Summary: This study demonstrates the potential of green rust (GR) in treating arsenic (As) contamination in groundwater. Lowering temperature or adding arsenic can increase the stability of GR, reducing the solubility of arsenic and effectively immobilizing it in the mineral. This ultimately improves the efficiency of arsenic remediation.

Summary: Ni-Fe layered double hydroxide (LDH) catalysts with varying oxygen evolution reaction (OER) performance were synthesized using a facile chloride corrosion method. The catalysts prepared with ferric salts exhibited enhanced OER performance compared to those prepared with ferrous salts, attributed to the formation of Ni-Fe LDH and additional FeOOH.

Summary: This study investigates the synthesis approaches of green rust (GR) and bone char (BC) composites and their impact on composite reactivity, electron efficiency, and shelf-life. The results show that increasing the BC content improves the reaction rate, while changes in GR content and Fe-II/Fe-III ratio have little effect. The use of persulfate in the synthesis allows better control of the Fe-II/Fe-III ratio and enhances the long-term stability of the composite.

Summary: Researchers have developed a generic protonation parameters model to describe the surface reactivity of iron (hydr)oxides in soils and sediments. The model has been tested and validated with various iron (hydr)oxides and provides good predictions of their proton reactivity in electrolyte solutions. This generic model simplifies the study of iron (hydr)oxides and does not require spectroscopic measurements or proton titrations.

Summary: This study presents a facile method for synthesizing ultrathin CoFe-based LDHs and reveals their high performance in OER. The Co site is identified as the main active center, and the doping of Fe accelerates the charge-transfer process. Surface Co sites are found to be the active centers for OER, while excessive subsurface Fe doping weakens OH* adsorption and increases the energy barrier of the rate-determining step.

Summary: This study evaluated the variations in extractable-P in soils under different redox conditions. The results showed that the solid to solution ratio and bicarbonate concentration significantly affected the extraction of phosphate, with more phosphate extracted under anoxic conditions. The effect of bicarbonate concentration was more pronounced in soil samples with higher organic carbon content. The CD-MUSIC model successfully predicted the effect of solid to solution ratio on extractable-P under both oxic and anoxic conditions.

Summary: Nickel-iron based hydr(oxy)oxides are recognized as excellent oxygen-evolving catalysts, but iron leakage during operation can cause deactivation. In this study, a NiFe-based Prussian blue analogue precursor was used to fabricate a highly active hydr(oxy)oxide catalyst with Ni-Fe synergic active sites. The resulting catalyst demonstrated low overpotentials and robust stability under large current conditions. This work provides a feasible strategy to design active and durable catalysts through self-adaptive reconstruction engineering.

Summary: In this study, unique layered Fe(III)-Cr(III) oxides were formed during the Cr(VI) removal by sulfate green rust (GRSO4). The layered structure of GRSO4 remained intact after fast reduction of Cr(VI). Further reduction of Fe(III) to Fe(II) using sodium dithionite resulted in stable Fe(II)/Fe(III) cycle in the hexagonal plates. The study observed better crystallinity at higher Fe(III) reduction rate and confirmed the layered metal oxide structure. Multiple treatment cycles showed increased Cr(III) loading on the layered Fe(III)-Cr(III) oxides. The study provides new evidence and insights for formulating strategies to eliminate Cr(VI) or related heavy metals.

Summary: Systemic insecticides and rising temperatures have combined effects on the abundance of Odonata nymphs in paddy fields. The standalone effect of insecticide exposure decreased the Odonata community, while nymphs decreased synergistically with temperature rise in paddy water. However, the impacts of each stressor alone varied among species.

Summary: The Arctic region is facing contamination from long-range pollution and local human activities. Polycyclic Aromatic Hydrocarbons (PAHs) are used as environmental indicators for emission, transport, and deposition processes. Research conducted in the Arctic surface snow in Ny-Ålesund, Svalbard from October 2018 to May 2019 shows that long-range inputs of PAHs mainly occur in winter, while the most abundant analyte retene exhibits opposite seasonal trends.

Summary: In this study, a human physiologically based pharmacokinetic (PBPK) model of diethyl phthalate (DEP) was developed to assess its toxicity. The model considers the distribution and metabolism of DEP and its active metabolite monoethyl phthalate (MEP) in different tissue compartments. Sensitivity analysis and Bayesian Markov chain Monte Carlo (MCMC) simulations were performed to evaluate the uncertainty and variability of the model parameters. The results suggest that dermal absorption is an important route of exposure to DEP in the environment.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.

Summary: This study investigates the impact of biochar on methylmercury (MeHg) accumulation in rice. The results show that biochar reduces MeHg levels in paddy soils by decreasing bioavailable Hg and microbial Hg methylation. Additionally, biochar decreases the uptake and translocation of MeHg in rice plants, resulting in a reduction of MeHg accumulation in rice grains.

Summary: This study aims to explore the effects of thiencarbazone-methyl center dot isoxaflutole on soil microflora and the potential mitigation mechanisms to bacterial communities. It was found that increasing the application of thiencarbazone-methyl center dot isoxaflutole resulted in increased stress on soil bacterial community structure and diversity. Increasing soil pH was recognized as a key factor in improving the diversity and structure of soil microflora. Supplemental use of nitrapyrin or modified attapulgite can increase soil pH and improve bacterial diversity.
