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.
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.
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.
The Main Drivers of Biodiversity Loss: A Brief Overview
This review provided a comprehensive overview of the main drivers of global biodiversity loss, including agricultural expansion, climate change, marine exploitation, urbanization, and invasive species, with land use change threatening 85% of at-risk species.

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.
The web of life: Role of pollution in biodiversity decline
This review examines the role of various forms of pollution in driving biodiversity decline globally. The study highlights how human activities have reshaped natural habitats, and evidence indicates that biodiversity loss can affect ecosystems as significantly as climate change and other major environmental stresses.
Unveiling the Marvels of Indian Wetlands: Distribution, Ecological Importance, Challenges, and Conservation
This review examines the distribution, ecological importance, biodiversity, and conservation challenges of Indian wetlands, comparing them in productivity to tropical evergreen forests and coral reefs. The authors discuss the essential ecological services wetlands provide — including water supply, flood control, carbon sequestration, and nutrient cycling — and the pressures from growing anthropogenic activity.
The Changes in Dominant Driving Factors in the Evolution Process of Wetland in the Yellow River Delta during 2015–2022
This paper is not about microplastics; it uses satellite time-series imagery to analyze changes in wetland area and type in the Yellow River Delta between 2015 and 2022.
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.
The Impact of Pollution on Biodiversity Loss: A Review
This review synthesized global literature on how air, water, soil, and chemical pollutants — including microplastics — contribute to biodiversity loss. The authors conclude that pollution acts through multiple pathways to reduce species diversity and ecosystem health, often in combination with other stressors.
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.
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.
Impacts of Wetland Degradation on Soil Organic Carbon and Carbon Sequestration Function: A Case Study of the Huixian Wetland in the Li River Basin
Researchers examined how degradation gradients from non-degraded to heavily degraded conditions affect soil organic carbon fractions and carbon fluxes in the Huixian Wetland, China, finding that increasing degradation progressively depleted labile carbon pools — particularly microbial biomass carbon and light fraction organic carbon — and reduced carbon sequestration capacity while increasing CO2 emissions.
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.
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.
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.
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.
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.
Plastic Pollution as a Driver of Seagrass Ecosystem Degradation: a Systematic Review of Impacts and Mitigation Approaches
This systematic review examines how plastic pollution threatens seagrass ecosystems, which are vital for carbon storage, coastal protection, and marine biodiversity. Microplastics and larger debris smother seagrass beds, block light, and introduce harmful chemicals into sediments. Losing these habitats has cascading effects on fish populations and the communities that depend on healthy coastal waters.
A review on microplastics pollution in coastal wetlands
Researchers reviewed existing studies on microplastic pollution in coastal wetlands — ecosystems like mangroves, salt marshes, and tidal flats — summarizing where microplastics accumulate, how they get there, and how they affect wildlife and ecosystem function. These habitats are especially vulnerable because they sit at the boundary between land and sea, trapping plastics carried by both rivers and ocean tides.
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.

Implications of plastic pollution on global carbon cycle
This review examines how plastic pollution disrupts the global carbon cycle through the production of fossil-fuel-based plastics, the release of carbon during plastic degradation, and the leaching of chemical additives into the environment. Microplastics and nanoplastics from degrading plastic waste affect carbon cycling in both soil and water ecosystems. The findings highlight that plastic pollution is not just a waste problem but also contributes to climate-related disruptions that ultimately affect human well-being.
