ClearThe 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.
Nature-Based Solutions for Removal of Microplastics from Wastewater: Technologies, Challenges, and Prospects
This review evaluates nature-based solutions for removing microplastics from wastewater, including constructed wetlands, green infrastructure, and aquatic plants. The study found that these approaches can achieve removal efficiencies up to 99-100%, offering ecologically friendly alternatives to conventional treatment methods, though challenges remain with long-term efficiency and removal of other contaminants.
Nature-based Solutions to Wastewater Treatment of Microplastics: Technologies, Challenges, and Prospects
This review examined nature-based solutions (NbS) for microplastic removal from wastewater, including constructed wetlands, algal bioreactors, and mangrove systems. NbS approaches show promise as cost-effective, ecologically integrated complements to conventional treatment, though removal efficiencies vary widely and long-term fate of trapped microplastics remains understudied.
Retention of microplastics by interspersed lagoons in both natural and constructed wetlands
Researchers used laboratory wetland models to test how well constructed wetlands with interspersed lagoons and aquatic vegetation can capture microplastic particles from water.

Role of Constructed Wetlands in Wastewater Treatment and Mitigation of Emerging Contaminants
This review examines how constructed wetlands can serve as sustainable, cost-effective systems for treating wastewater and removing emerging contaminants including nanoplastics, pharmaceuticals, and endocrine-disrupting chemicals. The authors describe how physical, chemical, and biological mechanisms work together in these engineered ecosystems to break down persistent pollutants. The study suggests that constructed wetlands offer a promising nature-based solution for addressing contaminants that conventional treatment methods struggle to remove.
Microplastics occurrence and fate in full-scale treatment wetlands
Researchers assessed microplastic occurrence and fate across full-scale treatment wetlands, finding that constructed wetlands effectively remove a significant proportion of MPs from wastewater but that removal efficiency varies with wetland design and MP characteristics.
Constructed wetlands for emerging pollutants removal: A decade of advances and future directions (2014–2024)
This review evaluates a decade of research on constructed wetlands, an eco-friendly water treatment approach, for removing emerging pollutants including antibiotics and microplastics. The evidence shows that constructed wetlands can effectively remove many types of pharmaceuticals and microplastics from water through a combination of physical filtration, microbial breakdown, and plant uptake. These low-cost, nature-based systems could help reduce human exposure to microplastics in treated water, though optimizing their design for different pollutant types remains a challenge.

Researchers identified and characterized microplastics in constructed wetlands used for treating domestic wastewater, finding MP accumulation in the substrate and plants and assessing how well these nature-based treatment systems retain plastic particles before effluent is discharged.
Microplastics profile in constructed wetlands: Distribution, retention and implications
This study assessed microplastic distribution, retention, and implications within constructed wetlands used for wastewater treatment, finding that wetlands trap substantial quantities of MPs but that retention efficiency varies by plant species and wetland design. The results suggest constructed wetlands both remove and potentially accumulate MPs as a secondary pollution source.
A review on the remediation of microplastics using constructed wetlands: Bibliometric, co-occurrence, current trends, and future directions
This review examined the use of constructed wetlands as a nature-based solution for removing microplastics from water, analyzing research trends and knowledge gaps through bibliometric analysis. Researchers found that constructed wetlands show promise for microplastic remediation, but significant barriers remain in understanding the removal mechanisms involved. The study identifies key research directions needed to optimize wetland design for effective microplastic pollution control.
The fate of microplastics from municipal wastewater in a surface flow treatment wetland
Researchers investigated microplastic retention in a full-scale surface flow treatment wetland receiving municipal wastewater, measuring microplastic concentrations in inflow, outflow, and atmospheric deposition, and finding significant retention within the wetland. Treatment wetlands represent a potential nature-based solution for reducing microplastic discharge to receiving water bodies.
Retention of microplastics and tyre wear particles in stormwater ponds
Researchers analyzed stormwater retention ponds to assess their effectiveness at capturing microplastics and tire wear particles from urban runoff. They found microplastics in all water samples and significantly higher concentrations in pond sediments, suggesting that the ponds do retain a portion of these pollutants. The study indicates that while stormwater ponds offer some mitigation, their long-term performance for trapping emerging contaminants like microplastics needs further evaluation.

This review examines the effectiveness of constructed wetlands for removing micro- and nanoplastics from water, comparing laboratory and full-scale results. Researchers found that while constructed wetlands show promising removal capabilities, the unique physical and chemical properties of plastic particles mean that lab-scale efficiencies may differ significantly from real-world performance, highlighting the need for more field-scale studies.

The study provides evidence that constructed wetlands can serve as a practical nature-based solution for mitigating microplastic pollution from urban sewer systems.
Understanding microplastic retention in surface flow constructed wetlands: The impact of aquatic macrophytes
This study tested how well constructed wetlands with different aquatic plants retain three common types of microplastics: polyethylene beads, tire wear particles, and synthetic fibers.
