Levels and trends of poly- and perfluorinated compounds in the arctic environmentCraig M Butt
Department of Chemistry, University of Toronto, Toronto, Ontario, Canada
Sci Total Environ 408:2936-65. 2010..In contrast, ringed seals and polar bears from Greenland continue to show increasing PFOS concentrations. The inconsistent temporal trends between regions may be representative of differences in emissions from source regions...
Spatial trends of perfluoroalkyl compounds in ringed seals (Phoca hispida) from the Canadian ArcticCraig M Butt
Department of Chemistry, University of Toronto, Toronto, Ontario, Canada
Environ Toxicol Chem 27:542-53. 2008..After adjusting for delta13C values, concentrations of most PFCs generally were statistically greater in the Grise Fiord, Qikiqtarjuaq, Arviat, and Nain populations...
Prevalence of long-chained perfluorinated carboxylates in seabirds from the Canadian Arctic between 1975 and 2004Craig M Butt
Department of Chemistry, University of Toronto, 80 St George Street, Toronto, Ontario M5S 3H6, Canada
Environ Sci Technol 41:3521-8. 2007..Finally, the detection of the 8:2 and 10:2 FTUCAs in seabirds is suggestive of fluorotelomer alcohols as a source of some PFCAs...
Elucidating the pathways of poly- and perfluorinated acid formation in rainbow troutCraig M Butt
Department of Chemistry, University of Toronto, Toronto, Ontario M5S 3H6, Canada
Environ Sci Technol 44:4973-80. 2010..Alternatively PFOA could be formed directly through the beta-oxidation of the 7:3 beta-keto acid...
Biotransformation of the 8:2 fluorotelomer acrylate in rainbow trout. 2. In vitro incubations with liver and stomach S9 fractionsCraig M Butt
Department of Chemistry, University of Toronto, 80 St George Street, Toronto, Ontario M5S 3H6, Canada
Environ Toxicol Chem 29:2736-41. 2010..These trends demonstrate the potential for considerable extrahepatic metabolism of the 8:2 FTAc before uptake into the internal tissues, ultimately limiting the overall bioaccumulation...
Biotransformation of the 8:2 fluorotelomer acrylate in rainbow trout. 1. In vivo dietary exposureCraig M Butt
Department of Chemistry, University of Toronto, 80 St George Street, Toronto, Ontario M5S 3H6, Canada
Environ Toxicol Chem 29:2726-35. 2010..The results of the current study demonstrated a scenario in which a biologically labile compound is biotransformed to terminal metabolites that are much more biologically persistent...
Spatial distribution of perfluoroalkyl contaminants in lake trout from the Great LakesVasile I Furdui
Department of Chemistry, University of Toronto, 80 St George Street, Toronto, Ontario, M5S 3H6
Environ Sci Technol 41:1554-9. 2007..The 10:2 FTUCA was detected only in 9% of all samples (nd, 45 pg g(-1)). For those PFCs where we determined lake water concentrations, the highest log BAFs were calculated for PFOS (4.1), PFDA (3.9), and PFOSA (3.8)...
Atmospheric chemistry of 4:2 fluorotelomer acrylate [C4F9CH2CH2OC(O)CH=CH2]: kinetics, mechanisms, and products of chlorine-atom- and OH-radical-initiated oxidationCraig M Butt
Department of Chemistry, 80 St George Street, University of Toronto, Toronto, Ontario, Canada M5S 3H6
J Phys Chem A 113:3155-61. 2009..The atmospheric oxidation of fluorotelomer acrylates is a potential source of perfluorinated carboxylic acids in remote locations...
Rapid response of Arctic ringed seals to changes in perfluoroalkyl productionCraig M Butt
Department of Chemistry, University of Toronto, 80 St George Street, Toronto, Ontario M5S 3H6, Canada
Environ Sci Technol 41:42-9. 2007..Further, the relatively short doubling times of the PFCAs and PFOS disappearance half-lives support the hypothesis of atmospheric transport as the main transport mechanism of PFCs to the arctic environment...
