• Perfluoroalkyl acids in marine organisms from Lake Shihwa, Korea

  Published on January 9, 2009
  This is the first report of concentrations of perfluorooctanesulfonate (PFOS) and other perfluoroalkyl acids (PFAs) in marine organisms from the industrialized region of Korea.

• Acute and chronic effects of perfluorobutane sulfonate (PFBS) on the mallard and northern bobwhite quail

  Published on October 8, 2007
  To evaluate the potential hazard that PFBS may pose to avian species, acute dietary studies with juvenile mallards and northern bobwhite quail, as well as a quail dietary chronic study of reproduction were conducted.

• NMR studies of the thermal degradation of a perfluoropolyether on the surfaces of γ-alumina and kaolinite

  Published on July 18, 2007
  Solid-state nuclear magnetic resonance (NMR) methods are used to follow the thermal degradation of Krytox 1506, a common perfluoropolyether, following adsorption onto the surfaces of γ-Al2O3 and a model clay (kaolinite).

• Effects of perfluorooctane sulfonate on mallard and northern bobwhite quail exposed chronically via the diet

  Published on June 6, 2006
  Adult mallard ducks and northern bobwhite quail were exposed to 0, 10, 50, or 150mg perfluorooctane sulfonate /kg in the diet for up to 21 weeks.

• Pharmacokinetics and acute lethality of perfluorooctanesulfonate (PFOS) to juvenile mallard and northern bobwhite

  Published on February 2, 2006
  Concentrations of PFOS in juvenile mallard and quail liver associated with mortality are at least 50-fold greater than the single maximum PFOS concentration that has been measured in livers of avian wildlife.

• Inhibition of Gap Junctional Intercellular Communication by Perfluorinated Compounds in Rat Liver and Dolphin Kidney Epithelial Cell Lines in Vitro and Sprague-Dawley Rats in Vivo

  Published on August 1, 2002
  The effects of PFOS and related sulfonated fluorochemicals on gap junctional intercellular communication (GJIC) were studied using a rat liver epithelial cell line and a dolphin kidney epithelial cell line.

• Inhibition of gap junctional intercellular communication by perfluorinated fatty acids is dependent on the chain length of the fluorinated tail

  Published on January 6, 1999
  This study indicates that the determining factor of gap junctional intercellular communication (GJIC) inhibition was probably the fluorinated tail of PFFAs.
