Summary: The environmental conditions of groundwater and surface water vary greatly depending on the location, which can affect the physical and chemical properties of nanocomposites and pollutants used in remediation. In this study, magnetic nanocomposite microparticle (MNM) gels were used as sorbents for remediating PCB 126 as a model organic contaminant. The effects of ionic strength, water hardness, and pH on the sorption efficiency of the MNMs for PCB 126 were studied. The results showed that ionic strength and water hardness had minimal effects on the sorption of PCB 126 by MNM gels, while an increased pH resulted in a decrease in binding, likely due to anion-pi interactions.

Summary: Recent studies have shown that unintentionally produced PCBs are major contributors to atmospheric PCBs and are controlling PCB burdens in agricultural soils across China. The dominant contributors to PCBs in Chinese agricultural soils are the legacy of historically produced and used commercial PCB mixtures, especially high-chlorinated congeners. Unintentional sources, such as pigment/paint, combustion-related sources, and polymer sealants, account for a significant portion of total PCBs in Chinese soils.

Summary: Two new classes of PCB metabolites, sulfonated-polychlorinated biphenyls (sulfonatedPCBs) and hydroxy-sulfonated-polychlorinated biphenyls (OH-sulfonated-PCBs), have been recently discovered. They are more polar than their parent compounds, but little is known about their chemical identity, ecotoxicity, or toxicity. This study provides the first evidence on the fate of these metabolites in the environment and presents results from various experiments to evaluate their soil partition coefficients, degradation after rhizoremediation, uptake by plants and earthworms, and an analytical method for extracting and concentrating these compounds from water.

Summary: This study found that biochar can reduce the bioavailability of soil microelement zinc and limit its uptake by rice. Increasing application rate of biochar improves rice growth and soil electrical conductivity. Biochar can also limit the enrichment of DTPA-extracted zinc in <0.25mm soil aggregates and enhance the transformation of acid extractable zinc into reducible and oxidizable forms.

Summary: The study assessed the reduction of rice nickel concentration and oral bioavailability through rice iron biofortification and dietary iron supplementation. Results showed that increasing rice iron concentration led to a decrease in nickel concentration due to inhibited nickel transport. Fe-biofortified rice had significantly lower nickel oral bioavailability when fed to mice. Dietary amendment of iron supplementation also reduced nickel oral bioavailability through down-regulation of duodenal iron transporter expression. These findings suggest that iron-based strategies can effectively reduce rice-nickel exposure.

Summary: N-containing functional groups play a critical role in mediating As(III) oxidation by pyrogenic carbons. The oxidizing kinetics of As(III) were explained by the electron donating capacity and specific capacitance of low and high-temperature prepared pyrogenic carbons, respectively. The production of H2O2 and direct electron transfer were the main mechanisms of As(III) oxidation mediated by pyrogenic carbons.

Summary: This study investigated the effect of straw returning and nitrogen fertilizer application on hydroxyl radical formation in the surface water of paddy fields. The results showed that straw returning decreased hydroxyl radical formation, while nitrogen fertilizer application increased it. Correlation analysis revealed that dissolved organic matter and NO3- affected hydroxyl radical production in the early stage, whereas NO2- had a significant effect in the later stage. The decrease in NO3- and NO2- content after straw return may contribute to the lower hydroxyl radical formation in the amended paddy soil.

Summary: Oxygen nanobubble-loaded biochars have been found effective in reducing copper toxicity in paddy soils and improving crop productivity. This amendment improves the redox potential and dissolved oxygen concentration in the rhizosphere, promotes root iron plaque formation, and inhibits copper influx. It also enhances soil microbial diversity and increases bacterial genes abundance involved in copper complexation and export. The sequestered copper in root iron plaque and soil bacteria prevents its accumulation in edible parts of the plants.

Summary: Recently, the production of hydroxyl radical (&BULL;OH) during soil redox fluctuations has been reported, but the low efficiency of contaminant degradation hinders engineering remediation. This study found that the addition of low-molecular-weight organic acids (LMWOAs), such as oxalic acid (OA) and citric acid (CA), significantly enhanced &BULL;OH production during oxygenation of anoxic paddy slurries. The highest &BULL;OH accumulation was observed with 0.5 mM CA due to its strong capacity for complexation.

Summary: Alkaline-thermal coupling activation of persulfate (PS) is an effective method for hexachlorocyclohexane (HCH) degradation. In this study, the strategy of sequential addition of reagents was adopted to explore the effect of temperature and alkalinity on HCH hydrolysis and trichlorobenzene (TCB) oxidation. The results showed that high pH favored HCH hydrolysis but inhibited TCB oxidation. Sequential addition of reagents was found to be more beneficial for the degradation of HCH, especially at low alkalinity. Soils with low soil organic matter (SOM) content exhibited higher degradation efficiency.

Summary: Two types of Mn-modified biochar (MBC1 and MBC2) were prepared and found to efficiently remove As(III) from solution. MBC1 showed better oxidation and adsorption capacity than MBC2. The enhanced removal was attributed to the improved physicochemical properties of the biochar due to the presence of Mn-oxides, which promoted the adsorption of arsenic species and mitigated biochar surface passivation. The oxidation of As(III) via Mn(III) and Mn(IV) resulted in the production of As(V), which could then precipitate and be re-adsorbed on the biochar surface.

Summary: This study found that carbon materials have significant effects on the cycling of iron and the production of hydroxyl radicals in paddy soils. Under anoxic conditions, carbon materials facilitate the reduction of trivalent iron in soils, while under oxygenation, they promote the oxidation of active divalent iron, resulting in higher yield of hydroxyl radicals. This provides a new insight for remediation strategies in agricultural fields contaminated with organic pollutants.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
