Summary: Dyed wastewater has a serious impact on living organisms and must be treated before being released into the environment. Metal organic frameworks (MOFs) have been proposed as the most effective method for dye wastewater removal due to their high adsorption capacity and adjustable pore diameter and surface morphology. This study aims to evaluate the effectiveness of different types of MOFs in dye separation from wastewater and includes the examination of adsorption isotherms, kinetics, and characterization studies. The desorption and reuse of MOFs are also considered.

Summary: Anionic hydrogen bonded frameworks were synthesized using di or tetra-amidinium hydrogen bond donor components and a charge mis-matched tecton. The presence of a cation in the framework channel is required due to the net negative charge on the framework skeletons. The organic cation initially incorporated in one of the frameworks was displaced by smaller inorganic cations or the cationic dye methylene blue, enabling effective and selective removal of the dye from 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.
