Summary: The supply of sulfate has been found to reduce the bioavailability of arsenic (As) and cadmium (Cd) in paddy soil contaminated with both metals. The effect of sulfate addition, however, varies depending on the soil environment, potentially due to differences in sulfate background levels. Additionally, the addition of sulfate stimulates the activity of sulfate-reducing bacteria, which can positively affect rice growth and physiological characteristics.

Summary: Although numerous studies on the stabilization of heavy metals in contaminated soil with iron-based materials have been conducted, the role of microorganisms in iron species and Cd speciation transformation has not been fully elucidated. In this study, 2-line ferrihydrite (MGE) and goethite (GE) were used to stabilize Cd in contaminated soil, and the microbial community characteristics were analyzed. The results showed that the application of MGE/GE decreased the exchangeable Cd and increased the iron-manganese oxide-bound and residual speciation. The abundance of Proteobacteria and Sphingomonas increased in the MGE group, while it decreased in the GE group.

Summary: The modification of sepiolite with ferric nitrate or iron-manganese oxide enhanced its ability to reduce both Cd and As accumulation in rice. The results showed that the modified sepiolites (NIMS and FMS) had larger specific surface areas than regular sepiolite (SEP), leading to better efficiency in reducing Cd and As content in brown rice. XPS analysis revealed that FMS enhanced the adsorption and co-precipitation of Cd, and facilitated the oxidation of As(III) to As(V). Additionally, both NIMS and FMS treatments improved soil conditions and limited the transfer of As to roots, showing promise for use in reducing Cd and As accumulation in rice.

Summary: In this study, zero-valent iron (ZVI) and anaerobic bacteria were used to remediate Cd(II)-polluted soil, mediated by sulfate (SO42-). The hydrogen-autotrophic sulfate reduction resulted in severe corrosion on sulfate-mediated biotic ZVI, forming massive corrosive products which played a crucial role in immobilizing Cd (II). Compared to the sulfate-mediated ZVI system, this integrated system achieved a 4.9-fold increase in aqueous Cd(II) removal and converted over 53% of easily available Cd(II)-fractions to stable forms. Increasing SO42- concentration and ZVI dosage showed a positive correlation with Cd(II) immobilization, suggesting the essential role of hydrogen-autotrophic desulfuration. It was found that hydrogen-autotrophic desulfuration could accelerate iron corrosion, promote reactive mineral formation, and generate CdS precipitates to effectively immobilize Cd(II). The reaction was favorable at neutral pH. This study highlights the promoted effect of hydrogen-autotrophic desulfuration on ZVI corrosion for Cd(II) immobilization and provides a practical technique for remediating Cd(II)-polluted soil.

Summary: The study investigated the role of Fe and Mn in immobilizing Cd in soil and reducing Cd uptake by rice using X-ray photoelectron spectroscopy (XPS) characterization and chemical analysis. The results showed that Fe and Mn loaded on biochar (BC-FM) enhanced the removal of CaCl2 extractable Cd from the soil and Cd in pore water compared to BC. The excellent adsorption performance of BC-FM, enhanced by Fe-Mn oxides, reduced the available Cd in the soil and inhibited Cd accumulation in rice, resulting in increased rice biomass and Cd concentrations within the national safety standard.

Summary: In this study, an integrated system of Fe-0 and hydrogenotrophic microbes mediated by nitrate (NMB-Fe-0) was established to remediate Cd(II)-contaminated sediment. The results showed that the system successfully immobilized and enriched Cd(II)(aq) on iron surface through the promotion of iron corrosion and increased biomineral production. The Cd(II)(aq) removal rate in the NMB-Fe-0 system was much higher compared to the NM-Fe-0 system, and the leachability of Cd(II) decreased significantly while the residual fraction increased.

Summary: Microbial-induced carbonate precipitation (MICP) is a promising technology for immobilizing/remediating heavy metals (HMs) like cadmium (Cd), but the long-term stability of MICP-immobilized HMs, especially in farmland where chemical fertilization is necessary, remains unclear. In this study, MICP treatment was performed on soils contaminated with various Cd compounds, and diammonium phosphate (DAP) was added to explore its impact on the immobilized Cd. The results showed that the addition of DAP could affect the stability of the immobilized Cd, and other treatments such as applying non-ammonium phosphate and adding lime material after soil acidification were also helpful in preventing the release of immobilized Cd.

Summary: Life in environments without photosynthesis relies on chemical energy, and understanding how chemical nutrients from the geosphere fuel chemosynthetic biospheres is crucial for studying life distribution and diversity. The study shows that basaltic glacial catchments have higher concentrations of dissolved H-2, leading to microbial communities with faster rates of H-2 oxidation and CO2 fixation. Differences in bedrock mineral composition can impact nutrient availability and microbial diversity, abundance, and activity.

Summary: This letter introduces and demonstrates a novel strain sensor based on four-sided modulated long period fiber grating (FM-LPFG). The CO2 laser's asymmetric refractive index modulation reduces the cladding radius and strengthens the core deviation effect. Additionally, the strain sensitive area of FM-LPFG is proposed through simulating the equivalent strain during tension. The measurement results show that the strain sensitivity of FM-LPFG is 127.5 pm/με (0 to 125 με) and 17.7 pm/με (125 to 575 με). The proposed FM-LPFG can be realistically applied in precision measurement.

Summary: This study found that microplastics are widely detected in the gut of black soldier flies (BSFs), causing gut cell damage, inflammation, and fecal hardening, which hinders organic mineralization and antibiotic degradation. Microplastic intake significantly reshapes the microbial community structure and promotes the colonization of pathogenic bacteria carrying antibiotic-resistant genes, leading to the enhancement of antibiotic resistance. Therefore, isolating microplastics in feces before insect transformation is necessary.

Summary: A novel tapered two-mode fiber embedded long period fiber grating (TTMF-LPFG) sensor is proposed, which shows high sensitivity with a smaller diameter and low sensitivity to temperature. Traditional taper fiber requires a very thin waist to excite a strong evanescent field (EF) for large RI sensitivity, making the sensor fragile. In contrast, the TTMF-LPFG structure allows for LPFG formation and improved sensitivity through tapering, making it suitable for chemical composition analysis and biomedical applications.

Summary: This study investigates the effects of different forms of nitrogen fertilizer on the reduction and dissolution of arsenic-bearing iron minerals and microbial-mediated arsenic transformation processes. The results show that nitrate nitrogen fertilizer reduces the bio-availability of arsenic in soil, while ammonium nitrogen fertilizer promotes the release of arsenic into porewater. However, the combined application of nitrate and ammonium nitrogen has no significant effect on arsenic concentration in rice grain and its transformation in paddy soils. These findings provide insights into the rational use of nitrogen fertilizers to reduce the risk of arsenic contamination in rice.

Summary: Microplastic contamination is widespread in aquatic environments, with increasing plastic production leading to a rise in microplastic pollutants released into the environment. These plastic particles can absorb various chemical pollutants and contribute to toxin accumulation in the food chain. This study investigated the adsorption behavior of aniline, a priority environmental pollutant, on polystyrene microplastics (mPS). The results showed that mPS had a maximum adsorption capacity of 0.060 mg/g, with equilibrium reached after 24 hours. The adsorption kinetics followed a pseudo-second-order model and the Freundlich model described the adsorption isotherms. The adsorption mechanisms may involve 7C-7C interactions and hydrophobic interactions. Factors such as pH, ionic strength, and temperature of the solution played significant roles in the adsorption process.

Summary: Phase map filtering is a crucial process in speckle interferometric optics measurement. The conventional sine-cosine domain filtering framework consumes a significant amount of calculation resources, limiting the temporal property of measurements. To address this issue, a new filtering domain called complex amplitude domain filtering is proposed. This domain offers a good filtering efficiency, preserves details, and does not generate additional phase shifts during filtering. Preliminary experiments show that the proposed complex amplitude domain filtering accelerates the filtering process by at least 40% without sacrificing filtering quality, especially with the PDE noise reduction method.

The combination of both processes proves to be more effective than adsorption and ozonation alone. Ozonation improves the adsorption performance of poorly-oxidizable CECs but worsens that of well-oxidizable compounds. This research highlights the importance of considering both processes in the removal of CECs in drinking water treatment plants.
