Interlaboratory comparison study for PFAS analysis in soils and eluates

  • PFAS (per- and polyfluoroalkyl substances) comprise more than 10,000 compounds that have been used in various industrial and consumer products for decades. However, PFAS represent a growing problem because of their persistence in the environment and their adverse health effects. Therefore, reliable PFAS analysis of environmental compartments is indispensable but poses a complex challenge due to the large number of individual compounds in widely varying concentrations. The investigation and assessment of PFAS contamination in soil, as well as the determination and monitoring of necessary remediation measures, require comparable and high-quality standards in chemical analysis. Interlaboratory comparison studies (ILCs) are suitable tools to ensure these quality standards. Thus, an ILC involving 17 participating laboratories in Germany was organized and conducted by BAM, SenMVKU, and BImA in 2024 to determine PFAS in real soil samples (solid matter and eluates).

Essential results of the ILC will be presented focusing on analytical issues related to the HPLC-MS/MS determination of the PFAS target compounds based on current regulations but also alternatives such as GenX and Capstone A/B. Furthermore, unexpectedly observed effects interfering with the quantification of specific PFAS will be discussed.zeige mehrzeige weniger
