Summary: In this study, zeolite NaA was prepared from lithium leach residue (LLR) using the traditional hydrothermal synthesis method, and its adsorption performance on Pb2+ and Cd2+ in heavy metal wastewater was investigated. The results showed that zeolite NaA exhibited excellent adsorption properties for Pb2+ and Cd2+, and the adsorption process followed the Langmuir model and pseudo-second-order model. The adsorption mechanism was attributed to ion exchange and hydroxyl groups on the zeolite NaA surface.

Summary: The heavy metal ions present in industrial wastewater pose a significant threat to human health. To mitigate heavy metal ion pollution, it is crucial to explore an adsorbent that is low-cost, environmentally friendly, exhibits high adsorption capacity, and is easily recyclable. In this study, lignin sulfonate derived from corn stover was modified using a hydrothermal method, resulting in a porous structure that provides more internal adsorption sites for heavy metal ions. The modified lignosulfonate adsorbent efficiently removes heavy metals, particularly Cu2+ and Pb2+, from wastewater, with an adsorption capacity of 450.3 mg/g for Cu2+ and 475.4 mg/g for Pb2+. Additionally, at a concentration of 40 mg/L for Cu2+ and Pb2+, and using a dosage of 0.4 g/L of adsorbent, the adsorption equilibrium is achieved within 60 minutes. Furthermore, the adsorbent achieves removal rates of 83% for Pb, 72% for Cd, 87% for Cu, 36% for Zn, 25% for Mn, 95% for Cr, and 99% for Fe in wastewater within 2 hours. This research demonstrates the development of a practical adsorbent for the removal of heavy metals from real-world wastewater.

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.
