Since 2014, Johnny Gasperi and Bruno Tassin launched different research projects on the plastic litter issue, i.e. Plastic-Seine, Plastic-Air, Micro-Plast, etc.
The researches carried out aimed at investigating the sources, fluxes, and fate of plastic debris – from macroplastics to microplastics – in urban area and hydrosystems, including the receiving anthropized water. The final objective is i) to provide knowledge on the abundance and characterization of plastic debris in urban sources (wastewater, runoff, atmospheric deposition, etc.), ii) to assess plastic debris fluxes, and iii) to evaluate the contribution of the greater Paris area compared to the Seine river catchment.
