Constructed wetlands as neglected fixed source of microplastics and antibiotic resistance genes in natural water bodies?

This review examines constructed wetlands as potential sources of microplastics and antibiotic resistance genes (ARGs) released into natural water bodies, assessing their effectiveness at removing both types of pollutants. While constructed wetlands can reduce microplastics and ARGs through adsorption, filtration, and biodegradation, they may also act as reservoirs that release these contaminants under certain conditions.

The 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.

An examination of Nature-Based Solutions’ ability to retain New and Emerging Pollutants – Preliminary results from a UK field test

Researchers conducted a UK field test of nature-based solutions to evaluate their ability to retain new and emerging pollutants, including microplastics, from stormwater in informal settlements lacking formal drainage infrastructure. Preliminary results indicate that constructed wetland-type systems can intercept a range of contaminants that persist through conventional treatment, though performance varied across pollutant classes.
