“…Chelating agents induce the release of Cd from the soil solid phase into the soil solution and increase the DTPA-Cd content that, in turn, increases its enrichment and accumulation by plants and decreases soil total content of Cd (Beygi and Jalali, 2019;Chen et al, 2019;Gul et al, 2019). As appeared from Fig.…”

The present study, via a 180-days field trial, investigated the potential of chelate tetrasodium glutamate diacetate (GLDA) for the remediation of cadmium (Cd)-contaminated farmlands by French marigold. To do so, five GLDA treatments (e.g., 0, 292.5, 585, 1170, and 2340 kg hm− 2) were practiced. For each treatment, the total GLDA was divided into two applications with 15 day intervals (0.25, 0.47, and 0.61 mg·kg− 1) under French marigold plantation. Compared with the control, our results showed that GLDA application significantly increased the biomass of aerial parts of French marigold by 21.9% (p < 0.05). Likewise, Cd content in aboveground and underground parts of French marigold increased by 94.7% and 60.5%, respectively, compared with the control (p < 0.05). GLDA application caused significant increases in Cd accumulations in cell soluble fraction and cell wall by 290% and 123%, respectively (p < 0.05); Soil pH and DTPA-Cd content increased with the increase of total application of GLDA. Co-application of GLDA (2340 kg hm− 2) and French marigold reduced the total soil Cd content by 12.87% compared with the soil background. Altogether, our findings conclude on the efficacy of GLDA application for the remediation of Cd contaminated farmlands under French marigold cultivation.

“…Furthermore, the field-scale TM assessment model improves the monitoring of TM stress from its predecessor, the generalized dynamic fuzzy neural network model [ 88 ]. Compared with traditional methods (toxicity characteristic leaching, diethylenetriaminepentaacetic acid extraction, and HCl extraction), field capacity-derived soil solution extraction can successfully predict the total Cd content of rice from the tillering to mature stages [ 89 ]. The development of science and technology has permitted the gradual application of remote sensing technology to the TM monitoring of crops, for example, the collection of biochemical and hyperspectral data.…”

The threat of toxic metals to food security and human health has become a high-priority issue in recent decades. As the world’s main food crop source, the safe cultivation of rice has been the focus of much research, particularly the restoration of toxic metals in paddy fields. Therefore, in this paper, we focus on the effects of toxic metals on rice, as well as the removal or repair methods of toxic metals in paddy fields. We also provide a detailed discussion of the sources and monitoring methods of toxic metals pollution, the current toxic metal removal, and remediation methods in paddy fields. Finally, several important research issues related to toxic metals in paddy field systems are proposed for future work. The review has an important guiding role for the future of heavy metal remediation in paddy fields, safe production of rice, green ecological fish culture, and human food security and health.

“…Anthropogenic activities such as mining, smelting, phosphate fertilizers, contaminated manures including biosolids, industrial effluents, waste discharges, and raw sewage water for irrigation activities are the major sources of Cd buildup in soils (Ahmed et al, 2021;NaziaTahir et al, 2021). The toxic concentration of Cd deteriorates the soil productivity leading to diminishing availability of arable lands, interfering with the normal functioning of plants which is expressed as decreased growth rate and disturbed metabolic activity, and becoming a risk to human health (Azhar et al, 2019;Chen et al, 2019), causing cancer and serious cardiovascular disorders (Ebrahimi et al, 2020;NaziaTahir et al, 2021). The Cd is found in both free and complex forms in soil, and the chemical speciation and varying distribution of Cd (adsorbed or free) in soil determine its phytoavailability (Ondrasek et al, 2020;Riaz et al, 2021).…”

Phytoavailable cadmium (Cd) refers to the fraction of total cadmium in soil that is easily taken up by plants, which degrades the environmental quality and can cause contamination in the food chain. Cd contamination causes high carcinogenicity and toxicities, which harm both the environment and human health, including damage to the kidneys, bones, and respiratory system. In this study, seven extracting agents like ammonium bicarbonate diethylene triamine penta acetic acid (ABDTPA) and neutral salts having low and higher concentrations were used for the determination of phytoavailable Cd in sandy clay loam (SCL) and clay loam (CL) soils contaminated with Cd at naturally-Cd, Cd-20, Cd-40, and Cd-60 mg kg-1 and correlate it with Cd contents in roots, shoots, and grains of maize crop. Extraction efficiency of extractants remains in order: 10 M NH4AOc > ABDTPA > 1 M NH4AOc > 0.1 M CaCl2 > 0.01 M CaCl2 > 1 M NaNO3 > 0.1 M NaNO3. ABDTPA showed significantly the highest positive correlation with maize roots, shoots, and grains Cd contents in naturally Cd contaminated SCL and CL soils. While for artificially contaminated SCL and CL soils contaminated with Cd at Cd-20, Cd-40, and Cd-60 contamination levels, 0.1 M CaCl2 extractable Cd showed a stronger positive significant correlation with Cd contents in roots, shoots, and grains of maize crop. Overall results concluded that 10 M NH4AOc has the highest efficiency to extract Cd and 0.1 M NaNO3 has the lowest Cd extraction efficiency. Correlation results showed that ABDTPA and 0.1 M CaCl2 were found to be the most suitable extractants for predicting the bioavailability of Cd. Highly concentrated extractants give a stronger positive correlation as compared to low concentrated extractants. SCL soil showed stronger positive correlations as compared to CL soil
