ClearBioswales as potential sinks for tyre wear particle pollution
Researchers investigated the role of bioswale green infrastructure in capturing tyre wear particle microplastics from road runoff, presenting data from bioswales constructed in 2010 and quantifying their effectiveness as sinks for tyre-derived microplastic pollution.
Stock and vertical distribution of microplastics and tire and road wear particles into the soils of a high-traffic roadside biofiltration swale
Researchers quantified microplastics and tire and road wear particles in soil profiles of a highway-adjacent biofiltration swale in France, sampling at multiple depths. TRWP concentrations were highest near the road surface and declined with depth and distance, but particles were detected down to 30 cm, indicating that these roadside green infrastructure features accumulate and partially retain traffic-derived microplastics.

Researchers investigated the infiltration of microplastics and tyre wear particles into soil along a roadside biofiltration swale, assessing the extent to which these particles migrate from the road surface into subsurface soils under real-world conditions.
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 difference between tire wear particles and polyethylene microplastics in stormwater filtration systems: Perspectives from aging process, conventional pollutants removal and microbial communities
Researchers compared how tire wear particles and polyethylene microplastics behave in stormwater filtration systems used to treat urban runoff. They found that tire wear particles leached more toxic chemicals and supported different microbial communities than conventional microplastics, leading to distinct effects on pollutant removal. The study highlights that tire wear particles deserve separate consideration from other microplastics when designing stormwater treatment infrastructure.
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.

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.
Permeable pavements: A possible sink for tyre wear particles and other microplastics?
Researchers sampled approximately 100 kg of particulate material from seven roads and parking lots to analyze microplastic content including tire wear particles. The study found that tire wear constituted the dominant fraction of microplastics at 0.09% of dry mass, with polypropylene as the most common non-tire plastic type, and that permeable pavements may act as sinks trapping these particles before they reach waterways.
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.
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.
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.
Types and concentrations of tire wear particles (TWPs) in road dust generated in slow lanes.
Road dust samples collected near traffic lights contained tire wear particles (TWPs), with the concentration and size distribution varying by location and traffic direction. Tire wear is one of the largest sources of microplastic pollution in urban environments, and these particles are carried into waterways by stormwater runoff.
Effect of tire wear particle accumulation on nitrogen removal and greenhouse gases abatement in bioretention systems: Soil characteristics, microbial community, and functional genes
This study found that tire wear particles, a major type of microplastic in road runoff, significantly reduced the ability of bioretention systems (rain garden-like structures) to remove nitrogen from stormwater. The tire particles changed the soil's microbial communities, reducing populations of bacteria that process nitrogen and altering greenhouse gas emissions. Since bioretention systems are widely used to treat urban stormwater before it enters waterways, this research shows that tire-derived microplastics can undermine water treatment efforts.
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. Tire wear is one of the largest single sources of microplastic pollution, and practical, scalable roadside filtration could meaningfully reduce the amount reaching aquatic ecosystems.

Pavement wear generates microplastics in stormwater runoff
Researchers conducted a two-year field study showing that pavement wear is a distinct and previously underappreciated source of microplastics in urban stormwater, separate from tire wear. They found that asphalt pavement was most susceptible to degradation in the field, while recycled rubber pavers released the most microplastics in lab testing. The study emphasizes the need to consider microplastic generation during pavement material selection and urban infrastructure planning.
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 particles in different water environments: occurrence, behavior, and biological effects—a review and perspectives
This review examines tire wear particles, a major but often overlooked source of microplastics in water environments. Tire particles release toxic chemicals as they break down in water and can harm aquatic organisms, but most research has focused only on the chemical leachate rather than the particles themselves. Since tire wear contributes a large share of total microplastic pollution, understanding its full impact on water ecosystems and the food chain is important for human health.
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.
