“…The data in Table 4 also show that the content of Pb in grains of rice (O. sativa) was 14-fold higher than the maximum permitted level (0.2 mg/kg) for food and feed [100,101]. Accumulation of Pb in rice to levels higher than 0.2 mg/kg has been reported [102,103], indicating that the uptake of Pb by roots and its accumulation in rice present a considerable risk. The contents of As and Pb in spinach (I. aquatica) were approximately 3-and 293-fold higher, respectively, than the standard allowance for vegetables [101] (1.0 and 2.0 mg/kg-DW, respectively).…”

This study was conducted to determine the soil contamination and the accumulation of arsenic (As) and heavy metals including chromium (Cr), copper (Cu), zinc (Zn), cadmium (Cd), and lead (Pb) in 15 native and cultivated plant species in a Pb recycling area of Dong Mai village, Hung Yen Province, Vietnam. The analysis of 32 soil samples collected from seven different sites in the study area revealed that the contents of Al, Fe, As, Cr, Cu, Zn, Cd, and Pb in the soils ranged from 6200–32,600, 11,300–55,500, 5.4–26.8, 24.9–290, 66.0–252, 143–455, 0.71–1.67, and 370–47,400 mg/kg, respectively. The contents of As, Cr, Cu, Zn, Cd, and Pb in rice grains and the shoots of 15 plant species ranged from 0.14–10.2, 1.00–10.2, 5.19–23.8, 34.7–165, 0.06–0.99, and 2.83–1160 mg/kg-dry weight (DW), respectively. Hymenachne acutigluma (Steud.) Gilliland, a potential hyperaccumulator of Pb (1160 mg/kg–DW), is considered the best candidate for phytoremediation of Pb-contaminated soil. The cultivation of rice and vegetables, and the use of some native plants for food for humans, pigs, and cattle should be managed with consideration of the accumulation of Pb in their aboveground biomass.

“…For Cd and Pb soil concentrations, a significantly higher reduction efficiency than the control was observed with the SM + L and SM + FeO treatments, with reduction efficiencies of 64.6% and 55.4% for As, respectively, and 41.4% and 35.5% for Pb, respectively. Various researchers have pointed out that soil pH is a major factor influencing the decrease in the bioavailable fraction of the cationic form of heavy metals in soil [1,[34][35][36]. In our study, soil pH was significantly increased when SM was combined with lime, compared to the control (Table 3).…”

Heavy metal pollution and greenhouse gas (GHG) emissions from soil are two major detrimental sources in the agriculture environment because of concerns about crop safety and global warming. Applying amendments on site is a common technique used for heavy metal remediation and the reduction in GHG emissions. This study aims to evaluate the effect of different amendments on the reduction in both bioavailable heavy metals and GHG emissions from soil. Four different amendments, namely bottom ash (BA), sintered material (SM), sintered material combined with lime (SM + L), and FeO (SM + FeO) were applied to upland fields, followed by maize (Zea mays L.) cultivation from April to October. Subsequently, SM + FeO treatment demonstrated the highest bioavailability reduction efficiency for As at 79.1%, and SM + L treatment had a high efficiency for the reduction in Cd and Pb by 64.6% and 41.4%, respectively. SM + FeO treatment also reduced bioaccumulated As and Pb in maize grain by 59.3% and 66.2%, respectively. Furthermore, SM + FeO treatment demonstrated the highest reduction efficiency for cumulative N2O emissions by 70.7%, compared to the control soil. Among the four different amendments, the efficiency of heavy metal and GHG emission reduction was in the following order: SM + FeO > SM + L > SM > BA. Overall, SM combined with FeO is a promising amendment for reducing and managing both heavy metal pollution and GHG emissions in soil.

“…The accumulation of Zn in the roots and shoots of Canavalia ensiformis and Mucuna aterima was reduced by more than 50% and 30%, respectively. At the same biochar application rate, very similar reductions were achieved on Dactylis glomerata L., Brassica chinensis L., Oryza sativa L., Salix viminalis L., Lolium perenne L. and Lolium multiflorum L., leading to improved growth of the species on either acidic or alkaline soils [ 57 , 186 , 187 , 188 , 189 , 190 ]. By applying olive tree prunings biochar to a mining soil at a rate of 10%, Beesley et al (2014) confirmed his earlier findings regarding Zn.…”

Soil contamination with potentially toxic elements (PTEs) is considered one of the most severe environmental threats, while among remediation strategies, research on the application of soil amendments has received important consideration. This review highlights the effects of biochar application on soil properties and the bioavailability of potentially toxic elements describing research areas of intense current and emerging activity. Using a visual scientometric analysis, our study shows that between 2019 and 2020, research sub-fields like earthworm activities and responses, greenhouse gass emissions, and low molecular weight organic acids have gained most of the attention when biochar was investigated for soil remediation purposes. Moreover, biomasses like rice straw, sewage sludge, and sawdust were found to be the most commonly used feedstocks for biochar production. The effect of biochar on soil chemistry and different mechanisms responsible for PTEs’ immobilization with biochar, are also briefly reported. Special attention is also given to specific PTEs most commonly found at contaminated soils, including Cu, Zn, Ni, Cr, Pb, Cd, and As, and therefore are more extensively revised in this paper. This review also addresses some of the issues in developing innovative methodologies for engineered biochars, introduced alongside some suggestions which intend to form a more focused soil remediation strategy.
