Association of Perfluorooctanoic Acid (PFOA) and Perfluorooctane Sulfonate ( PFOS) with age of puberty among children living near a chemical plant.

Because of their unique ability to repel oil and water, these chemicals have been used in: surface protection products such as carpet and clothing treatments; coatings for paper, cardboard packaging and leather products; industrial surfactants, Being able to test consumer products to for PFOA / PFOS to 1µg/m 2, enables Eurofins | BLC to provide greater support to customers with international chemical and product safety legislation compliance. Eurofins | BLC can carry out your PFOA / PFOS test in 3-5 working days. A … Chemical name: Ammoniumpentadecafluorootanoate (APFO) Molecular formula: C8F15O2NH4 CAS number 3825-26-1 Perfluorooctane sulfonic acid (PFOS) is the most prominent of the perfluoroalkane sulfonic acids (PFSAs). PFOS has a linear perfluoroalkyl carbon chain of 8 atoms and a sulfonic acid functional group (Danish EPA, 2013). Successful alternatives to PFOS materials have included non-perfluorinated chemicals such as hydrocarbon surfactants, chemicals with short perfluorinated chains (C3 - C4), silicones, telomers. In very few cases, it has been possible to reformulate coatings … Perfluorooctane Sulfonate (PFOS) and related chemical products – OECD webportal .

av BB Gump · 2011 · Citerat av 115 — Background: Perfluorinated chemicals (PFCs) have been used widely in perfluorooctane sulfonate (PFOS), perfluorohexane sulfate (PFHxS), 

PFOS was the key ingredient in Scotchgard, a fabric protector made by 3M, and numerous stain repellents. It was added to Annex B of the Stockholm Convention on Persistent Organic Pollutants in May 2009. Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that includes PFOA, PFOS, GenX, and many other chemicals. PFAS have been manufactured and used in a variety of industries around the globe, including in the United States since the 1940s. PFOA and PFOS have been the most extensively produced and studied of these chemicals. Exhibit 1: Physical and Chemical Properties of PFOS and PFOA (ATSDR 2015; EFSA 2008; EPA 2016b, 2016c) Property PFOS (Free Acid) PFOA (Free Acid) Chemical Abstracts Service (CAS) number 1763-23-1 335-67-1 Physical description (physical state at room temperature and atmospheric pressure) White powder (potassium salt) PFOA and PFOS are no longer manufactured or imported in the United States, but similar “replacement chemicals for PFOA and PFOS such as GenX, may be just as persistent,” Pinney said.

Children with high levels of PFOA and PFOS in their blood produce lower levels of antibodies after vaccination, which could reduce their ability to fight off infections. 3M, the primary manufacturer of PFOS, began a voluntary phase-out of the chemical in 2000.

These substances are synthetic compounds that … 2020-01-24 PFAS are a group of more than 4 700 man-made chemicals (OECD, 2018), the two most well-known of which are perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) (Box 1). Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that include Perfluorooctane Sulfonate (PFOS) and Perfluorooctanoic Acid (PFOA). These elements have a negative effect on the health of those exposed to them. PFOA and some closely related chemicals (such as PFOS) are now no longer made in the US, although they are still made in some other countries and could potentially reach US consumers in certain types of products. In addition, many other PFAS are now in use, and new ones are still being developed. https:// ntp.niehs.nih.gov/ ntp/ ohat/ pfoa_pfos/ pfoa_pfosmonograph_508.pdf pdf icon external icon A large number of studies have examined possible relationships between levels of per- and polyfluoroalkyl substances (PFAS) in blood and harmful health effects in people.
