The Seine River and its basin (70 000 km2, 500 m3/s mean annual discharge) are studied since 1989 by an interdisciplinary research programme (https://www.piren-seine.fr/). The river receives the effluents of about 17 M inhab (70% from Paris conurbation) and from industries. Intensive agriculture using agrochemicals is another cause of water quality...

Rivers are major pathways of plastics from lands into the Ocean. 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 fraction (0.001 to 3%) of the Mismanaged Plastic Waste (MPW) generat...
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...
For over 30 years, the sources and the transfer dynamics of micropollutants have been investigated in the PIREN-Seine programme. Recent works included a wide range of chemicals and biological contaminants of emerging concern (i.e. contaminants whose occurrence, fate and impact are scarcely documented). This chapter presents a brief overview of rese...
International audience
Dans le cadre du projet pluridisciplinaire et international, Val-Uses, des sédiments du fleuve Usumacinta du Mexique ont été prélevés et transportés en France. Leur caractérisation approfondie du point de vue minéralogique, physique, chimique, rhéologique et hydromécanique est présentée en associant des mesures microstructurales et macroscopiques. ...
