Poly- and perfluoroalkyl substances (PFAS) are a large heterogeneous group of chemicals consisting of several hundred different structures. PFAS are used in various applications, due to their stability and water/lipid repellent properties. PFAS can be used in the production of non-stick cookware, stain-resistant products or paper fast-food packaging. However, because of their persistence and bioaccumulation, these substances are omnipresent in the environment. Unfortunately, many of them present concern for human health. Therefore, food packaging testing should be done to monitor for PFAS.
PFAS could end up in the human body through various sources, but one major pathway is through food consumption.1 Correspondingly, in recent years a lot of focus was also put on food packaging testing for the analysis of PFAS.
Recently some PFAS have begun being regulated or phased out. Only a few of the substances have been risk assessed by the European Food Safety Authority (EFSA) and the US Environmental Protection Agency (EPA).2,3 There are various regulatory initiatives that specify acceptable limits of some PFAS; however, these are mainly imposed for environmental matrices.
Currently, more than 5,000 different PFAS are present on the market, with different physical and chemical properties. Furthermore, there are numerous precursors, many with unknown structures, making their analytical determination quite challenging.
In this webinar, the featured speaker will give a general overview of current findings of PFAS in food packaging. Additionally, the targeted approach for detecting and quantifying PFAS in paper and board matrices using high-performance liquid chromatography coupled with triple quadrupole mass spectrometry (HPLC-QQQ-MS) will be presented. Furthermore, the possible challenges associated with PFAS analysis and potential solutions will be discussed.
The model presented in this webinar could lead to an establishment of a simple and efficient method for PFAS quantification. This method could be used to monitor PFAS in paper-based food contact materials that are currently available in the market.
