Abstract ：
Microplastics (MPs) and heavy metals (HMs) are pervasive pollutants in aquatic environments posing significant ecological and human health risks. Current research typically evaluates the risks associated with MPs and HMs separately, potentially underestimating their combined effects and leading to the implementation of ineffective mitigation strategies. This study introduces a novel machine learning framework to quantitatively assess both, the accumulation-based and synergistic risks arising from the interactions between MPs and HMs in river sediments. The results indicate that clay content exhibits a significant positive correlation with MPs accumulation (estimate = 0.61, 95% confidence interval (CI)= [0.29, 0.94]), while the silt content is negatively correlated (estimate = -0.05, 95% CI = [-0.09, -0.02]). Feature importance analysis revealed that polyethylene (PE) is the most influential in predicting the presence of Hg, with moderate effects on Ni and Cd, polypropylene (PP) has a high affinity for Hg, Ag, and Ni, and polyamide (PA) exhibits the strongest association with Cd. The integrated risk model quantified the synergistic risks of MPs and HMs, showing that HMs risk index contributed more significantly to the overall risk, accounting for approximately 93%. Although MPs only contribute 6% to the synergistic risks, their role as substrates for pollutant release and accumulation should be highlighted. The study outcomes provide crucial knowledge for better understanding the dynamics of multiple pollutant interactions and their long-term risk implications for the formulation of effective mitigation strategies. The methodology presented is versatile and can be applied to other environmental media to investigate the risk arising from the interactions between different environmental pollutants. © 2025, The Authors.

Abstract ：
The waste activated sludge (WAS) exhibits typical viscoelasticity due to the presence of viscous and gelling organics in extracellular polymeric substances (EPS). However, the positive role of reducing viscosity in WAS fermentation by degrading viscous polysaccharides has been historically overlooked. This work demonstrates the occurrence of viscous hyaluronan-like polysaccharides in the WAS for the first time. Approximately 6.8 % of bacteria, such as Zoogloea (1.0 %), were identified as the potential producers. The viscosity of hyaluronan could be significantly reduced by 99 % within 1 hour by the oriented hyaluronan-degrading consortium (HDC), and a reduction of 20 % was also observed for WAS after 24 h. This resulted in a 18 % improvement in methane production and a 35 % improvement in the maximum production rate in WAS fermentation. The conversion of viscous hyaluronan was mainly through the hyaluronan lyase (EC 4.2.2.1) dependent pathway. An unfamiliar genus of Paludibacter (9.6 %) was identified as a key bacterium, responsible for excreting five extracellular enzymes of EC 4.2.2.1, EC 3.2.1.35, EC 3.2.1.31, EC 3.2.1.52, and EC 3.2.1.180. Consequently, this study has elucidated reducing viscosity as a substantial factor in WAS fermentation by the oriented HDC, thus providing a novel paradigm to enhance methane production.

Abstract ：
Wastewater treatment significantly contributes to greenhouse gas emissions,which are further exacer-bated by the environmental impact of external chemical additions.In response,microbial electrochemi-cal wastewater refining has gained prominence at the interdisciplinary frontier of wastewater resource recovery and green bio-manufacturing.Significant progress has been made in utilizing active electrodes to stimulate CO2 fixation rates,applying"binary electron donors"to produce high-value-added chemi-cals,and developing novel processes and equipment.This review explores various aspects of microbial electrochemical wastewater refining,including microbial electrochemical monitoring of water quality,chemical synthesis from diverse carbon sources,and the deployment of pilot-scale systems for generat-ing electricity,hydrogen,and methane,as well as for in-situ remediation.Additionally,it discusses the challenges and future directions,highlighting the importance of understanding mechanisms,advancing electrocatalyst and microbial engineering,and innovating hybrid processes.In conclusion,the wide-spread adoption of microbial electrochemical wastewater refining is emphasized for resource recovery and sustainable chemical production,ultimately reducing environmental impact.

Abstract ：
The distribution and transformation of water content critically influence sludge dewatering performance and remain central to sludge treatment research. Low-field nuclear magnetic resonance (LF-NMR), known for its nondestructive and rapid analysis, has emerged as a vital tool for characterizing water distribution in sludge, though its limitations require further investigation. This study employed LF-NMR to analyze T2relaxation spectra of sludge under various pretreatments and with differing water contents (97 %-62 %). Results indicated that, despite similar overall water content, sludge subjected to different pretreatments exhibited significant variations in T2peak counts and times. Notably, T2,, T22, T2s, and T2a showed significant exponential relationships with water content (p < 0.0001). The transformation and migration of adsorbed, interstitial, and free water demonstrated complex bidirectional continuity. Removal of adsorbed and interstitial water significantly altered sludge structure, diminishing the reversibility of water reabsorption, whereas removal of free water had minimal impact on microstructure. Overlapping T2relaxation peaks suggested continuous transitions among water states, challenging the traditional discrete categorization. Neglecting changes in T2 peak times may lead to misinterpretation of water states and affect assessments of dewatering performance. While LF-NMR shows great potential, its limitations in resolving overlapping peaks and quantitatively assessing water states must be acknowledged. Consequently, LF-NMR should be regarded as a qualitative or semi-quantitative method rather than a purely quantitative tool as often assumed. Future research should integrate higher-resolution T,-T2two-dimensional NMR techniques with advanced data processing to more accurately elucidate the mechanisms of water migration and transformation within sludge.
