Road dust is one main sources environmental microplastics, and thus an ideal window to reveal occurrence pattern. The differences function zones, infrastructure, natural condition may pose complex effects driving characteristics microplastics road simultaneously, but rare reports studied these features at a city scale. In this study, we used Nanjing, super-large eastern China, as research area, conducted two-seasons investigation explore spatiotemporal pattern dust. abundance Nanjing reached 143.3 ± 40.8 n/m2, fragments tire wear particles whose size < 100 µm dominated morphology. temporal variation was smooth, whereas spatial distribution showed significant among different types functional zones. commercial zones heavy industrial suffered heaviest pollution dust, following residential educational & cultural 29 polymer were identified, polystyrene (PS), polyamide (PA), polyvinylidene difluoride (PVDF), cellophane predominate. light zone unexpectedly exhibited slight contamination still contained components type.

Microplastic pollution in karst systems is still poorly studied, despite the presence of protected species and habitats, important water reserves. Vulnerable key hosted these habitats could consume or assimilate microplastics, which can irreversibly damage management efforts, thus ecosystems functionality. This be particularly true for subterranean where microplastic effects on wildlife programs are not considered. The aim this study to provide a case from Classical Karst Region, hosts peculiar at European level, such as olm Proteus anguinus. As area has been deeply exploited modified over time, adjacent highways, roads railways, contribute within system, threatening ecosystems, it provides perfect model system. In we collected investigated sediment samples aquatic environments surface hosting several environment-adapted organisms. Examined particles were counted characterized by size, color shape via visual identification under microscope, with without UV light. Furthermore, spectroscopic analyses carried out order identify microplastics typology. Microplastics found all examined habitats. water, concentration ranged 37 86 items/L, sediments 776 2064 items/kg. Fibre-shape was main present, followed fragments beads, suggesting multiple sources pollution, especially textile products. Most fluorescent light mainly transparent, while not-fluorescent ones black, blue brown. Samples contained polyesters copolymers. These results highlight intense MP areas, significant impacts quality, potential environment-dwelling species. We stress importance monitoring critical biodiversity habitat conservation: areas must become priority protection, resources management, improving larger number

Abstract Microplastics (MPs) can be transported into clouds, where they may act as ice nucleating particles (INPs). However, MPs have not been considered contributors to INP concentrations. Here, we quantify road traffic‐related MP number concentrations, and estimate their contribution total concentrations using the atmospheric transport model FLEXPART. We find that under a high emission scenario ice‐active account from about 0.1% more than 40% of in immersion freezing conditions tropics, whereas for cirrus conditions, up 7% over tropical Pacific 20% East Antarctica. Thus, regions other effective INPs are rare, sufficient trigger heterogeneous nucleation crystals mixed‐phase clouds or cirrus. This suggests affect cloud formation highlights need reduce uncertainty emissions fate atmosphere plastic use continues grow.

Abstract Uncertainties in the quantification of microplastics various products arise from applied pretreatment processes. Road dust, a significant source microplastics, requires precise methods to ensure accuracy. In this study, we examined impact processes on accuracy microplastic road specifically focusing tire rubber particles. We compared effects cellulolytic enzyme (EZM) and Fenton (FT) treatments by analyzing changes particle number, size, shape, identification for each treatment. Both increased number particles, reduced their made them more spherical. Notably, FT treatment resulted smaller parameters (Feret, MinFeret, Major, Minor, Area) EZM Identification also varied, with 89% particles identified after treatment, 51% Furthermore, volume was overestimated 4.5% following underestimated 21% These findings demonstrate that procedures significantly influence quantification. Our study underscores need further research determine whether current estimates are accurate, as estimated can change due organic removal Practitioner Points Pretreatment eliminate materials is necessary improving efficiency analysis.
