ClearMicroplastic abundance and its relationship with sediment grain size in seagrass and bare flats of Panjang Island, Banten Bay, Indonesia
Seagrass beds are thought to trap microplastics more efficiently than bare seafloor, but a study in Indonesia's Banten Bay found no statistically significant difference in microplastic abundance between seagrass and unvegetated sediments, with counts ranging from 240 to 1,880 particles per kilogram of dry sediment. Sediment grain size did influence microplastic accumulation, with finer sediments retaining more particles. These findings suggest that local hydrodynamic conditions and sediment texture may matter more than vegetation type when predicting where microplastics concentrate in coastal ecosystems.
Trapping of microplastics and other anthropogenic particles in seagrass beds: Ubiquity across a vertical and horizontal sampling gradient
Researchers examined how seagrass beds trap microplastics and other anthropogenic particles by sampling along a vegetation cover gradient from dense beds to less vegetated patches. The study found that seagrass vegetation enhances the accumulation of plastic debris in both sediment and among plant structures. Evidence indicates that seagrass ecosystems act as significant sinks for microplastic pollution, with implications for the organisms that depend on these habitats.

Researchers investigated the relationship between microplastic accumulation and sediment texture in seagrass meadows along the southeast coast of India. They found that seagrass sediments contained significantly higher microplastic concentrations than unvegetated areas, with polyethylene being the most common polymer detected. The findings suggest that seagrass meadows act as traps for microplastic pollutants, with sediment grain size influencing accumulation patterns.
Factors influencing microplastic abundances in the sediments of a seagrass-dominated tropical atoll
Researchers investigated factors controlling microplastic abundance in sediments of a seagrass-dominated tropical atoll. They found that seagrass density, water flow patterns, and proximity to human settlements all influenced microplastic accumulation, with denser seagrass meadows trapping more particles in their sediments. The study raises concerns that microplastic buildup in seagrass ecosystems could threaten the ecological services these habitats provide, including carbon storage and biodiversity support.
Seagrass beds reveal high abundance of microplastic in sediments: A case study in the Baltic Sea
Seagrass bed sediments in the Baltic Sea were found to harbor significantly higher microplastic concentrations than surrounding bare sediments, indicating that seagrass canopies trap and accumulate microplastics and may be underappreciated hotspots of contamination.
Seagrass beds acting as a trap of microplastics - Emerging hotspot in the coastal region?
Seagrass beds in coastal waters were found to trap and accumulate microplastics at higher concentrations than surrounding unvegetated sediments, acting as effective sinks for plastic particles due to their dense canopy structure. This positions seagrass meadows as emerging hotspots of microplastic contamination in coastal ecosystems.

This review critically assessed microplastic contamination in seagrass ecosystems worldwide, finding that these nearshore habitats accumulate significant plastic pollution due to their proximity to human activities and the trapping effect of submerged vegetation.
Microplastics Characteristics in Water and Sediment From Three Ecosystems on Sari Ringgung Beach, Pesawaran Regency, Lampung Province
Researchers sampled water and sediment across mangrove, seagrass, and coral reef ecosystems at an Indonesian beach, finding microplastic contamination in all three habitats with the mangrove ecosystem showing the highest concentrations — up to 467 particles per kilogram of sediment. Fibers, films, and fragments smaller than 1 mm were the most common forms found, highlighting widespread microplastic pollution across multiple coastal ecosystem types.
ACCUMULATION OF MICROPLASTICS (<300 µM) IN MANGROVE SEDIMENTS OF BANDA ACEH CITY, INDONESIA
Researchers measured microplastic accumulation in mangrove sediments in Banda Aceh, Indonesia, finding up to 3,840 particles per kilogram of sediment — with plastic pellets and fibers smaller than 300 micrometers being the most common types — suggesting these coastal ecosystems are acting as significant traps for plastic pollution from nearby land and waterways.
Microplastic assessment in Seagrass ecosystem at Kodingareng Lompo Island of Makassar City
Researchers assessed microplastic contamination across multiple components of the seagrass ecosystem at Kodingareng Lompo Island in Indonesia, finding microplastics in sediments, surface water, fish, and benthic organisms. The study establishes baseline pollution data for a biodiverse coastal habitat and underscores the widespread reach of microplastic contamination.
The power of Posidonia oceanica meadows to retain microplastics and the consequences on associated macrofaunal benthic communities
Researchers investigated how Posidonia oceanica seagrass meadows accumulate microplastics in coastal sediments and the consequences for associated marine communities. The study found differences in microplastic abundance and composition at various depths and between vegetated and unvegetated sites, suggesting that seagrass beds may act as sinks for microplastic pollution with potential impacts on benthic organisms.

Researchers measured microplastic abundance in sediments at multiple stations in Pangandaran waters, West Java, Indonesia, finding the highest counts at station 2 (12,622 particles, mostly fibers and fragments) and the lowest at station 4 (1,809 particles). The study identifies oceanographic factors — currents, waves, and tides — as key drivers of microplastic movement and accumulation patterns in coastal Indonesian waters.

The first occurrence, spatial distribution and characteristics of microplastic particles in sediments from Banten Bay, Indonesia
Researchers reported the first characterisation of microplastic pollution in sediments from Banten Bay, Indonesia, finding an average concentration of 267 particles/kg dry weight across 25 stations, with expanded polystyrene foam (38%) and particles sized 500-1000 micrometres as the most common form. Higher concentrations near river mouths and fine sediment areas suggest riverine inputs as the primary pathway for plastic pollution into this rapidly developing coastal bay.
