Abstract

The National Institute of Standards and Technology (NIST) has a wide range of Standard Reference Materials (SRMs) which have values assigned for legacy organic pollutants and toxic elements. Existing SRMs serve as homogenous materials that can be used for method development, method validation, and measurement for contaminants that are now of concern. NIST and multiple groups have been measuring the mass fraction of a group of emerging contaminants, perfluoroalkyl acids (PFAAs), in a variety of SRMs. Here we report levels determined in an interlaboratory comparison of up to 23 PFAAs determined in five SRMs: sediment (SRMs 1941b and 1944), house dust (SRM 2585), soil (SRM 2586), and sludge (SRM 2781). Measurements presented show an array of PFAAs, with perfluorooctane sulfonate (PFOS) being the most frequently detected. SRMs 1941b, 1944, and 2586 had relatively low concentrations of most PFAAs measured while 23 PFAAs were at detectable levels in SRM 2585 Organics Contaminants in House Dust and most of the PFAAs measured were at detectable levels in SRM 2781 Domestic Sludge. The measurements made in this study were used to add values to the Certificates of Analysis for SRMs 2585 and 2781.
