Description: Many per- and polyfluorinated substances (PFAS) are subject to various restrictions in the European Union. For example, PFOS, PFOA, PFNA and PFHxS are subject to the maximum levels in selected foods introduced in the Contaminants Regulation (EU) 2023/915. Commission Recommendation (EU) 2022/1431 also recommends monitoring the presence of other PFAS in food, including PFDA, PFBS and PFOSA. This proficiency testing offers you the opportunity to check your analyses of a large number of PFAS.
