Summary

Researchers collected tire wear particles from roadside drains and natural environments near a major UK road, finding that these particles are abundant and widespread yet frequently undetected in environmental monitoring, suggesting tyre wear is a major but under-reported microplastic source.

Owing to their physical and chemical properties, particles generated by the abrasion of tyre tread against road surfaces, or tyre wear particles, are recognised as microplastics. Recent desk-based studies suggest tyre wear to be a major contributor of microplastic emissions to the environment. This study aimed to quantify tyre wear in roadside drains and the natural environment near to a major road intersection. Tyre particles were identified by visual identification and a subsample confirmed as tyre wear by GC-MS using N-cyclohexyl-2-benzothiazolamine (NCBA) as a marker. The abundance of tyre wear within roadside drains was greater in areas associated with increased braking and accelerating than that with high traffic densities (p = < 0.05). Tyre particle abundance in the natural environment ranged from 0.6 ± 0.33 to 65 ± 7.36 in 5 mL of material, with some evidence of decline with distance from the road. This study offers preliminary data regarding the generation and abundance of this under-researched microplastic.
