| Description
| - Due to their properties perfluoroalkyl and polyfluoroalkyl substances are used for surface treatment of textiles, plastics and paper and board food contact materials to prevent them from being soiled or from soaking up fat or water. Their stability makes them convenient for high temperature applications, for instance when the foods in respective packaging are intended to be microwave heated. The perfluoroalkyl and polyfluoroalkyl substance based additives for the surface treatment of paper and board materials contain as side groups fluorotelomer alcohols, which can potentially split off. Although the occurrence of polyfluorinated surfactants in food contact materials represent health concern issue, there are only few studies dealing with analysis of such chemicals in paper and board and the penetration of fluorotelomer alcohols to food items. The aim of this study was to develop a simple and effective method for the determination of fluorotelomer alcohols in baking paper and other food contact materials. Simple, solvent free headspace solid phase microextraction technique was selected for analysis of volatile fluorotelomer alcohols. The main factors influencing the analytical process (fiber type, headspace volume, extraction time, temperature, sample amount, sample ionic strength and agitation speed) were investigated. The identification of analytes was performed with gas chromatography coupled to a mass spectrometric detector with a high resolution time-of-flight mass analyzer. Using StableFlex DVB/CAR/PDMS 50/30 ?m SPMEfiber the achieved limits of quantification were 2, 2,2and5ng/g of paper for 4:2, 6:2, 8:2 and 10:2 FTOHs, respectively.
