New PFAS Reference Materials for Environment and Circular Economy

  • Per- and polyfluorinated alkyl substances (PFAS) are a group of synthetic compounds that have been used in various industrial and consumer products for decades. Their wide range of applications is due to 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 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 values have been set for PFAS in environmental matrices such as soil and water, but also for textiles as a relevant area of circular economy and part of the current German standardization roadmap “Circular Economy”. Reliable PFAS analysis requires an increasing global demand for certified reference materials (CRM).

Maximum values have been set for PFAS in environmental matrices such as soil and water, but also for textiles as a relevant area of circular economy and part of the current German standardization roadmap “Circular Economy”. Reliable PFAS analysis requires 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 preparation and characterization of the two candidate materials. The assignment of the certified mass fractions for relevant PFAS targets (18 PFAS targets for BAM-B003) is based 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.zeige mehrzeige weniger
