Abstract Microplastics (MPs) have become a growing concern in the context of environmental pollution, with an increasing focus on their presence indoor environments, including university facilities. This study investigates and characteristics MPs different environments. Initial examination ambient involved physical characterization through optical microscopy, focusing classifying by shape color. Various types MPs, fibers, fragments, pellets, foams, films, lines, were identified, most common colors being black, red, blue, brown. Fragments predominant type found, although accurately quantifying numbers proved challenging due to dense sample content. These displayed rough irregular margins suggestive abrasion. Subsequent chemical elemental was conducted using micro-Raman SEM-EDX, revealing 25 PA 66, PTFE, PP, HDPE, PE. The indicates that inhabitants are exposed airborne (≥ 2.5–336.89 μm) at inhalation rates 13.88–18.51 MPs/m 3 180–240 daily. exhibited significant variations size, distribution varied among environments studied. SEM-EDX analysis revealed elements identified C, O, F, Na, Cl, Al, Si, others consistently detected. research is first comprehensively analyze nine active sampling.

Abstract The pollution caused by microplastics (MPs) is a growing concern on global scale, especially considering the significant proportion of time that individuals spend indoors. contamination in question has potential to directly impact human population through exposure indoor dust and air. This research undertook comprehensive analysis deposition MPs university classrooms, employing various investigative tools. present study aimed comprehensively analyze physical chemical properties found classrooms. Analyzing samples under stereomicroscope, predominant were identified as fibers varied colors, mainly attributed clothing. Sizes these significantly across different with general average size range 120–2222 µm. observed morphological changes MPs, including cracks grooves, hint at degradation into nanosized plastics over time. observation raises concerns about increased concentrations nanoplastics environments. Using µRaman analysis, eleven types identified, potentially originating from clothing, shoes, stationery. majority polyamide 6, polypropylene, 12. scanning electron microscope energy-dispersive X-ray spectroscopy (SEM–EDX) technique unveiled elemental composition carbon, fluorine, oxygen being dominant. findings align past studies but highlight need understand MPs' structural components any possible contaminants.

Abstract The potentially harmful effects of consuming toxic elements (PTEs) and microplastics (MPs) regularly via drinking water are a significant cause for worry. This study investigated PTEs (Cd, Cu, Cr, Ni, Pd, Zn, Co), MPs, turbidity, pH, conductivity, health risk assessment in the treatment plant Kielce, Poland. Zn had highest concentrations throughout facility, whereas Cd, Pb, Co lower (< 0.1 µg/L). order among specified was like Zn˃Cu˃Ni˃Cr˃Cd˃Pb Co. minimum turbidity 0.34, maximum 1.9 NTU. range pH samples 6.51—7.47. conductivity 1,203—1,445 ms samples. These identified MPs were categorized into fiber fragments. color these blue, red, black, green, transparent. size 196 4,018 µm, while average 2,751 ± 1,905 µm. concentration per liter 108.88 55.61. listed C, O, Na, Mg, Al, Si, K, Ca, Ti. Fe predominant seen using EDX. HQ values less than one adults children. human associated with all detected revealed that exhibit satisfactory degree non-carcinogenic adverse risk. HI children age groups one. In most samples, carcinogenic value exceeds threshold 10 −6 . MP should be periodically monitored to minimize consumers' environmental pollution risks.

The rising trend of plastic production in last years and the inadequate disposal related waste has raised concerns regarding microplastic-related environmental issues. Microplastic particles disperse by means transport deposition processes to different ecosystems enter food chains. In this paper, atmospheric foliage samples two species (i.e., Hedera helix Photinia glabra) were collected analysed for quantity identity microplastics (MPs). A preliminary methodology treat subsequently identify MPs using a quantum cascade laser IR spectrometer is presented. treatment airborne involved filtration, mild digestion, concentration, transfer onto reflective slides whereas that washing, transference putative slides. Fibers fragments differentiated according their physical features (size, width, height, etc.) calculating derived characteristics (namely, circularity solidity). results obtained suggest good agreement between atmospheric-deposited foliage-retained MPs, showing capability leaves act as passive samplers monitoring.
