Microplastics influence organic carbon depletion in macroaggregates and soil structural stability in the Yanhe catchment
Researchers investigated how microplastics within soil aggregate fractions affect organic carbon retention and structural stability in the Yanhe catchment, finding that microplastics accelerate organic carbon depletion from macroaggregates and reduce soil structural stability. The results suggest that microplastic contamination in agricultural soils may compound land-use-driven degradation of soil quality.
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.
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.
Characteristics and Driving Mechanism of Soil Organic Carbon Content in Farmland of Beijing Plain: Implication for the Fate of Engineered Polymers in Soil

Linking rhizospheric microbiota and metabolite interactions with harvested aboveground carbon and soil carbon of lakeshore reed wetlands in a subtropical region
Researchers studied how soil microorganisms and plant-produced chemicals in wetland reed rhizospheres interact to influence carbon storage in lakeside wetlands. Understanding these relationships helps protect wetlands as important carbon sinks in the face of climate change.
Land Use, Microorganisms, and Soil Organic Carbon: Putting the Pieces Together
Researchers compared soil microbial diversity, organic carbon distribution, and ecosystem function across a gradient of land uses on two contrasting small island systems, one minimally human-influenced and one heavily settled. Human settlement significantly reduced microbial diversity and altered organic carbon cycling, particularly in the uppermost coastal zones.
Structural and Functional Characteristics of Soil Microbial Communities in Forest–Wetland Ecotones: A Case Study of the Lesser Khingan Mountains
Researchers examined soil microbial communities across a forest-to-wetland gradient in China's Lesser Khingan Mountains, comparing mixed forest, conifer forest, wetland edge, and natural wetland. Natural wetland soils harbored the most distinct bacterial communities, driven primarily by high organic matter, nitrogen, and phosphorus content.
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.
The Impact of Litter from Different Belowground Organs of Phragmites australis on Microbial-Mediated Soil Organic Carbon Accumulation in a Lacustrine Wetland
Despite its title referencing wetland litter decomposition and soil carbon, this paper studies how decomposing roots and rhizomes of common reed (Phragmites australis) affect microbial communities and organic carbon accumulation in a Chinese lake wetland — not microplastic pollution. It examines how plant organ type and flooding conditions influence carbon cycling through microbial pathways and is not relevant to microplastics or human health.
