Background:

National Institute of Standards and Technology (NIST) provides Standard Reference Materials (SRMs) for various analytes.
Existing SRMs are crucial for developing, validating, and performing measurements of contaminants.
Emerging contaminants, such as polyfluorinated substances (PFASs), require accurate quantification in environmental matrices.

Purpose of the Study:

To quantify the mass fraction of up to 23 polyfluorinated substances (PFASs) in five different NIST Standard Reference Materials (SRMs).
To establish certified values for PFASs in house dust (SRM 2585) and sludge (SRM 2781) SRMs.
To support the accurate measurement and monitoring of emerging contaminants in environmental samples.

Main Methods:

An interlaboratory comparison was conducted to measure PFASs.
Measurements were performed on five distinct SRMs: sediment (SRMs 1941b, 1944), house dust (SRM 2585), soil (SRM 2586), and sludge (SRM 2781).
Various analytical techniques were employed to determine the mass fraction of individual PFASs.

Main Results:

A range of PFASs were detected across the analyzed SRMs.
Perfluorooctane sulfonate was the most frequently detected PFAS.
SRM 2585 (house dust) and SRM 2781 (sludge) showed detectable levels of 23 and most measured PFASs, respectively, leading to the addition of values to their Certificates of Analysis.

Conclusions:

The study successfully quantified multiple PFASs in diverse environmental matrix SRMs.
The findings contribute to the accurate characterization of SRMs for emerging contaminants.
Certified values for PFASs in SRMs 2585 and 2781 will enhance the reliability of environmental measurements.
