Summary: The UV and US enhanced ozonation method showed positive effects on the removal of atrazine and COD in atrazine manufacturing wastewater, particularly within a limited energy range. The interaction of O-3 with UV promoted the degradation of both COD and atrazine, while its interaction with US inhibited COD removal but promoted atrazine removal. The most optimal removal rate of atrazine was achieved under specific conditions, and the most energy-efficient configuration was identified for advanced oxidation processes.

Summary: The study focused on treating wastewater from rayon fiber production. Mass balance and repeated analysis were conducted on three sources of problematic process wastewater. The high COD (0.4-30 g/L), TOC (0.09-7.1 g/L), and Zn2+ (0.09-0.5 g/L) concentrations in all three sources pose a significant pollution threat to the Elbe River (with a total volume of 1.84 million m3). Lab-scale tests were done using filtration, microfiltration, and oxidation methods, along with the adsorption of Zn2+ emissions using cation exchange resin. The optimized technological sequence achieved up to 98% COD reduction and 85% TOC reduction, while also converting Zn2+ emissions into reusable zinc sulfate during the cation regeneration process.

Summary: This study investigates the occurrence, distribution, seasonal variation, and removal of pesticides in three different types of wastewater treatment plants. The results show that the removal efficiency of atrazine (ATZ) is higher compared to chlorpyriphos (CPR) and chlorfenvinphos (CFV). ATZ is mainly removed in the primary treatment stage, while CPR and CFV are primarily removed in the biological treatment stage. Sorption onto sludge is found to be an effective removal mechanism for pesticides. The highest removal efficiency is observed for ATZ in the liquid phase under anaerobic conditions.

Summary: tau's paper proposes a sustainable treatment scheme for effluents from fruit and vegetable processing industries with high organic load. The scheme involves cultivating heterotrophic microalgae and using microalgae spray drying to produce commercial end-products (biofertilisers and/or animal feed). The pilot plant, powered by renewable energy, demonstrated that the produced algae could be commercialized as a solid NPK organic fertilizer and efficiently included in animal feed. The proposed solution illustrates the circular economy concept and has significant environmental benefits.

Summary: This study investigated the transport of microplastic-oil-dispersant agglomerates (MODAs) in a simulated ocean system and explored related mechanisms under different conditions. It was found that heavy oil-formed MODAs mainly stayed at the seawater surface, while light oil-formed MODAs were distributed throughout the seawater column. Increased salinity promoted the transport of certain MODAs, and minerals facilitated the sinking of large microplastic-formed MODAs. The study proposed a MODA-mineral system and recommended Rubey's equation for predicting sinking velocity.

Summary: This review examines the interaction between microplastics/nanoplastics and co-existing contaminants, such as organic contaminants, potentially toxic elements, and metal/metal-oxide nanoparticles. The characteristics of the plastics, including polymer type, size, functional groups, and weathering, influence their combined effects with the co-existing contaminants. Mixture toxicity is not only affected by these factors, but also by the type of contaminants, their concentrations, exposure time, dissolved organic matter, and surfactants. Different organisms show different responses to the complex system. Organic contaminants can be biodegraded, which may enhance or alleviate mixture toxicity. Potentially toxic elements can be adsorbed and desorbed under changing environments, further affecting the combined effects. The presence of metal/metal-oxide nanoparticles is more complicated, as some particles may release ion metals, increasing the contaminant composition.

Summary: This study found that the presence of elemental sulfur (S0) in sulfidated zero-valent iron (S-ZVI) can enhance the removal of Cr(VI) and improve recyclability when compared to FeS or iron polysulfides (FeSx, x > 1). The formation of micro-galvanic cells, the semiconductor properties of cyclo-octasulfur S0 with Fe2+ substitution, and the in situ generation of highly reactive iron monosulfide (FeSaq) or polysulfides precursors (FeSx, aq) were identified as the reasons for this improved performance. The interaction between S0 and ZVI required direct contact and overcoming the spatial barrier caused by FexSy formation.

Summary: This study is the first to investigate the effects of freeze-thaw (FT) and microplastics (MPs) on the distribution of antibiotic resistance genes (ARGs) in soil aggregates. The results showed that FT increased the relative abundance of ARGs in different aggregates by promoting the growth of intI1 and ARG host bacteria. However, polyethylene MPs hindered this increase caused by FT. The study also revealed that FT, MPs, and their integration promoted the proliferation of human pathogenic bacteria in soil aggregates.

Summary: The transition in the energy mix has increased the need for accurate emissions reporting in the petroleum supply chain. Current carbon footprint assessments lack resolution and traceability, leading to poor visibility into carbon intensities in crude oil trading. Through the use of high-fidelity datasets and optimization algorithms, this study reveals significant variability in carbon intensities at the level of crude trade pathways. By prioritizing low-carbon supply chain pathways, additional CO2-equivalent savings can be realized.

Summary: Micro-nano metal-organic framework (MIL-68(Fe)) and a MIL-68(Fe)/chitosan composite sponge (MIL-68(Fe)/CS) were successfully prepared for efficient adsorption of azo anionic dye Congo red (CR). The MIL-68(Fe)/CS showed faster adsorption kinetics and easier desorption than MIL-68(Fe). The adsorption process of MIL-68(Fe)/chitosan composite sponge on CR is a complex physicochemical process, influenced by factors such as pH, contact time, adsorbent dosage, initial solution concentration, and temperature. The removal rates and adsorption capacity of CR by MIL-68(Fe)/chitosan composite sponge reached high values, and the synergistic effects of different interactions contributed to the CR removal.

Summary: This study evaluates the performance of ozonation and adsorption as in-series processes compared to standalone processes for the removal of Contaminants of Emerging Concern (CECs) in drinking water. The combination of both processes proves to be more effective than adsorption and ozonation alone. Ozonation improves the adsorption performance of poorly-oxidizable CECs but worsens that of well-oxidizable compounds. This research highlights the importance of considering both processes in the removal of CECs in drinking water treatment plants.
