CLEAN MONT BLANC
Search for microplastics in the Mont-Blanc massif
Study the quality of water emanating from glaciers by mapping the concentration levels of microplastics carried by the atmosphere:
- Spot samples using a filtration device on the outlets of 18 glaciers representative of the massif
- Chemical analyzes in the laboratory : quantification of the particles collected and determination of the type of polymer
- Carrying out a mapping of the concentrations of microplastics carried by the atmosphere (spatial distribution of particles from several study sites)
Sampling around Mont-Blanc
Symbol of the Alps, the Mont-Blanc massif extends over France, Switzerland and Italy.
Composed of multiple glaciers exposed to atmospheric deposition, the analysis of differences in spatial contamination will allow a better understanding of the mechanisms of transfer and accumulation of these particles in ecosystems.
Different samples were taken from the outlets of the glaciers, at the foot of the massif, in France, Switzerland and Italy.
SAMPLE COLLECTION AT THE MONT-BLANC SUMMIT
In addition to samples taken from glaciers, samples were taken at the top of Mont-Blanc.
