Have the phase-outs of PFASs affected concentrations in the environment?

The manufacturing and use of some potentially harmful per- polyfluoroalkyl substances (PFASs) have been restricted or phased-out in some countries, but as these substances often are extremely persistent and may be transported over long distances it is not obvious what effect the regulatory actions have had on the concentrations in humans and in the environment. In a systematic review that is summarised here, Mistra EviEM has assessed the evidence for temporal trends in a global context.
