Summary: Understanding the adsorption behavior of antibiotics on minerals is crucial for determining their fate in soils and waters. This study used molecular dynamics simulations to investigate the adsorption of two common antibiotics, tetracycline and sulfathiazole, on montmorillonite. The results revealed the molecular orientation and conformation of the antibiotics during the adsorption process, providing insights into the complexity of antibiotics adsorption to soil and their environmental transport and fate.

Summary: An increase in exogenous cations tends to promote the release of intrinsic potassium in illite. Intrinsic potassium generally dominates the competition with exogenous cations. The stability of adsorbed mixed cations decreases with increasing concentration, and exogenous cations have diverse effects on intrinsic potassium.

Summary: Polydopamine-modified montmorillonite/chitosan (PDA-mMMT/CS) aerogels with abundant functional groups and large specific surface area were synthesized through a green and convenient synthesis strategy. These aerogels exhibited excellent adsorption capacity for Cu(II) and Pb(II) in aqueous solution, mainly through chelation adsorption and ion exchange mechanisms.

Summary: In this study, DTPMP-modified hydroxyapatite was used to remove Pb2+, and its adsorption capacity was 10.4 times higher than that of commercial nanohydroxyapatite. Molecular dynamics simulations showed that the organic-phosphonic group of DTPMP had a stronger complex effect with calcium ions or lead ions, which improved the removal effect of DTPMP-doped hydroxyapatite composites for Pb2+ contaminants.

Summary: Soil heavy metal pollution is a globally important ecological and environmental problem. Previous studies have explored the pollution sources, adsorption capacity, and distribution of heavy metals, as well as the phyto-uptake and ecotoxicity of heavy metals. However, there is a lack of systematic reviews on heavy metal pollution in soil-plant systems in the past decade. Understanding the mechanisms of interaction between heavy metals and solid soil components is crucial for effectively controlling and remediating heavy metal pollution.

Summary: In typical aqueous systems, multiple ion species are co-solvated, and these ions at the water-air interface can have significant impacts on chemical reactivity, aerosol formation, climate, and water odor. Through sum-frequency generation spectroscopy, researchers have quantified the relative surface activity of two co-solvated ions and found that hydrophobic ions tend to be speciated to the water interface due to the presence of hydrophilic ions. The speciation of ions at electrolyte solution interfaces is determined by the solvation energy difference between the ions and the intrinsic surface propensity of ions.

Summary: The interactions between water and ions within droplets are critical in the chemical reactivity of atmospheric and man-made aerosols. Computational evidence shows that in supercooled aqueous nanodroplets, a lower density core of tetrahedrally coordinated water expels ions to the denser subsurface. At room temperature, the radial distribution in the droplet core varies depending on the ion's nature.

Summary: Classical molecular dynamics simulations were performed to compare water structures with ab initio molecular dynamics simulations. Good agreement was found between the two approaches at the same length and time scales. However, longer trajectories simulated with classical molecular dynamics led to the formation of different, more stable water structures, which were validated with ab initio calculations. This suggests the usefulness and advantage of classical molecular dynamics simulations for sampling more realistic time and length scales in simulations of metal-aqueous solution interfaces.

Summary: The study investigates the effect of component proportional feature on the microscopic adhesion of asphalt-mineral aggregate interface in cold areas. Results showed that the microadhesion and diffusion rate of asphalt on mineral surface decrease after short-term aging, but the decay trend reduces after long-term aging. Saturate and aromatic fractions have a dominant wetting effect on the mineral surface in the microadhesion effect on the asphalt-mineral aggregate interface in cold areas.

Summary: A novel heavy metal remediation material (Mt@ZrP) was successfully prepared using montmorillonite to induce the structural rearrangement of zirconium phosphate (ZrP), achieving rapid remediation of contaminated water and soil bodies. Mt.@ZrP exhibited a distinct adsorption mode with internal spherical coordination, leading to a shorter adsorption equilibrium time (23 min) and higher adsorption capacity (275.6 mg/g-ZrP) for Cd removal compared to bare ZrP. In soil remediation, Mt.@ZrP demonstrated a faster Cd removal rate than bare ZrP.

Summary: The development of low-cost, high-efficiency, and environmentally friendly adsorbents for the removal of antibiotics and heavy metal ions in water is urgently needed. Phosphorylated alkali lignin (PAL) microparticles were successfully fabricated via a simple one-pot method, showing great potential in adsorption of pollutants such as levofloxacin hydrochloride (LH) and lead ions (Pb(II)). The results demonstrated that PAL had a strong ability to remove complex pollutants, with high adsorption capacity and removal percentage for various contaminants in water.

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.

Summary: Ocean depth affects microbial diversity, composition, and co-occurrence patterns of microplastic microbial communities. 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.
