“…Chloride enhances Cd mobility and bioavailability in soil solution by forming relatively stable and phyto-available complexes of CdCl n 2−n (Filipović, Romić et al 2018, Raiesi and Sadeghi 2019, Guo, Chen et al 2022. The EC values of biochars produced in this study ranged from 0.81 (RH300) to 6.38 (SBP600).…”

This study addressed the bioaccumulation and human health risk among consumption of Spinacia oleracea grown in agricultural soil treated with humic acid and biochars. The biochars came from two local feedstocks of rice husk (RH) and sugar beet pulp (SBP) pyrolyzed at temperatures 300 and 600°C. The effect of soil treatment with biomass/biochar and humic acid in the accumulation of Heavy metals (HMs) in spinach leaves was considered under the controlled laboratory conditions. Optimum conditions for minimum accumulation of HMs were evaluated according to a central composite design (CCD) under the response surface method (RSM) by Design Expert software. Total concentrations of Cu, Cd, and Ni in soil and biomass/biochar were beyond acceptable standards worldwide. The concentrations of Zn, Cd, Pb, and Ni in spinach exceeded the safety threshold limit, and its consumption is not recommended. Results of the desirability test suggested the minimum values of biomass/biochar application rate due to their metal-contaminated nature. The minimum concentration of humic acid also was suggested due to its role in promoting pollutant bioavailability. Results showed that the treatment of metal-contaminated soil with HMs polluted-biochars fails to stabilize pollution. Also, polluted biochars increased the hazard indices for non-carcinogenic and carcinogenic diseases beyond the permissible levels.

“…More importantly, the isotope depletion between the rice plant and soil solution is also erased after the addition of chloride and sulfate ions due to the effect of Fe plaque, but the uptake of Cd into rice plants was facilitated because of the uptake of inorgano-Cd complexes, the increased soil Cd solubility, or efficient uptake systems. Chloride weakens Cd immobilization in soils, even when lime and biochar are applied. , Considering the application of inorganic fertilizers (e.g., KCl) and seawater intrusion, Cd transport can be facilitated in soil–rice systems. Regarding the sulfate ion, the application of exogenous SO 4 2– (<100 mg S kg –1 soil) could decrease the Cd solubility and grains by precipitating as CdS. , However, the results of this and previous studies show that SO 4 2– promotes Cd accumulation in rice seeds (exogenous SO 4 2– exceeding 200 mg S kg –1 soil). , Therefore, the excessive use of potassium sulfate in Cd-contaminated paddy fields promotes Cd transport from soils to grains, which is undesirable for substituting potassium chloride from the perspective of the toxic side of Cd.…”

Anions accompanying inorganic fertilizers, such as chloride and sulfate ions, potentially affect the solubility, uptake, and transport of Cd to rice grains. However, the role of anions in controlling Cd transport in the soil−soil solution−Fe plaque−rice plant continuum remains poorly understood. Cd isotope ratios were applied to Cd-contaminated soil pots, hydroponic rice, and adsorption experiments with or without KCl and K 2 SO 4 treatments to decipher transport processes in the complex soil−rice system. The chloride and sulfate ions increased the Cd concentrations in the soil solution, Fe plaque, and rice plants. Accordingly, the magnitude of positive fractionation from soil to the soil solution was less pronounced, but that between soil and Fe plaque or rice plant is barely varied. The similar isotope composition of Fe plaque and soil, and the similar fractionation magnitude between Fe plaque and the solution and between goethite and the solution, suggested that desorption-sorption between iron oxides and the solution could be important at the soil−soil solution−Fe plaque continuum. This study reveals the roles of chloride and sulfate ions: (i) induce the mobility of light Cd isotopes from soil to the soil solution, (ii) chloro-Cd and sulfato-Cd complexes contribute to Cd immobilization in the Fe plaque and uptake into roots, and (iii) facilitate second leaves/node II-to-grain Cd transport within shoots. These results provide insights into the anion-induced Cd isotope effect in the soil−rice system and the roles of anions in facilitating Cd migration and transformation.

“…Since genotoxicity is the prerequisite for the incidence of most malignancies, a series of heavy metals have been classified as Group I carcinogenic agents by the International Agency for Rese [ 15 ]. Itai-itai disease, Minamata disease and cadmium-polluted rice caused by heavy metal contaminations have all seriously threatened human health throughout history [ 16 , 17 ].…”

Widespread heavy metal pollution has aroused severe health risks worldwide. Curcumin has been reported to play a wide-spectrum protective role for various heavy metals. However, the specificity and difference in the antagonistic ability of curcumin against distinct types of heavy metals are still largely unknown. Here, using cadmium (Cd), arsenic (As), lead (Pb), and nickel (Ni) as the typical heavy metals, we systematically compared the detoxification efficiency of curcumin on the cytotoxicity and genotoxicity elicited by different heavy metals under the same experimental conditions. Curcumin was proved to have a significant discrepant antagonistic capacity when counteracting the adverse effect of different heavy metals. Stronger protective effects of curcumin emerged when antagonizing the toxicity of Cd and As, rather than Pb and Ni. Curcumin exhibits a better detoxification ability against heavy metal-induced genotoxicity than cytotoxicity. Mechanistically, inhibiting the oxidative stress elicited by heavy metals and reducing the bioaccumulation of metal ions both contributed to the detoxification of curcumin against all the tested heavy metals. Our results illustrated that curcumin shows prominent detoxification specificity against different types of heavy metals and toxic endpoints, which provides a new clue for the better and targeted application of curcumin in heavy metal detoxification.
