Summary: This study demonstrates the impact of delayed tributary mixing in large boreal rivers on the properties and transport of Fe-bearing colloids, leading to significant differences in trace element concentrations. Adequate water quality monitoring in these rivers requires high-resolution spatial sampling due to the sensitivity of mixing behavior and water quality to hydrologic changes. Traditional monitoring approaches may be rendered unsuitable due to fluctuations in water quality and associated mixing behaviors.

Summary: Riverine dissolved iron (Fe) has significant impacts on water color, nutrients, and marine carbon cycling. The size and coupling of Fe with dissolved organic matter (DOM) play a crucial role in its biogeochemical function. This study investigated the drivers, concentrations, and fluxes of different fractions of dissolved Fe in the freshwater Connecticut River. The results showed that the concentrations and responses to discharge of colloidal and soluble Fe were different, with soluble Fe being strongly influenced by water temperature and coupled with humic-like DOM fluorescence component.

Summary: This study evaluated the separation ability of biased cyclical electrical field-flow fractionation (BCyElFFF) for polyvinyl pyrrolidone-coated and poly(ethylene glycol)-coated silver nanoparticles (AgNPs) with different electrophoretic mobilities, and elucidated the mechanism behind the formation of NOM corona on these AgNP surfaces. Furthermore, it was observed that the survival rates of E. coli exposed to AgNPs with or without NOM corona collected during repeated BCyElFFF runs increased with increasing NOM concentration, indicating the negative effect of NOM coronas on the bioavailability of AgNPs. These findings highlight the powerful capability of BCyElFFF in studying the fate and transformation of nanoparticles in aqueous environments.

Summary: The Otago Schist in New Zealand contains two types of tungsten mineralization, proximal and distal. The proximal mineralization occurs in sub- to lower-greenschist facies rocks and consists of quartz-calcite veins with minor scheelite and sulfides. The distal deposits are hosted in major crustal discontinuities within higher-grade metasedimentary rocks and are associated with abundant sulfides and gold. The scheelite in these two types of mineralization show geochemical differences, with the proximal occurrences being more heterogeneous in trace element and strontium isotope compositions compared to the more uniform scheelite in the distal deposits. The data suggest that tungsten mobility in the Otago Schist involved local-scale mobilization of W in the shallow crust followed by regional leaching and homogenization at higher temperatures.

Summary: This study investigated the distribution of several trace metals between five size fractions in the Krka River estuary. The results showed that the river was the dominant source for some metals, and dilution effect was observed for others. The truly dissolved fraction dominated certain metals, while others were mostly present in larger particles. The percentage of colloids varied with river flow, and this estuary had a limited input of terrigenous material compared to other coastal areas.

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: 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.
