The increasing prevalence of nanoplastics in the environment underscores need for effective detection and monitoring techniques. Current methods mainly focus on microplastics, while accurate identification is challenging due to their small size complex composition. In this work, we combined highly reflective substrates machine learning accurately identify using Raman spectroscopy. Our approach established spectroscopy data sets nanoplastics, incorporated peak extraction retention processing, constructed a random forest model that achieved an average accuracy 98.8% identifying nanoplastics. We validated our method with tap water spiked samples, achieving over 97% accuracy, demonstrated applicability algorithm real-world environmental samples through experiments rainwater, detecting nanoscale polystyrene (PS) polyvinyl chloride (PVC). Despite challenges processing low-quality nanoplastic spectra study potential forests distinguish from other particles. results suggest combination holds promise developing particle strategies.

Microplastics are widely present worldwide and of great concern to scientists governments due their toxicity ability serve as carriers other environmental pollutants. The abundance microplastics in different water bodies varied significantly, mainly attributed the initial emission concentration pollutants migration process determines abundance, fate, bioavailability water. Previous studies have proved that physicochemical properties themselves important factors affecting migration, but change external conditions is also one main controlling microplastics. In this paper, we focus on effects meteorological (rainfall, light, wind) distribution conclude influence affects inflow microplastics, physical chemical water, dynamics At same time, briefly summarized aquatic organisms, substrates, topography It believed organisms can affect through adsorption vivo transmission plants, feeding behavior, swimming, metabolism animals, extracellular polymers formed by microorganisms, original processes bodies.

The escalating prominence of micro- and nanoplastics (MNPs) as emerging anthropogenic pollutants has sparked widespread scientific public interest. These minuscule particles pervade the global environment, permeating drinking water food sources, prompting concerns regarding their environmental impacts potential risks to human health. In recent years, field MNP research witnessed development application cutting-edge infrared (IR) spectroscopic instruments. This review focuses on advanced IR techniques relevant instrumentation analyse MNPs. A comprehensive literature search was conducted, encompassing articles published within past three years. findings revealed that Fourier transform (FTIR) spectroscopy stands most used technique, with focal plane array FTIR (FPA-FTIR) representing cutting edge in spectroscopy. second popular technique is quantum cascade laser (QCL-IR) spectroscopy, which facilitated rapid analysis plastic particles. Following closely optical photothermal (O-PTIR) can furnish submicron spatial resolution. Subsequently, there atomic force microscopy-based (AFM-IR) made it feasible MNPs at nanoscale level. instruments identified covered this were compared. Comparison metrics encompass substrates/filters, data quality, resolution, acquisition speed, processing cost. limitations these identified, recommendations address proposed. offer valuable guidance researchers selecting suitable for experiments, thereby facilitating advancements aimed enhancing our understanding health associated
