Action sought on poly and perfluoroalkyl substances by Nick Boley

A significant number of international scientists, across many disciplines, have drafted a statement “The Madrid Statement” which calls for much greater international cooperation concerning poly- and perfluoroalkyl substances (PFAS).

Amongst other things the statement calls for greater information on those chemicals used as substitutes for PFAS, to ensure that we are not replacing one group of toxic chemicals with another. There is specific concern about the use of polyfluorinated compounds as alternatives.

One of the more interesting parts of the statement is the call for the development of valid analytical methods for the “identification and quantification of additional families of PFASs, including fluorinated alternatives”. It is refreshing to note the inclusion of something on analytical measurements in a statement of this type, and affords proper recognition to the importance of analytical measurement methodology in monitoring of toxic chemicals in the environment, to underpin regulation and provide evidence of problems and issues.
