New PFAS reference materials for environment and consumer products
- Per- and polyfluoroalkyl substances (PFAS) are a large group of emerging organic pollutants that contaminate the environment, food, and consumer products. They have a wide range of applications due to their water- and oil-repellent properties, as well as their chemical and thermal stability. However, the use of PFAS has raised concerns due to their persistence in the environment and their adverse health effects, leading to regulations aimed at controlling their use and minimizing exposure. Substances such as PFOS, PFHxS, and PFOA are listed in the Stockholm Convention on Persistent Organic Pollutants (POP Regulation, EU 2019/1021). Maximum levels have been set for PFAS in environmental matrices such as soil and water, but also for textiles as a relevant area of circular economy.
Reliable PFAS analysis leads to an increasing global demand for certified reference materials (CRM). However, CRMs for PFAS in soils and textiles are rare or currently not available.

Reliable PFAS analysis leads to an increasing global demand for certified reference materials (CRM). However, CRMs for PFAS in soils and textiles are rare or currently not available. To improve the metrological infrastructure and support PFAS measurements, two CRMs for PFAS in soil (BAM-U027) and PFAS in textiles (BAM-B003) based on ISO 17034 and ISO 33405 were developed. This poster provides an overview of the different steps for the preparation and characterization of these two reference materials. The assignment of the certified mass fractions for relevant PFAS targets (18 PFAS compounds for BAM-B003) is based on isotope dilution HPLC-MS/MS at three independent workplaces. The results of the BAM in-house study on BAM-U027 were supported by an interlaboratory comparison study.…
