Rising plastic waste from products such as contact lenses underscores the need for innovative recycling solutions. This study presents a sustainable approach to produce reusable photocatalytic hybrid nanocomposites water treatment through use of lenses. TiO2 nanoparticles were uniformly integrated into postused via controlled spray deposition technique, resulting in with different times (10, 15, or 20 min). The polymeric hybrids comprehensively characterized morphological, structural, and chemical standpoint using techniques scanning transmission electron microscopy, thermogravimetric analysis, X-ray diffraction Raman spectroscopy, Z-potential UV–vis Fourier transform infrared spectroscopy. UV-photocatalytic performance systems was successfully tested on two common pollutants: methylene blue (a cationic dye) sodium dodecyl sulfate (an anionic surfactant). highest efficiency obtained min spray-coated lenses, able degrade ∼100% MB ∼60% SDS within 3 h UV-light irradiation. difference attributed electrostatic interaction between individual pollutant material's surface. In addition, antibacterial activity assessed Escherichia coli, well-known indicator fecal contamination. research paves way an affordable cost-effective production method that aligns circular economy principles.

Microplastics (MPs) are emerging contaminants characterized by persistence, cross-media transport, and complex pollutant interactions, posing serious ecotoxicological risks to ecosystems human health. Effective MPs management requires multi-faced, long-term, strategies involving targeted sampling, quantitative detection, comprehensive risk assessments, all of which entail significant resource investment. Despite advancements in remediation technologies, a holistic governance framework integrating these innovations remains underdeveloped. This review synthesizes current knowledge on MPs, elaborating their diverse morphologies, degradation pathways, role as vectors for toxic substances. State-of-the-art extraction techniques evaluated this article, including micropore adsorption using nanocomposites, alongside the incorporation advanced analytical tools such spectroscopic methods, electron microscopy, bioinformatics augment environmental forensics. also underscores necessity formulating robust global policies regulate pollution discusses potential biodegradation thermal sustainable solutions removal. By promoting an interdisciplinary approach, advocates coordinated response, science, policy frameworks, waste mitigate escalating impact well-being.

Microplastic pollution has become a global environmental problem that cannot be ignored. Raman spectroscopy been widely used for microplastics detection because it can performed in real-time and is non-destructive. Conventional techniques have had weak signals low signal-to-noise ratios (SNR). Here, an efficient reliable method demonstrated. Specifically, confocal microscope combined with echelle-grating spatial-heterodyne spectrometer (CM-ESHRS) was constructed. The microscopy the characteristics of echelle grating enabled high optical throughput, SNR, spectral resolution, wide band. After calibration, resolution approached 0.67 cm

Abstract The present review discusses the growing concern of microplastics (MPs) and nanoplastics (NPs) in soil, together with their sources, concentration, distribution, impact on soil microorganisms, human health, ecosystems. MPs NPs can enter through various pathways, such as agricultural activities, sewage sludge application, atmospheric deposition. Once they accumulate upper layers affect structure, water retention, nutrient availability. presence also have ecological consequences, acting carriers for pollutants contaminants, heavy metals persistent organic pollutants. Additionally, leaching chemicals additives from pose public health risks food web groundwater contamination. detection analyses be challenging, methods involve spectroscopic microscopy techniques, Fourier‐transform infrared spectroscopy scanning electron microscopy. To mitigate effects it is essential to reduce plastic waste production, improve management practices, adopt sustainable practices. Effective mitigation measures include implementing stricter regulations use, promoting biodegradable alternatives, enhancing recycling infrastructure. amendments, biochar compost, help immobilize NPs, reducing mobility bioavailability. This article aims provide a comprehensive understanding these emerging environmental issues identify potential solutions alleviate ecosystem functioning, community health.
