“…The HM contents in maize straw, grain, and leaf were mostly ampli ed with increasing OA application, which was consistent with the results of previous studies (Bose & Bhattacharyya, 2008;Eid et al, 2019b;Taghipour & Jalali, 2019) that had demonstrated that OA application increased the uptake of HMs in wheat (Eid et al, 2019a), spinach (Eid et al, 2017), and sugarcane (Nogueira et al, 2013). The HM concentrations in aboveground parts of maize were lower than the threshold of the national standards for food safety, although Cd contents in the grain and leaf of maize surpassed the threshold (GB2762-1017) at the 150 and 300 t ha -1 SS application rate.…”

Organic amendments (OAs) can be a sustainable and effective method for mudflat soil improvement. A long-term field experiment was conducted to investigate the potential of OA application to mudflat soil improvement. We measured the pH, soil organic matter (SOM), salinity, maize growth, and heavy metal (HM) accumulation in OA-amended soils and maize tissues 23 months after three OAs, sewage sludge (SS), Chinese medical residue (CMR), and cattle manure (CM), were applied at the application rates of 0, 30, 75, 150, and 300 t ha-1. OA application significantly increased the SOM and decreased the salinity of mudflat soils. Additionally, CMR and CM application decreased soil pH. The maize biomass and HM contents in soil and maize increased after OA application. The bioavailability and bioconcentration of HMs were generally in the sequence of SS>CMR>CM. The average bioavailability ratios of HMs were in the order of Cd>Zn>Cu>Mn>Ni. The bioconcentration of Zn and Cd by maize was highest, followed by Mn, Cu, and Ni. SOM, pH, and salinity were the important factors regulating soil available HMs and, subsequently, HM accumulation in maize. Among the three OAs, SS is most effective in decreasing soil salinity and increasing the SOM, bioavailability and bioconcentration of HMs. On the other hand, CM was the best OA because it promoted significant maize growth yet maintained low HM contamination risk.

“…Limit of detection (LOD) is defined as the minimum concentration of a substance that can be measured and it is the ratio of the value of three times the standard deviation of the blank sample to the slope of the calibration curve. Three replicate blank samples were digested following the same procedures utilized for digesting the spice samples [ 14 , 15 ].…”

A total of 144 spice samples (ajwain, black cumin, coriander and fenugreek) were collected from three districts. For the determination of heavy metals (Cd, Cr, Cu, Pb and Zn) concentrations and human health risks, the spice samples were digested in a mixture of HNO 3 and HClO 4 . The highest concentrations of Cr (24.85 AE 1.673 mg/kg) and Cu (32.267 AE 7.355 mg/kg) were investigated in ajwain and Zn (54.13 AE 6.122 mg/kg) in fenugreek. However, lowest concentration of Cr and Cu were detected in fenugreek; and Zn in coriander. Cd and Pb were not detected in all spice samples. A positive correlation was observed among Cr, Cu and Zn in fenugreek; Zn with Cr and Cu in black cumin and Zn with Cu in ajwain and coriander. However, negative correlation was observed Cr with Cu and Zn in ajwain and coriander; Cr with Cu in black cumin. THQ values of Cu, Zn and 75% of Cr in all spices were less than 1. About 66.7% of the HI values of the samples under study were less than 1, indicated that the consumers will not experience potential health risks from the intake of individual metals through spices consumption.

“…In other studies, mineral-based amendments such as zeolite, CaO, bentonite, and dolomite effectively immobilized PTE in soil and increased the yields of the tested plants [37]. The mechanism by which plant roots absorb PTE is highly complex and involves several processes, including cation exchange across cell walls, intracellular transport and rhizosphere processes [38,39]. Plant cover can limit the migration of PTE to deeper soil horizons and above-ground plant parts by stabilizing pollutants in the rhizosphere [40].…”

Immobilization of Potentially Toxic Elements (PTE) by Mineral-Based Amendments: Remediation of Contaminated Soils in Post-Industrial Sites

et al. 2020

In many post-industrial sites, the high contents and high mobility of different potentially toxic elements (PTEs) make the soils unsuitable for effective management and use. Therefore, immobilization of PTE seems to be the best remediation option for such areas. In the present study, soil samples were collected in post-industrial areas in Northeastern Poland. The analyzed soil was characterized by especially high contents of Cd (22 mg·kg−1), Pb (13 540 mg·kg−1), and Zn (8433 mg·kg−1). Yellow lupine (Lupinus luteus L.) and two types of mineral-based amendments were used to determine their combined remediation effect on PTE immobilization. A greenhouse pot experiment was conducted to evaluate the influence of chalcedonite and halloysite on plant growth, chlorophyll a fluorescence, the leaf greenness index (SPAD), PTE uptake, and the physicochemical properties and toxicity of soil. The application of chalcedonite resulted in the greatest increase in soil pH, whereas halloysite contributed to the greatest reduction in the contents of Ni, Pb, Zn, and Cr in soil, compared with the control treatment. The addition of halloysite significantly increased plant biomass. The application of mineral-based amendments increased the ratio of variable fluorescence to maximum chlorophyll fluorescence (Fv/Fm) in yellow lupine leaves. The leaf greenness index was highest in plants growing in soil amended with chalcedonite. The results of this study suggest that mineral-based amendments combined with yellow lupine could potentially be used for aided phytostabilization of multi-PTE contaminated soil in a post-industrial area.
