Summary: The nonstationary nature of water and oxygen content in the vadose zone determines various biogeochemical reactions regarding arsenic (As) therein, which affects the groundwater vulnerability to As contamination at a site. In the present study, we evaluated the effect of soil organic matter (OM) on the behavior of As using specifically designed soil columns that simulated the vadose zone. OM was found to exhibit variable effects, either inhibiting or accelerating the mobilization of As, depending on bulk density.

Summary: This study found that bacterial transport and retention depend on bacterial and soil surface properties, especially hydrophobicity. Wettable and water-repellent sand columns were used to explore the transport of hydrophilic Escherichia coli (E. coli) and hydrophobic Rhodococcus erythropolis (R. erythropolis) under dry and water-saturated conditions. The dominant retention mechanisms switched between attachment and straining depending on the bacteria and the wetting condition. This research highlights the importance of considering the interaction between bacterial hydrophobicity and soil properties in predicting bacterial transport and retention.

Summary: Rice is a staple food globally, but traditional cultivation methods lead to arsenic accumulation in rice grains. Alternate wetting and drying (AWD) is advocated for reduced arsenic levels, water savings, and decreased methane emissions. However, the effects of AWD on micronutrient element concentrations in rice grains are unclear. This study found that AWD tends to increase cationic element concentrations while decreasing oxyanionic element concentrations. The decrease in total arsenic in rice grains under AWD is mainly driven by changes in dimethylarsinic concentrations. The effects of AWD on grain composition were more significant in 2017 compared to 2018, possibly due to differences in dry-down timing during rice development. Additionally, interannual variability in grain elemental composition was observed in continuously-flooded fields, potentially influenced by warmer temperatures in 2018.

Summary: In this large-scale field study, the input and occurrence of water and nitrogen species in the vadose zone were evaluated, as well as the potential transport of nitrate, ammonium, arsenic, and uranium. The study found that irrigation practices significantly affected the concentrations of nitrogen species in the sediment, and the distribution of arsenic and uranium correlated with the input of nitrogen and water.

Summary: This study conducted laboratory experiments on sandy columns and found that hydrological and biogeochemical controls play essential roles in regulating nitrogen dynamics during different stages of wetting-drying cycles in intermittent managed aquifer recharge (MAR) systems. Intermittent MAR functioned as a nitrogen sink while providing a carbon source for nitrogen transformations, but it occasionally became a source of nitrogen under intense flushes of preferential flow. A saturated zone mediated nitrogen dynamics by creating oxygen-limited conditions for denitrification and buffering the effects of preferential flow.

Summary: Global warming-induced sea level rise poses a threat to maritime structures. The durability of cementitious materials such as OPC, PBC, and AAM in seawater environment is still not clear. This study reviews and compares the chemical interactions and properties of these materials in seawater. It also evaluates their performance, including compressive strength, mass change, porosity, water absorption, and chloride permeability in the face of seawater deterioration mechanisms and environmental factors. Suggestions for further research to improve durability in seawater attack are provided.

Summary: In this paper, a laboratory study was conducted to investigate the changing soil properties under complex physicochemical interactions. Triaxial tests were performed with three types of pore water, and the deterioration of soil strength, change in soil micro-structure and mineral composition were observed. The findings suggest that acidic underground water significantly damages the soil microstructure and weakens the shear strength compared to normal underground water, while distilled water causes minimal disaggregation.

Summary: Wetting-drying cycles were found to enhance the bioavailability of Cu in paddy soil treated with CuO nanoparticles, preventing the aging process of Cu and transforming oxidizable Cu to different forms. Additionally, wetting-drying cycles significantly affected the transformation of dissolved organic matter and sulfate, as well as the changes in iron content. Therefore, natural precipitation and artificial irrigation play a crucial role in determining the environmental risks of metal-based nanoparticles.

Summary: This study assessed whether a US model could accurately describe the effects of increasing atmospheric CO2 on soil moisture dynamics in temperate grasslands. The model was found to adequately represent the impacts of vegetation and atmospheric CO2 concentration on soil moisture dynamics. The results showed that increasing atmospheric CO2 resulted in reduced soil moisture, and while the model performed well in broadly explaining soil moisture dynamics, further scrutiny is needed for point-specific simulations.

Summary: This study reveals that chronic exposure to PM induces chronic inflammation and development of COPD by dysregulating NAD+ metabolism and subsequent SIRT1 deficiency in pulmonary macrophages. Activation of SIRT1 by resveratrol effectively mitigates PM-induced inflammation and COPD development. Targeting metabolic and epigenetic reprogramming in macrophages induced by PM is a promising strategy for COPD treatment.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.

Deterministic processes dominate the assembly of mesopelagic plastisphere microbial communities, while stochastic processes shape the assembly of bathypelagic microbial communities. The relationships between microorganisms in the mesopelagic layer are more complex and stable, with Proteobacteria and Actinobacteriota playing important roles.
