ClearMicroplastics in gully pot sediment in urban areas: Presence, quantities and characteristics
Researchers analyzed sediment from 29 urban gully pots — the roadside drains that funnel stormwater into sewer pipes — and found concentrations of up to 10,600 microplastic particles per 100g of sediment, with tire wear particles making up roughly a third. The study shows gully pots act as temporary traps for microplastics before they flush into waterways, and that maintaining and cleaning them could reduce the flow of microplastics into rivers and the ocean. This is a practical, infrastructure-based intervention point for cutting urban microplastic pollution.
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.
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.
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.
Is road pavement wear a source of microplastics in stormwater runoff?
This study investigated whether road pavement wear is a measurable source of microplastics in stormwater runoff, distinct from the better-characterized tire wear contribution. Pavement-derived particles were identified in stormwater samples, confirming that road surface material itself contributes to microplastic loading in urban runoff alongside tire wear and other 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.

Researchers developed a conceptual framework to estimate emissions of tire and road wear particles (TRWPs) into surface water, identifying them as a dominant source of microplastic contamination in freshwater environments globally.

Researchers examined tire and road wear particle (TRWP) contamination in infiltration pond sediments, characterizing their occurrence, spatial variability, size distribution, and correlation with heavy metals to assess the pollution dynamics of these road-derived particles in urban drainage systems.
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.
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.
Microplastics and tyre wear particles in urban runoff from different urban surfaces
Researchers measured microplastics and tire wear particles in stormwater runoff from roads, parking lots, and rooftops in Sweden. They found that road runoff carried the highest concentrations by far, with large variations between rainfall events. The findings highlight urban roads as a major source of microplastic pollution entering nearby waterways through stormwater.

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.
Urban wash-off of tire wear particles
Researchers used a rainfall simulator to study how tire wear particles, an important class of microplastics, are washed off road surfaces during storm events. They found that low surface roughness, high rainfall intensity, and low slope produced the fastest and most complete mobilization of tire wear particles. The study reveals that larger tire particles moved faster than smaller ones, and flow depth was the most important factor governing wash-off behavior.
Microplastics and Tire Wear Particles in Urban Stormwater: Abundance, Characteristics, and Potential Mitigation Strategies
Researchers measured microplastic concentrations in urban stormwater and found levels ranging from about 4 to 59 particles per liter, with tire wear particles making up roughly 95% of all particles detected. Microlitter capture devices reduced microplastic loads by 35 to 88%, and constructed wetlands provided additional removal. The study suggests that targeted stormwater treatment infrastructure could meaningfully reduce the flow of microplastics into rivers and coastal waters.

Removal of tire wear from road runoff
This doctoral thesis developed sampling systems to measure tire-wear particle emissions at urban hotspots and tested decentralized filter solutions to capture these particles before they enter surface waters via road runoff.
