Microplastics were found in all three sample types, indicating that plastic contamination has penetrated the seagrass ecosystem and is being ingested by organisms within it.
Studies on microplastic contamination in seagrass beds at Spermonde Archipelago of Makassar Strait, Indonesia
Microplastics were detected in seagrass beds of the Spermonde Archipelago in Indonesia's Makassar Strait, with concentrations influenced by proximity to populated islands and fishing activity. The study documents plastic contamination in an important tropical seagrass ecosystem that supports fisheries and coastal livelihoods.
Microplastic abundance and its relationship with sediment grain size in seagrass and bare flats of Panjang Island, Banten Bay, Indonesia
Researchers surveying Panjang Island in Indonesia's Banten Bay found microplastics throughout both seagrass and bare sediment areas, with finer-grained sediments accumulating more particles. Seagrass beds appeared to trap more microplastics than bare areas, meaning these critical coastal habitats — already under stress — may concentrate plastic pollution and expose the organisms sheltering in them to higher doses.
Microplastic in Cymodocea rotundata Seagrass Blades
Microplastics were found adhering to the surfaces of seagrass blades in Indonesian coastal waters, trapped by the rough texture of organisms growing on the leaves. Seagrass beds, which are important marine habitats, may act as a sink that accumulates microplastics from the surrounding water.
Microplastics in the seagrass ecosystems: A critical review
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.
Abundance and distribution of microplastics in seawater, sediment, and macroalgae sea grapes Caulerpa racemosa from Semak Daun Island, Jakarta Bay, Indonesia
Researchers found microplastic contamination in sea grapes, seawater, and sediment from Jakarta Bay's Semak Daun Island, with fragments dominating in macroalgae and fibers in water and sediment, and washing treatments reducing but not eliminating contamination.
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.
A review of microplastic impacts on seagrasses, epiphytes, and associated sediment communities
This review synthesizes research on microplastic accumulation in seagrass ecosystems, examining effects on seagrass plants, epiphytic communities, and associated sediment biota. The authors identify seagrass meadows as both sinks for microplastics and potentially sensitive ecosystems where plastic contamination may disrupt complex ecological relationships.
Microplastic abundance in sea cucumber at seagrass ecosystem of Bintan Island and surrounding area, Indonesia
Researchers found microplastic contamination in sea cucumbers across seagrass ecosystems of Bintan Island, Indonesia, with the highest abundance of 52 particles/individual recorded in Pengudang waters, and fiber-type microplastics dominating at 84 particles/individual across all three harvested species.
Early evidence of microplastics on seagrass and macroalgae
Researchers quantified microplastic densities on the surfaces of three marine macrophyte species (two macroalgae and one seagrass) collected in situ, finding measurable contamination on all species. The results suggest that macrophytes may serve as an important but underappreciated pathway for microplastics to enter marine food webs.
Microplastics Content of Seaweeds in the Mariculture Potential Zone at The Southwest of Coastal Bawean Island
Researchers investigated microplastic contamination in seaweeds from Bawean Island, Indonesia, finding that even sheltered coastal waters contained microplastics in red, green, and brown seaweed species collected from mariculture potential zones.
Microplastic, an Emerging Threat to the Global Seagrass Ecosystems: A Review
This review examined microplastic pollution as an emerging threat to global seagrass ecosystems, summarizing contamination levels in seagrass meadows worldwide and effects on seagrass physiology, associated fauna, and carbon sequestration capacity. Microplastic ingestion and physical smothering were identified as the most significant direct impacts on seagrass organisms.
