Microplastic burial potential and ecological risks in mangrove forests of the Amazon River delta
Researchers studied how mangrove forests in the Amazon River delta trap and bury microplastics in their soil, analyzing sediment cores going back over a century. Microplastics were found in nearly all samples, including some deposited before the modern plastic era, suggesting redistribution through sediment movement. The study is the first to quantify the microplastic burial capacity of mangroves, showing these ecosystems act as long-term sinks for plastic pollution.

Current status and trends of research on microplastic fugacity characteristics and pollution levels in mangrove wetlands
This systematic literature review analyzed the distribution, characteristics, and pollution levels of microplastics in mangrove wetlands globally, finding that mangroves act as significant traps for land-based plastics before they reach the open ocean. Fiber morphologies and polymer types reflected terrestrial sources, and microplastic density was highest near urban river inputs.
Assessment of Soil Microplastics and Their Relation to Soil and Terrain Attributes Under Different Land Uses
Researchers assessed microplastic contamination in tropical soils under different land uses including forest, grassland, and agricultural areas. They found that agricultural soils had the highest microplastic concentrations, likely due to the use of plastic-based materials in farming. The study reveals how land use practices and soil characteristics influence the distribution and accumulation of microplastics in tropical environments.
A review on microplastic pollution in the mangrove wetlands and microbial strategies for its remediation
Researchers reviewed the growing problem of microplastic pollution in mangrove wetland ecosystems and its effects on the biological communities that depend on these habitats. They found that microplastic exposure can substantially alter the microbial communities critical to nutrient cycling in mangrove environments. The review also explores microbial bioremediation strategies as a sustainable approach to addressing plastic pollution in these threatened coastal ecosystems.
Characteristics and distribution of microplastics in the coastal mangrove sediments of China
A survey of mangrove sediments along China's coast found microplastics were ubiquitous, with concentrations and polymer types varying by proximity to human activity and hydrological conditions. The study shows that mangrove forests, which provide critical coastal ecosystem services, are accumulating significant quantities of plastic pollution.
Risk Assessment and Influence of Microplastics on mangrove forest soil: Sandwip Island, Chittagong, Bangladesh
This study assessed microplastic contamination and associated ecological risk in mangrove forest soils on Sandwip Island in Bangladesh, a region with limited prior MP research. The authors found widespread MP presence and elevated risk indices, linking contamination to nearby plastic waste sources and tidal transport.
Impact of mangrove forest structure and landscape on macroplastics capture
Researchers surveyed macroplastic accumulation across seven mangrove forests in the Philippines, finding 1.1 items per square meter on average with the highest abundance at landward zones and near river mouths. Mangrove biomass and root structure were positively correlated with plastic capture, confirming that mangrove structural complexity enhances their ability to trap land-derived plastic litter.
How mangrove plants affect microplastic distribution in sediments of coastal wetlands: Case study in Shenzhen Bay, South China
The effect of different mangrove plant species on microplastic distribution in coastal wetland sediments was investigated, finding that plant species significantly influenced where microplastics accumulated. The study suggests that mangrove root and canopy structures create preferential zones for microplastic retention in coastal sediments.
Abundance and characteristics of microplastics in the mangrove sediment of the semi-enclosed Maowei Sea of the south China sea: New implications for location, rhizosphere, and sediment compositions
Microplastics were widespread in mangrove sediments of the semi-enclosed Maowei Sea in southern China, with concentrations influenced by location within the mangrove, proximity to roots, and sediment composition. The study provides new insight into how mangrove ecosystems trap and accumulate microplastics, raising concerns for the health of these ecologically important coastal habitats.
Wetland soil microplastics are negatively related to vegetation cover and stem density
A field study in wetland ecosystems found that microplastic concentrations in soil were negatively correlated with vegetation cover and plant stem density, suggesting that dense vegetation may reduce microplastic deposition or enhance burial. The relationship implies that healthy wetland plant communities may provide some protection against microplastic accumulation.
Assessing microplastic contamination levels in ghana's mangrove wetlands
Researchers assessed microplastic contamination levels in mangrove wetlands in Ghana, examining how mangrove tree morphology facilitates plastic accumulation and what concentrations and polymer types are present in these coastal ecosystems.

Effects of microplastics on carbon release and microbial community in mangrove soil systems
Researchers tested how microplastics affect carbon release and microbial life in mangrove soils at different depths. They found that while topsoil was largely unaffected, deeper soil layers released significantly more carbon dioxide when microplastics were present, particularly biodegradable types like polylactic acid. The study suggests that microplastic contamination in mangrove ecosystems could accelerate carbon loss from deeper soils by disrupting microbial communities and worsening nitrogen limitations.

Revealing Microplastic Contamination in Mangrove Sediments from Setiu Wetlands, Malaysia
Researchers found 2,292 microplastic particles per kilogram of sediment in the mangrove wetlands of Setiu, Malaysia, with over 80% being tiny fibers likely from fishing gear and packaging.
