Summary: Rice consumption is a major pathway for human methylmercury exposure in inland China, especially in mercury contaminated regions. However, high levels of methylmercury are still found in rice, calling for reconsideration of the bioavailability of mercury species in paddy soils. Incubation experiments showed that different Hg(II) species have varying impacts on mercury methylation at different mercury concentrations, emphasizing the importance of considering site-specific characteristics and the nature of mercury substrates for determining net methylmercury production.

Summary: Biochar has been receiving increased research attention for its effectiveness in mitigating mercury risks in agricultural soils. However, there is a lack of consensus on the impact of pristine biochar on methylmercury production, availability, and accumulation in paddy rice-soil system. A meta-analysis was conducted with 189 observations, revealing that biochar application could significantly increase methylmercury production in paddy soil, while decreasing its availability. Furthermore, biochar application inhibited methylmercury accumulation in paddy rice.

Summary: The presence or absence of rice plants was found to have different effects on the concentration of MeHg in rice paddy soil, with methylation being the dominant control in non-vegetated soil and demethylation being the dominant control in vegetated soil. The presence of rice plants reduced MeHg production capacity and resulted in lower variance of MeHg concentrations in the soil.

Summary: The study found that both methylation and demethylation of mercury occurred in fish exposed to organic or inorganic mercury in the diet, with demethylation being faster. Intestinal microbiota play a predominant role in mercury biotransformation, significantly influencing mercury speciation and distribution.

Summary: The cycling of mercury in remote alpine lakes, which are sensitive ecosystems, involves methylation and bio-magnification pathways. A study conducted in the Western/Central Pyrenees analyzed the speciation and variations of mercury in pristine lakes at high altitudes. The findings suggest that environmental changes, such as global warming and potential eutrophication, can significantly affect the turnover of mercury and the burden of methylmercury in these remote ecosystems.

Summary: Methylation and demethylation processes play a crucial role in controlling the concentration of monomethylmercury (MeHg) in natural environments. The formation of refractory MeHg pools in sediments and soils, which are not readily available for demethylation, is an important factor that contributes to the overall pool of MeHg.

Summary: Arsenic biomethylation is a crucial part of the biogeochemical cycle, leading to the production of methylarsenite (MAs(III)), which some microbes use as an antibiotic to gain a competitive edge. While some microbes have evolved detoxification mechanisms to demethylate MAs(III), the process under anoxic conditions remains unclear. This study found that nitrate addition in flooded paddy soil enhanced MAs(III) demethylation and identified a novel mechanism involving C-As lyase gene (BcarsI) in Bacillus sp. CZDM1 for MAs(III) demethylation under anoxic nitrate-reducing conditions.

Summary: Accurately measuring the concentration of methylmercury (MeHg) is crucial for mercury (Hg) research. In this study, we compared two widely used methods for extracting MeHg from paddy soils, namely acid extraction and alkaline extraction. Through evaluation and quantification, we found that alkaline extraction is the optimal choice for paddy soils, with minimal MeHg artifact and consistently high extraction efficiency compared to acid extraction. Our findings emphasize the importance of suitable pre-treatment and quality controls in measuring MeHg concentrations.

Summary: The study found that biochar amendment to paddy soils can increase the migration of mercury and the formation of methylmercury. Additionally, biochar alters the composition of soil organic matter, which is positively correlated with methylmercury concentration. However, there are environmental risks associated with biochar application to paddy soils under dynamic redox conditions.

Summary: A systematic analysis was conducted on 159 coal samples from different regions, periods, and ranks across China, including antimony (Sb) isotopic composition, trace element contents, and total sulfur content (TS). The study discusses the origin of Sb in coal from different regions in China, highlighting the influence of hydrothermal fluid, leachate, terrigenous materials, and inorganic minerals on Sb enrichment. The establishment of the Sb isotopic fingerprint for coal is essential for researching Sb isotope fractionation and tracing Sb release and transport in the supergene eco-environment.

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: This study investigates the adsorption mechanisms of antimony (Sb) on iron (oxyhydr)oxides and finds that inner-sphere complexation occurs independently of pH and surface coverage. Lighter Sb isotopes are preferentially enriched on Fe (oxyhydr)oxides due to isotopic equilibrium fractionation. The results provide insights into the Sb adsorption mechanism by Fe (oxyhydr)oxides and clarify the Sb isotope fractionation mechanism, which is essential for future applications of Sb isotopes as tracers.

A study found a strong overlap between Lake Gokyo and Indian anthropogenic sources, indicating the source of mercury from South Asia. The findings suggest that transboundary atmospheric transport can transport mercury from South Asia northwards to at least the Tanglha Mountains in the northern Himalaya-Tibet.

Summary: Cardamine violifolia, a selenium hyperaccumulator, can accumulate mercury in its roots and aboveground parts at concentrations up to 6000 μg/g. The bioaccumulation factors of Hg reached 1.8-223, and the translocation factor reached 1.5. The study revealed a positive correlation between Hg concentrations in plant tissues and soil. The findings provide insights into the mechanisms of Hg hyperaccumulation in C. violifolia and suggest its potential use in remediation of Hg-contaminated farmlands.

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.

The model considers the distribution and metabolism of DEP and its active metabolite monoethyl phthalate (MEP) in different tissue compartments. Sensitivity analysis and Bayesian Markov chain Monte Carlo (MCMC) simulations were performed to evaluate the uncertainty and variability of the model parameters. The results suggest that dermal absorption is an important route of exposure to DEP in the environment.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.
