Tire-additive chemicals and their derivatives in urban road dust: Spatial distributions, exposures, and associations with tire and road wear particles
Researchers measured tire-related chemicals and tire wear particles in road dust from Hong Kong and Berlin, finding that highway dust contained up to five times more contamination than other road types. Several of these tire-derived chemicals are linked to health risks including hormone disruption and cardiovascular problems, and the study found that people living near busy roads face higher exposure through accidental dust ingestion.

Tyre Wear Particles in the Environment: Sources, Toxicity, and Remediation Approaches
This review examines tire wear particles, which account for a major share of global microplastic pollution with 1.3 million metric tons released annually in Europe alone. These rubber-based particles contain heavy metals and toxic organic chemicals that contaminate air, water, and soil, and human exposure occurs through inhaling dust, eating contaminated food, and drinking water, raising concerns about respiratory, cardiovascular, and cancer risks.
Micro- and nano-plastics (MNPs) in urban air: polymer composition, interactions and inhalation risk
Researchers characterized airborne micro- and nanoplastics in urban air using pyrolysis gas chromatography-mass spectrometry on size-fractionated aerosol samples. The study found total concentrations averaging 0.6 micrograms per cubic meter, with tire wear particles as a dominant source, highlighting an underestimated threat to urban air quality and human respiratory 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.
Investigation of physical and chemical properties of particulate matter caused by vehicle tire wear
Researchers characterized the physical and chemical properties of submicron tire wear particles generated from vehicle use on roadways. Using advanced analytical techniques, they identified the elemental composition and morphological structure of these particles, finding notable concentrations of metals and heavy metals. The study highlights that tire wear particles are a significant source of microplastic and chemical pollution with potential implications for human health and the environment.
Tracks of travel: unveiling tire particle concentrations in Swiss cantonal road soils
Researchers quantified tire wear particle concentrations in roadside soils along fifteen Swiss cantonal roads with relatively low traffic volumes. They found average concentrations of 111,000 particles per kilogram of dry soil, with particle counts and sizes decreasing with increasing distance from the road. The study also found positive relationships between tire wear particle numbers and associated pollutants like polycyclic aromatic hydrocarbons and trace metals.
Chemical Leaching from Tire Wear Particles with Various Treadwear Ratings
Researchers investigated how tire treadwear ratings affect chemical leaching from tire wear particles, finding that benzothiazole compounds leached at different rates depending on tire type, with an additional derivative (2-mercaptobenzothiazole) detected by high-resolution mass spectrometry. The findings suggest that using benzothiazole alone as a quantification marker for tire wear particles can lead to inaccurate estimates of environmental contamination.
Tracking the source: First evidence of Benzothiazoles in outdoor airport aerosol
Researchers detected chemical compounds called benzothiazoles — used as additives in rubber tires and released when tires wear down — for the first time in outdoor air samples collected at Milan's Linate airport, linking them to aircraft tire abrasion during landings and takeoffs. The findings identify airports as an overlooked source of tire wear microplastic particles and associated toxic chemicals in the atmosphere.
A review of rubber tyre derived micro- and nanoplastics: fate, impact and risks
This systematic review examines microplastics generated from rubber tire wear, which are a major but often overlooked source of microplastic pollution. Tire particles spread through air, stormwater, and wastewater to contaminate both land and water. This is an important human health concern because tire-derived microplastics contain toxic chemicals and are found in the air people breathe and the water they drink.
Concentrations of tire wear microplastics and other traffic-derived non-exhaust particles in the road environment
Researchers measured actual environmental concentrations of tire wear microplastics and other traffic-derived non-exhaust particles in a rural highway setting, providing field-based data to complement the theoretical estimates that dominate current literature.
About the variability of tire and road wear marker components in air: from emissions to atmospheric deposition
Scientists developed a new method to track tiny particles that come from car tires wearing down on roads, which are now recognized as one of the biggest sources of microplastic pollution worldwide. They found these tire particles can travel far from roads through the air and change into different chemicals, including some that may be harmful. This matters because these airborne tire particles could pose risks to human health and the environment, but we're just starting to understand how much is actually in the air we breathe.
Chemical composition and potential health risks of tire and road wear microplastics from light-duty vehicles in an urban tunnel in China
Researchers collected tire and road wear microplastics from a traffic tunnel in China and analyzed their chemical makeup, finding high levels of phthalates, rubber compounds, and other potentially harmful substances. Concentrations varied by time of day, peaking during rush hours when traffic was heaviest. The study suggests that tire-derived microplastics carry a cocktail of chemicals that could pose health risks to people who live or work near busy roads.
Explorations of tire and road wear microplastics in road dust PM2.5 at eight megacities in China
Researchers measured tire and road wear microplastics in road dust from eight major Chinese cities. They found the highest concentrations in northern cities like Lanzhou and Xi'an, likely due to drier conditions increasing road friction, with levels ranging from 86 to 175 micrograms per gram. The study also found correlations between these microplastics and markers of cellular damage, suggesting potential health implications from exposure to tire-derived particles in urban road dust.
Comparison of traffic-related micro- and nanoplastic concentrations at three urban locations
Researchers measured airborne tire and road wear particles (microplastics shed from vehicle tires) at a busy urban road, a highway, and a park, finding rubber particle concentrations were 2-5 times higher near traffic compared to the park, with levels closely tracking other traffic pollutants like black carbon.
An in vitro comparison of the toxicological profiles of ground tire particles (TP) and actual tire and road wear particles (TRWP) emissions
Researchers compared the lung toxicity of ground tire particles and real tire-and-road wear particles collected from traffic, finding that both triggered inflammation in alveolar immune cells (macrophages) but neither caused significant cell death or oxidative damage. Real road particles prompted slightly more inflammation than pure tire rubber, suggesting the rubber itself drives most of the lung harm from tire pollution.

Micro and Nano Pollutants from Tires and Car Brakes Generated in Winter Season in the Poznan City Urban Environment
Tire and brake pad wear from vehicles releases rubber particles and metal-oxide pollutants at the micro and nanoscale into the urban environment, with snow deposits in Poznan, Poland found to contain rubber residues smaller than 2 micrometers. These non-exhaust traffic emissions represent a significant and often overlooked pathway for microplastic and metal pollution in cities, with implications for urban air, soil, and water quality.
