perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) are man-made, perfluorosurfactants stable. The properties of perfluoroalkylated compounds that cause them to persist in the environment are also properties that make them attractive compounds for industrial use for more than 50 years.
Because of the unique properties of carbon-fluorine bond and polarity perfluoroalkyl group, a potential successor to replace perfluorinated surfactants in many cases continue to perfluoroalkyl-based. Thus, the problem of persistence in the environment. There is a need to examine emerging new replacement surfactant for biodegradability.
The study included measurement of decomposition of lively substitute perfluorinated surfactants. Stability replacement surfactant perfluorinated tested using an advanced process of oxidation, which is based on the degradation by ultraviolet light, hydrogen peroxide, or both, followed by conventional tests, including automated methods based on test manometric respirometry (OECD 301 F; OxiTop), test the closed-bottle (OECD 301 D), and a standard fixed-bed bioreactor in perfluorobutane sulfonate, fluorosurfactant Zonyl, two ester fluoraliphatic (Novec Novec FC-4430 and FC-4432), and 10- (trifluoromethoxy) decane 1 sulfonate.
Most of the new surfactants are well established in the market and have been used in some applications as an alternative to PFOA PFOS- and based surfactant. ready biodegradation test fluoroaliphatic ester, which fluorosurfactant Zonyl, perfluorobutane sulfonate, and 10- (trifluoromethoxy) decane-1-sulfonate using manometric respirometry test (OxiTop) does not meet the criteria for ready biodegradation test. However, 10- (trifluoromethoxy) decane-1-sulfonate was observed to be degradable when fixed-bed bioreactor test standards applied.

Description: p38 is a protein encoded by the MAPK14 gene which is approximately 41,2 kDa. p38 is localised to the cytoplasm and nucleus. It is involved in activated TLR4 signalling, the IL-2 pathway, toll-like receptor signalling pathways, the VEGF signalling pathway and 4-1BB pathway. This protein falls under the MAP kinase family. It acts as an integration point for multiple biochemical signals, and is involved in a wide variety of cellular processes such as proliferation, differentiation, transcription regulation and development. This kinase is activated by various environmental stresses and proinflammatory cytokines. p38 is expressed in the brain, heart, placenta, pancreas and skeletal muscle. Mutations in the MAPK14 gene may result in patellar tendinitis and lumbosacral lipoma. STJ94878 was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen. This polyclonal antibody detects endogenous levels of p38 protein.
