Les rivières sont censées être les principales voies de transfert des plastiques des terres vers l'océan (Lebreton et al., 2017 ; Schmidt et al., 2017). Cependant, il existe encore un manque important de connaissances sur la façon dont les déchets fluviaux, y compris les macroplastiques, sont transférés vers l'Océan.

Methods to quantify plastic transport in rivers have greatly improved during the past few years. As a first approach, visual counting is currently the simplest way to assess plastic transport with minimal effort and cost. It usually results in underestimations of plastic input into the sea of about one to two order of magnitude when compared to mod...

Rivers are supposed to be the main pathways of plastics from lands into the Ocean (Lebreton et al., 2017; Schmidt et al., 2017). However, there is still a huge lack of knowledge on how riverine litter, including macroplastics, is transferred into the Ocean. Quantitative measurements of macroplastic emissions in rivers even suggest that a small frac...
Rivers are a major pathway for plastics between lands and the ocean. At the land-ocean interface, estuaries make the transfer dynamic of plastics complex and nonlinear. That is why very little is known about this dynamic. In this respect, a specific marker (i.e. Microlax packaging) showing date-prints was systematically investigated in different ri...
The dynamics of plastic debris were assessedin the Seine River, especially in the estuary, using plastic bottles equipped with GPS-trackers. In oneyear, 50 trajectories were recorded, covering a wide range of hydrometeorologicalconditions. Results show a succession of stranding/remobilization episodes in combination withalternating upstream and dow...
Plastic pollution, especially microplastics (MP) pollution, is a hot topic in both mainstream media and scientific literature. Although rivers are potentially the major transport pathway of this pollution to the sea, plastic contamination in freshwater bodies is comparatively understudied. Microplastic pollution in freshwater fish is of growing int...
