There is increasing evidence that the ∼20 routinely monitored perfluoroalkyl and polyfluoroalkyl substances (PFASs) account for only a fraction of extractable organofluorine (EOF) occurring in environment. To assess whether PFAS exposure being underestimated marine mammals from Northern Hemisphere, we performed fluorine mass balance on liver tissues 11 different species using combination targeted analysis, EOF total determination, suspect screening. Samples were obtained east coast United...
Fluorine mass balance studies have shown that monomeric per- and polyfluoroalkyl substances (PFAS) with perfluoroalkyl chain lengths of ∼5–14 carbon atoms (i.e., "conventional" PFAS) account for a fraction (∼2%) the extractable organic fluorine (EOF) in municipal wastewater treatment plant (WWTP) sludge. The identity remaining EOF has thus far been unclear but may be partly attributable to fluorine-containing pharmaceuticals pesticides used throughout society. To test this hypothesis, we...
The high proportion of unidentified extractable organofluorine (EOF) observed globally in humans and the environment indicates widespread occurrence unknown per- polyfluoroalkyl substances (PFAS). However, efforts to standardize or assess reproducibility EOF methods are currently lacking. Here we present first interlaboratory comparison water sludge. Three participants (four organizations) analyzed unfortified PFAS-fortified ultrapure water, two groundwater samples, wastewater treatment...
It is generally accepted that per- and polyfluoroalkyl substances (PFASs) occur primarily in protein-rich tissues such as blood liver, but few studies have examined the occurrence of legacy novel PFASs lipid-rich blubber. Here we report distribution 24 PFASs, total fluorine, extractable organic fluorine (EOF) eight different a killer whale (Orcinus orca) from East Greenland. The sum target PFAS concentrations was highest liver (352 ng/g wet weight) decreased following order: > kidney ≈ lung...
Identification of novel PFAS, updating spatiotemporal trends and providing a framework for understanding white-tailed sea eagle PFAS exposure in Sweden.
The large number and diversity of organohalogen compounds (OHCs) occurring in the environment poses a grand challenge to analytical chemists. Since no single targeted method can identify quantify all OHCs, size OHC "iceberg" may be underestimated. We sought address this problem municipal wastewater treatment plant (WWTP) sludge by quantifying unidentified fraction iceberg using analyses major OHCs together with measurements total extractable (organo)halogen (TX EOX, respectively; where X =...
It is generally accepted that per- and polyfluoroalkyl substances (PFASs) occur primarily in protein-rich tissues such as blood liver, but few studies have examined the occurrence of PFASs (in particular emerging PFASs), lipid-rich blubber. Here we report distribution 24 PFASs, total fluorine (TF) extractable organic (EOF) eight different a killer whale ( Orcinus orca ) from East Greenland. The sum target PFAS concentrations was highest liver (352 ng/g ww) decreased order > kidney ≈ lung...

Fluorine mass balance studies have shown that monomeric per- and polyfluoroalkyl substances (PFAS) with perfluoroalkyl chain lengths of ~5-14 carbon atoms (i.e., “conventional” PFAS) account for a fraction (~2%) the extractable organic fluorine (EOF) in municipal wastewater treatment plant (WWTP) sludge. The identity remaining EOF has thus far been unclear, but may be partly attributable to fluorine-containing pharmaceuticals pesticides used throughout society. To test this hypothesis, we...
