Occurrence, Emission, and Transport of Tire and Road Wear Particles across Four Environmental Compartments along Ring Road Networks in Beijing

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: unknown

Published: Dec. 16, 2024

Tire and road wear particles (TRWPs) are an appreciable source of microplastics (MPs); however, knowledge their large-scale occurrence mass flux based on robust sampling quantification is limited. Herein, the first city-wide survey TRWPs across environmental compartments (road dust, snowbank, water, sediment from rivers lakes) along four ring roads (beltways) in Beijing was performed. TRWP concentrations (n = 74) were quantified using bonded-sulfur as a marker to reveal spatial distributions adopted establish framework estimating emission factors (EFs) generation remote atmospheric, terrestrial, aquatic transport.

This study provides new insights into fate TRWPs.

Snow dumping station – A considerable source of tyre wear, microplastics, and heavy metal pollution

Environment International, Journal Year: 2024, Volume and Issue: 188, P. 108782 - 108782

Snow dumping stations can be a hotspots for pollutants to water resources. However, little is known about the amount of microplastics including tyre wear particles transported this way. This study investigated and metals in snow from four Riga, Latvia, remote site (Gauja National Park), roof top Riga. Microplastics other than were identified with Attenuated Total Reflection Fourier Transform Infrared (ATR-FTIR) (>500 µm) focal plane array based micro-Fourier (FPA-µFTIR) imaging (10–500 µm), by Pyrolysis Gas Chromatography-Mass Spectroscopy (Py-GC–MS), total Inductively Coupled Plasma Optical Emission (ICP-OES). detected FTIR quantified particle counts their mass estimated, while mass. The concentrations varied substantially, highest levels urban areas. Microplastic measured ranged between 26 2549 L−1 melted corresponding estimated 19–573 µg/L. Tyre not at two reference sites, sites held 44–3026 Metal several orders magnitude example sodium range 0.45–819.54 mg/L cadmium 0.05–0.94 Correlating microplastic metal content showed weak moderate correlation. particles, however, correlated strongly many metals. that hold considerable amounts these pollutants, which upon melting release meltwater aquatic environment could impact receiving waters.

Microplastics and Tyre Wear Particles in Urban Runoff from Different Land Use Types

Published: Jan. 1, 2024

Urban runoff is an important conveyor of microplastics (MPs) and tyre wear particles (TWP) to receiving waters. However, knowledge contributions by land use type/activities currently limited. To address this gap, samples were collected simultaneously during three rainfall events at locations with different surfaces (parking lot, road roof). The occurrence MPs (by number mass) TWP (mass) determined using µ-FTIR Pyr-GC/MS, respectively. found all sites in events, large variations between sites. highest concentrations (number) followed parking lot roof runoff. mass did not follow the same pattern generally highlighting importance reporting data as both particle numbers derive a complete overview behaviour. Polypropylene, polyethylene, polyester accounted, on average, for 99% MP polymers number) common sources, including traffic (vehicle tear) littering. <75 µm fraction contributed >50% total runoff, >58% >90%
