ClearTracks of travel: unveiling tire particle concentrations in Swiss cantonal road soils
Researchers quantified tire wear particle concentrations in roadside soils along fifteen Swiss cantonal roads with relatively low traffic volumes. They found average concentrations of 111,000 particles per kilogram of dry soil, with particle counts and sizes decreasing with increasing distance from the road. The study also found positive relationships between tire wear particle numbers and associated pollutants like polycyclic aromatic hydrocarbons and trace metals.
