Summary: This study investigated the accumulation, risk, distribution, and sources of heavy metals in 62 lakes along the Yangtze River. It found that most lakes were contaminated with Cd, with higher ecological risk in the middle reach and southern bank of the Yangtze River. The study also revealed that Cr originated from the natural environment, while Zn, Cu, Pb, Cd and As were affected by human activities.

Summary: Reliable quantitative information on sediment sources is crucial for river conservation and restoration. Sediment source fingerprinting is an independent field-based technique that identifies sediment sources in waterways. However, the lack of standardization limits its application in large-scale river basins.

Summary: This study examined the impact of radar-derived precipitation (RDP) and rain-gauge precipitation (RGP) on sediment prediction, finding that combining RDP led to better model performance by improving the accuracy of sediment yield predictions at higher resolution. This highlights the importance of considering the spatial variability of rainfall and assessing sediment production in order to improve predictions and reduce uncertainties associated with sediment simulations.

Summary: In this study, wavelet transformation method was used to analyze data from over 50 years at the Pingshan station on the Upper Changjiang River in order to identify the time-scale dependency of suspended sediment patterns. Short time scales are driven by climatic factors, while long time scales are controlled by high flow events and sediment storage within the river reach.

Summary: The Water Framework Directive establishes a framework for water policy in Europe and emphasizes the importance of monitoring sediment composition in surface water quality assessment. Sediment may carry dangerous substances that can harm living organisms, requiring continuous monitoring to protect the ecosystem. The Mura-Drava-Danube region aims to use the Transboundary Biosphere Reserve concept to promote both ecological conservation and sustainable economic development for local communities.

Summary: Sediment quality assessment is important for evaluating the quality of rivers and this study focuses on assessing heavy metal concentration in size-fractionated sediments of River Ganga and identifying sources of contamination. The results show that the sediments are contaminated and enriched with toxic metals, with Chinyalisaur, Devaprayag, and Rishikesh being classified as pollution hotspots. Natural sources contribute to aluminum and iron, while anthropogenic sources contribute to chromium, zinc, lead, nickel, copper, and cadmium. Immediate interventions are needed to control further contamination by restricting wastewater discharge into River Ganga.

Summary: This study investigated sediment yield in two catchment areas within the Lena River catchment using the WaTEM/SEDEM model. The predicted sediment yield was found to be in better agreement with measured values in the Yakutsk catchment area compared to the Chara catchment area. Additionally, the study found that the predicted sediment yield remained relatively stable over the period 1986-2019, while the suspended sediment yield at the Tabaga gauging station showed a slight increase.

Summary: The input of organic matter into stream channels is an important energy source for headwater ecosystems and plays a crucial role in the global carbon cycle. The study focuses on quantifying the mobilization, transport, and storage of organic-rich fine sediment in a Strahler fourth-order stream during intermediate-sized storm events. It is found that the channel bed is consistently a source of suspended load to the channel margins, and the trapping of suspended load by riparian margins limits sediment transport distance and decouples the channel from local terrestrial organic matter exchange.

Summary: Irrigation with reclaimed wastewater helps conserve freshwater sources, but also exposes agricultural products to emerging contaminants. A study in Israel found that the highest exposure to wastewater-borne contaminants occurred through the consumption of leafy vegetables. While no human health concerns were observed in average and high exposure scenarios, extreme exposure to certain contaminants from produce irrigated with reclaimed wastewater may pose a threat to human health.

Summary: One problematic outcome of soil erosion is sedimentation in stream channels. Reusing dredged sediments in agriculture can be a solution, but farmers are concerned about weed infestation. Research findings confirm the proliferation of weeds after using dredged sediments, and a protocol for assessing the need for weed management intervention is proposed.

Summary: Reclaimed wastewater containing CBZ can induce a stress response in tomatoes, especially in root tissues. While soluble sugars react to CBZ in both leaves and roots, stress-related amino acids and proteins show significant changes in roots but not in leaves. CBZ may weaken plant stress response but attract whiteflies due to increased sugar content in leaves, and it can also reduce the amount of TYLCV through autophagy activation.

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: 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.

Summary: In this study, inverse vulcanized polysulfides (IVP) were synthesized by reacting molten sulfur with 4-vinyl benzyl chloride, and then functionalized using N-methyl D-glucamine (NMDG). 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.
