ClearMicroplastic sequestration in saltmarsh sediments from Eastern Brazil
Researchers examined microplastic sequestration in saltmarsh sediments from Todos os Santos Bay in eastern Brazil, a bay subject to substantial industrial and urban inputs. Saltmarsh sediments accumulated high concentrations of microplastics, functioning as long-term sinks for plastic pollution in this coastal ecosystem.
Salt marshes as the final watershed fate for meso- and microplastic contamination: A case study from Southern Brazil
Researchers found that salt marshes act as significant sinks for meso- and microplastics transported through a watershed, with plastic particles accumulating in marsh sediments at densities reflecting upstream land use — highlighting salt marshes as both indicators of catchment-wide plastic pollution and potential long-term reservoirs.
Role of saltmarsh systems in estuarine trapping of microplastics
Researchers found that saltmarsh vegetation significantly enhances the trapping of microplastics in estuarine sediments compared to adjacent bare mudflats, suggesting that these coastal ecosystems act as important sinks for plastic pollution under tidal flow conditions.

Researchers found widespread microplastic pollution in mangrove soils around Todos os Santos Bay in Brazil, detecting contamination at multiple depths and distances from the tidal area, highlighting mangroves as previously overlooked sinks for microplastic accumulation.
The Role of Estuarine Wetlands (Saltmarshes) in Sediment Microplastics Retention
Researchers compared microplastic levels in vegetated saltmarsh sediments versus bare sediments in a Portuguese estuary and found that saltmarsh vegetation traps significantly more plastic particles. Fibers were the most common type of microplastic found, followed by fragments. The study suggests that coastal wetlands act as natural filters for microplastic pollution, which has implications for both conservation and pollution management.
Studying the Presence and Distribution of Microplastics in a Norfolk Salt Marsh
Researchers investigated the presence and distribution of microplastics in a Norfolk salt marsh, examining whether fundamental sedimentation processes and dense vegetation make salt marshes significant long-term sinks for microplastic accumulation in coastal environments.
Revealing microplastic and anthropogenic microparticles contamination in tidal blue carbon ecosystems from eastern Brazil
Researchers compared microplastic accumulation in mangrove and salt marsh sediments in Todos os Santos Bay, Brazil, finding that salt marshes contained at least 38 percent more anthropogenic microparticles than mangroves. Fibers were the dominant particle type across both ecosystems, likely originating from synthetic textiles and fishing activities, highlighting the role of these coastal blue carbon ecosystems as sinks for microplastic pollution.
Species-specific plastic accumulation in the sediment and canopy of coastal vegetated habitats
A multi-habitat study of coastal vegetated areas in Portugal found that saltmarsh vegetation showed the strongest ability to trap macroplastics in sediment, while microplastics were distributed similarly across all habitat types. Subtidal habitats retained more microplastic fibers on their canopy than intertidal habitats, highlighting how plant structure and submersion depth influence plastic accumulation.
Microplastic distribution characteristics and storage in a multi-species saltmarsh
This study examined how microplastics are distributed and stored in a multi-species saltmarsh ecosystem. Saltmarshes trapped significant quantities of plastic particles, acting as long-term sinks that expose the organisms living in these coastal habitats to ongoing plastic contamination.
Spatial distribution of microplastics in the superficial sediment of a mangrove in Southeast Brazil: A comparison between fringe and basin
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.
Microplastic Hotspots on a Tropical Estuarine-Bay System
Researchers mapped microplastic hotspots in the Santos Estuarine System in Brazil — the most populous estuary and largest seaport in the country — characterizing accumulation and export dynamics of microplastics in a high-traffic coastal environment.
Distribution and retention of microplastics in plantation mangrove forest sediments
Researchers investigated the spatial distribution and retention of microplastics in sediments of plantation mangrove forests, finding that mangrove plantations act as effective sinks for microplastics transported by ocean tides, with particle size and shape influencing where plastics accumulate within the forest structure.
Microplastics in saltmarshes: developing extraction methods and examining past accumulation
This thesis developed extraction methods for detecting microplastics in saltmarsh sediments and examined how these particles accumulate over time in coastal habitats. Saltmarshes act as natural filters and carbon stores, making their contamination by microplastics a concern for both ecosystem function and long-term pollution tracking.
