Summary: The study conducted in an urban wastewater treatment plant in Southeast Spain revealed that microfibers were the most common form of microplastics, and tertiary treatments can effectively discriminate between different forms. The research also indicated a significant daily emission of microplastics into the environment, highlighting the need for source control and specific microplastic-targeted treatment.

Summary: This study investigated the effectiveness of sequential or simultaneous UV and chlorine disinfection in inactivating disinfectant resistant Staphylococcus aureus in reclaimed water. The study found that simultaneous UV and chlorine disinfection significantly enhanced the inactivation efficacy by generating free radicals, which caused damages to cell membranes and suppressed bacterial metabolic activity and photoreactivation. UV/Cl also effectively removed heterotrophic bacteria and aromatic organic fluorophores.

Summary: This study focuses on the treatment of secondary urban wastewater to improve the effluent quality and reduce pathogenic microorganisms for safe reuse. Catalyst-free persulfate activation by radiation-based oxidation was applied as a treatment technology, and the potential beneficial role of bacterial competition in controlling the regrowth of harmful microorganisms was evaluated. The results showed that the treated wastewater diluted with 50% river water complied with the legislated limits for reuse.

Summary: Chemically enhanced primary treatment (CEPT) with ferrate(VI) was found to be effective in removing TSS, total COD, and total P from municipal wastewater by forming large-sized aggregates and facilitating sedimentation. Ferrate(VI) also demonstrated substantial removal of recalcitrant dissolved organic phosphorus and inactivation of bacterial indicators during the treatment process. Higher ferrate(VI) dose and weakly alkaline pH conditions were found to be favorable for the performance of ferrate(VI)-based CEPT.

Summary: The effectiveness of bifacial mixed metal-metal organic framework (MOF) anodes for municipal wastewater's photoelectro-catalytic (PEC) treatment is explored. The removal efficiency of pollutants from municipal wastewater and the impact of operational parameters are verified using TiO2-Bi(mixed metal)-MOF and TiO2-Sb(mixed metal)-MOF anodes in a visible light range. The study shows that TiO2-Bi(mixed metal)-MOF anodes in the PEC system play a positive role in removing micropollutants and disinfecting municipal wastewater, with high efficiency.

Summary: In this study, a persulfate-driven photo-Fenton-like process was applied to treat municipal wastewater, and the optimization of the treatment process for total organic carbon (TOC) removal was successfully achieved using response surface methodology (RSM) and artificial neural network (ANN). However, the attempts to find the optimal conditions for total carbon (TC) and total nitrogen (TN) removal using statistical, and neural network models were not successful.

Summary: This study evaluated black-box regression models as a modeling alternative for UV disinfection, synthesizing hydrodynamics, fluence rate, and inactivation kinetics. The two-part artificial neural network model showed the best predictive performance, handling non-linearities and a high proportion of null values in the dataset. The deployment of this model to control ultraviolet disinfection was simulated, estimating a plausible 63% energy saving.

Summary: Understanding the RO membrane fouling development at low feed water temperature is crucial for effective fouling control in wastewater reclamation. This study found that fouling development at a low temperature was milder, with less accumulation of foulants and biofilm on the RO membrane. Alkali cleaning was also more effective at alleviating membrane fouling at low temperature. The microbial community on the RO membrane gradually differentiated under the low temperature condition, with an increase in the relative abundance of Patescibacteria, which are adapted to oligo-trophic, low temperature, and high salt environments.

Summary: The study investigated the efficacy of a sulfite system activated by different iron species and/or UV-A radiation in inactivating Enterococcus sp., achieving complete disinfection after 90 min. Fe(III)-cit was found to be the best sulfite activator, while the use of real wastewater decreased the disinfection rate. The study also showed that the presence of Escherichia coli negatively influenced the Enterococcus inactivation result.

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.
