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. Identifying reducing MP contamination these facilities might stimulate more awareness, promote extensive scientific investigation, facilitate development informed policies.

Toxicological review of micro- and nano-plastics in aquatic environments: Risks to ecosystems, food web dynamics and human health

Ecotoxicology and Environmental Safety, Год журнала: 2024, Номер 278, С. 116426 - 116426

Опубликована: Май 8, 2024

The increase of micro- and nano-plastics (MNPs) in aquatic environments has become a significant concern due to their potential toxicological effects on ecosystems, food web dynamics, human health. These plastic particles emerge from range sources, such as the breakdown larger waste, consumer products, industrial outputs. This review provides detailed report transmission dangers MNPs environmental behavior, interactions within webs, emphasizing toxic impact marine life. It explores relationship between particle size toxicity, distribution different tissues, process trophic transfer through web. MNPs, once consumed, can be found various organs, including digestive system, gills, liver. Their consumption by lower level organisms facilitates progression up chain, potentially leading bioaccumulation biomagnification, thereby posing substantial risks health, reproduction, behavior species. work also how persistence bioaccumulation, pose biodiversity disrupt relationships. addresses implications for particularly contaminated seafood, highlighting direct indirect pathways which humans are exposed these pollutants. Furthermore, highlights recommendations future research directions, integration ecological, toxicological, health studies inform risk assessments develop mitigation strategies address global challenge pollution environments.

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. Compared existing literature, this adopts methodological approach combining optical microscopy, µRaman, SEM–EDX, enriching knowledge MP aiding future directions.

Evaluation of potentially toxic elements and microplastics in the water treatment facility

Environmental Monitoring and Assessment, Год журнала: 2024, Номер 196(5)

Опубликована: Апрель 25, 2024

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.
