Summary: The study proved the effectiveness of an integrated strategy combining pretreatment with microbial electrolysis-assisted anaerobic digestion system for sludge lysate treatment and resource recovery. The pretreatment enhanced the biodegradation and bio-transformation of organic compounds, while membrane separation improved methane yield and purity, as well as protein recovery. This strategy shows potential for widespread adoption in wastewater treatment plants for sludge lysate treatment and sustainable resource recovery.

Summary: Stormwater runoff is a significant source of heavy metals, and this study found that non-hazardous aluminum-based drinking water treatment residuals can effectively remove heavy metals from stormwater runoff. The use of organic materials and a low-energy process to generate granulated sorbents can overcome the low permeability issue.

Summary: In this study, an integrated anion exchange resin (AER) and electrochemical oxidation (ECO) treatment train was used to remove and destroy four structurally different perfluoroalkyl ether carboxylic acids (PFECAs). The results showed that flow-through columns packed with PFAS-selective AERs were highly effective for the removal of PFECAs, and the affinity of PFECAs was strongly correlated with their hydrophobic features. The regeneration of spent resin columns required a high percentage of organic cosolvent for achieving PFECA release, and the regeneration efficiency was higher for a macroporous resin than a gel-type resin. The treatment of spent regenerants resulted in high removal of methanol and conversion of PFECAs, with a significant recovery of organic fluorine as inorganic fluoride. Trifluoroacetic acid (TFA), perfluoropropionic acid (PFPrA), and perfluoro-2-methoxyacetic acid (PFMOAA) were identified as transformation products (TPs), and degradation schemes and reaction pathways for the four PFECAs were proposed. Dissolved organic matter (DOM) inhibited the uptake, regeneration, and oxidation of PFECAs, suggesting the need for pretreatment steps targeting DOM removal to enhance the treatment efficiency of the system.

Summary: The high use of disposable face masks due to COVID-19 has led to a global waste generation of 4.68-6.24 million tons per year from personal protective equipment. Disposable face masks, primarily composed of polypropylene (PP), are disposed of in landfills despite the high market value of PP. This study presents a solvent-targeted recovery and precipitation (STRAP) method that achieves 90% recovery of high-quality PP from face masks. N,N-Dimethylacetamide effectively removes color from the recovered PP, resulting in clear high-purity PP with similar thermochemical properties and color as virgin PP resin. Techno-economic analysis indicates that economically viable high-purity PP recovery can be achieved at a scale of 5000 tons per year or higher.

Summary: Solar-driven interfacial evaporation has been explored as a new approach for energy desalination. However, its potential for treating high-salinity organic wastewater, such as textile wastewater, has not been investigated. In this study, activated carbon fiber cloth (ACFC) was used to treat textile wastewater, achieving a high evaporation rate and effective separation of salt and organic dye. The study also demonstrated the potential for recovering a significant amount of salt, with a recovery rate of up to 89.6%. The research suggests the possibility of zero-liquid discharge technologies for textile wastewater treatment.

Summary: The study demonstrates that oxide modification greatly enhances the efficiency of aluminum powder for removing organic dyes, especially for methyl blue. LC/MS spectrum analysis reveals that dye molecules are broken down into small biodegradable organic molecules after reacting with OM-Al. Therefore, oxide modification activates aluminum powder for the removal of organic dyes.

Summary: With the increasing demand for industrial dyes, water conditions have deteriorated, leading to increased attention on the removal of environmentally hazardous pollutants from wastewaters through photocatalytic degradation. This study synthesized three mesoporous nanophases of BiFeVOx.y as visible light photocatalysts and evaluated their photocatalytic activities in degrading organic dyes. The results showed that the synthesis methods and doping strategy played important roles in improving the structure and surface properties of the nanophases, enhancing their adsorption and photocatalytic efficiencies.

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.
