Perfluorooctane sulfonate toxicity, isomer-specific accumulation, and maternal transfer in zebrafish (Danio rerio) and rainbow trout (Oncorhynchus mykiss)Rainie L Sharpe
Department of Biological Sciences, University of Alberta, Edmonton, Alberta T5G 2E9, Canada
Environ Toxicol Chem 29:1957-66. 2010..1 +/- 7.6 microg/g). The isomer profile in eggs was not significantly different from that of adults, suggesting that the maternal transfer of branched and linear PFOS isomers in fish is largely nonisomer specific...

Perfluorinated acid isomer profiling in water and quantitative assessment of manufacturing sourceJonathan P Benskin
Department of Laboratory Medicine and Pathology, University of Alberta, Edmonton, AB, Canada
Environ Sci Technol 44:9049-54. 2010..Overall, these data suggest that, with the exception of Tokyo Bay, ECF manufacturing has contributed to the bulk of contamination around these source regions, but other sources are significant, and remote sites should be monitored...
Exceptionally high serum concentrations of perfluorohexanesulfonate in a Canadian family are linked to home carpet treatment applicationsSanjay Beesoon
Division of Analytical and Environmental Toxicology, Department of Laboratory Medicine and Pathology, University of Alberta, Edmonton, AB, Canada
Environ Sci Technol 46:12960-7. 2012..The high PFHxS and moderately high PFOS concentrations in serum and household samples are consistent with the known PFAS content of certain Scotchgard formulations, and exposure was likely through dust ingestion and/or inhalation...
Source elucidation of perfluorinated carboxylic acids in remote alpine lake sediment coresJonathan P Benskin
Division of Analytical and Environmental Toxicology, Department of Laboratory Medicine and Pathology, University of Alberta, Edmonton, Alberta T6G 2G3, Canada
Environ Sci Technol 45:7188-94. 2011..The efficacy of recent industry phase-out initiatives was difficult to assess due to the divergent temporal trends in samples after 2003; thus, continued monitoring is suggested at remote sites such as these...
Disposition of perfluorinated acid isomers in Sprague-Dawley rats; part 1: single doseJonathan P Benskin
Division of Analytical and Environmental Toxicology, Department of Laboratory Medicine and Pathology, University of Alberta, Edmonton, Alverta, Canada
Environ Toxicol Chem 28:542-54. 2009..Source assignment based on PFA isomer profiles in biota must therefore be conducted with caution, because isomer profiles are unlikely to be conserved in biological samples...
