ClearTire 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.
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.
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.
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.
The Influence of Microplastics from Ground Tyres on the Acute, Subchronical Toxicity and Microbial Respiration of Soil
Researchers assessed the toxicity of ground tire microplastics on soil organisms and microbial respiration, finding subchronic phytotoxicity effects that highlight the environmental risks posed by tire wear particles accumulating in soils.
Behind conventional (micro)plastics: An ecotoxicological characterization of aqueous suspensions from End-of-Life Tire particles
Researchers studied the toxic effects of ground-up end-of-life tire particles on zebrafish larvae and found that finer tire powder was more harmful than coarser granules. The smaller particles released chemicals into the water that altered over 100 proteins involved in metabolic processes. The study suggests that recycled tire materials leach toxic substances that could pose risks to aquatic organisms.
Environmentally relevant concentrations of tyre particles cause toxicity in estuarine invertebrates
Researchers tested the toxicity of tire particles at environmentally relevant concentrations on estuarine species, finding that current environmental levels are sufficient to cause harm. The study identified the most sensitive species and life stages and highlighted tire particles as a priority microplastic source for regulatory attention.
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.
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.
Comparative Toxicity of Micro, Nano, and Leachate Fractions of Three Rubber Materials to Freshwater Species: Zebrafish and .
Researchers compared the toxicity of micro, nano, and leachate fractions of three rubber materials—including tire rubber—to freshwater organisms. Nano-fractions and leachates generally showed higher toxicity than larger rubber particles, with leached chemicals driving much of the observed biological harm.
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.
Time-dependent toxicity of tire particles on soil nematodes
Tire wear particles—a major source of microplastics—were found to become increasingly toxic to soil nematodes over time as chemical additives leach out. The time-dependent toxicity means that older, weathered tire particles in soil may pose greater ecological risks than freshly deposited ones.
Environmentally relevant concentrations of tyre particles cause toxicity in estuarine invertebrates
Researchers exposed estuarine organisms to environmentally relevant concentrations of tire particles and measured toxicity endpoints including survival, reproduction, and behavior. Tire particles caused significant adverse effects at concentrations already found in some urban estuaries, suggesting current environmental levels pose ecological risks.
