Abstract
1.Introduction
2.Material and methods
– Study site
– Sediment sample collection
– Sediment characterisation
-Microplastic analyses: analytical procedure
– Precautions about microplastic cross-contamination
3.Résults
– Sediment characterisation
– Variability of MP distribution in a sample
– Variability of MP concentrations in samples at the river segment scale
4.Discussion
– Influence of hydrosedimentary processes and geomorphologicallyinduced depositional conditions on MP concentrations
– Influence of hydrosedimentary processes and geomorphologically- induced depositional conditions on MP sizes and polymer types
– Comparison with MP concentrations in other river sediment samples
– Importance of a systemic approach to understand MP distribution in rivers
5.Conclusion and perspectives
