  • Progress document - ECHA
    The basis for the proposed restriction is the fact that PFAS and their degradation products may persist in the environment for a very long period, longer than any other man-made chemical Further concerns are their bioaccumulation, mobility, long range transport potential (LRTP), accumulation in plants, global warming potential and (eco)toxicological effects The EU-wide risk arises from the
