Analysis of Per- and Polyfluoroalkyl Substances (PFAS) in Food Samples by LC-MS/MS

Per- and Polyfluoroalkyl Substances (PFAS) is the collective name for a chemical group of organic fluorinated compounds, perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) are representative compounds of PFAS. They have been used water repellents, surface treatment agents, fire extinguishers, and coatings. PFAS are persistent and bioaccumulative in the environment because of their stable structure and known that they are present in a wide range of environmental water and wildlife. Due to concerns about human exposure through diet, studies on the status of food contamination by PFAS are being conducted in various countries. We have examined a quantitative analysis method for forty PFAS compounds in foods with two SPE cartridges.
