Summary: Wetlands are important areas for studying mercury (Hg) biogeochemistry and have attracted global attention. A literature analysis of 15,813 publications on Hg in wetlands was conducted, revealing the changing focus of research over time. The research priorities for future studies include understanding the factors controlling methylmercury (MeHg) production, demethylation processes, bioaccumulation, and the role of wetlands in Hg circulation.

Summary: Mercury contamination in the Florida Everglades has been a persistent concern. This study examined mercury and methylmercury dynamics in different media and found strong linkages between air, water, and biota in the system. Changes in hydrology and climate were the main drivers of temporal patterns across different matrices. Unlike other regions, there was no evidence of a decline in atmospheric mercury deposition in this region. The study also identified geographic regions susceptible to higher methylmercury bioaccumulation, particularly in the Shark River Slough and Coastal areas. Improved water quality and flow rates, two key targets of the restoration program, are expected to reduce methylmercury production and exposure.

Summary: This study investigated the potential for mercury (Hg) methylation in two different aquatic systems. One system, Fourmile Creek (FMC), had a history of Hg pollution from groundwater, while the other, the H02 constructed wetland, only received atmospheric Hg deposition. The study found that FMC had a stronger Hg methylation potential and higher Hg bioavailability compared to the H02 wetland, which was attributed to differences in microbial communities. This study highlights the importance of long-term monitoring and sustainable ecological modifications for Hg-contaminated sites.

Summary: The South River in Waynesboro, Virginia is contaminated with mercury due to historical releases from an industrial facility. Two sampling events were conducted in 2015 to assess mercury concentrations in the bank interstitial waters during base flows and after flooding events. The results showed higher mercury concentrations during bank drainage compared to base flow conditions. Laboratory experiments using South River sediments revealed that drainage cycles can result in high mercury leachate from contaminated sediment. A remedial approach involving sediment removal and the placement of biochar and an armoring layer successfully decreased mercury concentrations.

Summary: This study investigated the distribution and bioavailability of heavy metals in sediments along two transects from the Yangtze River to the East China Sea continental shelf. Heavy metals were mainly found in fine-grained sediments enriched with organic matter. The turbidity maximum zone had the highest metal concentrations, especially Cd, indicating pollution. The non-residual fractions of Cu, Zn, and Pb were higher in the turbidity maximum zone and negatively correlated with bottom water salinity. DGT-labile metals were positively correlated with the acid-soluble metal fraction and negatively correlated with salinity, except for Co.

Summary: This study investigated the deposition and accumulation of mercury in a stream ecosystem. The results showed a correlation between labile mercury in porewater and bioaccumulative mercury in biota. The study found that surface sediment had higher mercury concentrations, and most of the sediment mercury existed in non-labile forms. Additionally, sulfate levels influenced mercury methylation and methyl-mercury production in the sediment. Methyl-mercury concentrations in the aquatic food web increased with trophic levels.

Summary: Research shows that after four years of operating the line diffuser hypolimnetic oxygenation systems (HOSs) in Almaden, Calero, Guadalupe, and Stevens Creek reservoirs, there were significant reductions in MeHg concentrations in bottom waters and declining trends in fish tissue Hg concentrations. However, MeHg concentrations in surface waters remained unchanged or increased, which could be due to enhanced mixing between surface and bottom waters resulting from oxygenation, or continued Hg methylation in the oxic water column and littoral sediments.

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.
