Microplastic concentrations in freshwater during a flood event, a case study of the Seine river catchment
AI summary Read the abstract
Microplastic concentrations in freshwater were measured during a flood event to understand how storm-driven flow affects microplastic transport in rivers. The study found that flooding significantly altered microplastic abundances and distribution, with flood pulses mobilizing plastics stored in riverbed sediments and floodplains.

Microplastics concentrations in freshwater during a flood event, a case study of the Seine river catchment
AI summary Read the abstract
Researchers measured microplastic concentrations in the Seine River catchment during a major flood event in January 2018, finding that flood conditions significantly increased microplastic transport from land to river. The study addresses a critical knowledge gap about how extreme weather events affect microplastic fluxes in densely populated watershed systems.
Microplastics in sediment deposited along the Seine River after a major flood event (February 2021)
AI summary Read the abstract
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.
Microplastic and microfiber fluxes in the Seine River: Flood events versus dry periods
AI summary Read the abstract
A study of the Seine River found that microfiber and microplastic concentrations in the water column spiked dramatically during flood events compared to dry periods, demonstrating that episodic high-flow events are major transport pulses that can overwhelm patterns observed during routine low-flow monitoring.
Storm Response of Fluvial Sedimentary Microplastics
AI summary Read the abstract
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.
Seine Plastic Debris Transport Tenfolded During Increased River Discharge
AI summary Read the abstract
Researchers monitored plastic debris transport in the Seine River in France, finding that plastic flow increased tenfold during high river discharge events compared to low-flow conditions, demonstrating that episodic flood events dominate riverine plastic emissions to the ocean.
