Summary: The disposal of pharmaceuticals and plastic waste produces contaminants of emerging concern (CECs) in landfill leachate. This study found that CECs, including pharmaceuticals and plasticizers, can persist in leachate many years after landfill closure. The transport of these compounds with landfill leachate is expected to continue as long as leachate is generated in the landfill.

Summary: This review paper provides a comprehensive overview of advanced oxidation processes (AOPs) based on ultrasound (US) for landfill leachate treatment. The review compares and summarizes existing treatment methods for leachate, with a focus on the degradation of emerging contaminants (ECs). It also introduces US-based AOPs in detail, including their mechanisms, influencing factors, energy consumption, optimization methods, and potential field-scale applications. In addition, the review discusses the advantages of dual-frequency US (DFUS) technology and proposes a theoretically feasible DFUS process for ECs treatment in leachate. Suggestions and prospects for future research on US technologies in landfill leachate treatment are also provided.

Summary: The study evaluates the efficacy of four different garbage enzymes prepared from fruit peels (pineapple, banana, orange, and lemon) in removing soluble chemical oxygen demand (sCOD) from landfill leachate at two temperatures (room temperature and higher temperature). The results showed that orange (10%) and lemon (15%) garbage enzymes had the highest sCOD reduction at room temperature. The study demonstrated that the garbage enzyme could increase the bioavailability of organics in leachate.

Summary: Humic acid-based sulfur-chlorine-doped carbon quantum dots (L-CQDs) were synthesized using landfill leachate concentrate (LLC) as a carbon source via a polyethylene glycol (PEG)-assisted hydrothermal technique. The prepared L-CQDs showed excellent hydrophilicity and dispersibility due to the presence of oxygen-containing functional groups and small average particle size. The L-CQDs were then used to prepare fluorescent nanoprobes for the selective detection of Pd2+ ions, exhibiting high selectivity, water solubility, and stability. This work provides a simple and efficient method for Pd2+ detection and promotes the resource utilization of LLC.

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.
