ClearFlooding frequency and floodplain topography determine abundance of microplastics in an alluvial Rhine soil
Researchers found that flooding frequency and local floodplain topography are key determinants of microplastic abundance in alluvial Rhine soils, with frequently flooded low-lying areas accumulating significantly more microplastics than elevated sites.
The fate of microplastics in Rhine floodplains: process and patterns of deposition, distribution and vertical migration in the soil
Researchers analyzed microplastic distribution and vertical migration in three Rhine floodplains near Cologne, Germany, examining lateral distribution patterns, whether meadow vegetation filters microplastics during flooding, and vertical depth profiles in floodplain soils. The study found that microplastics deposit during flood events, with both lateral distance from the river and vegetation cover influencing spatial distribution and vertical penetration in floodplain soils.
Why analysing microplastics in floodplains matters: application in a sedimentary context
This study examined microplastic distribution and accumulation in floodplain areas of Germany, finding that floodplains trap and concentrate microplastics during flood events and serve as long-term storage sites. Floodplains are an important but underappreciated environmental compartment for microplastic accumulation that can release particles back into rivers during future floods.
Spatial analysis of riverine microplastic in a Rhine floodplain soil in Germany
Researchers mapped microplastic distribution in floodplain soils along Germany's Rhine River, finding that flood events spread microplastics far from the riverbank into surrounding land. This shows flooding can contaminate agricultural soils with microplastics, potentially entering food crops.
Microplastics in floodplain soils along the rhine river in germany
Researchers characterized microplastic pollution in floodplain soils along the Rhine River in Germany, focusing on this understudied habitat at the interface of terrestrial and freshwater systems to understand how rivers act as vectors for microplastic transport and deposition.
Microplastics in floodplain soils along the rhine river in germany
Researchers quantified microplastic pollution in floodplain soils along the Rhine River in Germany, examining how this transitional environment between terrestrial and freshwater systems accumulates plastics transported during flood events. The study addressed a gap in knowledge about floodplain soils compared to more commonly studied agricultural soils.
Filter effect of Rhine floodplain vegetation on microplastic deposition during a single flood event in Germany
Researchers examined the role of floodplain vegetation in controlling microplastic deposition during a single Rhine River flood event in Germany, finding that vegetation cover acts as a physical filter affecting spatial distribution of deposited microplastics beyond the topographic and flood-frequency controls identified in previous studies.
Macroplastic retention on river floodplains following flood events
Researchers examined macroplastic retention on river floodplains following flood events, quantifying how much plastic debris is deposited beyond river channels during high-flow conditions and assessing remobilization potential. The study provided data supporting the role of floodplains as significant sinks and secondary sources of macroplastics in riverine transport to the sea.
Deposition and in-situ translocation of microplastics in floodplain soils
This study examined how microplastics deposit and move through floodplain soils during flooding events, finding that floods both deposit and redistribute microplastics in agricultural and riparian soils. The findings help explain how microplastic pollution spreads from rivers into surrounding terrestrial environments.
Data and code for the publication "Flooding frequency and floodplain topography determine abundance of microplastics in an alluvial Rhine soil"
This is a data and code repository for a published study on how flooding frequency and floodplain topography determine microplastic abundance in Rhine River floodplain soils. Floodplains act as microplastic sinks and sources, with regular flooding events redistributing plastic particles across agricultural and natural landscapes.
Filter effect of Rhine floodplain vegetation on microplastic deposition during a single flood event in Germany
Researchers studied how Rhine floodplain vegetation filtered microplastic deposition during a single flood event in Germany, documenting that plant cover created distinct spatial deposition patterns and acted as a significant physical barrier concentrating particles compared to unvegetated floodplain surfaces.
Macroplastic retention on river floodplains following flood events
Researchers investigated macroplastic retention dynamics on river floodplains following flood events, examining how elevated flows transport and deposit plastic debris beyond the main channel. The study quantified floodplain retention relative to channel retention and assessed how flood magnitude influences remobilization and downstream delivery of plastics toward the sea.
Microplastics in Swiss Floodplain Soils
Researchers surveyed Swiss floodplain soils and found microplastics present across multiple sites, suggesting that floodplain dynamics — periodic inundation and sediment deposition — contribute to microplastic accumulation in terrestrial environments.
Storm Response of Fluvial Sedimentary Microplastics
Researchers investigated how storm events affect microplastic concentrations in river sediments, finding that flood conditions remobilize stored particles and significantly increase microplastic loads in fluvial systems. The study identified key physical controls on microplastic storage and transport in river channels.
The role of floodplain vegetation in filtering microplastics during a major Rhine flood event
Researchers investigated microplastic deposition on Rhine floodplain vegetation during a major flood event, finding that floodplain vegetation significantly increases hydraulic roughness and reduces flow velocities, enhancing MP capture and acting as an important filter for microplastics remobilized from the riverbed during high-discharge events.
Microplastics in sediment deposited along the Seine River after a major flood event (February 2021)
Researchers measured microplastics in sediments deposited along the Seine River during and after a major flood event in February 2021. Flood conditions resuspended sediment and transported microplastics from contaminated riverbanks downstream, redistributing them to new locations. The findings confirm that flood events are significant drivers of microplastic transport and can complicate pollution management efforts.
Spatial Connections between Microplastics and Heavy Metal Pollution within Floodplain Soils
Researchers investigated the spatial relationship between microplastic contamination and heavy metal pollution in floodplain soils. They found that microplastics and heavy metals co-occur in these environments and that their distribution patterns are linked to flooding events and sediment deposition. The study suggests that floodplains act as temporary sinks where these pollutants accumulate together, potentially compounding their environmental impact.
Occurrence and Spatial Distribution of Microplastics in River Shore Sediments of the Rhine-Main Area in Germany
Researchers surveyed river shore sediments and documented the occurrence and spatial distribution of microplastics, finding that sediment accumulation zones along riverbanks are hotspots for microplastic deposition.
Macroplastic concentrations in the water column of the river Rhine increase with higher discharge
Researchers used trawl nets at multiple depths in the Rhine River to track macroplastic pollution in the water column, finding that plastic concentrations rise sharply during high river discharge (flooding). During low-flow conditions, plastics accumulated near the riverbed, revealing that hydrology plays a key role in where and how much plastic moves through river systems.
Deposition and in-situ translocation of microplastics in floodplain soils
A study of microplastic deposition and in-situ vertical translocation in floodplain soils found that flooding events deposit microplastics from river water onto floodplain surfaces, and that subsequent rainfall and bioturbation can move particles downward through the soil profile.
Flood Characteristics Drive River-Scale Macroplastic Deposition
Researchers analyzed macroplastic deposition along river floodplains during 14 events across two Dutch rivers, comparing flood and non-flood conditions. They found that larger floods deposited two to three times more plastic than non-flood conditions, with deposition patterns varying by flood type: summer floods trapped plastics in inundated vegetation while winter floods deposited plastics in wide, slow-flowing floodplain sections. The study suggests that as flood severity and plastic pollution both increase, floods will play an even more prominent role in distributing plastic pollution.
Spatial patterns of mesoplastics and coarse microplastics in floodplain soils as resulting from land use and fluvial processes
Plastic particles were found throughout floodplain soils along the Lahn River in Germany down to 2 meters depth, with higher concentrations near river channels and on riparian grassland than on farmland. The study provides early evidence that river flooding distributes plastics vertically into soil profiles over time.
