Per- and Polyfluoroalkyl Substances (PFAS) in Consumer Products: An Overview of the Occurrence, Migration, and Exposure Assessment.

Per- and polyfluoroalkyl substances (PFASs) have been widely used in the production of consumer products globally due to the excellent water and oil resistance and anti-fouling properties. The multiple toxic effects of some PFASs also pose a threat to human health and ecosystem, and the frequent use of certain consumer products increased the risk of human exposure to PFASs. More data on the occurrence, concentration, and migration of PFASs in consumer products is urgently needed to address the possible risks posed by exposure to consumer products.

Development of a procedure based on dispersive solid phase extraction and LC-MS/MS for the analysis of perfluoroalkyl and polyfluoroalkyl substances in food contact materials.

To monitor per- and polyfluoroalkyl substances (PFAS) in food contact materials (FCMs), an LC-MS/MS method for the simultaneous detection of 35 PFAS was developed and validated in paper and plastic products. Chromatographic and mass spectrometry parameters, extraction solvents, matrix effects in details were studied. The impact of matrix effects on PFAS concentration was analyzed, revealing that the matrix enhancement effect was more significant for some PFAS with low concentrations.
