ClearA comparative analysis of the chemical composition and biofilm formation on tire wear particles from six different tire types
Researchers analyzed the chemical composition and biofilm communities forming on tire-wear particles compared to other microplastic types, finding that tire wear particles support distinct microbial assemblages. The unique surface chemistry of tire wear particles may promote the attachment of pathogens and toxin-producing microorganisms.
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.
Environmental occurrence, fate, impact, and potential solution of tire microplastics: Similarities and differences with tire wear particles
This review examines tire microplastics, one of the most abundant types of microplastics in the environment, which come from tire wear on roads, recycled tire rubber, and tire repair dust. These particles carry a complex mix of chemicals including heavy metals and organic pollutants that can harm aquatic and soil organisms. Since tire microplastics end up in waterways and soil near roads, they represent a significant but often overlooked source of human microplastic exposure.
PET particles raise microbiological concerns for human health while tyre wear microplastic particles potentially affect ecosystem services in waters
Researchers tested how PET particles and tire wear microplastics affect microbial communities in freshwater systems. They found that PET particles promoted the growth of potential human pathogens, while tire wear particles altered the broader microbial community composition relevant to ecosystem functions. The study suggests these two common types of microplastics pose distinct but significant risks to water quality and public health.
Longitudinal and vertical distribution pattern of tire wear particles in an urban bioswale
Researchers examined the longitudinal and vertical distribution of tire wear particles (TWPs) within an urban bioswale — a type of sustainable urban drainage system — to assess how effectively this infrastructure captures and retains road runoff-derived microplastics. The study found that TWPs were distributed throughout the bioswale profile, demonstrating both retention capacity and potential for subsurface accumulation of these chemically complex road-derived microplastics.
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.
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.
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.

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.
Occurrence, fate, and ecological impacts of microplastics in soil: a comparative analysis of conventional, biodegradable microplastics, and tire wear particles
This comparative review examined the occurrence and fate of microplastics in soil across studies on conventional MPs, biodegradable MPs, and tire wear particles, finding that current knowledge based on conventional MPs may not apply to alternative types. Biodegradable MPs and TWPs showed distinct degradation rates, transport behaviors, and ecotoxicological profiles that require separate assessment.
Identification, classification and quantification of microplastics in road dust and stormwater
Researchers identified and quantified microplastics in road dust and stormwater, finding significantly higher concentrations in industrial areas compared to residential zones, with tire wear particles and polyethylene fragments being the most common types.
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.
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.
Tire wear particles in aquatic environments: A systematic review of sources, detection, distribution, and toxicological impacts
This systematic review examined tire wear particles — a type of microplastic created as tires wear down on roads — as an emerging water pollutant. These particles wash into rivers and oceans through stormwater runoff and contain toxic chemicals that harm aquatic organisms. Since tire wear is one of the largest sources of microplastic pollution, this is relevant to anyone living near roads or consuming seafood.
Adsorption of emerging micropollutants on tire wear particles
Researchers examined how tire wear particles (TWP) adsorb two common water pollutants—bisphenol A and 1H-benzotriazole—and how aging processes (photo, chemical, biological) affect that adsorption. TWP showed stronger adsorption of bisphenol A than benzotriazole, and aging altered sorption behavior, highlighting TWP as a significant carrier of micropollutants in aquatic environments.
Cotransport of 6PPD-Q and pristine/aged microplastics in porous media: An insight based on transport forms and mechanisms
Researchers investigated the cotransport of tire-derived chemical 6PPD-Q with pristine and aged microplastics through porous media. The study found that pristine microplastics adsorbed more 6PPD-Q than aged ones due to hydrophobic interactions, and that microplastics can facilitate the transport of this toxic tire rubber compound through soil and groundwater systems.
Priorities to inform research on tire particles and their chemical leachates: A collective perspective.
An international interdisciplinary network of researchers identified priority research areas for understanding the ecological impacts of tire particles and their chemical leachates — a rapidly growing area of concern given that tire wear particles are one of the largest sources of microplastics in urban runoff. The priorities span toxicology, exposure assessment, and regulatory relevance.
Comparison of lead adsorption on the aged conventional microplastics, biodegradable microplastics and environmentally-relevant tire wear particles
Researchers compared how different types of aged microplastics, including tire wear particles and biodegradable polylactic acid, adsorb the heavy metal lead from water. The study found that aging significantly increased adsorption capacity across all types, with tire wear particles showing the highest lead uptake, and that environmental factors like humic acid concentration had complex effects on the adsorption process.

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.

Researchers conducted the first comprehensive environmental risk assessment of tire wear microplastic particles and their associated chemical pollutants in European road runoff. They found that tire wear particles and several related chemicals pose measurable risks to organisms in surface water and sediment. The study suggests that tire wear is a significant but often overlooked source of microplastic pollution with real consequences for aquatic ecosystems.
Micron-size tire tread particles leach organic compounds at higher rates than centimeter-size particles: Compound identification and profile comparison
Researchers compared how micro-sized and centimeter-sized tire tread particles release chemicals into water and found that smaller particles leached organic compounds at substantially higher rates due to their greater surface area. The chemical analysis revealed hundreds of distinct compounds in the leachate, many of which have not been previously identified from tire wear. The findings suggest that as tire particles break down into smaller pieces in the environment, they become increasingly potent sources of chemical pollution in waterways.
Mitigating tire wear particles and tire additive chemicals in stormwater with permeable pavements
Researchers tested whether permeable pavements could filter out tire wear particles and their toxic chemicals, including 6PPD-quinone, which is lethal to salmon. The pavements captured over 96% of tire particles and removed 52-100% of the toxic 6PPD-quinone from stormwater runoff. Since tire wear is a major source of microplastic pollution in urban waterways, permeable pavements could be a practical way to reduce both microplastic contamination and chemical toxicity in streams and rivers.
