Concentrations and Retention Efficiency of Tire Wear Particles from Road Runoff in Bioretention Cells

Bioretention cells are popular stormwater management systems for controlling peak runoff and improving water quality. A case study on a functional large-scale bioretention cell laboratory column experiment was conducted to evaluate the concentrations retention efficiency of towards tire wear particles (TWP). The presence TWP observed in all soil fractions (<50 µm, 50–100 100–500 >500 µm) cell. were higher (30.9 ± 4.1 mg/g) close inlet than 5 m away (19.8 2.4 mg/g), demonstrating influence design. showed high (99.6 0.5%) engineered consisting sand, silty-sand, garden waste compost. This confirmed that built with effectively retained > 25 µm size, their potential as control measures along roads.
