The effect of weathering on per- and polyfluoroalkyl substances (PFASs) from durable water repellent (DWR) clothing
To assess the effects of weathering on per- and polyfluoroalkyl substances (PFASs) from durable water repellent (DWR) clothing, thirteen com. textile samples were exposed to elevated ultra violet (UV) radiation, humidity, and temperature in an aging device for 300 h, which mimics the lifespan of outdoor clothing. Before and after aging, the textile samples were extracted and analyzed for the ionic PFASs (perfluoroalkyl acids (PFAAs), perfluorooctane sulfonamide (FOSA)) and volatile PFASs (fluorotelomer alcs. (FTOHs), acrylates (FTACs) and methacrylates (FTMACs)). Results showed that weathering can have an effect on PFASs used in DWR of outdoor clothing, both on the PFAS profile and on the measured concentrations In most weathered samples the PFAA concentrations increased by 5- to more than 100-fold, while PFAAs not detected in the original textiles were detected in the weathered samples. DWR chemistries are based on side-chain fluorinated polymers. A possible explanation for the increase in concentration of the PFAAs is hydrolysis of the fluorotelomer based polymers (FTPs), or degradation of the FTOHs, which are used in the manufacturing of the FTPs. The concentrations of volatile PFASs also increased, by a factor up to 20. Suggested explanations are the degradation of the DWR polymers, making non-extractable fluorines extractable, or the transformation or degradation of unknown precursors. Further research is needed to unravel the details of these processes and to determine the transformation routes. This study shows that setting maximum tolerance limits only for a few individual PFASs is not sufficient to control these harmful substances in outdoor clothing.

Its molecular formula is C8H5F13O and its molecular weight is 364.1 g/mol. The purity is usually 95%.
1H,1H, 2H, 2H-Tridecafluoro-1-n-octanol is a material used to improve nanotube composites. It is also used in the synthesis of a recyclable fluorous hydrazine carbothioate compound with NCS to catalyze the acetalization of aldehydes.
1H,1H,2H,2H-Tridecafluoro-1-n-octanol is a potent and selective halogenated hydrocarbon. It binds to DNA at the dinucleotide phosphate site, which is an important site for polymerase chain reaction (PCR) activation. 1HFN has been shown to be more effective than other halogenated hydrocarbons in vitro assays on rat liver microsomes. It has been used as an additive in wastewater treatment to remove organic contaminants and metal ions. In vivo studies have been carried out in CD-1 mice to determine the effects of 1HFN on the liver and kidneys; these studies showed no toxicological effects on these organs. 1HFN also has been shown to inhibit enzymes such as cytochrome P450 and monoamine oxidase B that are involved in drug metabolism and may lead to adverse reactions with drugs metabolized by these enzymes., 647-42-7.
