Plastic Debris in Urban Water and in Freshwater: Lessons Learned from Research Projects Launched in the Seine Basin Catchment

Abstract

Since 2014, several research projects were launched or in progress on plastic debris issue at the scale of the Seine Bassin catchment, combining a high population density and a strong anthropogenic pressure. These projects, illustrated in Fig. 1, are investigating both macro- and micro-plastics (<5 µm) in urban water and in freshwater upstream and downstream of Paris Megacity (France). The keynote will provide a global overview on the knowledge gained from these projects and draw the major learned lessons.Fig. 1.
