Screening programme 2014. Phosphites, selected PBT substances and non-target screening. NILU OR
The occurrence and environmental risk of a number of phosphites and selected PBT substances are reported for wastewater effluents and leachates, as well as sediments and biota from Oslofjord and Lake Mjøsa. In addition a suspect and non-target screening approach was applied to approximatley half of the biota samples.

NILU has on behalf of the Norwegian Environment Agency determined the concentration of ionic perfluorinated substances (PFASs), including PFOA, in outdoor gear.
Of the investigated 18 items, no PFAS could be detected at all in nine of them. Two 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 shows that the method used for extraction is suitable for these types of matrices and substances. PFOS was not present in the items investigated, indicating that the textile industry manages to effectively avoid PFOS in their production processes.
