Summary: The study investigated the long-term vertical and horizontal mobility of mercury in soils of an historically contaminated agricultural area in Italy. The research found variations in mercury concentrations with depth and spatially within the same field, influenced by factors such as mercury loading, soil properties, and the presence of different plant species. Additionally, a greenhouse experiment demonstrated that certain plant species can affect the mobility and potential bioavailability of mercury in soils.

Summary: The first assessment of atmospheric pollution by mercury in the Ossola Valley industrial area near the Toce River revealed high contamination levels due to a chlor-alkali plant. Measurements of gaseous elemental Hg levels and analysis of Hg concentration in lichen samples showed a north-south gradient of mercury accumulation, with the southern area more exposed to Hg dispersion from the industrial site. Long-term studies on Hg emission and dispersion in the Ossola Valley are necessary to assess potential impacts on ecosystems and human health.

Summary: Traditional disposal methods for waste salt are harmful to the environment, while resource utilization of waste salt is beneficial. In this study, waste salt from the glyphosate industry was treated using photoelectrocatalysis and utilized as a raw material for chlor-alkali electrolysis. The photoelectrocatalytic treatment effectively removed organic impurities from the waste salt, making it suitable for use in chlor-alkali electrolysis.

Summary: The study found that using carbon foam impregnated with goethite can significantly reduce the availability of Hg in soils, and the proportion of Hg associated with humic acids determines the mobility and availability of Hg. The presence of acidic groups on the surface of the foam can enhance the binding of metal cations, improving Fe immobilization.

Summary: This study aimed to determine the mass fractions of inorganic mercury and methyl mercury in soil certified reference material EnvCRM 03 with a complex matrix composition. The contents of inorganic mercury and methyl mercury were established using species-specific isotope dilution inductively coupled plasma mass spectrometry combined with on-line high-performance liquid chromatography or classical off-line chromatography. Different extraction protocols were verified, and both sequential extraction and one-step extraction showed promising results. The developed analytical methodologies were found to be equally sensitive and suitable for speciation analysis of mercury species in complex matrix samples.

The chlor-alkali plant in Pavlodar, Kazakhstan has historically contributed to mercury contamination, with elevated levels found in soil, water, air, and biota. While the current study suggests acceptable risks from exposure to mercury contamination in the region, further assessment is needed for worker exposure scenarios and consumption of contaminated fish from Lake Balkyldak.

Summary: Mine waste in historical mercury mining areas continuously emits mercury into the local environment, including aquatic ecosystems. This study used data on mercury concentration, speciation, and isotopes to trace mercury migration from the mine waste and determine its contribution to mercury pollution. The findings revealed that rainfall can increase mercury concentrations in river water and influence the partitioning and transport of mercury in karst fissure zones. Despite remediation efforts, the treated mine waste remains a significant source of mercury pollution in local aquatic ecosystems.

Summary: Rice paddies provide optimal conditions for methylmercury (MeHg) production, with paddy soil being the main source of MeHg in rice grains. The role of dissolved organic matter (DOM) in controlling MeHg production in rice paddy systems is not well understood. This study investigated the variations in soil DOM and the influence of DOM concentration and optical characteristics on MeHg production in paddy soils from different cultivation sites in China. The results showed that MeHg production is correlated with the consumption of lower molecular weight DOM and the humic components of DOM play a significant role in MeHg variability in paddy soil. The study also revealed that allochthonous DOM limits Hg bioavailability in contaminated soils and autochthonous DOM enhances MeHg production in uncontaminated soils.

Summary: The colonization and expansion of land plants happened earlier than previously thought, during the Ordovician-Silurian transition, based on analysis of Hg isotopes in marine sediments from South China. The negative excursions in Delta Hg-199 and Delta Hg-200 found in these sediments indicate increased terrestrial contribution of Hg due to the rapid expansion of vascular plants. This expansion coincided with rising atmospheric oxygen concentrations and global cooling.

Summary: Litterfall, including needles/leaves, contributes to over 50% of total mercury deposition in forest ecosystems. A study in a subalpine forest in Switzerland found that lichens and fine litter, along with needle litter, have a significant contribution to annual mercury deposition. The seasonal pattern of litterfall and rainfall suggests that this finding could be generally valid.

Summary: This study investigates the role of vegetation and soil in regulating atmospheric Hg0 in a forest in Switzerland. The results show that foliage acts as a net sink for Hg-0 and preferentially absorbs light Hg isotopes. The soil mostly serves as a net source of atmospheric Hg0, with higher emissions from moss-covered soils. The study highlights the importance of soil in influencing atmospheric Hg-0 isotope signatures.

Summary: Understanding the complexation of mercury (Hg) with soil organic matter is crucial for assessing Hg accumulation and sequestration in forest ecosystems. Separating soil organic matter into particulate organic matter (POM) and mineral-associated organic matter (MAOM) can provide insights into Hg dynamics and cycling. The study found that atmospheric deposition is the main source of Hg in both POM and MAOM, with higher concentrations of Hg in MAOM compared to POM. The accumulation and sequestration of Hg in organic soil vary with vegetation succession, and the isotopic signatures of Hg are influenced by source mixing and sequestration processes.

Summary: The effectiveness of reducing environmental mercury levels by controlling anthropogenic emissions depends on the magnitude of re-emissions from the land and ocean. Recent advances in atmospheric mercury chemistry, vegetation uptake, seawater mercury sources, and riverine discharges challenge our understanding of the global mercury cycle. A new coupled atmosphere-land-ocean model suggests potentially higher atmospheric mercury emissions and emphasizes the need for more aggressive emission control to decrease mercury levels.

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.

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.
