Article Synopsis
- - The study addresses the issue of accurately measuring total fluorine in plastic packaging to identify harmful PFAS, focusing on how talc inorganic filler can interfere with these measurements and cause false positives.
- - A method was developed by combining talc with polypropylene and measuring total fluorine using innovative techniques like oxidative pyrohydrolytic combustion ion chromatography and near-infrared spectroscopy.
- - Results showed a strong linear relationship between talc concentration and the total fluorine signal, underscoring the importance of this method for ensuring regulatory compliance in plastic products containing talc fillers.
Various testing methods and techniques have been used to identify and quantify per- and polyfluoroalkyl substances (PFAS) in food packaging. A common indirect measurement of PFAS is total fluorine (TF) and total organic fluorine (TOF). These methods are critical in rapidly screening food packaging materials for the >9000 PFAS and are often globally used for regulatory limits.
