of metals in the soil and vice versa (SABIR et al, 2015). Mean RF for Pb with MSCW was higher compared to the RF with NS500, suggesting that Pb was extracted more efficiently by the plants grown with MSCW (Table 7).…”

“…Thus, a higher CEC of the soil leads to the greater the sorption and immobilization of the metals (GUPTA et al, 2013). In addition, the addition of MSWC enhanced OM, which could bind Pb and Zn thus decreasing their solubility in the soil (SABIR et al, 2015). In the other words, an increase in the concentration of compost results in a subsequent decrease in heavy metal solubility.…”

This study was conducted to evaluate Pb and Zn uptake, mobility, and accumulation in Stipa hohenackeriana using field soil in pot and field experiments. Moreover, the effects of Municipal Solid Waste Compost (MSWC) (0, 1, and 2%) and Nano-Silica (NS) (0, 250, and 500 mg/kg) on Stipa biomass, Pb and Zn availability in the soil, and Pb and Zn uptake and accumulation were studied using pot experiments. Samples of soil, root, and shoots of Stipa were collected from field and greenhouse and after drying, extraction of Pb and Zn was done by acid digestion. BioConcentration Factor (BCF) and Translocation Factor (TF) were calculated to determine Pb and Zn phytoremediation efficiency. The amount of Zn and Pb remediation by Stipa from soil was determined by remediation factor (RF). The results of field experiments showed the Pb and Zn level decreased in the order of: soil >shoot>root. Results of the pot experiments also showed that plants grown in NS500-amended pots had 33% and 32% higher Pb in roots and shoots compared to control pots, respectively. In comparison, roots Pb concentration in pots amended with MSWC1% and MSWC2% decreased 22.4% and 1.7%, respectively. Roots and shoots Zn concentration in NS500-amended pots was 5.6% and 6.5% higher, respectively. However, root Zn concentration in treatments of MSWC1% and MSWC2% decreased 52.3% and 39.4%, respectively. Shoots Zn concentration decreased 52.5% and 40.0%, respectively. Although MSWC decreased the uptake and accumulation of Pb and Zn in Stipa roots and shoots, it improved the plant growth and consequently increased RF and soil remediation compared to the NS. Thus, it seems that applying MSWC and NS simultaneously can be a suitable strategy for the purpose of improving phytoremediation capability of Stipa in the Pb and Zn contaminated soils. In general, Stipa can be a suitable candidate for the accumulation of heavy metals, especially for Pb and Zn contaminated soils.

“…In the second experiment, the relatively high germination in treatments with 5% OM and lime: could have been associated with soil pH increase, better structure and nutrients provided by lime and OM. In addition OM could have reduced the availability of metals by changing these from bioavailable forms to less-available forms in the fractions associated with organic matter, metal oxides, or carbonates [16], [17] 3.3 Greenhouse Study-Plant Biomass Production Biomass production in the first experiment varied widely depending on treatment. As expected, the uncontaminated soil (positive control) had the highest biomass.…”

The landscape legacy of historical metal-mining activity can persist for decades. The most frequent strategies used for the remediation of contaminated soils include: the use of synthetic membranes to isolate contaminants, direct revegetation, or lime amendments. Looking for more cost-effective bioremediation approaches, we performed a set of greenhouse studies to determine what combinations of soil amendments would lead to the best vegetative response, and potentially associated reductions in soil arsenic (As) levels. In our first greenhouse experiment, we planted Leymus cinereus (basin wildrye) in tailings, compared (after 12 weeks) plant growth, and foliar metal concentrations across treatments. Amendments included single or factorial additions of lime, 5% organic matter (+OM), and an arsenic-oxidizing (+oxbact) strain of Agrobacterium tumefaciens (Agtu). For the first experiment, only one level of OM amendment was tested (5%) and a second greenhouse experiment with two levels of OM (1.5% and 5%). In this second experiment, Basin wildrye grown in soils amended with 5% OM generally did better than those grown in soils amended with 1.5% OM and even better in soils amendment with 5% OM + oxbact. These results suggest the combination of OM and Agtu oxbact strain could provide a potentially cost-effective approach to remediating As-contaminated soils.
