ClearMicroplastics 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.
Microplastic and tyre wear particles at a highway: a case study from Norway
Researchers monitored microplastics and tire wear particles (tiny rubber fragments shed by vehicles) in air, road runoff, and road dust along a busy Norwegian highway, finding the highest concentrations in road dust and the lowest in air. The study demonstrates that traffic is a major source of microplastic pollution across multiple environmental pathways.
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.
Comparison of traffic-related micro- and nanoplastic concentrations at three urban locations

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.
Modelled atmospheric concentration of tyre wear in an urban environment
Researchers modeled airborne concentrations of tire wear particles — tiny plastic-containing fragments released when vehicle tires rub against road surfaces — across Stockholm, finding that these microplastic particles are widespread in cities and make up 4–6% of total air particle pollution, with concentrations highest near busy highways and in narrow street canyons.
What is known and unknown concerning microplastics from tyre wear?
This review synthesizes current knowledge on tyre wear particles (TWPs) as a major source of road-traffic microplastics, covering how particle generation, transport pathways, and environmental fate depend on tyre composition, road characteristics, and weather. A key finding is that while TWPs can be identified in environmental samples, quantifying them precisely remains difficult and expensive—a gap that must be closed to accurately assess human and ecological exposure.
Mass concentrations of common microplastics and tire wear rubbers in urban air
Researchers measured mass concentrations of common microplastics and tire wear rubber particles in urban ambient air, providing quantitative data for inhalation exposure assessment. Tire wear rubber dominated the airborne particle mass in traffic-influenced areas, exceeding concentrations of synthetic polymer microplastics.
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.
Pollution from Transport: Detection of Tyre Particles in Environmental Samples
This study reviews tyre wear particles as a major but underestimated source of microplastic pollution from road transport, describing methods for detecting these particles in environmental samples including road dust, waterways, and soils. The authors call for greater regulatory attention to tyre-derived emissions alongside other transport-related pollutants.
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.
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.
Measures to reduce the spread of microplastic particles from tyre wear : On vehicles, on the road and in the roadside environment
Researchers reviewed measures to reduce the spread of microplastic particles from tyre wear at the vehicle, road, and roadside environment levels, examining the transport pathways via air, water, and snow and the risks these persistent, potentially toxic particles pose to ecosystems and human health.
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.
