ClearAbundance 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.
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.

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.

Microplastic distribution was compared between fringe and basin mangrove zones in southeastern Brazil, finding that basin forests trapped significantly more microplastics than fringe areas due to lower hydrodynamic energy and greater sediment retention.
Preliminary assessment of microplastic in rhizosphere and non-rhizosphere region of mangrove at four locations along Karachi coast, Pakistan
Researchers assessed microplastic distribution in rhizosphere and non-rhizosphere mangrove sediments at four sites along the Karachi coast, finding 14,960 particles with slightly higher counts in non-rhizosphere zones. Beads were the most common particle type, and FTIR confirmed polyethylene and polypropylene as dominant polymers.
Anthropogenic marine debris and its dynamics across peri-urban and urban mangroves on Penang Island, Malaysia
Researchers tracked the accumulation of marine debris in urban and semi-urban mangroves on Penang Island, Malaysia, finding that debris abundance varied with season, tidal patterns, and proximity to urban areas. Mangroves act as debris traps, concentrating plastic waste including microplastics that filter through their root systems.
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.
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.
Preliminary Study on the Role of Mangroves in Entrapping Microplastics in Tuticorin Coast of Gulf of Mannar, Southeast Coast of India
Researchers compared microplastic concentrations in mangrove sediments versus open-beach control sites along the coast of southern India and found consistently higher levels within mangrove areas. Polyethylene and polypropylene fibers in the 1–3 mm range were most common, and weathering analysis confirmed significant environmental degradation of the particles. The findings suggest that mangrove root systems act as natural traps for microplastics, which has implications for both ecosystem health and the many coastal communities that rely on mangroves for fisheries and shore protection.

Researchers investigated microplastic contamination levels in Ghana's mangrove wetlands, examining how the morphology of mangrove root systems traps and accumulates plastic particles of all sizes and assessing the threat posed to these ecologically critical 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.
Responses of mangrove (Kandelia obovata) growth, photosynthesis, and rhizosphere soil properties to microplastic pollution
Researchers found that polyethylene, polypropylene, and PVC microplastics significantly impaired mangrove (Kandelia obovata) root growth, photosynthesis, and soil microbial properties after 12 months of exposure, threatening mangrove ecosystem health.
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.
Microplastics Presence in Rhizophora mangle Roots throughout Fishponds and Open Coasts in Moloka'i, Hawaii
This study found microplastics in the roots of red mangrove trees at both fishpond and open coast sites in Hawaii, documenting plastic contamination in a critical coastal habitat. Mangrove ecosystems are important nursery habitats for fish and shellfish, so microplastic contamination there has broader food chain implications.
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.

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.
Abundance and distribution of microplastics in tropical estuarine mangrove areas around Penang, Malaysia
This study documented microplastic pollution in tropical mangrove estuaries around Penang, Malaysia, finding thousands of plastic particles in both water and sediment samples. Concentrations were particularly high near the more urbanized Seberang Perai area, where sediment contained up to 4,000 particles per kilogram. The research highlights that tropical mangroves, which serve as important nursery habitats for marine life, are accumulating significant amounts of microplastic pollution.

Plastic pollution in mangrove ecosystems: A global meta-analysis
This meta-analysis pooled global data on plastic pollution in mangrove ecosystems and found that these critical coastal habitats act as natural plastic traps.

Impacts of Microplastics on Mangroves - A Review
Mangrove forests act as natural traps for microplastics due to their dense root systems that slow water flow, leading to higher microplastic accumulation in mangroves than other coastal zones. This matters because the build-up harms mangrove plants at the cellular and physiological level, threatening these ecologically critical habitats that protect coastlines and support fisheries.
