What is Perfluorohexane sulfonate used for?

What is Perfluorohexane sulfonate used for?

PFHxS is a chemical used as a surfactant in a variety of industrial and commercial products such as food packaging, stain and water-resistant materials, fire-fighting foams and paint additives.

Where is PFHxS found?

PFHxS has been detected in groundwater in private drinking water wells and public drinking water systems in several parts of Minnesota where known industrial use or disposal of PFAS occurred. PFHxS has been detected in public drinking water at levels up to 0.57 parts per billion (ppb).

Are PFAS surfactants?

PFAS applications have made use of their unique surfactant properties. Their alkyl tails make these substances both hydrophobic (water-repelling) and oleophobic/lipophobic (oil/fat-repelling). Because of these properties, PFASs have been used extensively in surface coating and protectant formulations.

What is short chain PFAS?

Short- chain PFAS have fewer carbons such as perfluorobutanoic acid (PFBA). Long- and short-chain PFAS were manufactured, but they can also be the result of degradation of more complex PFAS. History and Use. PFAS are a complex family of several thousand. compounds that have been produced since the late.

What is Pfhxs in water?

Perfluorohexane sulfonate is a member of a group of perfluorinated chemicals used in many consumer products. Perfluorinated chemicals can cause serious health effects, including cancer, endocrine disruption, accelerated puberty, liver and immune system damage, and thyroid changes.

Is Teflon a PFAS?

Today, the family of compounds including Teflon, commonly called PFAS, is found not only in pots and pans but also in the blood of people around the world, including 99 percent of Americans. PFAS chemicals pollute water, do not break down, and remain in the environment and people for decades.

Is PFAS organic or inorganic?

organic chemicals
PFAS is a broad category of organic chemicals that have been used for an assortment of industrial and consumer products since the 1950s.

Is C6 a PFAS?

Another major type of PFAS in use today is C6 fluorotelomers, which are well-studied and meet relevant regulatory standards for the protection of human health and the environment.

How many types of PFAS are there?

4,700 types
It is estimated that there are over 4,700 types of PFAS worldwide. The EPA does not currently have lifetime health advisory levels for these other PFAS chemicals in drinking water.

What industries use PFAS?

PFAS are used in industries such as aerospace, automotive, construction, electronics, and military. PFAS molecules are made up of a chain of linked carbon and fluorine atoms. Because the carbon-fluorine bond is one of the strongest, these chemicals do not degrade in the environment.
