Summary: In this study, flotation experiment and analysis were conducted on the high-Ge low-rank coal from Wulantuga Coal Mine in Inner Mongolia, China. It was found that the cleaned coal had increased moisture content, decreased ash yield, and some elements were released into the water during flotation. The cleaned coal contained enriched elements in organics or fine-grained minerals, while other elements were weakly associated with organics or occurred in minerals. Therefore, alternative preparation methods are needed to remove difficult-to-remove elements.

Summary: The surface of Mercury is enriched in sulfur, and novel experiments suggest that the reaction of Mercury composition glasses with reduced S-rich gas forms sulfides, explaining the formation of hollows on Mercury. The BepiColombo mission will test this hypothesis.

Summary: The small Indian mongoose was found to produce reactive sulfur species (RSS) and monothiols that may be involved in detoxification of organomercury. The presence of CBS and CSE enzymes in mongoose organs suggests a detoxification mechanism similar to that in mice. Additionally, a low-toxic compound bismethylmercury sulfide was identified in the liver of this species, further indicating detoxification processes at work in response to high mercury levels in the body.

Summary: The presence of sulfides, either endogenous or exogenous, plays a key role in controlling mercury methylation. Sulfide concentration affects the methylation process and there is a positive correlation between sulfide concentrations and the production of methylmercury. These findings suggest that sulfides should be considered when studying the impact of Hg in natural environments.

Summary: It is a win-win strategy to prepare mercury sorbents from low-cost high-sulfur raw materials. In this work, a two-step preparation method is developed to prepare mercury sorbents from high organic sulfur coal. The first step is the co-pyrolysis/carbonization of Fe2O3 and coal, converting organic sulfur into FeSx. The second step is KOH activation, converting FeSx into various S species. The prepared sorbents show excellent mercury removal performance.

Summary: In this study, selenium and sulfur-modified montmorillonite materials were designed and synthesized to effectively reduce mercury levels in crops and avoid excessive selenium enrichment. The results showed that these materials significantly reduced mercury concentrations in water spinach and hybrid Pennisetum without causing excessive selenium bioaccumulation. This approach is easy to prepare, requires small amounts, and has high environmental and economic potentials.

Summary: This study investigates the sorptive behaviors of Hg(II) by sulfur-aged microplastics in anaerobic environments. The results show that the sulfur aging process greatly enhances the MP's sorption capacity of Hg(II). Thiol groups play a dominant role in enhancing the adsorption capacity of microplastics.

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: Sulfur-containing polymers, such as PST, loaded into PVDF/PMMA polymer matrix by electrospinning technology, showed enhanced adsorption of Cd(II), Cr(III), Ni(II), and Hg(II) ions under reduction stimulation. The adsorption of Hg(II) and Cd(II) ions onto the reduced membrane follows a pseudo-second-order kinetic model, indicating PST's potential for heavy metal ion removal from wastewater through a convenient and reusable adsorption process.

Summary: Mercury mining in southwest China may have started before the establishment of the Qin dynasty, around 2500 years ago, potentially motivated by climate changes and human industrial activities. Two major peaks of mercury deposition were observed in the past 10,000 years, coinciding with critical climate changes. This study highlights the significance of climate variability and local mercury mining in controlling global atmospheric mercury deposition during the Holocene.

Summary: This study proposed a novel chemoautotrophic elemental sulfur disproportionation (SD) process as an alternative to conventional biological sulfidogenic processes (BSPs) for the treatment of organic-deficit acid mine drainage (AMD). The SD process achieved a stable high-rate sulfide production without the need for exogenous organic substrates, and it effectively removed over 99% of the influent metals from AMD.

Summary: The unique spatial configuration and unsaturated-coordination nature of metal-sulfur clusters contribute to their remarkable chemical activity. In this study, we successfully constructed a Mn-Sn2S6 framework by manipulating the sulfur environment, which exhibited superior performance in removing gaseous elemental mercury and high resistance against SO2. The study provides important insights for environmental pollution control and cluster-based material design.

Summary: Chemical treatment of skeletal remains can reduce overall DNA quality and quantity but has no significant impact on stable isotope ratio analysis. Examination of treated and untreated human remains through histological and stable isotope analysis reveals that treated remains exhibit better preservation compared to untreated remains. Stable isotope ratio analysis is viable for both treated and untreated remains, regardless of their origin.

Summary: This paper presents the outcomes of a microcontextual geoarchaeological study conducted on earthen dwellings from the Early Iron Age village of Cerro de San Vicente. The study employed soil micromorphology, lipid biomarker analysis, XRD, and XRF analyses to investigate various aspects of the dwellings, including construction materials, site formation processes, and daily life practices. The results have shed light on the construction layers, floor use, maintenance, repaving, periods of abandonment and decay, and the presence of lipid biomarkers associated with dwelling functionality. The study significantly contributes to our understanding of ancient construction practices and the utilization of domestic spaces during the Early Iron Age.
