Project

RiverPlast

Goal: The Riverplast project is a participatory science project about freshwater microplastics.
It is based on citizen volunteering willing to invest in active research. The volunteers take samples, using the net "babylegs" [ developed by Max Liboiron in Canada] in the surface waters of rivers where they practice their activities. They send their samples to the Microplastics Observatory, La Pagaie Sauvage [2] and are then sent to a laboratory.
The goal is to be able to quickly, thanks to the multitude of samples, to have a first mapping of the situation of microplastics present in the freshwaters bodies in France.
Once in the laboratory, the inorganic / organic and mineral fractions are separated, then after observation and validation by optical microscopy, the microplastics are analyzed by infrared spectroscopy by m-FTIR or by ATR-FTIR. Under these conditions, we reach a resolution of about one hundred micrometers for the determinations

Methods: Manta, Citizen Participation, Citizen Science, micro-FTIR, FTIR-ATR, DIY methods, babylegs

Comment développer des outils simples et abordables qui pourraient être comparables aux méthodes standardisées afin de maximiser le nombre d'échantillon grâce au sciences participatives ? Le filet Babylegs est un dispositif artisanal composé d'une bouteille en plastique coupée à chaque extrémité pour l'ouverture, prolongée par des collants de bébé en guise de filet. L'amélioration de ce système permettra la collecte des microplastiques (MPs) en eaux douces et le partage de résultats exploitables accessibles à tous Le but du projet est de comparer, pour la 1èrefois, un outil scientifique (le filet Manta) et le filet Babylegs dans l’échantillonnage de MPs en eau douce
