Determination of perfluorinated alkyl acids in corn, popcorn and popcorn bags before and after cooking by focused ultrasound solid–liquid extraction, liquid chromatography and quadrupole-time of flight mass spectrometry

• FUSLE and UHPLC–(QTOF)MS/MS of nine PFCAs and PFOS in corn, popcorn and packaging. • Complete extraction in one FUSLE cycle of only 10s. • Microwave popcorn bags and their content are analyzed before and after cooking. • PFAA levels from 3.50 to 750ng/g in packaging (mainly PFHxA). PFOA and PFOS n...
