ClearA comparative analysis of the chemical composition and biofilm formation on tire wear particles from six different tire types
Researchers compared the chemical composition and biofilm characteristics of tire wear particles collected from different vehicle types and road conditions, examining how these variables affect toxin and pathogen attachment. Tire wear particle composition varied with source, and surface properties influenced the attachment of microorganisms and contaminants, affecting their hazard potential.
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.
“Tire plastisphere” in aquatic ecosystems: Biofilms colonizing on tire particles exhibiting a distinct community structure and assembly compared to conventional plastisphere
This study examined biofilm communities (the "tire plastisphere") forming on tire particles in aquatic ecosystems, characterizing the microorganisms that colonize rubber particles and assessing whether the plastisphere community differs from surrounding water or sediment microbiomes. Tire particles hosted distinct biofilm communities enriched in potentially pathogenic and hydrocarbon-degrading bacteria.
Bacterial community colonization on tire microplastics in typical urban water environments and associated impacting factors
Researchers used 16S rDNA high-throughput sequencing to characterize bacterial community dynamics colonizing tire microplastics from three different tire brands and sizes in two urban water environments, including a constructed wetland influent pond. The study identified how tire microplastics support distinct and potentially harmful bacterial communities influenced by environmental conditions.
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.
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.
Tire wear particles: An emerging threat to soil health
This review synthesizes knowledge about tire wear particles — a major but often overlooked source of microplastic-like pollutants — in soil ecosystems. Tire wear particles contain toxic metals and organic compounds that harm soil microbes, invertebrates, and plants, but most research to date has focused on aquatic systems rather than soils.
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.
Tire Wear Particles and Their Role in Microplastic Pollution
This review synthesized research on tire wear particles (TWPs) as a major but often overlooked source of microplastic pollution, contributing roughly six million tonnes annually. TWPs spread into soil, rivers, and oceans, where they carry toxic chemicals including heavy metals and PAHs, posing risks to wildlife and potentially entering the human food chain.
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.
Tire wear particles: An emerging threat to soil health
This review examines tire wear particles as an emerging source of soil contamination, finding that these microplastics contain a complex mixture of rubber, metals, and organic chemicals that can harm soil organisms. Researchers highlight that most current studies focus on individual species, which may underestimate the cascading effects on entire soil ecosystems. The study warns that tire wear particles could alter essential soil processes and ecosystem services, representing a significant but underappreciated threat to soil health.
Methods for laboratory-generation and physico-chemical characterisation of tyre wear particles
Researchers developed a lab method to generate tire wear particles using a friction machine and then identified a suite of chemical compounds that could serve as reliable markers for detecting these particles in environmental samples. Tire wear is one of the largest single sources of microplastic pollution globally, yet quantifying it in the environment has been hampered by the lack of agreed marker compounds. This work lays groundwork for standardized monitoring of tire particle pollution in soils and waterways.
Succession-driven potential functional shifts in microbial communities in the tire-plastisphere: Comparison of pristine and scrap tire
Researchers incubated pristine and scrap tire microplastics alongside wood particles in a lake environment for 60 days and used amplicon and metagenome sequencing to characterise succession-driven structural and functional shifts in microbial communities colonising the tire-plastisphere.
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.
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.
Toxicity of tire wear particles and the leachates to microorganisms in marine sediments
Researchers investigated the toxicity of tire wear particles and their chemical leachates on bacteria in marine sediments. The study found that aged tire wear particles were more toxic than pristine ones, and that leachates were even more harmful than the particles themselves, with zinc identified as the primary toxicity-causing substance.
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.
Risk assessment of tire wear in the environment – a literature review
This review assesses the environmental risks of tire wear emissions, which release microplastic-like particles containing polymers and potentially toxic chemicals into water and soil. While initial risk estimates suggest low risk from the particulate emissions themselves, the chemicals that leach from tire particles remain poorly characterized. The findings are relevant to human health because tire wear is one of the largest sources of microplastic pollution, and the leached chemicals may enter drinking water.
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.
