Perfluorooctyl sulfonate

Some widely used fluorotensides have recently become the focus of environmental concerns. Compounds such as perfluorooctyl sulfonic acid and perfluoroocta-noic acid (PFOA) have environmental lifetimes on a nearly geological time-scale. Traces of these substances have been found to be present in the remotest locations on earth and the source of the contamination remains unclear. There is not yet much unambiguous evidence of negative physiological effects of these widely used fluorosurfactants, although perfluorooctyl carboxylates have attracted some critical attention as a potential developmental toxin in rats [37]. Some major producers have, therefore, already started to replace these tensides by more readily degradable alternative compounds. 

A new type of ionic PAGs based on imides and methides has recently been proposed by 3M. The notable characteristic of these PAGs is that they do not contain perfluorooctyl sulfonates and related derivatives, which have recently been identified by the U.S. Environmental Protection Agency and environmental regulatory agencies in other countries to pose health hazards, as they are biopersis-tent and toxic, and bioaccumulate in mammalian tissues. 

The first-generation 248-nm and 193-nm lithographic top antireflection coatings used perfluorooctyl sulfonate (PFOS) compounds, which have been determined to be toxic and persistent in the environment. Recently introduced top antireflection coatings are PFOS-free and are environmentally friendly. 

Charlie Auer, former Director of the EPA s Office of Pollution Prevention and Toxics, made a presentation in Ottawa, Ontario, Canada, on 30 October 2006 (Air and Waste Management Association) titled US Experience in Applying Informed Substitution as a Component of Risk Reduction and Alternative Analysis. In his presentation, Auer cited the use of highly fluorinated substances such as perfluorooctyl sulfonate (PFOS) and perfluorooctanoic acid (PFOA). He suggested that these substances...
