SETAC North America 2024 -- Per- and polyfluoroalkyl substances (PFAS) are a class of synthetic organofluorine compounds that have become a concern due to their persistence in the environment following extensive use over the last few decades. Due to their high degree of chemical stability as well as their widespread use, PFAS compounds are increasingly being detected in the environment and appear to persist for extended periods of time. Furthermore, exposure to these chemicals in everyday objects such as packaging and cookware, as well as within certain areas of industry, has led to the apparent bioaccumulation in certain areas of the population. Because of the concerns over health and environmental issues associated with PFAS chemicals, there has been a need to be able to monitor the occurrence of these materials in food commodities. The work described in this poster was a project to develop and validate an LC-MS/MS method for the analysis of a “typical” suite of PFAS analytes in fruit (strawberries and grapes), fruit processed commodities (jam and wine) as well as in fish tissues (edible muscle fillet). A simple and robust method was required, that could be easily applied to routine analysis at low concentrations, using commonly available equipment and approaches.
