ClearCarbon 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.
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.
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.
Source, fate, toxicity, and remediation of micro-plastic in wetlands: A critical review
Researchers reviewed how microplastics enter, accumulate in, and damage natural wetlands — ecosystems that filter water and support biodiversity — finding that while wetlands may actually trap plastic particles like a sink, the resulting contamination poses serious ecological risks that are still poorly understood.
Abundance of microplastics in a typical urban wetland in China: Association with occurrence and carbon storage
Researchers measured microplastic contamination in a Chinese urban wetland and estimated how much carbon the plastic particles contribute to the ecosystem. While microplastic-carbon currently makes up less than 0.3% of total organic carbon in the wetland, projections suggest this could rise to over 4% by 2100 if plastic production trends continue. The study highlights that microplastics are not just pollutants but are also subtly altering the carbon balance of ecosystems.
Effect of microplastics on CO2 emission from Yellow River Delta wetland
Researchers found that microplastic contamination in Yellow River Delta wetland soils altered CO2 emissions, with different polymer types and concentrations producing varying effects on soil carbon dynamics — raising concern that plastic pollution could undermine the carbon sequestration function of coastal wetlands.
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.
Distinct impacts of microplastics on the carbon sequestration capacity of coastal blue carbon ecosystems: A case of seagrass beds
Researchers examined how microplastic pollution affects the ability of seagrass beds to capture and store carbon, a process important for combating climate change. Evidence indicates that microplastics can alter sediment properties, disrupt microbial communities, and inhibit seagrass growth, all of which reduce carbon storage capacity. The study highlights that microplastic contamination may be undermining one of nature's key tools for removing carbon dioxide from the atmosphere.
Fate and Effects of Macro- and Microplastics in Coastal Wetlands
Researchers compiled data from 112 studies to evaluate how macro- and microplastics accumulate in and affect coastal wetlands including mangroves, salt marshes, and seagrass beds. They found that plastic concentrations in wetland sediments and marine animals were roughly 200 times higher than in the water column, indicating these ecosystems act as major plastic sinks. The study warns that plastic accumulation can alter sediment properties, harm wildlife, and disrupt the carbon storage function of these critical habitats.
Impact of elevated environmental pollutants on carbon storage in mangrove wetlands: A comprehensive review
Researchers synthesized global studies on pollutant impacts in mangrove wetlands — which store about 10% of coastal ocean carbon — finding that microplastics reduce carbon stocks by 1-12% by impairing photosynthesis and destabilizing sediments, while heavy metals and oil spills compound the damage to these critical climate carbon sinks.
Recent advances in the research on effects of micro/nanoplastics on carbon conversion and carbon cycle: A review
This review examines how microplastics and nanoplastics are disrupting the global carbon cycle, the natural process that moves carbon through the environment. Microplastics interfere with the microorganisms that help convert and store carbon, and they reduce the ability of oceans and coastal ecosystems to absorb carbon dioxide. These disruptions could worsen climate change, which in turn affects food production and human well-being.
Microplastic Pollution in Oceans: A Barrier to Achieve Low Carbon Society
Microplastics in the ocean are not just a pollution problem — they may also impair the ocean's ability to absorb carbon dioxide from the atmosphere, undermining one of Earth's most important climate regulators. This review examines how ocean microplastic pollution interferes with carbon sequestration processes and argues that reducing plastic production and improving waste management are essential steps for both climate and environmental health.
Water level regimes can regulate the influences of microplastic pollution on carbon loss in paddy soils: Insights from dissolved organic matter and carbon mineralization
Researchers examined how water level fluctuations in wetlands regulate the influence of microplastic pollution on carbon cycling, finding that alternating wet and dry conditions altered decomposition rates and greenhouse gas emissions in MP-contaminated wetland soils.
The Crucial Nexus of Microplastics on Ecosystem and Climate Change: Types, Source, Impacts, and Transport
This review summarizes the current understanding of microplastic types, sources, environmental impacts, and transport pathways across ecosystems. It highlights that microplastics not only harm organisms through ingestion and physical damage but may also influence climate change by affecting soil carbon storage and ocean processes. The review emphasizes that microplastic pollution is a global challenge requiring coordinated solutions across waste management, policy, and consumer behavior.
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.
Potential synergy of microplastics and nitrogen enrichment on plant holobionts in wetland ecosystems
This review explores how microplastics and excess nitrogen fertilizer may work together to harm wetland plant health by disrupting the beneficial microbes that live on and around plant roots. The combination could accelerate microplastic breakdown while simultaneously weakening plant defenses and nutrient cycling. Since wetlands help filter water that people use, damage to these ecosystems could indirectly affect water quality and human health.
Microplastic residues in wetland ecosystems: Do they truly threaten the plant-microbe-soil system?
Researchers used a controlled pot experiment to assess microplastic effects on wetland plant growth, soil microbial communities, and nutrient cycling, finding that MPs altered soil enzyme activity and shifted bacterial community composition but had variable effects on plant growth depending on plastic type.
Contribution of Microplastics to Carbon Storage in Coastal Wetland Sediments
Microplastic occurrence was measured in coastal sediments across different habitat types in Hong Kong, and the carbon content of the particles was used to estimate that microplastics represent a small but measurable contribution to the organic carbon stock in coastal wetland sediments.
From source to sink: Review and prospects of microplastics in wetland ecosystems
This review synthesizes sources, distribution pathways, migration, and fate of microplastics in wetland ecosystems, which occupy the boundary zone between aquatic and terrestrial environments. It identifies wetlands as both important sinks and potential secondary sources of microplastics and calls for more research on microplastic dynamics in these transitional habitats.
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.
