Assessment of microplastic contamination in the Loire River (France) throughout analysis of different biotic and abiotic freshwater matrices
International audience The contamination of microplastics (MP) in freshwater environments represent a major way for the MP transport in the environment. The assessment of MP pollution in freshwater compartments is then important to visualize the pressure and the impacts on medium, and to set up nece...

International audience The contamination of microplastics (MP) in freshwater environments represent a major way for the MP transport in the environment.
