ClearRemoval and fate of microplastics in permeable pavements: An experimental layer-by-layer analysis
Researchers tested permeable pavements as a way to capture microplastics from urban stormwater runoff and found they retained 89% to over 99% of microplastic particles. The microplastics accumulated mainly on the pavement surface and in geotextile filter layers, preventing them from reaching natural waterways. This type of sustainable urban drainage could be an effective tool for reducing the amount of microplastics that wash off roads and into the water sources people depend on.

Permeable pavements: A possible sink for tyre wear particles and other microplastics?
Researchers sampled approximately 100 kg of particulate material from seven roads and parking lots to analyze microplastic content including tire wear particles. The study found that tire wear constituted the dominant fraction of microplastics at 0.09% of dry mass, with polypropylene as the most common non-tire plastic type, and that permeable pavements may act as sinks trapping these particles before they reach waterways.
Pavement wear generates microplastics in stormwater runoff
Researchers conducted a two-year field study showing that pavement wear is a distinct and previously underappreciated source of microplastics in urban stormwater, separate from tire wear. They found that asphalt pavement was most susceptible to degradation in the field, while recycled rubber pavers released the most microplastics in lab testing. The study emphasizes the need to consider microplastic generation during pavement material selection and urban infrastructure planning.
Microplastics Characterization in Stormwater: Pavement Source Evaluation and Treatment Efficiency of a Bioretention Cell
Researchers characterised microplastics in stormwater from pavement sources and evaluated the treatment efficiency of a bioretention cell, finding that pavement surfaces contribute substantially to microplastic loading and that bioretention can reduce particle concentrations.
Distribution of microplastics in rainfall and their control by a permeable pavement in low-impact development facility
A low-impact development permeable pavement system in South Korea captured approximately 98% of microplastics present in rainfall runoff, with polyethylene fragments under 100 µm being the most common particle type. The study shows that green infrastructure designed for stormwater management can double as an effective barrier against microplastic entry into freshwater systems, an important finding for urban water quality planning.
Analysis and study of the migration pattern of microplastic particles in saturated porous media pavement
This study modeled how microplastic particles migrate through porous pavement during stormwater runoff, providing insights for designing urban road surfaces that could reduce microplastic transport into groundwater and waterways.
The role of different sustainable urban drainage systems in removing microplastics from urban runoff: A review
Researchers reviewed how nature-based drainage systems like wetlands, bioretention gardens, and permeable pavements can filter microplastics from urban stormwater runoff. These systems capture a significant portion of plastic particles, though smaller fibers remain the hardest to remove, and standardizing detection methods is still needed to compare results globally.
Understanding the dynamics of microplastics transport in urban stormwater runoff: Implications for pollution control and management
Researchers modeled how microplastics travel through urban stormwater runoff into water bodies. They found that a microplastic's shape, size, and density strongly influence whether it settles or floats during transport, and that local factors like street slope and surface friction significantly affect how quickly particles reach storm drains. The findings could help cities design better stormwater management strategies to capture microplastics.
Environmental Performance of the Stormpav Permeable Pavement Using the Stormwater Management Model (SWMM)
This paper is not about microplastics; it models the performance of permeable pavement systems in reducing urban stormwater runoff and associated pollutants such as suspended solids and phosphorus.
Mitigating tire wear particles and tire additive chemicals in stormwater with permeable pavements
Researchers tested whether permeable pavements could filter out tire wear particles and their toxic chemicals, including 6PPD-quinone, which is lethal to salmon. The pavements captured over 96% of tire particles and removed 52-100% of the toxic 6PPD-quinone from stormwater runoff. Since tire wear is a major source of microplastic pollution in urban waterways, permeable pavements could be a practical way to reduce both microplastic contamination and chemical toxicity in streams and rivers.
Long-term environmental performance of precast slabs in permeable pavements: hydraulic functionality and pollutant retention in a real-life installation
Researchers assessed the long-term environmental performance of precast permeable pavement slabs in a real-world installation, finding that accumulated contaminants including microplastics build up within the porous structure over time. The study highlights the dual role of permeable pavements as both stormwater management infrastructure and a potential reservoir for pollutants requiring periodic maintenance.
Permeable Asphalt Pavements (PAP): Benefits, Clogging Factors and Methods for Evaluation and Maintenance—A Review
This review examines permeable asphalt pavements as a stormwater management solution that allows water to infiltrate rather than run off urban surfaces. Researchers found that while these pavements effectively filter pollutants including microplastics from stormwater, their performance degrades over time due to sediment clogging. The study evaluates methods for assessing and maintaining pavement permeability to sustain their environmental benefits.

Is road pavement wear a source of microplastics in stormwater runoff?
This study investigated whether road pavement wear is a measurable source of microplastics in stormwater runoff, distinct from the better-characterized tire wear contribution. Pavement-derived particles were identified in stormwater samples, confirming that road surface material itself contributes to microplastic loading in urban runoff alongside tire wear and other sources.
Nature-Based Urban Drainage Solutions Using Industrial Waste-Incorporated Pervious Concrete Pavements
Scientists tested special concrete made with recycled materials like old concrete and ceramic waste to see if it could clean dirty stormwater runoff from city streets. The recycled concrete worked well at filtering out pollution and dirt from the water while staying strong enough for sidewalks and parking lots. This matters because cleaner stormwater means less pollution flowing into rivers and drinking water sources that affect human health.

Microplastic sampling strategies in urban drainage systems for quantification of urban emissions based on transport pathways
Researchers developed and applied microplastic sampling strategies across an entire urban municipal catchment under both dry and wet weather conditions, finding that wastewater treatment plants remove over 96% of microplastics but still emit 189 kg per year, while wet-weather emissions from high-traffic subcatchments reached 1,952 grams per population equivalent per year, far exceeding dry-weather levels.
Microplastics and Tire Wear Particles in Urban Stormwater: Abundance, Characteristics, and Potential Mitigation Strategies
Researchers measured microplastic concentrations in urban stormwater and found levels ranging from about 4 to 59 particles per liter, with tire wear particles making up roughly 95% of all particles detected. Microlitter capture devices reduced microplastic loads by 35 to 88%, and constructed wetlands provided additional removal. The study suggests that targeted stormwater treatment infrastructure could meaningfully reduce the flow of microplastics into rivers and coastal waters.
