Recently we sat down with Xenia Trier, one of the co-authors of the Madrid Statement on perfluorinated alkyl substances (PFAS), a group of chemicals which accumulate in the environment, and are known to have harmful effects on humans. She explains what the Madrid Statement actually is, what is its purpose, and why it is important, while also providing some background on what PFAS are.

Xenia is an analytical chemist who works at the Techincal University of Denmark analysing the presence of PFAS in food contact materials, and the extent to which it migrates into our food. The Madrid Statement follows on from the Helsingør Statement (which she also co-authored), which was a more technical paper outlining the why of our concern over PFAS chemicals, but was intended for a technical audience. The Madrid Statement goes further, giving a roadmap for concrete actions and priorities for a number of relevant stakeholders, including government, manufacturers, and end-consumers.
