What is PFBS used for?
PFBS has been used as a surfactant in industrial processes and in water-resistant or stain-resistant coatings on consumer products such as fabrics, carpets, and paper. 1,2 The 3M Company has been a major manufacturer of PFBS and products containing PFBS.
What is GenX toxicant?
GenX is a trade name for a processing aid technology used to make high-performance fluoropolymers without the use of perfluorooctanoic acid (PFOA).
Is GenX regulated by the EPA?
EPA’s final chronic RfD for GenX chemicals is lower than the 2016 RfDs for PFOA and PFOS (Table 2). However, EPA is currently reevaluating toxicity information for PFOA and PFOS which could lead to changes to the 2016 RfDs.
Is GenX a Pfos?
PFOA and PFOS are the most studied PFAS chemicals and have been voluntarily phased out by industry, though they are still persistent in the environment. There are many other PFAS, including GenX chemicals and PFBS in use throughout our economy.
Is Perfluorobutane toxic?
Based on the above data, PFBS is considered practically non-toxic in multi-generation reproduction.
What is GenX PFAS?
GenX is a member of a large group of man-made chemical compounds known as per- and polyfluoroalkyl substances (PFAS). PFAS are man-made chemicals that do not occur naturally in the environment. These chemicals have broad uses in commercial products such as food packaging, nonstick coatings, and firefighting foam.
What are GenX and PFBS?
GenX chemicals and PFBS are man-made, fluorinated organic chemicals that are part of a larger group referred to as per- and polyfluoroalkyl substances (PFAS).
Is GenX a PFAS?
GenX is a member of a family of chemical compounds know as per- and polyfluoroalkyl substances (PFAS).
How do you remove GenX from water?
Preliminary research suggests that the best method to remove GenX from water is with a reverse osmosis filter system. Filtering water through activated charcoal or activated carbon has not been proven effective at removing GenX.
Is PFBS toxic?
PFBS is part of a family of environmentally persistent chemicals called per- and polyfluoroalkyl substances (PFAS), many of which are toxic. PFBS has been detected widely in drinking water, wastewater, and food packaging, according to the EPA.
Is Perfluorobutane safe to inhale?
b) Inhalation: No irritation or anaesthetic effects. c) Skin Contact: Non-irritating but hot liquid or vapour may cause thermal burns. d) Eye Contact: Non-irritating but hot liquid or vapour may cause thermal burns.
Is GenX used in Teflon?
GenX chemicals are used as replacements for PFOA for manufacturing fluoropolymers such as Teflon, since PFOA and related compounds have been found to be toxic and carcinogenic.
What is PFAS PFBS (PFAS)?
PFBS is one of the dominating and increasing PFAS in various environmental compartments away from point sources: Occurrence was reported in surface water, groundwater, drinking water (including tap water and bottled water), marine water and biota.
What is PFBS and why is it so dangerous?
The fact that PFBS and its salts were introduced into the market as a replacement chemical for PFOS-substances points to a bigger, very common problem: restricted hazardous chemicals are replaced by similar substances which are often identified as harmful some time later.
What is the difference between PFOS and PFBS?
PFAS are synthetic chemicals used in a wide range of products because of their ability to repel water, grease, and oil. PFBS has been used as a replacement chemical for PFOS.
Who can use the PFBS toxicity assessment?
EPA, federal agencies, states, tribes, and local communities can use the PFBS toxicity assessment, along with specific exposure and other relevant information, to determine if and when it is necessary to take action to address potential health risks associated with human exposures to PFBS under appropriate regulations and statutes.
