Summary: The accuracy of mercury dendrochemistry is questioned due to knowledge gaps in Hg translocation in tree-ring. Results show that Hg concentrations in tree-ring do not accurately reconstruct the temporal trend of Hg production. The isotopic profiles of Hg in tree-ring exhibit variability and can be used to reconstruct atmospheric Hg pollution levels and emission source shifts.

Summary: The decline of shark populations in the world ocean has unpredictable effects on ecosystem structure and function, necessitating new ecological information for a better understanding of the role of sharks in their habitats. Research has found that many shark species primarily forage in the mesopelagic area, but the extent to which different pelagic sharks rely on this habitat has been overlooked. By using mercury stable isotopes in the muscle of pelagic sharks, it is possible to reveal their food partitioning and the relationship between foraging depth and resource competition.

Summary: This paper reviews the progress in using mercury isotopes to understand the internal processes of mercury in biota. Mercury stable isotopes are a powerful tool for assessing mercury sources and biogeochemical processes. Understanding the internal mechanisms leading to mercury isotope change is crucial. There is still uncertainty in the understanding of the internal processes leading to mercury isotope fractionation.

Summary: The study in French Guiana aimed to investigate the impact of gold-mining activities on mercury concentrations and isotopic signatures in freshwater fish consumed by local residents. Analysis of Hg concentrations and isotopic ratios in fish muscles revealed differences in biogeochemical processes between fish from impacted and pristine areas, indicating potential influences of suspended particles on mercury concentrations. The study also highlighted the potential of Hg isotopes in fish as complementary tracers to understand the sources and processes of mercury accumulation in aquatic ecosystems.

Summary: This study investigates the concentration and isotopic signatures of mercury (Hg) in the surface soil of the Qinghai-Tibetan Plateau (QTP). The spatial distribution and source contribution of Hg in the surface soil, as well as factors influencing Hg accumulation, are comprehensively studied. Results show that vegetation mediated atmospheric Hg0 deposition is the dominant source of Hg in the surface soil, followed by geogenic sources and atmospheric Hg2+ inputs.

Summary: Mercury (Hg) reduction during anoxygenic photosynthesis and fermentation in the model anaerobe Heliobacterium modesticaldum Ice1 was explored using Hg stable isotope fractionation. The study found that cells preferentially reduce lighter Hg isotopes in both metabolisms, leading to mass-dependent fractionation, but mass-independent fractionation induced by UV-visible light was absent. Factors affecting Hg recruitment, accessibility, and availability pathways alongside metabolic redox reactions were shown to influence fractionation during these processes. The study suggests that similar controls likely underpin diverse microbe-mediated Hg transformations affecting Hg's fate in oxic and anoxic habitats.

Summary: In this study, the utility of leopard seal whiskers as a biomonitoring tool for tracking contaminants and monitoring the health of Antarctic flora and fauna was examined. The analysis of leopard seal whiskers revealed variability in non-essential trace elements over time that could be partly explained by changes indict. The levels of mercury (Hg) in the whiskers were not high enough to indicate high risk of Hg toxicity, but the maximum Hg concentrations observed were higher than those measured two decades ago. The study also suggested that selenium (Se) may detoxify the Hg burden in leopard seals.

The results show different isotopic compositions for different types of granites, suggesting significant isotopic fractionation during magmatic processes. By combining with previously published data, the Hg abundance and isotopic composition of the upper continental crust are estimated to be higher than that of the primitive mantle.

The study found that estuarine mixing processes caused the removal of colloidal REE through salt-induced flocculation, while REE desorption from particles occurred with increasing salinity. The study also observed anomalies in Gd and Sm concentrations, which indicated significant impacts from human activities such as wastewater treatment plants and industrial sources.

Summary: This study developed a micro/nanoplastics model based on the near-infrared-AIE technique, which allows for reliable visualization, tracking, and quantification of MNPs in vivo. The results showed that MNPs were mainly accumulated in the fish gut, with a heterogeneous distribution. Microplastics tended to accumulate more in the fore and mid areas of the gut compared with nanoplastics. Additionally, MNPs accumulated slowly during the initial exposure followed by rapid and sustained accumulation in the gut.

Summary: By re-sequencing and genome sequencing analysis of Eleutheronema tetradactylum in two independent environmental axes in China and Thailand, the genetic characteristics and adaptive differences of this species were revealed. The low level of genomic diversity explained the decreased adaptive potential in the wild environment. Selective sweeps at genes related to thermal and salinity adaptation were discovered, which might be the driving factors of the geographical divergence. Strong selection in artificial breeding was also observed in genes related to fatty acids and immunity.

Summary: This study used multi-element signatures of fish fin rays to differentiate wild-caught and pond-cultured Fourfinger threadfin species in the southern coast of China. The results showed significant differences in the multi-element compositions between wild and cultured fish, and the LDA and RF models accurately classified them. However, the fin ray signatures could not differentiate different wild groups. This strategy provides a promising method to prevent mislabeling of Fourfinger threadfin. Rating: 8/10.

Summary: In this study, a human physiologically based pharmacokinetic (PBPK) model of diethyl phthalate (DEP) was developed to assess its toxicity. 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.

It was found that increasing the application of thiencarbazone-methyl center dot isoxaflutole resulted in increased stress on soil bacterial community structure and diversity. Increasing soil pH was recognized as a key factor in improving the diversity and structure of soil microflora. Supplemental use of nitrapyrin or modified attapulgite can increase soil pH and improve bacterial diversity.
