Abstract The environment provides endless assistance for the wellbeing of all living organisms. However, can be stressed due to anthropogenic and non-anthropogenic pollutants. Plastics have been identified as a persistent pollutant that has stressing over few decades. Among these hazardous plastics, accumulation microplastics (MPs) growing global issue. MPs are generally defined small pieces plastic less than 5 mm in diameter. Considering source, two categories identified, primary secondary MPs, it recognized released into during production, transportation, product usage, maintenance. Different processes including physical, chemical, photodegradation, biological degradations tend break plastics MP fragments, which include well nanoplastics. degradation processes, physical is prominent coastal regions, chemical occur corrosive chemicals, acids, gases, atmospheric pollutants, was case recent MV X-Press Pearl disaster Indian Ocean. methodologies applied pretreatment, separation, detection, identification, quantification MPs. Digestion complex substances ultracentrifugation or ultrafiltration utilized pretreatment methods, whereas density, magnetic electrostatic separations, filtration, size-exclusion chromatography practiced separation methods Scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, atomic force (AFM), mass spectrometry main analytical detection. ecological risk affects marine environment, freshwater soil ultimately influencing human health. To remediate issue, removal being developed, with currently progressing sorption ingestion, treatments, membrane separation. prospects, need conduct meta-analyses, compare data from different studies done various geographic regions important, which, among other related topics such policy development, discussed thoroughly through this review article.

Marine microplastic pollution has emerged as a pressing environmental issue, with significant implications for aquatic ecosystems, human health and global biodiversity. Ports, acting semi-enclosed environments, are critical zones where plastic waste, including microplastics, fragments smaller than 5 mm, tend to accumulate. These settings provide controlled conditions that ideal deploying innovative solutions monitor mitigate the impact of pollution. This paper presents design, development initial testing an autonomous surface drone engineered specifically collect microplastics in port environments. Unlike traditional marine drones, this device operates exclusively at water surface, leveraging mechanical filtration systems capture quantify fragments. Designed cost-efficiency, ease manufacturing operational simplicity, aligns principles sustainability scalability. By integrating readily available materials modular components, it offers replicable model addressing localized systems.

Microplastics (MPs) have been identified in diverse settings, including drinking water, freshwater, food, air, and marine environments. This study employed stereomicroscopic µ-Raman techniques to analyze water samples from ten widely consumed bottled brands, aiming detect characterize MPs. Additionally, the oral consumption of MPs per capita was estimated. The average abundance ranged 9 ± 1.00 MPs/L 3 1.73 across all brands. Various shapes were observed, fibers, fragments, films, pellets, with fibers being predominant (58.928%). categorized by color into five groups (red, blue, black, yellow, transparent), red comprising approximately 35.714% total count. All less than 500 µm size. analysis validated presence eight different polymer types samples, namely Polypropylene (PP) (37.5%), Polymethyl methacrylate (PMMA) (3.571%), polystyrene (PS) (33.928%), polycarbonate (PC) polybutylene1 (PB1) (14.2%), Isotactic polypropylene (iPP) (7.142), Nylone 6-α polymorph (αNY6) (5.357%), polyvinyl alcohol (PVOH) (1.785%). estimated daily intake person determined be 0.42 MPs, translating an annual 153.3 person. origin likely attributed both raw sources packaging materials, underscoring need for further investigation.

This work employs the spatial econometric model to explore potential relation between condition of marine ecosystems and rapid development digital economy (DE), focusing on coastal area China. While environmental benefits DE are well studied regarding land atmospheric pollution, its influence pollution (MP) remains underexplored, this aims fill in gap. By analyzing panel data from 42 cities China using a Durbin examine both direct indirect impacts MP, results highlight positive role that plays reducing benefitting not only local environments but also those neighboring areas through non-negligible spillover effects. In addition, we find non-linear, inverted U-shaped relationship MP. These further confirmed extensive robustness tests. enriches field economics by reporting first empirical study offers policy recommendations optimize technologies for preservation.
