Per- and polyfluorinated substances in the Nordic Countries

Temporal trends of suspect- and target-per/polyfluoroalkyl substances (PFAS), extractable organic fluorine (EOF) and total fluorine (TF) in pooled serum from first-time mothers in Uppsala, Sweden, 1996–2017

“…Few data are available on FTS temporal trends but a recent report highlighted the widespread occurrence of FTSs in the Nordic environment, including sediment, groundwater, indoor dust and biota. 35 FTSs generally occur at low concentrations with the exception of samples collected close to sites contaminated with AFFF. To the best of our knowledge, FTSs have not been reported previously in human serum from the Nordics; however, serum collected in 2009 from 50 individuals from the US contained 8:2 FTS at concentrations ranging from <0.005-0.231 ng mL À1 (detection in >95% of samples) and 6:2 FTS at concentrations ranging from <0.005-0.047 ng mL À1 (detection in >54% of samples).…”

Polyfluorinated Alkyl Phosphate Ester Surfactants – Current Knowledge and Knowledge Gaps

“…diPAPs were found in 57% (42 of 74) of selected samples of food packaging taken from Danish, Swedish and Canadian retailers [22], and PAPs therefore constitute a class of compounds to which human beings are exposed. In a recent study, diPAPs were reported to represent more than 91% of the total measured fluorinated compounds in indoor dust samples (mean ∑diPAPs concentration above 7 lg/g dust), indicating that indoor dust may as well be a potential source of human exposure [16].…”
