The Plastic-Seine research program: integrated approach of microplastic fate and effects in the Seine estuary

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.

PLASTIC-Seine research project: Microplastic Flux and Impact on biota in the Seine estuary.

AI summary · Read the abstract

This international conference presentation reported on the PLASTIC-Seine project studying microplastic fluxes and biological impacts in the Seine River estuary, a major European river system that transports plastic pollution from Paris to the English Channel.

Holistic Approach to the Marine Microplastics: Sampling, Characterization, Consequences

AI summary · Read the abstract

A standardized universal sampling protocol for pelagic microplastics is proposed to generate qualitative and quantitative data that can be meaningfully compared across ocean regions. Harmonizing collection and characterization methods is a prerequisite for building the global dataset needed to track microplastic pollution trends over time.

Microplastics in the Marine Environment: Sources, Distribution, Biological Effects and Socio-Economic Impacts

AI summary · Read the abstract

Researchers reviewed the sources, distribution, biological effects, and socioeconomic impacts of microplastic pollution in marine environments, finding that rivers and estuaries are the primary land-to-ocean transport pathways. The review emphasizes that microplastics transfer adsorbed pollutants and additives through food webs to top predators, and that reducing plastic production and improving waste management are essential long-term solutions.
