Summary: Adding GAC-NZVI particles into anaerobic system with 0.10 V direct voltage was found to enhance CH4 production process. The measurements showed that the particles promoted the secretion of EPS by microorganisms, which improved the floc strength of granular sludge and accelerated the metabolism of microorganisms. The results indicated that anaerobic treatment efficiency could be enhanced under the combined action of direct voltage and particles.

Summary: The combination of ZVI and GAC was found to enhance anaerobic digestion of pharmaceutical wastewater, increasing COD removal and methane production while reducing the levels of toxic compounds and biotoxicity. This was attributed to the establishment of direct interspecies electron transfer (DIET), which also led to changes in microbial community composition and pathways of methane production.

Summary: This study investigated the effect of hydrogenotrophic denitrification on cadmium (Cd(II)) removal and column life-span using hydrogen-autotrophic microorganisms and zero-valent iron (Fe-0) filled columns. The results showed that the nitrate-mediated bio-Fe-0 column had a higher Cd(II) removal efficiency and longer service life compared to the bio-Fe-0 and Fe-0 columns. This improvement was attributed to hydrogenotrophic denitrification, which caused more iron corrosion and more secondary mineral generation, providing more reaction sites for Cd(II) adsorption and immobilization. The distribution of reactive zone along the bio-Fe-0 column mediated by nitrate was found to be uneven, with the latter half part identified as a more active region for Cd(II) immobilization.

Summary: Efficient remediation of p-chloroaniline (PCA)-contaminated soil was achieved using activated persulfate (PS) with nanosized zero-valent iron/biochar (B-nZVI/BC) prepared by ball milling method. The concentration of PCA in soil decreased significantly from 3.64 mg kg(-1) to 1.33 mg kg(-1) under the conditions of 4.8 g kg(-1) B-nZVI/BC and 42.0 mmol L-1 PS. Further increasing B-nZVI/BC dosage and PS concentration to 14.4 g kg(-1) and 126.0 mmol L-1, the concentration of PCA reached 0.15 mg kg(-1) with a degradation efficiency of 95.9%. The study provides implications for cost-effective and environmentally friendly remediation of PCA-contaminated soil.

Summary: This study systematically investigated the effect of NO3- on the degradation of TCE by S-ZVI and its mechanism. The results showed that NO3- did not affect the degradation pathway of TCE, but at high concentrations, it competed for electrons and led to an increase in the production of acetylene. Additionally, the presence of NO3- promoted the formation of Fe3O4, which improved the degradation efficiency of TCE.

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.
