Wheels of Contamination: Car tire microplastics from source to sea
AI summary Read the abstract
Researchers traced car tyre microplastics from their generation through environmental transport pathways to eventual deposition in the sea, estimating that more than 55% of tyre-wear particles enter aquatic environments via runoff and atmospheric transport. The study synthesised existing data on tyre microplastic sources, emission rates, and fate to map the full contamination pathway from road surfaces to ocean ecosystems.
It is estimated that more than 55 Also see: https://micro2024.sciencesconf.org/559635/document

Wheels of Contamination: Car tire microplastics from source to sea
AI summary Read the abstract
Researchers traced the pathway of car tire microplastics from their origin on road surfaces through environmental transport routes to marine deposition, estimating that over 55 million kilograms of tire wear particles enter aquatic environments annually. The study synthesized evidence on emission rates, transport mechanisms, and ecological risks associated with tire-derived microplastics reaching the sea.
Tire Abrasion as a Major Source of Microplastics in the Environment
AI summary Read the abstract
This study analyzed tire wear particles as a major source of microplastics in the environment, estimating that tire abrasion contributes a substantial fraction of total microplastic emissions globally and highlighting road runoff as a key delivery pathway to waterways.
Environmental risks of car tire microplastic particles and other road runoff pollutants
AI summary Read the abstract
Researchers conducted the first comprehensive environmental risk assessment of tire wear microplastic particles and their associated chemical pollutants in European road runoff. They found that tire wear particles and several related chemicals pose measurable risks to organisms in surface water and sediment. The study suggests that tire wear is a significant but often overlooked source of microplastic pollution with real consequences for aquatic ecosystems.
Swedish sources and pathways for microplastics to the marine environment
AI summary Read the abstract
Researchers reviewed Swedish sources and transport pathways of microplastics to the marine environment, identifying road tire wear and abrasion as the dominant emission source at approximately 13,000 tonnes per year, with stormwater, wastewater, and atmospheric deposition as primary pathways to aquatic systems.
Microplastics from tyre and road wear A literature review
AI summary Read the abstract
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.
