Bornemann, J.; Nitzsche, K.N.; Bigalke, M. & Weber, C.J. (2026): Dataset of From Road to Field: Accumulation of Tire and Road Wear Particles in Road-Adjacent Cropland Soils.
AI summary Read the abstract
Researchers measured tiny particles worn off tires and roads that build up in farm soil near roadways, these particles are a common but overlooked source of microplastics. Since this cropland is used to grow food, the findings raise questions about whether these particles could work their way into our food supply, though this study focuses on measuring the particles in soil rather than testing health effects directly.

AI summary Read the abstract
Researchers measured tiny bits of tire and road wear (basically microplastic and rubber particles that flake off tires as you drive) in farmland soil near busy roads, finding that this debris builds up in the fields where our food is grown. This matters because it suggests road traffic pollution isn't staying on the road, it's making its way into agricultural soil, raising questions about whether these particles could eventually end up in crops or affect soil health. This dataset provides the raw measurements needed for future studies to figure out how big a concern this actually is for food safety.
Detection of microplastics in soil samples from the area of traffic route
AI summary Read the abstract
Researchers detected microplastics in soil samples collected from roadside areas, finding plastic particles at multiple locations and noting that road traffic generates microplastics through tire wear and pavement abrasion. Roads and their immediate surroundings are significant terrestrial sources and repositories of microplastics that can be transported by wind and runoff.
Tyre and road wear particles - A calculation of generation, transport and release to water and soil with special regard to German roads
AI summary Read the abstract
This study calculated that German roads generate 75,000 to 98,000 tons of tire and road wear particles annually, with a significant portion reaching surface waters and roadside soils. The findings highlight tire wear as a major but often overlooked source of microplastic pollution requiring better data and management strategies.
Impregnation levels and gradient of tire wear particle content of surface soils adjacent to a major road
AI summary Read the abstract
Researchers assessed the impregnation levels and spatial gradient of tire and road wear particle (TRWP) contamination in surface soils adjacent to a major road, investigating how proximity to the road surface affects the degree of microplastic loading in roadside soil profiles. The results showed significant TRWP concentrations in soils closest to the road, with contamination gradients extending laterally into adjacent land, confirming roadside soils as durable repositories of tyre-derived microplastics.
Concentrations of tire wear microplastics and other traffic-derived non-exhaust particles in the road environment
AI summary Read the abstract
Researchers measured actual environmental concentrations of tire wear microplastics and other traffic-derived non-exhaust particles in a rural highway setting, providing field-based data to complement the theoretical estimates that dominate current literature.
