Gordon has proposed a tentative metabolic pathway for many of the N-alkylated perfluorooctane sulfonamides which consists of successive N-dealkylations leading to perfluorooctane sulfonic acid as the final common metabolite (Fig. 1).

Reactive oxygen species (ROS) can induce DNA damage that, if unrepaired, may lead to disruption of gene transcription as well as to interference with DNA methylation [5, 6].

Objection is made to these requests on the grounds that they seek information which is not relevant or reasonably calculated to lead to the discovery of admissible evidence.

LABORATORY-SCALE THERMAL DEGRADATION OF PERFLUOROOCTANYL SULFONATE AND RELATED SUBSTANCES TEST SUBSTANCE Identity: Perfluorooctanesulfonate; may also be referred to as PFOS or C8F17SO3-K+. (1-Octanesulfonic acid, 1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-heptadecafluoro-, potassium salt, CAS # 2795-39-3).

The first, based in the social sciences, was Armstrong's 1982 article13 that reviewed research on science journals and the editorial policies of leading journals, and then pre sented the implications and his recommendations for im provements.

Inhibition of HMG-CoA reductase also leads to a deficiency of mevalonate and isoprenoids such as dolichol, isopentyl adenine, ubiquinone, haem A and many proteins bound to famesyl and geranylgeranyl residues (Soma et a l, 1992; Brewer et al., 1993; Corsini et a l, 1995).

FILE NAME: National Safety Council (NSC) DATE: 2000 DOC#: NSC106 DOCUMENT DESCRIPTION: Historical Index to the Occupational Safety & Health Data Sheets INTRODUCTION This index has been developed by the Library of the National Safety Council to provide historical information on the Occupational Safety & Health Data Sheets, formerly known as the Industrial Data Sheets.

The mechanisms and pathways leading to the presence of PFOS in human blood are not well characterized but likely involved environmental exposure to PFOS or to precursor molecules and residual levels of PFOS or PFOS precursors in industrial and commercial products .

This seems like a rather awkward way to conduct these studies and leads to many questions.

Disposal of this water could lead to contamination of the aquatic environment.
