Summary: Plastic pollution is a growing concern as plastic particles are found in the atmosphere, land, and water due to various pathways. Recent research has shown that plastic particles are present everywhere, from the Arctic to the Antarctic. The ingestion of plastic by all living organisms is natural given the widespread microplastic pollution in the environment. The accumulation of microplastics poses a threat to living beings, and its consequences are still being studied. This review highlights the research conducted by scientists on microplastics in different drinking water sources, emphasizing the need for a uniform protocol for analyzing microplastics quantitatively and qualitatively. It is crucial to address and expand research on microplastic pollution as an ongoing environmental concern.

Summary: The supply of safe drinking water is a prominent global challenge, mainly due to chemical and biological toxins. Nanomaterial-based sensors, particularly plasmonic sensors, have provided solutions for ultra-sensitive detection, with noble metal nanoparticles of gold and silver playing a key role. The emphasis on design and fabrication of plasmonic sensors has been crucial in enhancing their affinity towards specific pollutants, leading to more effective and efficient on-site detection of toxin contaminants.

Summary: With the growing scarcity of water resources and increased awareness of environmental protection, traditional water pollution control technology falls short of meeting the demands of environmental development. In recent years, the rapid progress in nanotechnology and nanomaterials has opened up new opportunities for innovation in water treatment technology and gained extensive attention from environmental researchers. Magnetic nanomaterials, with their excellent adsorption properties, chemical stability, easy regeneration, and solid-liquid separation, have become a popular research topic in the field of water pollution control. This paper provides an overview of the research progress of magnetic nanomaterials, including their remarkable characteristics, preparation methods, and applications in water pollution control. Conclusive remarks and future trends are also discussed.

Summary: Quinolone antibiotics are widely used in the treatment of human and animal diseases due to their strong antibacterial activity, stable metabolism, and low cost. However, they often cause environmental pollution as they cannot be completely digested and are excreted in urine and feces. The pollution status, biological toxicity, and removal methods of these antibiotics were reviewed, revealing their ecotoxicity and potential for inducing drug resistance.

Summary: This study modeled and experimentally studied the dynamic behavior of magnetite nanoparticles (MNPs) released in a water flow under an external magnetic field. The physical and magnetic properties of MNPs and their tendency to form aggregates were investigated. The study found that MNPs have shorter trajectories in flow regions farther from the duct walls, where frictional forces are lower. The study also showed that MNPs can be attracted even in regions with a weak magnetic field. Additionally, the size of MNP aggregates significantly affects particle dynamics, but does not greatly impact overall removal efficiency for aggregate diameters larger than 1.2 mu m.
