Mangroves as unique but understudied traps for anthropogenic marine debris: A review of present information and the way forward
This review examined mangroves as understudied traps for anthropogenic marine debris, noting that 18 of the top 20 plastic-emitting rivers are associated with mangrove coastlines. Mangroves efficiently accumulate debris through their dense root structures, yet are rarely included in coastal plastic monitoring programs.
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.
Role of mangrove forest in interception of microplastics (MPs): Challenges, progress, and prospects
This review examines how mangrove forests intercept and accumulate microplastics from terrestrial, marine, and atmospheric sources, identifying knowledge gaps in understanding the mechanisms, ecological impacts, and long-term fate of trapped microplastics in mangrove ecosystems.
Distinct microplastics abundance variation in root-associated sediments revealed the underestimation of mangrove microplastics pollution
This study characterized how microplastic abundance varies across root hair, rhizosphere, and non-rhizosphere zones in mangrove sediments, finding that root structures significantly influence microplastic trapping and migration patterns within mangrove ecosystems.
Microplastic Contamination in Water, Sediment, and Biota in Mangrove Forests
This review synthesized research on microplastic contamination in mangrove forest water, sediment, and biota, finding that mangroves act as both sinks and potential sources of microplastics due to their complex hydrodynamics, with ecotoxicological data on mangrove-specific organisms remaining limited.
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.
New insights into sink-source dynamics of mangrove for microplastics: Quantitative evidences from field observation and resuspension simulation
Researchers investigated the sink-source dynamics of mangrove ecosystems for microplastics through field observations and resuspension simulation experiments, finding that sediment microplastic abundance increased substantially from mudflats into mangrove forest. Storm surges were identified as the main driver of vertical microplastic displacement in sediments, while particle shape, color, and size governed resuspension behavior.
Depth Profiles of Microplastic in Sediment Cores in the Mangrove Area of Kuala Gula Mangrove, Malaysia
Researchers profiled microplastic abundance with depth in sediment cores from the Kuala Gula Mangrove in Malaysia, finding 25-130 items per kg dry weight and highest concentrations near rivermouth sites, demonstrating that mangrove sediments are significant microplastic sinks.
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.
Characterization, source, and retention of microplastic in sandy beaches and mangrove wetlands of the Qinzhou Bay, China
Researchers characterized microplastics in sediments from both sandy beaches and mangrove wetlands in Qinzhou Bay, southern China, finding higher abundances in mangrove sediments than beach sediments due to the trapping function of root systems. The study demonstrates that mangroves act as effective sinks for microplastic pollution in coastal zones.
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.
Are mangrove ecosystems plastic accumulation zones?
Researchers monitored macroplastic and microplastic pollution across nine mangrove sites on Cebu Island, Philippines, for over a year using paired removal and reference plots, finding that mangrove ecosystems function as significant plastic accumulation zones with differing dynamics between landward and seaward zones.
Ecological interception effect of mangroves on microplastics
Researchers found that mangroves act as an ecological barrier intercepting microplastics, with MP abundance decreasing from river inputs toward the ocean, demonstrating the role of mangrove ecosystems in filtering plastic pollution before it reaches open waters.

Exponential increase of plastic burial in mangrove sediments as a major plastic sink
This study demonstrated that mangrove sediments are accumulating plastic at an exponential rate, sequestering plastics efficiently due to high sediment accretion rates in these coastal forests.
