Microplastic Contamination of Sediment and Water Column in the Seine River Estuary
AI summary Read the abstract
Microplastic contamination is documented throughout the Seine River estuary in both water and sediments, with particle concentrations varying by tidal cycle and proximity to urban discharge points. Estuaries act as transitional accumulation zones where riverine microplastics concentrate before entering the marine environment, amplifying exposure for estuary-dwelling species.
Nowadays, microplastic (MPs) pollution is well documented in marine ecosystems since the first publication alarming about marine plastic pollution in 1972 [1]. Similarly, continental contamination is more and more investigated. More recently, interest for estuarine...

Research Progress on Sources and EcologicalEffects of Microplastics in Sediments
AI summary Read the abstract
This review synthesizes research on the sources and ecological effects of microplastics in sediments, tracing transport pathways from terrestrial runoff through freshwater systems to marine sediment sinks and documenting impacts on benthic organisms and ecosystem function. Sediments serve as long-term reservoirs of microplastic pollution, making sediment ecology a critical lens for understanding cumulative environmental burden and food chain exposure risks posed by plastic debris.
Distribution of Microplastics in Semi-urban Estuary Water Along the West Coast of India
AI summary Read the abstract
Researchers investigated microplastic distribution in semi-urban estuary waters along India's west coast, finding that human activities such as port operations, tourism, fishing, and industrial discharges are major contributors to microplastic contamination in these ecologically vital coastal ecosystems.
A Review of Microplastics in Aquatic Sediments: Occurrence, Fate, Transport, and Ecological Impact
AI summary Read the abstract
Researchers reviewed how microplastics accumulate in aquatic sediments — particularly the ocean floor — finding that sediments act as a long-term sink where plastics alter microbial communities and harm bottom-dwelling organisms, meaning the ecological damage of plastic pollution extends far beyond what is visible at the water surface.
Microplastic contamination in the Seine River estuary
AI summary Read the abstract
Researchers investigated microplastic contamination in the Seine River estuary in France, contributing to the growing body of evidence that major European rivers are significant conduits for transporting plastic pollution from inland areas to coastal marine environments.
First assessment of microplastic particles contamination using two complementary analysis methods from the source to the estuary of the Loire River, France
AI summary Read the abstract
Researchers conducted the first comprehensive survey of microplastic contamination along the full length of France's Loire River, sampling water and sediment at 20 stations near major cities and tributaries over three months to map spatial pollution patterns from source to estuary.
