Several hundred people entered the site of the chemist Arkema in Pierre-Bénite (Rhône) on Saturday to denounce perfluorinated (PFAS) pollution. The Rhône prefecture reported eight arrests, but “the CRS intervention was still in progress” in the middle of the afternoon.

In recent months, several communities and individuals have been concerned about “alarming concentrations” of perfluo pollution. If exposed over a long period, they can have effects on fertility or promote certain cancers.
