Summary: Mercury pollution is a global issue that depends on its chemical form. Redox reactions in water greatly affect the release and transformation of mercury, making it crucial to study these reactions for predicting the transport and fate of mercury in aquatic environments. This review summarizes the current knowledge on specific redox reactions of mercury in natural waters, including rate constants, influencing factors, and mechanisms. It also highlights the significant role of natural organic matter in the reduction and oxidation of mercury, as well as the identified photooxidation pathways.

Summary: This study focused on the design of amine-functionalized alumina nanofibers for effective removal of lead (II) and mercury (II) ions from aqueous solutions. The nanofibers demonstrated high adsorption capacities, removing 98% of Hg2+ ions and 90% of Pb2+ ions at specific concentrations. The optimal pH conditions for ion adsorption were determined to be 6, and the nanofibers showed selective adsorption of mercury (II) and lead (II) ions in the presence of other metal ions. Desorption tests confirmed the stability of the heavy metals on the nanofibers.

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.
