ClearHeightened threat of aged microplastics in constructed wetlands: impacts on nitrogen cycles and greenhouse gas emissions
Researchers studied the effects of aged fibrous microplastics on nitrogen cycling and greenhouse gas emissions in constructed wetlands and found that high concentrations of aged MPs reduced nitrogen removal efficiency and increased N₂O emissions compared to pristine MPs. The results suggest aging intensifies the environmental disruption caused by microplastics in treatment wetlands.
Exploring the potential impacts of microplastics on greenhouse gas emissions in wastewater treatment
This review analyzed how microplastics in wastewater treatment plants affect greenhouse gas (GHG) emissions, focusing on mechanisms by which microplastics alter microbial communities and their metabolic processes. The plastisphere was identified as a key site for altered methane and nitrous oxide production, with implications for climate reporting from the water sector.
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.
Recent advances towards micro(nano)plastics research in wetland ecosystems: A systematic review on sources, removal, and ecological impacts
Wetland ecosystems act as important sinks for micro- and nanoplastics, which were found to cause ecotoxicological effects on wetland plants, animals, and microbial communities, including shifts in microbial composition relevant to pollutant removal. Micro/nanoplastics exposure also affected conventional pollutant removal efficiency and greenhouse gas emissions from wetland systems.

This paper is not directly about microplastics — it reviews greenhouse gas emissions from wastewater collection systems and estimates China's annual emissions, without a focus on plastic pollution.
Non-negligible impact of microplastics on wetland ecosystems
This review examines microplastic pollution in wetland ecosystems, which sit between land and water and act as natural filters. Microplastics in wetlands come from sewage, agricultural runoff, and atmospheric deposition, with polyethylene and polypropylene fibers and fragments being the most common types found. The paper highlights that microplastics can harm wetland plants, animals, and microbes, and may even increase greenhouse gas emissions by serving as an unusual carbon source for soil microorganisms.
Impact of Anthropogenic Activities on Microbially Mediated Carbon Dioxide and Methane Emissions in Wetlands: A Review and Prospects
This review examines how human activities such as salinization, over-fertilization, heavy metal input, and microplastic pollution affect microbial carbon cycling processes in wetland ecosystems. The study highlights how these environmental challenges alter the microbial interactions that mediate carbon dioxide and methane emissions, providing a foundation for understanding greenhouse gas dynamics in disturbed wetlands.
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.
Carbon Cycling in Wetlands Under the Shadow of Microplastics: Challenges and Prospects
This review examines how microplastics disrupt carbon cycling in wetlands, which are critical ecosystems for capturing and storing carbon that would otherwise contribute to climate change. Microplastics can damage plant roots, alter soil microbial communities, and accelerate the breakdown of stored organic carbon, leading to increased greenhouse gas emissions. The findings highlight that microplastic pollution may undermine wetlands' ability to help regulate the climate.
Ecological Functions of Microbes in Constructed Wetlands for Natural Water Purification
This review examines the ecological functions of microbial communities in constructed wetlands for wastewater treatment, highlighting how dominant phyla including Proteobacteria, Bacteroidetes, Actinobacteria, and Firmicutes drive nitrogen transformations, phosphorus cycling, and organic matter degradation. The authors identify microplastic accumulation, antibiotic resistance gene spread, and greenhouse gas emissions as key challenges, and recommend engineered substrates, biochar amendments, and hybrid designs to improve future treatment performance.

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.
A review on the fate of micro and nano plastics (MNPs) and their implication in regulating nutrient cycling in constructed wetland systems
This review examines how micro- and nanoplastics interact with the biological, chemical, and physical processes in constructed wetlands, which are nature-based systems used to treat wastewater. Researchers found that these tiny plastics can interfere with nitrogen and phosphorus removal by affecting the microbial communities, plant health, and substrate chemistry within the wetlands. The study highlights that as microplastic levels increase in wastewater, their presence could reduce the overall treatment effectiveness of these green infrastructure systems.
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.
Microplastics and Climate Change: Unveiling Ecological Impacts and Addressing Research Gaps
This review synthesizes research from 2019 to 2024 on the mechanisms by which microplastics influence greenhouse gas emissions — including CO2, methane, and nitrous oxide — in terrestrial and aquatic environments, examining roles such as nutrient adsorption and microbial substrate provision. The authors highlight the particularly underexplored contribution of nitrous oxide, which has a global warming potential approximately 300 times that of CO2, and call for standardized methodologies and long-term field studies to assess cumulative climate impacts.

Microplastics promote methane emission in estuarine and coastal wetlands
This study found that microplastics in coastal and estuarine wetlands increase methane emissions by boosting the activity of methane-producing microorganisms while reducing methane-consuming ones. Both conventional and biodegradable plastics had this effect, meaning microplastic pollution is not just a direct health concern but also contributes to climate change by amplifying greenhouse gas release from natural ecosystems.
Mechanisms underpinning microplastic effects on the natural climate solutions of wetland ecosystems
Microplastics are entering wetlands worldwide and disrupting the plants and microbes that make wetlands powerful carbon sinks, potentially turning these ecosystems from carbon absorbers into greenhouse gas emitters. This review maps the mechanisms by which microplastics interfere with wetland carbon storage and calls for this threat to be factored into global climate commitments like the Paris Agreement's net-zero targets. The findings are a warning that plastic pollution could quietly undermine one of nature's most important tools for fighting climate change.
