DEVELOPING DETECTION METHODS FOR PFCS
Regarding the PFCs, a simplified and harmonized analytical procedure for the detection and quantification of Perfluorooctanesulfonate ( PFOS), perfluoro octane sulfonamide (FOSA), and perfluorooctanoic acid (PFOA) in food has been developed. WP1b is working on the in-house validation of a smart analytical method for perfluorinated compounds as well as on preparation of interlaboratory studies. It has been initiated the study of the concentration of PFCs in real canned fish samples by ICT-Prague. All analyzed samples were positively for PFCs with PFOS as the most concentrated analyte. In addition, the CSIC group has been assessed different real fish: fish muscle (n=15) and fish liver samples (n=12) from retail stores, working in triplicate. PFCs have been detected in 100 % of fish liver samples and in 93 % of fish muscle samples. Most of the PFCs have been found below the LOQ. Currently, a homogenization test is performed in collaboration with both WP partners and the first interlaboratory is under preparation.
