ISO 21675:2019 Solution/Mixtures
For over 30 years the European Union have worked tirelessly to protect the integrity of our drinking water. EU officials have recently reached a provisional agreement to update the Union's 1998 Drinking Water Directive to tighten up the permissible limits allowed for both PFAS and several other drinking water contaminants, including bisphenol-A, microplastics, lead and chromium. The at the time of writing the European Parliament and Council are still to formally approve the proposal.
European drinking water standards currently far exceed the standards set in the United States but this is a changing picture as state by state new instances of contaminants are emerging. Currently, the U.S. Environmental Protection Agency has only issued a nonenforceable health advisory of 70 ppt for PFOA, formerly used by DuPont to make Teflon, and PFOS, formerly an ingredient in 3M’s Scotchgard. Those compounds are no longer manufactured in the U.S., but they and other PFAS contaminate the drinking water for an estimated 110 million Americans. PFOA, PFOS and some other PFAS chemicals have been linked to cancer, thyroid disease, reproductive and immune system problems, and other health harms.
The european Parliament and the Council of the European Union have released new requirements for the analysis of per- and perfluoroalkyl substances (PFAS) in water intended for human consumption (5813/20). This amendment to Council Directive 98/83/EC included perfluoroalkanesulfonates that are not commercially available. In response to this Wellington Labroatories, Canada, is pleased to announce that its chemists have synthesized, purified, characterized and prepared accurate certified reference standards of the required substances: sodium perfluoro-1-undecanesulfonate (L-PFUds) and sodium perfluoro-1-tridecanesulfonate (L-PFTrDS). Wellington Laboratories have also prepared a native solution/mixture (EU-5813-NSS) that contains all of the PFAS listed in the drinking water directive (5813/20) for your convenience. This solution/mixture can be used in conjunction with two of Wellington's existing mass-labelled PFAS mixtures to easily prepare a calibration set for quantification.
