ClearEficiencia de los pavimentos permeables para la retención de microplásticos de la escorrentía urbana
Researchers evaluated the effectiveness of permeable pavements as sustainable urban drainage systems for retaining microplastics from urban stormwater runoff, testing their performance under controlled laboratory conditions calibrated to average rainfall patterns in Valencia, Spain. Results showed a significant reduction in microplastic particle counts in water passing through the permeable pavement layers.
Permeable pavement blocks as a sustainable solution for managing microplastic pollution in urban stormwater
Researchers tested whether permeable pavement, the kind of pavement that lets water drain through it, can filter out microplastics from urban stormwater runoff. They found it can trap microplastic particles effectively, suggesting permeable pavement could be a practical tool for reducing the amount of microplastics that wash into rivers and oceans from city streets.
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.
Removal 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.
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.
Plastic pollution risks in bioretention systems: a case study
Researchers investigated plastic pollution in urban stormwater bioretention systems and found these green infrastructure features both accumulate microplastics from road runoff and risk leaching plastic particles into groundwater, raising concerns about their role as pollution pathways.
Application of Porous Concrete Infiltration Techniques to Street Stormwater Inlets That Simultaneously Mitigate against Non-Point Heavy Metal Pollution and Stormwater Runoff Reduction in Urban Areas: Catchment-Scale Evaluation of the Potential of Discrete and Small-Scale Techniques
This is a civil engineering review on using porous concrete in stormwater inlets to reduce runoff and filter heavy metals in urban areas; it is not a microplastics research paper.
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.
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.
Caractérisation des microplastiques présents dans les sédiments des bassins de retenue des eaux pluviales.
This French-language study characterizes microplastics found in the sediments of stormwater retention basins, which collect runoff from urban and agricultural areas. The findings show that these basins accumulate significant microplastic loads, making them potential hotspots of concentrated plastic pollution.
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.
Design of model microplastics to study their transport in urban waters
Researchers designed model microplastic particles with controlled physical properties to systematically study their transport behavior in urban water systems.

Microplastic pollution in sediments of urban rainwater drainage system
Researchers found microplastics in all sediment samples from a university campus rainwater drainage system, with abundances ranging from 80 to 2,610 particles/kg and the highest concentrations in student living areas, suggesting that land use patterns and management practices influence microplastic accumulation in urban stormwater infrastructure.
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.
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.
