Perfluorooctane sulphonate (PFOS) ... belongs to a group of organic compounds, perfluorinated organic substances, which have the shared feature that all the hydrogen atoms, bound to the carbon chain, are exchanged for fluorine atoms. A reactive sulphonate group has been bound to one end of the carbon chain. Further chemical groups are bound to the sulphonate group so that various types of surface-active substances are formed. These substances may then in some cases be broken down to PFOS in nature. Altogether there are several hundred different compounds where PFOS forms part of the structure.  5, record 1, English, - perfluorooctanesulfonate

A large proportion of the PFOS produced forms part of polymers, where the final product may contain residues of fluorinated starting substances that have not or have only partially reacted. PFOS is used for surface treatment and as an impregnating agent in a number of products such as carpets, furniture, paper, textiles and leather. Other PFOS-like substances are used as surface-active substances e. g. in cleaning products.  5, record 1, English, - perfluorooctanesulfonate

EPA [Environmental Protection Agency] is proposing a supplemental significant new use rule (SNUR) under section 5(a)(2) of the Toxic Substances Control Act (TSCA) for the following 75 substances: Perfluorooctanesulfonic acid (PFOSH) and certain of its salts (PFOSS), perfluorooctanesulfonyl fluoride (POSF), certain higher and lower homologues of PFOSH and POSF, and certain other chemical substances, including polymers, that are derived from PFOSH and its homologues. These chemicals are collectively referred to as perfluoroalkyl sulfonates, or PFAS. ... In the original proposed SNUR, these chemicals were referred to collectively as perfluorooctylsulfonates, or PFOS, but commenters noted that this generic usage of the term PFOS was inconsistent with the use by the manufacturer, the Minnesota Mining and Manufacturing Company (3M), of PFOS to refer only to chemicals with an eight-carbon, or C8, chain length.  6, record 1, English, - perfluorooctanesulfonate

Microporous nonfibrous filter membrane... in the pores of which... an enzyme capable of bringing about a specific chemical alteration in a substrate has been crosslinked by means of a bifunctional coupling agent.... Enzyme membranes of this process are prepared by first impregnating the membrane pores with a suitable enzyme. This can be done either by forcing an enzyme solution through the pores of the membrane or by immersing the membrane in the enzyme solution for 3 to 10 hours, thereby allowing the enzyme molecules to diffuse into the pores of the membrane. The enzyme-loaded membrane is then immersed into a solution of a bifunctional crosslinking agent to effect the crosslinking of the enzyme in the membrane pores.  1, record 3, English, - crosslinked%20enzyme%20membrane

Lorsque les structures ainsi préparées demeurent solubles, on peut les inclure dans un gel. [...] - réticulation des molécules d'enzymes diluées par des molécules protéiques non actives, par exemple l'albumine, ce qui permet de diminuer l'effet dénaturant du pontage et de faire varier l'activité des complexes. [...] - les propriétés mécaniques des préparations précédentes laissant, en général, à désirer, on a procédé à la réticulation des molécules d'enzymes après adsorption ou imprégnation d'un support convenable. Dans le cas de supports poreux, l'augmentation de taille résultant du pontage intermoléculaire empêche l'enzyme de diffuser librement hors des pores.
