Summary: Concerns over heavy metals in wastewater and their impact on the environment and human health can be addressed through adsorption technology. This study developed efficient and cost-effective adsorbents, specifically chitosan-grafted polyacrylonitrile/ZnO, for the treatment of water contaminated with heavy metals. Various tests confirmed the morphological and structural properties of the materials, and the adsorption behavior of Fe(II) ions was studied. The adsorption process followed the Langmuir model and pseudo-second-order kinetics, suggesting a monolayer formation of Fe(II) over the adsorbent surface.

Summary: The presence of nanoparticles in drinking water raises concerns about their potential risks to human health and the efficacy of water treatment plants in removing them. This study examines the efficiency of granular activated carbon (GAC) in removing CeO2 nanoparticles. The results show that GAC has a good affinity for nanoparticles, with higher adsorption capacity and removal efficiency in lake water compared to ultrapure water. The adsorption mechanism is mainly controlled by electrostatic attractions, and mass transfer processes play a role in the removal of nanoparticles in lake water.

Summary: This paper presents a brief account of the theory of adsorption from solution developed by Ostwald and de Izaguirre in 1922 on its first centenary. It provides an overview of the theory and its validation using animal-derived carbons, and assesses its impact on the field of adsorption by carbons. The main outcomes of the theory are the classification of adsorption isotherms and an equation describing the adsorption of liquid mixtures by solids, which is still widely used today.

Summary: This study investigated the characteristics of activated carbon from cashew nut shell produced by potassium hydroxide activation at 600 degrees C in an N2 atmosphere. The sample obtained with a CNS/KOH ratio of 1:1 had the highest surface area compared to other ratio samples. The effects of contact time, pH, adsorbent dose, and initial dye concentration on brilliant green (BG) removal efficiency were studied using the CNS/KOH ratio of 1:1 sample as the adsorbent. The Langmuir isotherm provided the best fit for the experimental equilibrium data, with a maximum BG adsorption capacity of 243.90 mg/g.

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.
