Summary: This study investigated the impact of organic matter on the behavior of chromium during the iron(II)-catalyzed transformation of ferrihydrite. The results showed that organic matter inhibited the release and extraction of chromium during the transformation process, as well as the nanoscale conversion and re-immobilization of chromium. Therefore, organic matter plays an important role in the geochemical cycling of chromium in soils.

Summary: This study investigated the speciation of silicon in the clay-sized fraction of tropical soils. The results showed that silicon mainly existed in a beidellite structure and was adsorbed to montmorillonite and kaolinite. Si reference spectra had unique features that could differentiate different silicon forms. The extracted silicon amount was relatively low and correlated positively with pH, organic matter, and clay content in the soil.

Summary: This study investigates the impact of organic carbon (OC) binding strength on the aging of ferrihydrite and the fate of associated OC. It is found that OC substantially retards the aging process and that OC with higher binding strength becomes more stable with the solid phase during aging. The results provide insights into the mechanisms behind OC persistence with minerals and its long-term preservation in natural environments.

Summary: This review focuses on the surface colloidal properties of iron oxides and their reactivity with humic substances, as well as the effects of humic substance adsorption/precipitation on the binding of metalloid and trace elements. Future research directions include investigating the ability of Fe nano-particles to increase Fe bioavailability, improve carbon sequestration, reduce greenhouse gas emissions, and decrease the impact of persistent organic and inorganic pollutants.

Summary: This study investigates the changes in the coordination environment of potassium (K) in soil profiles using X-ray absorption spectroscopy (XAS) combined with wet chemical extractions. The results show that the Mehlich extraction can remove the bonding between K and the siloxane surfaces in the interlayer space of illite and illite-smectite, resulting in increased hydration of K. This phenomenon is more significant in coarser-textured soils.

Summary: This study investigated the distribution patterns and underlying mechanisms of cadmium (Cd) isotope fractionation within soil profiles around a lead-zinc mine in southwest China. The results revealed that mining activity was the main source of Cd, which led to vertical migration of Cd isotopes within the soil profiles. The Cd isotope fractionation was correlated with the content of free iron and manganese oxides in the soil, indicating their role in the migration of Cd isotopes. This study highlights the importance of considering Cd mobilization and transport in soil profiles when using isotope techniques to trace metal sources.

Summary: Interactions between mineral and organic carbon (OC) play a crucial role in stabilizing OC and reducing greenhouse gas emissions after permafrost thaw. However, changes in soil water pathways can affect the stability of these interactions by inducing dissolution and precipitation. This study used the radiogenic Sr isotope method to assess how dissolution and precipitation impact mineral OC interactions in thawed and unthawed layers. The results demonstrate the potential of this method to trace dissolution-precipitation processes in thawing permafrost.

Summary: This study investigated the influence of the association of poorly crystalline iron (hydr)-oxides with organic matter (OM) on iron and carbon cycles in soils and sediments, as well as their behaviors under sulfate-reducing conditions. The results showed that the effect of added OM on sulfidation of ferrihydrite-organic matter (Fh-OM) coprecipitates is dependent on the amount of loaded sulfide. The presence of OM inhibited mineral transformation, with microbiogenic EPS having a stronger inhibitory effect compared to synthetic EPS proxies.

Summary: This study investigates the speciation of particulate iron in buoyant hydrothermal plumes through observations and modeling, revealing a high diversity in solid-state chemistry and the need for a multi-modal analytical approach. Equilibrium modeling was found to work well for certain phases but poorly for others, leading to recommendations for future field expeditions to explore a variety of site conditions and for the development of kinetic models and expansion of thermodynamic databases to better reflect the composition of plumes.

Summary: Deep subsurface environments host diverse microbial communities facing unique challenges, with nutrient limitations likely facilitating diverse microbe-microbe interactions that drive biogeochemical cycling of major elements. Microbial communities in low temperature, chemically reduced brines at the Soudan Underground Mine State Park are dominated by Firmicute and Proteobacteria phyla, with metabolic reconstruction showing dominant carbon-fixation pathways and potential for cryptic sulfur cycling. Overall, metabolic flexibility is an important trait for microorganisms in deep isolated systems.

Summary: This study examines trends in intra-archipelago exchange in the Samoan archipelago, specifically the Manu'a group, using geochemical and limited technological analysis of a lithic assemblage. The results indicate the presence of material from multiple basalt sources, including sources outside the Manu'a group. The nonlocal material was used differently than local material, but there is no evidence to suggest differential distribution or control. This suggests decentralized exchange and the use of imported materials as common pool resources to support community resiliency and sustainability.

The degree of earthworm invasion and soil depth influenced the structures of microbiomes and the abundance of functional genes. In soils with minimal invasion, genes related to nitrification were more abundant, while in heavily invaded soils, genes related to denitrification and nitrogen fixation were more abundant.

Summary: Our meta-analysis reveals that the microbial diversity in the terrestrial deep subsurface is dominated by Betaproteobacteria, Gammaproteobacteria, and Firmicutes, suggesting their diverse metabolic strategies as the reasons. Furthermore, a common small consortium of prevalent Betaproteobacteria and Gammaproteobacteria operational taxonomic units was found across various locations, implying a core deep subsurface community that plays a significant role in colonizing and sustaining microbial habitats. In silico contamination-aware analysis of the deep subsurface-derived sequencing data emphasizes the importance of downstream methods to ensure the reliability of conclusions. Understanding microbial diversity and ecological dynamics in the deep terrestrial subsurface is crucial for comprehending the microbial contribution to global subsurface element and nutrient cycling.

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.

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.
