ABSTRACT
Per- and polyfluoroalkyl substances (PFAS) are ubiquitous, harmful contaminants impacting the environment. PFAS pervade aquatic ecosystems and can bioaccumulate in fish; therefore, consumption of PFAS-contaminated fish is of critical concern for public health. Analysis of PFAS in fish can be challenging due to difficult and time-consuming sample preparation, separation of interferents (e.g., bile salts), and low limits relevant to public health protection goals. New research into PFAS occurrence has expanded targeted analysis for PFAS of environmental relevance beyond the analytes historically included in standardized methods, such as EPA 1633. Over 40 PFAS, expanding from the target list included in EPA 1633, were rapidly extracted from soil and fish tissue using the EDGE PFAS System by CEM and analyzed using Shimadzu LCMS. Quality control criteria as defined by EPAM1633A were within acceptable ranges for all standards and controls. This presentation will demonstrate the benefits of automated sample preparation and robust, sensitive instrumentation for PFAS analysis.
