Summary: The study tested the purifying performance of three different Moringa oleifera varieties cultivated in Tunisia on raw and secondary treated urban wastewater. The Egyptian variety showed the best results in reducing pollutants in both types of wastewater. High levels of TKN were found in Moringa-treated wastewater, making it suitable for agricultural irrigation and reducing the need for chemical nitrogen fertilizers.

Summary: The review discusses the potential of natural coagulants for removing pharmaceutical compounds from water, highlighting their advantages such as biodegradability, safety, and availability compared to chemical coagulants. The main mechanisms of natural coagulants for pharmaceutical removal are charge neutralization and polymer bridges, with plant-based coagulants being more commonly studied due to their affordability. Further research is needed to develop reliable extraction methods and understand the effects of environmental factors, as natural coagulants have potential in providing green water and wastewater treatment technologies.

Summary: The improved method for active coagulant agent extraction from Moringa Oleifera seeds powder using sodium chloride as solvent at 1.0 M concentration showed the best performance in turbidity removal and biochemical oxygen demand (BOD5) removal for municipal wastewater treatment. Ultrasonic treatment was considered as an additional method, but it decreased the active coagulant agent extraction efficiency, indicating its inconvenience for Moringa Oleifera coagulation activity.

Summary: Currently, composites with natural fillers, such as spent coffee grounds (SCG), are gaining attention due to their potential as reinforcement materials in thermo-plastic matrices. This study investigated the long-term effect of activated sludge microorganisms on the mechanical properties of composites with SCG as filler. The research confirmed that the increased ratio of coffee grounds in the composite leads to increased diversity and abundance of microorganisms, with the highest number observed in the composite with 40% SCG. Ciliates, especially Epistylis genus, were the most common group of microorganisms in the samples after immersion in the bioreactor.

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.
