ClearМacrophyte thickets as traps for microplastics: retention rates and mechanisms
Researchers examined the mechanisms and retention rates by which macrophyte thickets trap microplastic particles in freshwater bodies, analyzing how particle properties — including hardness, size, density, and concentration — and plant morphological characteristics influence retention. They found that retention rates ranged from 22 to 100% across macrophyte species for particles of 1-5 mm, with trapping driven by flow resistance, wave energy attenuation, mechanical interception by plant structures, and adhesion enhanced by sticky periphyton biofilms.
Leaf morphology affects microplastic entrapment efficiency in freshwater macrophytes
Researchers found that leaf morphology significantly affects the ability of freshwater macrophytes (aquatic plants) to trap microplastics, with leaf shape and surface texture influencing particle capture efficiency. The findings suggest that aquatic vegetation plays an underappreciated role in microplastic retention and transport in freshwater ecosystems.
A low-impact nature-based solution for reducing aquatic microplastics from freshwater ecosystems
Researchers developed a nature-based solution using the submerged plant Myriophyllum aquaticum to capture and retain microplastics from freshwater ecosystems. Through optimization experiments, they achieved high retention efficiency with minimal environmental disruption. The study demonstrates that aquatic plants can serve as a low-impact, practical tool for reducing microplastic pollution in rivers and lakes.
Transport dynamics of microplastics within aquatic vegetation featuring realistic plant morphology
Researchers investigated how aquatic vegetation with realistic plant structures affects the transport and trapping of microplastics in river environments. They found that floating plant canopies significantly altered water flow and increased microplastic retention, with smaller nanoscale particles being trapped more effectively than larger ones. The study suggests that aquatic vegetation may act as a natural filter, accumulating microplastics and potentially preventing their transport downstream to oceans.
Marine macrophytes retain microplastics
Water sampled within thickets of Baltic Sea macrophytes contained on average 1.7 times more microplastic particles than water sampled outside, with fibers dominating, suggesting that aquatic vegetation physically traps floating microplastics and functions as an important retention zone that concentrates pollution within coastal habitats.
The effects of microplastics size and type on entrapment by freshwater macrophytes under vertical and lateral deposition
Researchers investigated how microplastic particle size and polymer type affect entrapment by freshwater macrophytes, finding that certain aquatic plant species preferentially intercepted specific particle sizes and that plant morphology determined capture efficiency across MPs of varying dimensions.
Macrophytes: A Temporary Sink for Microplastics in Transitional Water Systems
Researchers found microplastics in 94% of macrophyte samples from two northern Adriatic lagoons, with contamination levels ranging from 0.16 to 330 items/g fresh weight showing a site-specific rather than species-specific pattern, and exopolysaccharides on macrophyte surfaces acting as glue to trap plastic particles.
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. Plants with complex leaf structures trapped more microplastics than simpler plants or unvegetated areas. The findings suggest that planted wetlands could serve as a nature-based solution for filtering microplastics from water before they reach rivers and drinking water sources.
Experimental Investigation of the Effects of Vegetation on the Physical Transport and Retention Pattern of Microplastics
Researchers conducted experimental flume studies to investigate how aquatic and riparian vegetation affects the physical transport and retention of microplastics in riverine environments. They found that vegetation significantly increases microplastic retention and alters spatial distribution patterns, suggesting that vegetated riparian zones act as important traps that influence microplastic flux to the ocean.
Effects of macrophytes on micro – And nanoplastic retention and cycling in constructed wetlands
This study tested how the presence of aquatic plants (macrophytes) in constructed wetlands affects the capture and cycling of micro- and nanoplastics. Researchers found that planted wetlands were significantly better at intercepting nanoplastics and also improved nitrogen and phosphorus removal even when exposed to plastic particles. The findings suggest that including macrophytes in constructed wetland designs can enhance their ability to manage plastic pollution in water.
Riparian vegetation as a natural barrier: experimental analysis of plastic particle retention in a vegetated reach
Researchers ran laboratory experiments showing that riverside plants act as natural traps for microplastics, with heavier plastic particles (1.4 g/cm³) being retained at rates up to 93% while lighter, irregularly shaped pieces were captured at twice the rate of disk-shaped ones. Lower water turbulence improved trapping, suggesting that preserving riparian vegetation could help prevent microplastics from reaching the ocean.
Aquatic plants entrap different size of plastics in indoor flume experiments
Researchers found that aquatic plants effectively entrap plastics in riverine environments, with plant species and plastic particle size influencing retention rates, suggesting vegetation plays an important role in limiting downstream plastic transport.
Phytoremediation: A promising approach to remove microplastics from the aquatic environment
This study investigated the interactions between aquatic macrophytes and microplastics as the basis for developing phytoremediation strategies, finding that certain macrophyte species can accumulate MPs from water and sediment and may be candidates for MP removal from contaminated aquatic environments.

Microplastics retention by reeds in freshwater environment
Researchers sampled microplastics in sediment and plant tissue from reed beds in a freshwater environment, finding that reeds retained significantly more microplastics than adjacent open water sediments, suggesting that emergent vegetation may act as a natural microplastic sink.
Aquatic vascular plants – A forgotten piece of nature in microplastic research
Aquatic vascular plants accumulate microplastics on their surfaces through electrostatic attraction, leaf morphology, and periphyton, and these retained particles can be easily ingested by herbivores. The authors argue that plants are an overlooked but important pathway by which microplastics enter freshwater food webs, and deserve more research attention.
Natural filters of marine microplastic pollution: implications for plants and submerged environments
Researchers reviewed how vegetated ecosystems — like wetlands and marshes — act as natural filters that trap microplastics before they flow into waterways, but found that these trapped particles can still harm soil health and plant growth by causing oxidative stress. The review highlights a critical gap: plants help protect aquatic environments from microplastic pollution while simultaneously being harmed by it themselves.
Tracing and trapping micro- and nanoplastics: Untapped mitigation potential of aquatic plants?
Researchers used fluorescently labeled polystyrene particles to trace microplastic and nanoplastic uptake in three aquatic plant species, finding that nanoplastics concentrated primarily in roots via apoplastic transport with bioconcentration factors up to 306, suggesting floating plants like water hyacinth may be useful for removing plastic from contaminated water.

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. Combining vegetated patches with a lagoon achieved microplastic retention rates of up to 99%, suggesting that nature-based wetland designs could be an effective low-cost strategy for filtering microplastics out of wastewater and rivers before they reach the ocean.
