ClearThe fate of microplastics/nanoplastics (MPs/NPs) in constructed wetlands: Addressing methodological gaps and experimental challenges from lab-scale to full-scale
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.

Critical role of benthic fauna in enhancing nanoplastics removal in constructed wetland: Performance, fate and mechanism
Researchers found that adding benthic fauna such as clams and worms to constructed wetlands significantly improved the removal of nanoplastics from wastewater.
