This study investigates the microplastic contamination of both urban compartments (wastewater and total atmospheric fallout) and surface water in a continental environment. These first investigations on an urban environment confirm the presence of microplastics in sewage, fresh water and total atmospheric fallout and provide knowledge on the type and size distribution of microplastics in the 100-5000-mu m range. For the first time, the presence of microplastics, mostly fibres, is highlighted in total atmospheric fallout (29-280 particles m(-2) day(-1)). High levels of fibres were found in wastewater (260-320 x 10(3) particles m(-3)). In treated effluent, the contamination significantly decreased to 14-50 x 10(3) particles m(-3). In the River Seine, two sampling devices were used to collect both large and small microplastic particles: (i) a plankton net (80-mu m mesh), and (ii) a manta trawl (330-mm mesh). Sampling with the plankton net showed a predominance of fibres, with concentrations ranging from 3 to 108 particles m(-3). A greater diversity of both microplastic shapes and types was found during manta trawl sampling but at much lower concentrations (0.28-0.47 particles m(-3)). This combined approach could be relevant and implemented in future studies to provide an accurate overview of microplastic distribution in freshwater.
