Relevance of tyre wear particles to the total content of microplastics transported by runoff in a high-imperviousness and intense vehicle traffic urban area.
Researchers characterized microplastics and tire wear particles (TWPs) transported by urban stormwater runoff in a highly impervious catchment, finding that TWPs made up a substantial fraction of the total microplastic load in sediments of a stormwater detention reservoir. The study underscores the contribution of road traffic to microplastic pollution entering waterways.
The transport of tyre wear particles in rivers, with a focus on settling and resuspension
Researchers investigated the transport dynamics of tyre and road wear particles (TRWPs) in river systems, with particular focus on settling and resuspension processes in aquatic environments, and explored pathways toward groundwater, addressing a gap in understanding TRWP fate in the environment.

Microplastics from tyre and road wear A literature review
This literature review examines microplastics generated from tire and road wear, identifying road traffic as a significant but often overlooked source of plastic pollution in urban runoff and waterways. The authors assess what is known about tire particle composition, environmental fate, and potential ecological effects.
Assessment of fine and coarse tyre wear particles along a highway stormwater system and in receiving waters: Occurrence and transport
Researchers tracked tire wear particles through a highway stormwater drainage system in Sweden and found contamination at nearly every sampling point, with concentrations reaching up to 17 milligrams per liter in water. A significant portion of the particles were very small, in the 1.6 to 20 micrometer range, which are harder to filter out and more likely to travel long distances. The study highlights that tire wear is a major and often overlooked source of microplastic pollution reaching waterways.
Tyre wear particles: an abundant yet widely unreported microplastic?
Researchers collected tire wear particles from roadside drains and natural environments near a major UK road, finding that these particles are abundant and widespread yet frequently undetected in environmental monitoring, suggesting tyre wear is a major but under-reported microplastic source.
Towards a model for road runoff infiltration management
Researchers analyzed over 2,400 chemical micropollutants in stormwater runoff from roads, tracking how well infiltration ponds — engineered soil systems — trapped these contaminants before they reached groundwater. Sand in the infiltration pond retained 86% of micropollutant abundance, and the study proposes a practical model linking soil properties to pollutant trapping efficiency.
Characterization of tire and road wear microplastic particle contamination in a road tunnel: From surface to release
Researchers characterized tire and road wear particle distributions across multiple compartments of a road tunnel including road surfaces, gully pots, and wash water, finding the highest concentrations in side bank surface deposits and gully pots at the tunnel inlet. Sedimentation treatment retained only 63% of tire and road wear particles from wash water, highlighting the need for improved treatment to prevent environmental release.
Tyre and road wear particles from source to sea
Researchers traced tyre and road wear particles (TRWP) — tiny rubber fragments shed when vehicles brake and turn — from urban roads into marine sediments, finding that softer tyres with more natural rubber shed more particles and that TRWP concentrations drop sharply with distance from cities. Unlike lighter microplastics that drift widely, TRWP sink quickly and accumulate near urban coastlines, threatening nearshore sediment ecosystems.
The transport of tyre wear particles in rivers, with a focus on settling and resuspension
Researchers investigated the transport, settling, and resuspension behavior of tyre and road wear particles (TRWPs) in river systems compared to conventional microplastics, presenting initial characterization data on TRWP density and zeta potential and conducting mesocosm flume experiments to test hypotheses about their differential environmental fate.
Tire road wear particles, microplastics and metals in sediment of stormwater detention basins: co-occurrence and ecological risk assessment
Researchers analyzed sediment from eleven stormwater detention basins in a French metropolitan area to assess contamination by tire wear particles, microplastics, and metals. They found that tire wear particles were consistently more abundant than microplastics across all sites, with industrial areas showing the highest levels at over 20,000 mg per kilogram. The study revealed a significant positive correlation between urban-related metals and both tire wear particles and microplastics, indicating these pollutants share common sources.
Tire Wear Monitoring Approach for Hotspot Identification in Road Deposited Sediments from a Metropolitan City in Germany
Researchers developed a systematic road-sampling approach to identify urban hotspots for tire-and-road wear particles (TRWP) — a major category of microplastic pollution — by sweeping road-deposited sediments at six inner-city monitoring sites. Curves and traffic-light zones accumulated 8x and 3x more styrene-butadiene rubber (a TRWP marker) than straight road sections, respectively. Since tire wear is one of the largest sources of microplastics entering waterways via road runoff, this hotspot mapping method can inform targeted mitigation measures.
Realistic evaluation of tire wear particle emissions and their driving factors on different road types
This study measured tire wear particle (TWP) emissions under realistic driving conditions on different road types and identified the key driving factors affecting emission rates. Tire wear particles are a major category of microplastic pollution in road runoff, and this data is needed to estimate their contribution to environmental contamination.
Identification of tire and road wear particles in artificial water bodies in Japan
Tire and road wear particles (TRWPs) — tiny fragments shed when rubber tires contact road surfaces — are a major but often overlooked source of microplastic pollution. Researchers found TRWPs in all four urban regions of Japan they examined, including artificial ponds and water features, with concentrations ranging widely by location and showing signs of weathering over time. Because these artificial water bodies act as retention zones that collect and concentrate road runoff, they may be quietly accumulating tire-derived microplastics that then affect aquatic life.
Retention of microplastics and tyre wear particles in stormwater ponds
Researchers analyzed stormwater retention ponds to assess their effectiveness at capturing microplastics and tire wear particles from urban runoff. They found microplastics in all water samples and significantly higher concentrations in pond sediments, suggesting that the ponds do retain a portion of these pollutants. The study indicates that while stormwater ponds offer some mitigation, their long-term performance for trapping emerging contaminants like microplastics needs further evaluation.

Potential deterioration of chemical water quality due to trace metal adsorption onto tire and road wear particles – Environmentally representative experiments
Researchers studied how tire and road wear particles affect water quality by adsorbing trace metals from the environment. They found that these particles, which constitute a significant fraction of microplastic emissions, can adsorb metals like zinc and copper from water under realistic environmental conditions. The findings indicate that tire wear particles may worsen chemical water quality in surface waters by acting as carriers and concentrators of toxic metals.
