Experts on this family of synthetic chemicals worry initiative may be used by parties with ‘vested interests’
Twenty of the world’s top experts in per- and poly-fluoroalkyl substances (PFAS) have serious concerns about a project to redefine this family of synthetic chemicals, known for their persistence in the environment and linked to serious health problems, that is being led by the International Union of Pure and Applied Chemistry (Iupac).
