Micro-plastics, plastic debris smaller than 5 millimeters, arouse growing concern among researchers and the general public.
The presence of microplastics in the oceans is a proven phenomenon and is the subject of numerous investigations.
There are few data on continental ecosystems near or far from the supposed sources of emission. Freshwater microplastics research, more particularly in the mountains and isolated sites, is indeed very little documented.
The PLASTILAC project aims to determine the concentration of microplastics in alpine altitude lakes.
