Summary: The aim of this study was to evaluate the effectiveness of biochar and montmorillonite islands in immobilizing heavy metals during chicken manure composting. Biochar showed higher enrichment ability for Cu and Zn compared to montmorillonite, which could be attributed to its active functional groups. Network analysis and Structural Equation Model revealed the crucial factors driving heavy metal adsorption were dissolved organic carbon, pH, and bacteria. Pretreatment methods, such as soaking in a DOC-rich solution and inoculating specific microbial agents, could improve the effectiveness of adsorptive passivation on heavy metals.

Summary: The roller experiments revealed that nano-silver could dose-dependently suppress the formation and aggregation of marine snow particles, resulting in thinner and more compact particles. Additionally, nano-silver altered the species composition and functional profile of the microbial community, inhibiting the growth of most abundant species and key biological processes. This strong microbial inhibition contributed to the suppression of marine snow formation, particularly by reducing the genes related to extracellular polymeric substance synthesis and secretion.

Summary: The hepatocytotoxicity and aryl hydrocarbon receptor (AHR) activity of decabromodiphenyl ethane (DBDPE), decabromodiphenyl ether (BDE209) and other 18 analogues were evaluated in vitro using human normal liver cell L02. The AHR signaling pathway was found to be the key mediation mechanism for the hepatotoxicity of DBDPE/BDE209. Formation of reactive oxygenated intermediates by cytochrome P450s (CYP2 family) was identified as the dominant toxic mechanism. The health risk of DBDPE may be greater than expected due to the potential formation of dioxin-like intermediates through microbial oxidation of the ethyl group.

Summary: This study investigates the differences in responses between cyanobacteria and green algae, which are the recommended test organisms for toxicity assessments, to the same chemical. The results show that these two species have different resistance mechanisms and can alleviate the toxicity of sulfamethoxazole through different pathways. Inconsistent assessment results for antibiotics using cyanobacteria and green algae are likely due to their different resistance mechanisms. Improved indicators or comprehensive assessment methods should be considered for environmental toxicity assessments.

Summary: This study described the compositions of sediment bacterial communities in the urban riverbank over the spatial gradient. Different types of effluents affected the bacterial community in different regions. Parameters such as NH4+-N, organic matter, effective sulphur, electrical conductivity, and total dissolved solids were correlated with higher microbial richness and biodiversity. Organic matter, total nitrogen, NH4+-N, NO3-N, pH, and effective sulphur were identified as important drivers for bacterial community distribution. Proteobacteria was the predominant phylum in sediments, with Serratia as the dominant genus. Sulphate-reducing bacteria, nitrifiers, and denitrifiers were detected at sites and closely related to contaminants. This study expanded our understanding of the impact of municipal effluents on microbial communities in riverbank sediments and provided valuable information for further exploration of microbial community functions.

Summary: In this paper, the interaction of silver nanoparticles (Ag-NPs) with marine/lake snow in the early formation stage was investigated. Results showed that Ag-NPs promoted the accumulation of larger marine snow flocs while inhibited the development of lake snow. The promotion effect of Ag-NPs was attributed to their oxidative dissolution into silver chloride complexes in seawater and incorporation into marine snow, while Ag-NPs in lake water existed as colloidal nanoparticles and suppressed the growth of lake snow due to their strong antimicrobial effect. Furthermore, Ag-NPs also affected the microbial community of marine/lake snow, including impacting microbial diversity and elevating the abundances of extracellular polymeric substances synthesis genes and silver resistance genes.

Summary: A study investigated the biological effect of titanium nanomaterials in a sequencing batch reactor (SBR) by adding various doses of titanium dioxide (TiO2) and titanate nanotubes (TNTs). The results showed that both TNTs and TiO2 had a moderate suppressing effect on SBR performance, with TiO2 being more toxic. High-throughput sequencing and analysis revealed changes in the microbial community composition in the SBR caused by the two titanium nanomaterials, with genus Hylemonella identified as the biomarker contributing the most to the community response. Metagenomic analysis showed that the presence of nanomaterials downregulated metabolic pathways related to metabolism and led to the degradation of xenobiotics and pollutants, which correlated with the decrease in treatment performance of SBR. Exposure tests with Escherichia coli and Pseudomonas taiwanensis demonstrated the nanotoxic mechanisms of TiO2 and TNTs, including interactions with the microbial cell surface and elevation of cellular reactive oxygen species (ROS) levels. These nanotoxic effects could also be attributed to enhanced community functions.
