The average concentrations (mg kg−1) of toxic trace elements were as follows: As: 0.17, Cr: 0.18, Ni: 0.55 and Pb: 0.18, while 7% and 40% of the rice samples surpassed, respectively, the EU recommended limits of As and Pb. This study revealed that rice could be a primary exposure pathway of toxic elements, leading to either noncarcinogenic or carcinogenic health problems for daily rice consumers. The non-carcinogenic health risk was mainly associated with As which contributed 77% to the hazard index. The carcinogenic risk measured as incremental lifetime cancer risk (ILCR) was high (>10−4) with As, Cr and Ni, while Pb showed a moderate (<10−4) carcinogenic risk to adults. Rice can substantially be contaminated by trace elements other than As with potential human health risks. Consequently, regular monitoring of the marketed rice grain is demanded, backed up by viable mitigation strategies for reducing toxic elements uptake by rice grains.]]> Wed 28 Feb 2024 15:54:22 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:42991 100 countries, and their distribution is extensive and widespread in arid and semi-arid regions of the world. In order to meet the challenges of global food security, it is imperative to bring barren salt-affected soils under cultivation. Various inorganic and organic amendments are used to reclaim the salt-affected lands. The selection of a sustainable ameliorant is largely determined by the site-specific geographical and soil physicochemical parameters. Recently, biochar (solid carbonaceous residue, produced under oxygen-free or oxygen-limited conditions at temperatures ranging from 300 to 1000 ^OC) has attracted considerable attention as a soil amendment. An emerging pool of knowledge shows that biochar addition is effective in improving physical, chemical and biological properties of salt-affected soils. However, some studies have also found an increase in soil salinity and sodicity with biochar application at high rates. Further, the high cost associated with production of biochar and high application rates remains a significant challenge to its widespread use in areas affected by salinity and sodicity. Moreover, there is relatively limited information on the long-term behavior of salt-affected soils subjected to biochar applications. The main objective of the present paper was to review, analyze and discuss the recent studies investigating a role of biochar in improving soil properties and plant growth in salt-affected soils. This review emphasizes that using biochar as an organic amendment for sustainable and profitable use of salt-affected soils would not be practicable as long as low-cost methods for the production of biochar are not devised.]]> Wed 28 Feb 2024 15:22:05 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:42992 Wed 28 Feb 2024 15:21:39 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:41745 Wed 28 Feb 2024 14:56:53 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:42905 Wed 28 Feb 2024 14:51:26 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:43947 Wed 28 Feb 2024 14:45:19 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:52052 Wed 27 Sep 2023 15:30:20 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:52053 Wed 27 Sep 2023 15:29:26 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:54991 Wed 27 Mar 2024 16:32:43 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:45366 Cu (∼95.01 to 90.53%) > Cd (∼92.5 to 55.25%) > Ni (∼80.85 to 50.6%), even in the presence of 0.01/0.001 M of CaCl2 and Na2SO4 as background electrolytes and charged organic molecule under an environmentally relevant concentration (200 μg/L).

The reduction of surface area, pore volume, and pore area of HNT-BC@Alg (after sorption of heavy metals) confirms that mesoporous surface (2–18 nm) supports diffusion, infiltration, and interaction. However, a lower range of mesoporous diameter of the adsorbent is more suitable for the adsorption of heavy-metal ions.

Increasing the incubation period and heat treatment resulted in a decrease of Be desorption and migration. The soil clay content and pH were the primary factors influencing Be desorption, and the results suggested that Be was desorbed from metal oxyhydroxides and surfaces of silicates (e.g., reactive surfaces of clay minerals), organic matters, and soil pores. Because of high Kd values, the mobility of Be was limited, and no exceedances of ecological or human health risk index or guidelines were determined for the current contamination levels at the site.

The precipitation of Be started at relatively lower pH at higher concentrations than at the lower Be concentration as indicated by both laboratory data and simulation. Across the pH range, the Be sorption curve was divided into three phases, these being pH 3-6, pH 6-10, and pH > 10, within which sorption of Be with soil was 9-97%, 90-97%, and 66-90%, respectively. Beryllium solubility was limited at pH > 7, but a sorption study with soil showed chemisorption under both acidic and alkaline pH (pH 5.5 and 8) conditions, which was confirmed by FTIR and XPS analysis. At pH 5.5 (specifically relevant to the study site), sorption of Be was 72-95%, in which 77% and 46% Be was respectively sorbed by separated fulvic and humic acid fractions. The irreversible chemisorption mechanism was controlled by SOM at higher pH, and by metal oxyhydroxides at lower pH.

Variable surface charges developed by different added ions (competing ions, counter ions, and co-existence of all ions) were not always correlated with Be sorption. However, effects of added ions in Be sorption (increased by counter ions and decreased by competing ions) primarily occurred at low pH, with no noticeable changes at pH > 6 due to the hydration and precipitation behaviour of Be at higher pH. Both laboratory data and modelling indicated the substantial effect of counter ions on increased sorption of Be. Relatively higher amounts of sorption under the co-existence of all added ions were suggested from synergistic actions. Sorption was favourable (KL > 0, and 0 < RL < 1) across all concentrations and temperatures at pH 5.5, and high retention (84–97%) occurred after four desorption cycles indicated specific sorption. The sorption process was exothermic (ΔH > −43 kJ mole−1), while desorption was endothermic (ΔH > +78.4 kJ mole−1). All sorption–desorption reactions were spontaneous (ΔG = −Ve), and executed without any structural deformation (ΔS = nearly zero) of soil particles. However, the effect of temperature on desorption was influenced by the concentrations of Be. Higher retention and different sorption–desorption parameters (Kd-desorption > Kd-sorption; Kf-desorption > Kf-sorption; ndesorption/nsorption < 1) indicate limited mobility of Be and the presence of desorption hysteresis in the studied soil under the experimental conditions.]]> Wed 07 Feb 2024 14:36:35 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:52951 Wed 07 Feb 2024 14:35:17 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:51661 Wed 07 Feb 2024 14:30:45 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:50508 Wed 07 Feb 2024 14:28:38 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:51885 Wed 07 Feb 2024 14:25:54 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:54640 Wed 06 Mar 2024 15:11:40 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:54621 Wed 06 Mar 2024 10:53:01 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:53426 Wed 03 Apr 2024 14:49:40 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:55019 Wed 03 Apr 2024 13:23:06 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:50685 Wed 01 May 2024 15:09:13 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:39295 1) and carcinogenic risks (CR > 1.0 × 10−4) increased with increasing Cd levels in the soil.

The soil types with added Zn and Cd exerted a significant effect on translocation and accumulation of metals in different tissues. The accumulation of Zn and Cd was higher for Tenosol than that for Dermosol. At control, the concentration of Cd followed a pattern, e.g., root > stem > petiole > pod > leaflet > grain for both soils. A basal Zn supply (5 mg kg^-1) increased the grain Zn concentration to a significant amount (up to 67%). It also reduced Cd accumulation in tissues, including grains (up to 34%). No non-carcinogenic effect was observed for either the children or the adults as the EDI and PTDI values were below the safety limit; however, the ILCR values exceeded the safety limit, indicating the possibility of some carcinogenic effects. Added Zn helped to reduce the carcinogenic and non-carcinogenic health risks on humans.]]> Fri 03 Nov 2023 16:05:28 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:52954 Fri 03 Nov 2023 11:04:28 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:53514 coal tar > pitch. Increases in Frap of cPAHs were observed in coal tar-treated soils after 48 d soil incubation (0.33%–1.16% for soil M, p ≥ 0.05, 6.24%–9.21% for soil G, p < 0.05) and was attributed to the continuous migration of coal tar as a non-aqueous phase liquid (NAPL) into soil pore structures. Slow desorption was dominated by source materials, whereas the extents and rates of rapid desorption (Frap and krap) were more controlled by the quantity of soil organic matter (SOM), rather than quality of SOM (as in solvent-spiked soils). The results of this study challenged the role of PAH source materials as ‘sinks’ and led to the proposed roles of coal tar and pitch and source materials alike as ‘reservoirs’ with a risk-driven perspective.]]> Fri 01 Dec 2023 10:58:45 AEDT ]]>
