Distribution characteristics of microplastics in the soil of mangrove restoration wetland and the effects of microplastics on soil characteristics
Researchers measured microplastic distribution in soils of a mangrove restoration wetland with different planting densities, finding an average abundance of 217 MPs per kilogram of dry soil with higher concentrations in denser planting zones. MPs in the soil also altered wetland soil physicochemical properties including bulk density and organic matter content.
Comprehensive risk assessment of microplastics in tidal channel sediments in amazonian mangroves (northern Brazil)
Researchers assessed microplastic pollution in mangrove sediments along an estuary in the Brazilian Amazon, finding contamination at all nine sampling sites with an average of 433 particles per kilogram. While the contamination was classified as low-level, the presence of microplastics in this remote Amazonian ecosystem shows the global reach of plastic pollution. Mangroves are critical nursery habitats for fish and shellfish, so contamination here could affect seafood safety for local communities.
Microplastic sequestration in saltmarsh sediments from Eastern Brazil
Researchers characterized microplastic accumulation in saltmarsh sediments from Todos os Santos Bay, Brazil, finding high sequestration rates in vegetated coastal zones. The results highlight saltmarshes as important hotspots for microplastic deposition in tropical coastal environments.
Microplastic 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.
Microplastics in Singapore’s coastal mangrove ecosystems
Researchers sampled coastal mangrove ecosystems in Singapore and found microplastics throughout, demonstrating that mangrove habitats accumulate plastic pollution and raising concerns for the organisms that depend on these ecologically important coastal forests.
Microplastic burial potential and ecological risks in mangrove forests of the Amazon River delta
Researchers studied how mangrove forests in the Amazon River delta trap and bury microplastics in their soil, analyzing sediment cores going back over a century. Microplastics were found in nearly all samples, including some deposited before the modern plastic era, suggesting redistribution through sediment movement. The study is the first to quantify the microplastic burial capacity of mangroves, showing these ecosystems act as long-term sinks for plastic pollution.
Risk assessment and influence of microplastics on mangrove forest soil: Sandwip Island, Chittagong, Bangladesh
Researchers assessed microplastic contamination in mangrove forest soils on Sandwip Island, Bangladesh, characterizing the abundance, types, and potential ecological risks of the particles. They found notable levels of microplastic pollution in the mangrove sediments, with fibers and fragments being the most common forms. The study highlights an understudied threat to mangrove ecosystems and calls for greater attention to microplastic impacts on these critical coastal habitats.
Assessment of Soil Microplastics and Their Relation to Soil and Terrain Attributes Under Different Land Uses
Researchers assessed microplastic contamination in tropical soils under different land uses including forest, grassland, and agricultural areas. They found that agricultural soils had the highest microplastic concentrations, likely due to the use of plastic-based materials in farming. The study reveals how land use practices and soil characteristics influence the distribution and accumulation of microplastics in tropical environments.
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.

Researchers monitored macroplastic and microplastic pollution across nine mangrove sites on Cebu Island, Philippines, for over a year using paired removal and reference plots, finding that mangrove ecosystems function as significant plastic accumulation zones with differing dynamics between landward and seaward zones.
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.

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.
