ClearRevealing 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. Areas near aquaculture operations had the highest contamination levels, and the microplastic surfaces showed signs of environmental degradation that could make them more toxic. Mangrove ecosystems act as natural traps for microplastics, concentrating pollution in habitats that are vital for fisheries and coastal protection.
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.

Study of microplastics pollution in sediments and organisms in mangrove forests: A review
This review examined 53 studies on microplastic pollution in mangrove forests, finding that these coastal ecosystems act as traps that retain microplastics in their sediments and root systems for extended periods. Researchers found that fiber-shaped and brightly colored microplastics were most commonly detected in organisms like mollusks, crustaceans, and fish living in these habitats. The highest concentrations of microplastics in mangrove environments were reported in China.
Contamination of microplastics in mangrove sediment cores from Lach Huyen area, Hai Phong city, Vietnam
Microplastic concentrations in sediment cores from mangrove forests near a major Vietnamese port averaged over 1,300 particles per kilogram — substantially higher than comparable regions globally — with fibres comprising 80% of particles and concentrations decreasing with sediment depth, suggesting recent intensification of pollution. Mangrove sediments act as long-term plastic sinks, and the high fibre burden raises concern for the benthic organisms and communities that depend on these critical coastal ecosystems.
Presence of microplastics in water, sediments and fish species in an urban coastal environment of Fiji, a Pacific small island developing state
Researchers conducted the first assessment of microplastic levels in surface water, sediments, and fish from the urban coastal environment of Suva, Fiji. The study confirmed the presence of microplastics across all three matrices in this Pacific small island developing state, and evaluated contributions from local sources including wastewater, highlighting that microplastic pollution affects even remote island nations.
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.
Distribution of microplastics in the tidal flats of La Parguera, Puerto Rico
Researchers studied the distribution of microplastics in tidal flat sediments behind mangrove forests at four sites in southwest Puerto Rico. They found an average of about 149 microplastic particles per kilogram of sediment, with abundance increasing at greater distances from mangrove trees. The study suggests that mangrove density and local human activity levels influence how microplastics accumulate in these critical coastal ecosystems.
Profil Pencemaran Mikroplastik Pada Sedimen Ekosistem Mangrove di Pulau Serangan, Bali
Indonesian researchers measured microplastic contamination in mangrove sediments at Serangan Island, Bali, sampling across different depths and land-use types to map the distribution of plastic particles in this coastal ecosystem. Mangroves act as natural plastic traps due to their dense root networks, making them important sentinels for monitoring coastal plastic pollution.
Microplastics in mangroves with special reference to Asia: Occurrence, distribution, bioaccumulation and remediation options
This review examines microplastic contamination in Asian mangrove ecosystems, finding higher pollution levels near fishing, tourism, and industrial areas. Organisms throughout the mangrove food web, from shellfish to fish, accumulate microplastics based on their feeding habits and habitat. While mangrove plants can trap some microplastics in their roots, the widespread contamination of these coastal ecosystems raises concerns about the safety of seafood harvested from mangrove areas for human consumption.

Researchers investigated microplastic and trace element pollution in mangrove soils and plant tissues across areas with varying levels of human activity in Bima Bay, Indonesia. They found that microplastic levels were highest near hotels and lowest in rural areas, with plant tissues selectively accumulating certain polymer types like polyamides. The results highlight that mangrove forests act as sinks for plastic pollution, with contamination levels closely tied to local human activity.
Spatial and vertical distribution of microplastics in mangrove sediment in the southern Philippines
This study mapped microplastic contamination in the sediments of three mangrove forests in Mindanao, Philippines, finding particles at all sites with counts ranging from 83 to 2,250 items per kilogram depending on location.
