Measurement of Per- and Polyfluoroalkyl Substances in Graminaceous plants using three extraction techniques

Dataset contains measured concentrations of PFAS analytes and limits of detection/quantification for 37 total samples. There are 82 total PFAS analytes (7 non-extracted internal standards, 24 extracted internal standards, and 51 target native analytes) and each individual sample has been quantified for all 82 of these compounds. Samples are extracts of plant tissues from three sources: Tucker Prairiegrass (a mix of orchardgrass and switchgrass collected from Tucker Prairie outside of Columbia, MO), dried switchgrass hay, and whole switchgrass vegetation (the latter two provided by Jason Masoner from the USGS Oklahoma-Texas Water Science Center). These three sample types have been extracted using three different extraction procedures: the novel hypothesized method of PFAS extraction in plants, a method based on a procedure reported in Nassazzi, 2022, and a third method based on a procedure reported in Zhao, 2024 as part of an Agilent Technologies Application Note. This study evaluates the extraction performance of each of these three methods across different plant matrices.
