Evaluering
Investigation of outdoor textiles with respect to determine the content of ionic perfluorinated substances (PFASs) evaluation of results
NILU has, on behalf of the Norwegian Environment Agency, determined the concentration of ionic perfluorinated substances (PFASs), including PFOA, in outdoor clothing. Of the investigated 12 items, PFAS was only detected in 2 of the items. Four samples contained PFOA exceeding the limit of 1 μg/m2. The quality assurance where three replicates of one sample were extracted, had a relative standard deviation (RSD) less than 10% for all detected substances except one (PFTrDA). Other quality measures such as recovery calculations and blanks, show that the method used for extraction is suitable for these types of matrixes and substances. PFOS was not present in any of the items investigated, indicating that the textile industry manages to effectively avoid PFOS in their production processes.
