Standard Test Method for Determination of Per- and Polyfluoroalkyl Substances (PFAS) in Soil/Biosolid Matrices by Solvent Extraction, Filtering, and Followed by Liquid Chromatography Tandem Mass Spectrometry (LC/MS/MS)

Importancia y uso:

5.1 PFAS are widely used in various industrial and commercial products; they are persistent, bio-accumulative, and ubiquitous in the environment. PFAS have been reported to exhibit developmental toxicity, hepatotoxicity, immunotoxicity, and hormone disturbance. PFAS have been detected in soils, sludges, surface, and drinking waters. This is a quick, easy, and robust method to quantitatively determine these compounds at trace levels in soil/biosolid matrices.

5.2 This test method has been validated using four ASTM reference soils (CH-1, ML-1, CL-1, and SP-1). ASTM reference soil CH-1 is Fat Clay (CH)—Vicksburg Buckshot Clay; ASTM reference soil ML-1 is silt (ML)—Vicksburg silt; ASTM reference soil CL-1 is lean clay (CL)—Annapolis clay; and ASTM reference soil SP-1 is sand (SP)—Frederick sand and four biosolids (Missouri, California, Idaho, and Georgia). Refer to the Precision and Bias (Section 17).
