Abstract:
Marine ecosystem contamination by microplastics is extensively documented. However few data is available on the contamination of continental water bodies and associated fauna. The aim of this study was to address the occurrence of microplastics in digestive tract of gudgeons (Gobio gobio) from French rivers. These investigations confirm that continental fish ingested microplastics while 12% of collected fish are contaminated by these small particles. Further works are needed to evaluate the occurence of this contamination.
