ClearEvaluating the Effectiveness of Bioretention Cells for Urban Stormwater Management: A Systematic Review
This systematic review found that bioretention cells effectively reduce stormwater runoff volume and peak flow rates while removing pollutants including heavy metals, nutrients, and suspended solids. Performance varies significantly by region and design parameters, with soil media composition and vegetation type being the most influential factors.
The impact of treated wastewater and biosolids from the municipal wastewater treatment plant on water and carbon dioxide effluxes from soils
Researchers measured water and CO2 effluxes from Cambisol and Arenosol soils amended with stabilized or composted sewage sludge or irrigated with treated wastewater over a growing season, finding that sewage sludge amendments significantly increased CO2 emissions while treated wastewater irrigation had negligible effect on either CO2 or water efflux, which was primarily governed by plant canopy cover.
A Re-evaluation of Wetland Carbon Sink Mitigation Concepts and Measurements: A Diagenetic Solution
This review re-evaluates wetland carbon sequestration measurement concepts, arguing that organic carbon accumulation (CA) in sediments is not equivalent to net sequestration because it requires subtraction of labile allochthonous carbon inputs and intrinsic recalcitrant deposits. The authors propose a diagenetic framework to improve the accuracy of greenhouse gas mitigation assessments for wetland ecosystems.
Greenhouse gas emissions and control measures for constructed wetland: A systematic review
This systematic review examines greenhouse gas emissions from constructed wetlands used for wastewater treatment, finding that CH4, CO2, and N2O fluxes vary widely by region and wetland configuration, and that emerging contaminants including microplastics influence emissions. The review proposes design and operational strategies to reduce the climate footprint of constructed wetlands while preserving their water treatment benefits.
A Methodology for Industrial Water Footprint Assessment Using Energy-Water-Carbon Nexus

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.
Field assessment of engineered bioretention as microplastics sink through site characterization and hydrologic modeling
A field study of bioretention cells — garden-like stormwater filters used in green infrastructure — found that their soils contained 7 to 10 times more microplastics than background soils, with polypropylene and polyethylene dominating. This confirms that bioretention systems are effective at capturing microplastics from urban runoff, but it also raises questions about what happens to the accumulated plastic over time and whether it eventually leaches back into groundwater.
Multiyear Water Quality Performance and Mass Accumulation of PCBs, Mercury, Methylmercury, Copper, and Microplastics in a Bioretention Rain Garden
Researchers conducted a multiyear study of a bioretention rain garden near San Francisco Bay and found it effectively reduced concentrations of PCBs, mercury, methylmercury, copper, and microplastics in stormwater runoff, though mass accumulation of contaminants in the rain garden substrate increased over time.
New Bioretention Drainage Channel as One of the Low-Impact Development Solutions: A Case Study from Poland

A closer look at Toronto's water quality control design criteria for bioretention cells
This engineering study evaluated water quality performance and cost-effectiveness of bioretention cells at different design sizes in Toronto, finding that the current design standard of capturing the 90th percentile storm (25 mm) is likely too conservative and not cost-efficient. A lower design threshold could maintain similar pollutant removal while significantly reducing construction costs.
Bioretention cells remove microplastics from urban stormwater
A 2-year field study characterized microplastics in urban stormwater runoff and measured how effectively a bioretention cell (a low-impact development infrastructure) removed them. The bioretention cell significantly reduced microplastic concentrations in stormwater, demonstrating its potential as a mitigation strategy for urban runoff-driven microplastic pollution.

[Removal Mechanism of Microplastics in Bioretention Systems and the Influence of Their Enrichment on the Treatment of Pollutants in the System].
Researchers reviewed how bioretention systems, a low-impact stormwater management strategy, can remove microplastics from urban runoff through adsorption, filtration, and biodegradation. However, because microplastics resist degradation and have large surface areas, they tend to accumulate in these systems over time, forming composite pollution with other contaminants. The study found that microplastic accumulation altered soil properties, impeded plant growth, and reduced the system's ability to remove nutrients, particularly dissolved nitrogen.
