Researchers measured the terminal settling velocities of tyre and road wear particles (TRWP) from a road simulator and highway tunnel across different density and size fractions, providing the first empirical settling velocity data for these particles to support modeling of their transport in aquatic environments.
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.
Seasonal variation in characteristics of wear microparticles of high density (> 1.8 g cm−3) produced on road
By analyzing road dust across seasons, this study characterized the types and quantities of high-density wear particles (denser than 1.8 g/cm³) produced by traffic, including tire rubber, road paint, glass beads, and plastic particles, with winter generating the most. Dense particles settle out of water quickly, meaning they concentrate in nearby river sediments and could serve as useful tracers for tracking road-sourced pollution.

Researchers measured tire wear particle (TWP) concentrations in gully pot sediments, developing analytical methods to quantify this major microplastic source in road runoff as it enters urban drainage systems before reaching the broader environment.
Characterization of Particles in Road Surface Sediments for Analyzing Runoff Behavior of Microplastics
Researchers characterized physical properties — density, shape, and material composition — of particles in road surface sediments and stormwater catchpit deposits in Japan using density-gradient separation, image analysis, and ATR-FTIR, finding that synthetic polymers comprised 40-50% of all particles and were concentrated in high-density fractions with Feret diameters of 500-800 micrometers.
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.
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.
Particle-Associated Contaminant Transport in Rivers during High Discharge Events
Researchers examined suspended river sediments during high discharge events for the presence of anthropogenic particles including microplastics and tyre wear particles, as well as their co-transport with organic pollutants including PFAS and polycyclic aromatic hydrocarbons, in an urbanizing catchment context.
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.
Classification and Characterization of Tire-Road Wear Particles in Road Dust by Density
Tire-road wear particles were classified and characterized by density using road dust from an asphalt pavement, allowing separation of tire tread-derived particles from road surface and mineral components. The density-based classification approach improves the accuracy of tire wear particle quantification in environmental monitoring studies.
Distribution and accumulation patterns of tire-derived particles in coastal and lake sediments
Tire and road wear particles (TRWP) — tiny fragments shed every time a vehicle brakes or turns — are among the largest sources of microplastics globally, and this study found them in sediments across 32 of 36 sampling sites in Japanese lakes and coastal waters. Critically, at 30 of those 36 sites, concentrations exceeded levels considered safe for aquatic ecosystems, suggesting widespread ecological risk. The research also found that TRWP tend to travel with fine soil particles and organic matter, offering clues about how these pollutants disperse through river systems and settle in aquatic environments.
Occurrence of tire and bitumen wear microplastics on urban streets and in sweepsand and washwater
Tire tread wear and bitumen particles were the dominant anthropogenic microplastics found on urban roads and in sweeping waste and stormwater in a Norwegian study, with concentrations up to 2,561 particles per liter in road dust samples. Street sweeping removed significant quantities of these particles, and sodium iodide density separation proved effective for their analytical isolation.
Tire wear particles in the aquatic environment - A review on generation, analysis, occurrence, fate and effects
Researchers reviewed available science on tire wear particles (TWP) — tiny fragments shed from tires during driving — finding that Europe alone generates over 1.3 million tonnes per year, but critical data on environmental concentrations, transport to waterways, and aquatic toxicity remain too limited for robust 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.
