Summary: This study examined the presence of microplastics in the Llobregat river basin in Catalonia, Spain, and their removal efficiency in the drinking water treatment plant (DWTP). Sand filtration was identified as the key stage in microplastic removal, with ultrafiltration/reverse osmosis proving more effective for removal than ozonation/carbon filtration. Preliminary migration tests were also conducted to identify potential sources of microplastics in each treatment step.

Summary: This article studied the coagulation behavior of microplastics (MPs) that are difficult to remove during drinking water treatment. The results showed that both the size and concentration of MPs had a significant impact on coagulation, with size being the main factor. The type of MPs did not have a significant effect on coagulation. After optimization of operating conditions, the removal efficiency of MPs with a size ≥13 μm could reach over 70% using PAC and PAM. In the coagulation process, PAC played the most important role through electrical neutralization, while PAM's adsorption bridging and net sweeping assisted in coagulation.

Summary: In this study, the distribution and fate of microplastics in different water sources and treatment plants in France were investigated. Wastewater was found to contain the highest concentrations of microplastics, followed by surface water/groundwater and seawater. Polyethylene was the most common type of microplastic, followed by polypropylene, polystyrene, and polyethylene terephthalate. Most treatment technologies were effective in removing microplastics, although some processes or pipes could introduce additional contamination. Ultrafiltration was confirmed to be an effective technology for microplastic retention and size control.

Summary: This study investigates the behavior of microplastic particles (MPPs) in a lab-scale direct contact membrane distillation system and analyzes their impact on the process performance. The temperature stress tests were performed on commercial MPPs, and uPVC was selected for further experiments. The results show that high loads of uPVC MPPs can decrease the distillation performance, but the treated water quality remains unaffected. The analysis also reveals that membrane distillation has a high efficiency in the removal of MPPs in seawater applications.

Summary: Diseases caused by antibiotic-resistant Aeromonads are common and troublesome in aquaculture. In this study, the antibacterial efficacy of Cymbopogon flexuosus essential oil was investigated against OTC-resistant and sensitive strains of Aeromonas hydrophila. The oil exhibited dose-dependent growth inhibition of the bacteria and showed effectiveness against OTC-resistant isolates. Molecular docking experiments revealed that some components of the oil strongly bonded with DNA gyrase-B, inhibiting its efficacy. The identified phytochemicals had favorable physicochemical and pharmacokinetic properties and satisfied the rule of five (Ro5).

Summary: In this study, polyvinyl alcohol (PVA) capped AgNPs (AgNPs@PVA) were used as a nanocarrier to fabricate an acetylcholinesterase (AChE) biosensor for the detection of organophosphate (OP) pesticides. The AChE enzyme was immobilized onto a drop casted AgNPs@PVA layer on a glassy carbon electrode (GCE) to fabricate the electrochemical biosensor. The biosensor measured the peak current at 0.6 V generated by the AChE-mediated hydrolysis of acetylthiocholine (ATCl) to thiocholine and its subsequent oxidation to dimer through differential pulse voltammetry (DPV). A model OP pesticide, malathion, was used to hinder the AChE hydrolysis activity of the sensor probe, and the inhibition effect was found to be proportional to the concentration of malathion. The fabricated biosensor showed linearity in the range of 0.01 to 1 ng/mL of malathion at optimal conditions, with a detection limit (LOD) of 2.6 pg/mL. The AChE biosensor exhibited good selectivity for OP pesticides and demonstrated efficiency in real sample analysis.

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.
