    Analyst 130:670-8. 2005
    ..5 h pressurized fluid extraction (PFE) in methanol reveals that the 24 h wrist action shaker yields the highest results. The 2 h wrist action shaker results are similar to those of the 1.5 h PFE extraction...

    Analyst 130:1299-302. 2005
    ..Detection and quantification limits as low as 100 pg cm(-2) were demonstrated. None of the fluoropolymer treated cookware samples analyzed showed detectable levels of PFOA when extracted under simulated cooking conditions...

    DuPont Haskell Laboratories, P O Box 50, Newark, Delaware 19714 0050, USA
    Anal Chem 77:6353-8. 2005
    ..The method utilizes an extraction solvent previously shown to release and recover aged residues of PFCAs. A confirmatory method using two precursor to product ions is also provided and demonstrated...

    Chemosphere 70:664-72. 2008
    ..The 7-3 Acid was not correlated with either PFCAs or PFAS, which suggests that it may have a different exposure pathway...

    Toxicology 220:203-17. 2006
    ..Based on these results, and for the endpoints evaluated in this study, the toxicological database developed primarily from testing linear/branched APFO is applicable to linear APFO...
