Summary: A nitrogen deficiency can hinder bioremediation efforts in mining regions, with diazotrophs potentially playing a crucial role in supporting plant and microbial growth. This study compared diazotrophic communities in highly contaminated and moderately contaminated mining sites, revealing a loosely connected biotic interaction induced by antimony and arsenic co-contamination. Rhizobium was identified as a key taxon resistant to Sb and As contaminants in the vertical profile of contaminated soil, suggesting its importance in nitrogen fixation within these environments.

Summary: This study investigated the community composition of arbuscular mycorrhizal fungi (AMF) in antimony (Sb)- and arsenic (As)-polluted soil using morphological and molecular identification methods. The main factors influencing AMF community composition in these polluted areas were explored. The results showed that the majority of the AMF community belonged to Glomeraceae, and the affinity between AMF and plants was mainly related to plant species and not significantly correlated with Sb and As content in soil. Soil nutrients had a greater impact on AMF community composition than Sb and As content, and the effect of As on AMF community composition was exacerbated by the interaction with phosphorus in the soil.

Summary: This study explored the microbial communities in river sediments impacted by accidental antimony (Sb) spill, revealing higher relative abundance of Proteobacteria and Actinobacteria in Sb-polluted sites. Under Sb stress, microbial functions related to DNA repair and ion transport were enhanced, along with an increase in heavy metal resistance genes, particularly the arsB gene. Horizontal gene transfer may contribute to the increase in heavy metal resistance genes and antibiotic resistance genes at Sb spill-impacted sites.

Summary: Microbial fuel cells (MFCs) have been shown to effectively remove tetracycline in soil by enhancing degradation efficiency and reducing antibiotic resistance genes through the addition of phosphate. Specific bacteria like Geobacter, Desulfurispora, and Anaeroomyxobacter play key roles in bioelectricity generation in the anode, while Gemmatimonadetes bacterium SCN 70-22 and other potential electrotrophic microbes are identified in the cathode. The expression of flavoproteins and enzymes like quinol oxidase in the cathode can improve electron transfer efficiency and accelerate the biodegradation rate of tetracycline.

Summary: Arsenic and antimony removal from mining-affected waters in Northern Finland is efficiently carried out by two treatment peatlands (TPs). The study investigates the role of peat microorganisms, temperature, and carbon substrate in the removal process using microcosm experiments and pilot-scale TPs. Microbes were found to catalyze the reduction and oxidation of As and Sb species in the TPs, with temperature being a major influencing factor. Low inflow concentrations, long water residence times, and the presence of unfrozen peat in lower layers contribute to efficient removal even under winter conditions.

Summary: Arsenic contamination can affect the adaptability of soil microbial communities and their metabolism genes. Arsenic metabolism genes are prevalent in soil profiles at different contamination levels, with their abundance influenced by the concentration of metal contaminants, and some genes increasing in abundance in deep soil layers. The distribution of host microorganisms for arsenic metabolism genes is also affected by different levels of metal contamination.

Summary: This study explores the characteristics of intestinal microbes in cavefish and surface fish, and establishes the relationship between intestinal microbes and habitat microbes. The results show that the structure of intestinal microbes in cavefish and surface fish is more related to habitat type rather than genetic relationships. Differences in gut microbes may enhance the adaptability of these two fish types, involving food intake, nutrient utilization, harmful substance metabolism, etc., further demonstrating the link between food resources, predation patterns, intestinal flora, digestive and absorptive capacity, and feeding habits and preferences with habitat adaptability.

Summary: In this study, the researchers investigated the temperature-dependent variations in the char-volatile products derived from sludge and microplastics under different pyrolysis scenarios. They found that the abundance of EPFRs increased exponentially in the 350-450 degrees C range. The formation of EPFRs was found to be temperature-dependent, and microplastics with conjugated aromatic ring structures were more likely to form EPFRs.

Summary: Conversion of sewage sludge to biochar for contaminants removal achieves the goals of solid waste reuse and pollution elimination. However, the understanding of sludge-derived biochar (SDB) for wastewater treatment is still limited. This paper reviews recent studies on the use of (modified) SDB as adsorbents and catalysts for the removal of contaminants from water. It summarizes the effects of modification on the adsorption and catalytic performance of SDB and discusses the challenges and future directions in using SDB for wastewater treatment.

Summary: Despite extensive research on semiconductor photocatalysis, the fundamental aquatic chemistry of these new materials and their environmental implications are poorly understood. In this study, the solubility of BiVO4 and its non-stoichiometric dissolution in different pH ranges were investigated. The solubility and stability of BiVO4 were found to be pH-dependent, with the lowest solubility and highest stability near pH 5. Illumination significantly enhanced the dissolution of BiVO4. Adsorption of dissolved bismuth by BiVO4 solids was identified as the main reason for the non-stoichiometric dissolution. These findings highlight the importance of considering the dissolution of photocatalysts and provide a method to evaluate the environmental stability and risks of other semiconductor materials.

Summary: This study focused on the pyrolysis of sludge and used in-situ infrared/mass spectral probes coupled with signal amplification techniques to analyze the reactions and dynamic variations during pyrolysis. By comparing different samples, the three-stage pyrolysis of sludge and its reaction mechanisms were identified. The generation of reactive intermediates and collision frequency between reactants played important roles in the pyrolysis process, and the order of volatile generation was consistent with the variations of pyrolysis behaviors, reaction models, and surface characteristics of chars.

Summary: This critical review discusses the synthesis methods of nanomaterial adsorbents (NAs) and assesses their scalability for full-scale applications. It also examines the impact of NAs structures on metal adsorption and emphasizes the need to prioritize research to balance production costs and feasibility of desired properties at commercial scale quantities. Furthermore, it suggests the establishment of an evaluation protocol for NAs to consider both adsorption capacity and mass transfer kinetics during material discovery stage and long-term testing in real applications.
