Removal of Perfluorooctane Sulfonate (PFOS) and Related Compounds From Industrial Effluents
Perfluorooctane sulfonate (PFOS) and related perfluoroalkyl surfactants (PFAS) are ubiquitous contaminants of increasing public concern due to their environmental persistence, toxicity, and bioaccumulation. These perfluorinated compounds have been used for more than half a century in a wide variety …

Perfluorooctanoic Acid (PFOA) and Perfluorooctane Sulfonate (PFOS) in an Aquatic Ecosystem - Distribution and Fate
Perfluorooctanoate (PFOA) and perfluorooctane sulfonate (PFOS) belong to the family of perfluorinated surfactants (PFSs). They are widely distributed and persistent in the environment. For over 50 years, they have been used in numerous applications including paper and textile treatment, production …

Kinetics of alkali metal ion self-exchange on polystyrene sulfonate resin in dimethyl sulfoxide-water media
… metal cation self-diffusion in a polystyrene sulfonate ion exchange resin and in the external solution have been measured over a range of dimethyl sulfoxide (DMSO)-water mixtures from 0 to 70 mole % DMSO. Interpretation of results is simplified by the choice of this system which exhibits …

Taxonomic studies of two species of Peptococci and inhibition of Peptostreptococcus anaerobius by sodium polyanethol sulfonate
… anaerobius by sodium polyanethol sulfonate (SPS). Gelatin and protease peptone were found to protect Peptostreptococcus anaerobius from inhibition of growth by SPS, and, therefore, are useful additions to blood culture media for the purpose of enhancing isolation of …

Expression of perforin and granzyme variants in adult rat testes after ethylene dimethane sulfonate (EDS)-induced testosterone depletion
… produce testosterone. Using ethane dimethane sulfonate (EDS), a Leydig cell-specific toxicant, to deplete testosterone, we investigated the relationship between granzyme and perforin, and germ cell apoptosis. To confirm effects of testosterone depletion, EDS-treated rats were compared with …
