Urban areas play a key role in the production of microplastics (MPs) and their entry into water bodies. This article reviews literature on sources, transport, control MPs urban environments with aim clarifying mechanisms underlying these processes. Major MP sources include atmospheric deposition, micro-litter, tire road wear particles (TRWPs). deposited from atmosphere are mostly fibers may be particularly important catchments without traffic. Littering attrition textiles plastic products is another source. However, quantities originating this source hard to estimate. TRWPs significant arguably best quantified The mobilization poorly understood but it appears that dry unconsolidated sediments deposits most readily mobilized. Sequestration occurs green understood. Consequently, some authors consider green/pervious parts sinks. Field studies have shown appreciable removal stormwater quality facilities. Street cleaning snow also remove (particularly TRWPs), efficacy measures unknown. Among management facilities, biofiltration/retention units seem more effectively than facilities relying settling. knowledge remains incomplete. Finally, although 13 research papers reported concentrations stormwater, total number field samples examined was only 189. Moreover, results not necessarily comparable because they based relatively small numbers differ widely terms objectives, sites, analytical methods, size fractions, polymers, even terminology. area can thus considered "data-poor" offers great opportunities for further many areas.

Microplastics in the urban atmosphere: Sources, occurrences, distribution, and potential health implications

Journal of Hazardous Materials Advances, Год журнала: 2023, Номер 12, С. 100346 - 100346

Опубликована: Июль 20, 2023

Urbanization itself is a major and furthermost imperative contributor to the release of microplastics into environments. As cities grow develop, more plastic products are consumed discarded, resulting in increased pollution levels. Although researches on airborne (AMPs) urban regions scare, recent findings have shown high concentration them air residential areas. Textiles main source indoor ambiance, while traffic-related particles, textiles agricultural marine appear be responsible for polluting cities' outdoor atmosphere. Local metrological situation, topography physical features particles control behavior, distribution fate microplastics. Inhalation primary exposure route may induce toxicity respiratory tract. Understanding these factors crucial developing effective strategies mitigate their impact human health environment. Current work reviews published literature settings aiming at characterizing parent's materials, potential sources both spaces, possible impacts along with some further suggestions.

Plastics have been extensively used in the building and construction industries for decades. However, more plastics are utilised, microplastics released. This review analysis article summarises organises knowledge from 211 current related publications published 2014–2022. The explain kinds of employed built environment. Fabrics or textiles, fibres cementitious systems, paints, tyres roads discussed. entry points into human body reviewed next, followed by management recycled wastes. important research gaps possible solutions include using high-strength concretes surface-hardening agents is suggested to encapsulate inside matrix; DPSIR model can be holistically adopted each composite; innovative bio-chemical technology like self-healing concrete bio-degradable a viable choice; social science, law urban planning support awareness comprehension.

Automated identification and quantification of tire wear particles (TWP) in airborne dust: SEM/EDX single particle analysis coupled to a machine learning classifier

The share of non-exhaust particles, including tire wear particles (TWP), within the airborne dust and particularly PM10 has increased in recent years due to a significant reduction other exhaust road traffic emissions. However, quantification TWP is demanding task non-specificity tracers, fact that they are commonly contained analytically challenging low concentrations (e.g. Zn, styrene, 1,3-butadiene, vinylcyclohexene). This difficulty amplified by chemical morpho-textural heterogeneity resulting from interaction between tires surface. In contrast bulk techniques, automated single particle SEM/EDX analysis can benefit ubiquitous environmental as diagnostic criterion for their identification quantification. For this purpose, we follow machine-learning (ML) approach makes use an extensive number (67) morphological, textural (backscatter-signal based) descriptors differentiate into following classes: TWP, metals, minerals biogenic/organic. We present ML-based model developed classify samples (trained >100,000 6841 TWP), its application one-year monitoring campaign at two Swiss sites. study, mass fractions PM80-10, PM10-2.5 PM2.5-1 were determined. Furthermore, size distribution shape characteristics 5621 evaluated. A cut through means FIB-SEM evidences mineral metal typically found not only on surface but also throughout complete volume. At urban background site, annual average fraction micro-rubber was 1.8% (0.28 μg/m3) 0.9%, respectively. kerbside corresponding values 6 times higher amounting 10.5% (2.24 5.0% micro-rubber.

Tire and road wear particles (TRWPs) are generated from friction between tires the contain polymer tread with pavement encrustations. Single particle analysis (SPA) of tire source contribution in environmental samples has been limited by interferences common spectroscopic techniques. This study extends a density separation chemical mapping protocol for simulator TRWPs toward identification characterization individual more complex dust, road-dust-spiked artificial sediment, tunnel settling pond sediment samples. were identified combination physical (elongated/round shape variable amounts mineral encrustation) elemental surface characteristics [co-localization (S + Zn/Na) ± (Si, K, Mg, Ca, Al)]. Organic markers (C7H7+), overlapping FTIR spectra reference material, resistance to heat-induced deformation selectively used confirm identification. The TRWP size displayed an increasing average trend 54, 158, 267 μm number (94, 224, 506 volume) respectively. distributions within dust 10× diluted agreed those pure dust. Our SPA methodologies determined distribution sample types complexity.

Microplastic pollution of stormwater can be a serious threat to the environment. Gross pollutant trap (GPT) - bioretention treatment trains have been shown previously treat (inter alia) particulate pollutants including microplastic particles larger than 100 μm. This study was carried out investigate whether such also remove smaller 20 μm sized from highway runoff. Further, it investigates occurrence and concentration in runoff which polymer types they assigned to. Volume proportional samples nine rain events were taken incoming stormwater, gross effluent outflow system as well non-vegetated sand filter. The analyses using μFTIR FTIR-ATR, made possible detect where carbon black present. It found that are abundant their concentrations highly variable, with median 230 particles/L, minimum 42 particles/L maximum 8577 particles/L. dominant Polypropylene (PP), Ethylene Propylene Diene (EPDM) rubber Ethylene-vinyl acetate (EVA). train treated 200 significantly better filter, 26.5 121 respectively.
