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.
Determination of aerobic and anaerobic biological degradability of waste tyres
Researchers examined the aerobic and anaerobic biodegradability of waste tire rubber in aquatic environments, finding very limited biological degradation under both conditions, confirming that tire-derived particles persist as long-term environmental contaminants.
Assessing the Biodegradability of Tire Tread Particles and Influencing Factors
Researchers tested the biodegradability of tire tread particles under natural and UV-weathered conditions, finding that biodegradation was limited and that UV weathering affected the process. Tire wear particles persist in the environment and contribute to microplastic, chemical, and particulate matter pollution.
[Aging and Small-sized Particles Release Characteristics of Tire Microplastics in Various Environmental Media].
Researchers simulated the aging of tire microplastics from cars and electric bicycles under UV illumination in both dry and aquatic environments, finding that 30 days of UV exposure caused surface roughening, cracking, and flaking while increasing the carbonyl index and releasing smaller particles, revealing distinct aging and fragmentation behaviors across environmental media.
Weathering of a micro and nanosized tire particle mixture increases ingestion and growth inhibition in larval fish and juvenile mysid shrimp
Researchers investigated how environmental weathering changes the toxicity of tire particle mixtures to larval fish and juvenile mysid shrimp. The study found that weathered tire particles were more readily ingested and caused greater growth inhibition compared to pristine particles, suggesting that aging in the environment makes tire-derived microplastics more harmful to marine organisms.
Aging of Tire Particles in Deep-Sea Conditions: Interactions between Hydrostatic Pressure, Prokaryotic Growth and Chemical Leaching.
This laboratory study simulated deep-sea conditions to investigate how high hydrostatic pressure and prokaryotic biofilms affect tire particle aging. Deep-sea pressure and microbial colonization altered the physical and chemical properties of tire particles, with implications for their long-term fate as a microplastic sink.
A 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.
Toxic effects of environmentally persistent free radicals (EPFRs) on the surface of tire wear particles on freshwater biofilms: The alleviating role after sewage-incubation-aging
Researchers investigated how tire wear particles affect freshwater biofilms, which are communities of microorganisms that play important roles in aquatic ecosystems. They found that reactive chemical compounds on the surface of fresh tire particles caused significant toxicity, reducing photosynthesis and biological activity in the biofilms. The study suggests that aging in sewage environments reduces the toxicity of tire wear particles by breaking down these harmful surface chemicals.
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.
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.
