Summary: The cultivation of different aquatic plants in sediment can affect the sorption-desorption behaviors of phosphorus, with differences observed between submerged plants like Hydrilla verticillata and emerged plants like Scripus triqueter. The study suggests that the growth of submerged plants may enhance P retention capacity and reduce release risk in sediments.

Summary: This study investigated the fate of dissolved organic matter (DOM) in the sediment during electrokinetic remediation (EKR) using multiple spectroscopic tools. The results showed significant electromigration of alkaline-extractable DOM toward the anode, followed by transformation of aromatics and mineralization of polysaccharides. The water-extractable organic matter increased at both electrodes, likely due to pH-driven dissociations. Nitrogen migrated with the alkaline-extractable DOM, but phosphorus remained immobilized. Understanding the redistribution and transformation of DOM in EKR is important for studying contaminant degradation, carbon and nutrient availability, and sediment structural changes.

Summary: Microplastics added to soils in different regions of China significantly alter the composition of soil organic matter, with a more pronounced effect in lower latitudes. The impact of microplastics on soil organic matter is long-lasting under long-term treatment. Additionally, nutrient availability and latitude-related climatic variables are associated with the degree of microplastic input on soil organic matter.

Summary: Periphyton is a significant source of dissolved organic matter (DOM), especially in wetland environments like the Everglades. This study analyzed the composition and characteristics of DOM produced by periphyton and compared it with DOM in surrounding surface water. The results showed that periphyton significantly contributes to DOM production and leaching, and the type of periphyton affects the production and composition of DOM.

Summary: The study reveals that stormwater runoff has an impact on the concentration of dissolved organic matter (DOM) in Shili River, Jiujiang, China, particularly in the middle reaches. Critical pollutants and DOM concentrations increased due to the runoff. Three humic-like and two protein-like components of DOM were identified using 3DEEM-PARAFAC and UV-Vis spectroscopy. DOM mainly originates from autochthonous sources and is minimally affected by runoff.

Summary: The study investigates the in vitro biotransformation rates of eight biocidal and one pharmaceutical anticoagulants in rainbow trout liver subcellular S9 fraction. The results show that four of the tested substances exhibit significant intrinsic clearance in the assay, and the metabolism is slow and temperature-dependent. However, further research is needed to determine the influence of in vitro biotransformation rates on the prediction of bioconcentration factors.

Summary: This study investigates the design and performance of a multistage surface-heated vacuum membrane distillation (SHVMD) system with heat recovery. The results show that surface heating enhances the performance of SHVMD compared to conventional vacuum membrane distillation (VMD), achieving higher water recovery and gained output ratio (GOR). The internal and external heat exchangers capture and reuse additional heat, further improving the GOR values. Additionally, surface heating reduces the energy consumption of membrane distillation for brine concentration.

Summary: Early and effective fault detection is important for maintaining water quality and preventing disruptions in water and wastewater treatment plants. This paper applies functional data analysis (FDA) to detect drift faults in a sequencing batch membrane bioreactor and a closed-circuit reverse osmosis system. FDA enables the analysis of cyclic data and identifies unusual functions by comparing them to a reference set.

Summary: Unsupervised process monitoring for fault detection and data cleaning in wastewater treatment plants is underdeveloped due to the complexity and volume of data. This study evaluates the performance of the adaptive dynamic principal component analysis (AD-PCA) method in detecting faults in a decentralized WWTP. The results show that implementing AD-PCA with appropriate parameters can detect faults prior to existing operational thresholds, although further work is needed to improve its consistency in real-time fault detection.

Summary: The study showed that membrane bioreactors (MBRs) exhibit excellent long-term performance in removing organic constituents from produced water (PW), even in high salinity conditions. MBRs were effective in removing dissolved organic carbon from PW from different shale basins, but showed less consistent removal of surfactants. The study also found that microbial diversity decreased during reactor establishment but increased at higher total dissolved solid (TDS) concentrations.

Summary: NO2 emissions from wall-mounted gas stoves used for household heating have become a significant source of indoor pollution in Chinese urban areas. The high indoor concentration of NO2 poses potential health risks to residents. It is urgently necessary to establish relevant regulations and implement emission reduction technologies to reduce NO2 emissions from wall-mounted gas stoves.

Summary: This study investigates the relationship between dissolved organic matter (DOM) and Rare Earth Elements (REEs) in sediments from Yundang Lagoon, China. The results show four distinct fluorescent components, with protein-like substances being the most prevalent. Additionally, the total fluorescence intensity and LREE concentrations exhibit a synchronized increase from Outer to Inner to Songbai Lake core sediments. The findings demonstrate a strong correlation between DOM content and pollution levels.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: The choice of workflow in wastewater surveillance has a significant impact on SARS-CoV-2 concentrations, while having minimal effects on HF183 and no effect on HAdV 40/41 concentrations. Certain components in the workflow can be interchangeable, but factors such as buffer type, chloroform, and homogenization speed can affect the recovery of viruses and bacteria.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

The functionalized IVP showed a high mercury adsorption capacity and a machine learning model was developed to predict the amount of mercury removed. Furthermore, the functionalized IVP can be regenerated and reused, providing a sustainable and cost-effective adsorbent.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
