(FILES) A volunteer from the "Future Generations" association collects water samples from discharge from the Solvay factory, which manufactures PFAS molecules for the pharmaceutical and pesticide industries, in Salindres, southern France, on April 18, 2024. Samples are being taken, in particular around the Solvay chemical centre producing per- and polyfluoroalkyl substances, better known as PFAS, whose non-stick and impermeable properties are widely used in everyday consumer products, cookware, food packaging, waterproof textiles, cars or medicines.
