Environmental pollution of microplastics (MPs) is known to be anthropogenically mediated menace biosphere and becoming a debatable concern globally. Large quantities plastic fragments are left behind after crop cultivation. The leftover debris, gradually degrade into minute with diameter less than 5 mm, as MPs. MPs responsible for many changes in the soil physicochemical characteristics, including porosity, enzymatic activities, microbial plant growth, yield. Because their ubiquitous nature, high specific surface area strong hydrophobicity, play an important role transportation toxic chemicals such plasticisers, polycyclic aromatic hydrocarbons (PAHs), antibiotics, potentially elements (PTEs). may transported deep can pollute underground water. This review paper investigates deleterious effects on environment, microbes, flora, fauna production, highlights general concept contamination well its possible environmental consequences. also converses some key areas future research stakeholders concerned policymaking

The Science of The Total Environment, Год журнала: 2021, Номер 805, С. 150431 - 150431

Research on microplastics (MPs) in the terrestrial environment is currently at a still embryonal stage. The current knowledge concerning poorly known diffuse sources of MPs pollution ecosystems have been considered this work. In addition, particular focus presence, mechanism absorption and effects plants has also provided. urban areas their intake by Tyre Road Wear Particulates (TWRP) demonstrated high contribution plastic debris to microplastic pollution, although quantification these inputs challenging assess because studies are very few. Around 50% particles expected remain roadside soil, while rest transported away runoff with concentrations TRWP size ranging between 0.02 0.1 mm. Natural anthropic environments like temporary ponds, stormwater retention ponds small waterbodies were sensitive connecting rich biodiversity aquatic environments. Even if not yet exhaustive just eight published ecosystems, considerable values already observed both sediment water phase ponds. Although explored, agricultural hide significant number linked mainly activities practices (e.g. mulch, sewage compost fertilisation). However, transportation processes into soil understudied, few works available.

Occurrence and risks of 23 tire additives and their transformation products in an urban water system

Environment International, Год журнала: 2022, Номер 171, С. 107715 - 107715

Tire wear particles (TWPs) enter road surface with the friction between tires and surfaces. Under volatilization, leaching, transformation action on TWPs by sunlight rain, tire additives are released into urban water systems, such as rainfall runoff, wastewater treatment plants (WWTPs), receiving waters, drinking plant (DWTP). In this study, we investigated occurrence of 23 their products in system Pearl River Delta region, South China. Nineteen target compounds were detected 1,3-Diphenylguanidine (DPG) showing highest maximum concentration 58780 ng/L. Benzothiazole its at frequency 100 % total concentrations 480-42160 The antioxidant derivative N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine-quinone (6PPD-Q) was also up to 1562 ng/L, which considerably higher than that parent compound 6PPD (the 7.52 ng/L). Eleven 8 WWTPs influents effluents, respectively, removal rates - 62-100 %. Seventeen Zhujiang Dongjiang rivers, while 9 sources DWTP samples.

Concentrations of tire wear microplastics and other traffic-derived non-exhaust particles in the road environment

Environment International, Год журнала: 2022, Номер 170, С. 107618 - 107618

Tire wear particles (TWP) are assumed to be one of the major sources microplastic pollution environment. However, many previously published studies based on theoretical estimations rather than field measurements. To increase knowledge regarding actual environmental concentrations, samples were collected and analyzed from different matrices in a rural highway environment characterize quantify TWP other traffic-derived non-exhaust particles. The sampled included road dust (from kerb in-between wheeltracks), runoff (water sediment), air. In addition, airborne deposition was determined transect with increasing distance road. Two sieved size fractions (2-20 µm 20-125 µm) by automated Scanning Electron Microscopy/Energy Dispersive X-ray spectroscopy (SEM/EDX) single particle analysis classified machine learning algorithm into following subclasses: TWP, bitumen (BiWP), markings, reflecting glass beads, metals, minerals, biogenic/organic relative number concentrations (%) showed that contained highest proportion (up 38 %). share tended higher BiWP. seasonal BiWP observed coarse (20-125 during winter, most likely studded tire use. concentration subclasses within PM80-1 decreases road, evidencing traffic as main emission source. results confirm surrounding contain microplastics both fractions. finer fraction dominated (by mass, volume, number) all sample matrices. These have high potential transported water air far away source can contribute inhalable (PM10) This highlights importance including also future investigations.

Environmental Science & Technology Letters, Год журнала: 2022, Номер 9(5), С. 413 - 419

Опубликована: Апрель 12, 2022

Transformation products (TPs) originating within tire tread wear particles (TWPs) are likely pervasive contaminants of roadway environments although their formation, fate, and risks poorly characterized. Here, we investigated TP formation occurring during heterogeneous reaction gas-phase ozone with the common rubber antioxidant 6PPD (N-(1,3-dimethylbutyl)-N′-phenyl-p-phenylenediamine); exposures included both pure compound TWP rubbers. Oxidative transformation occurred ozonation (∼360 ppbv), up to 81% mass reacting over 6 h. Conversion 6PPD-quinone (6PPDQ)─a recently reported highly toxic TP─was confirmed at a 9.7% molar yield for 0.95% present TWPs, representing minima these time scales conditions. Leveraging high-resolution spectrometry, identified 19 probable 6PPD-derived TPs in ozonated samples, underscoring diverse from this antioxidant. By screening environmental nine were detected runoff. The data confirm that when antioxidants react ozone, as intended, they form release various surrounding environments.

Airborne microplastic particle concentrations and characterization in indoor urban microenvironments

Environmental Pollution, Год журнала: 2022, Номер 308, С. 119707 - 119707

Опубликована: Июль 5, 2022

Airborne microplastics (MPs) have recently drawn the attention of scientific community due to their possible human inhalation risk. Indoor environments are relevance as people spend about 90% time indoors. This study evaluated MPs concentrations in three indoor environments: houses, public transport and working places, which representative urban life. Sampling involved collection airborne particulate matter on nylon 20 μm pore size filters. Samples were first visually inspected, particles characterized (colour, length or area). Polymer identification was performed through μFTIR analysis. Working conditions controlled guarantee quality assurance avoid background contamination. Limits detection, recovery tests repeatability with home-made polyethylene (PE), polypropylene (PP), polystyrene (PS) standards. The highest average MP found buses (17.3 ± 2.4 MPs/m3) followed by 5.8 1.9 MPs/m3 subways, 4.8 1.6 4.2 workplaces. Polyamide, PA (51%), polyester PES (48%) PP (1%) polymers identified most common personal care products synthetic textiles. Most these below 100 for both fibres (64 8%) fragments (78 11%). frequency our decreased increasing size, points potential an hazard.
