The Nordic Council of Ministers has recently published the report that Milieu has been working on for the past months: “PFAEs: Per- and polyfluoroalkylether substances: identity, production and use”. In close collaboration with one of the most prominent scientists in the field, Dr Zhanyun Wang, we looked at this sub-group of PFAS chemicals, trying to gather information on their identity, production and use in different industries. A better understanding of these chemicals will improve their management. We are proud to contribute to this very important discussion on one of the most relevant but overlooked chemical substance groups in recent history.
